    review  challenge the Federal  Energy Regulatory Commission's
    ("FERC"  or  "the   Commission")  decision  to  conditionally
    approve  the merger  of  Northeast Utilities  ("NU") and  the
    Public Service  Company of  New Hampshire ("PSNH").   Certain
    joint petitioners  and intervenors1  contend that  FERC erred
    when it:  (1) held that the benefits of the merger outweighed
    its costs; and  (2) failed  to condition the  merger on  NU's
    waiver  of  single  participant  status ("SPS")  in  the  New
    England Power Pool ("NEPOOL").  A group of public and private
    electric  utilities,  state   commissions,  state   agencies,
    independent  power producers,  cogenerators and  electric end
    users2  claim that  FERC  erred when  it:   (1)  allowed  the
    consummation of  the merger upon  the filing of,  rather than
    upon   approval  of,   a  transmission   tariff;  (2) adopted
    1   Joint petitioners and intervenors include:  Central Maine
    Power  Company; Boston Edison  Company; Bangor Hydro-Electric
    Company;  the  Towns  of  Concord,  Norwood  and   Wellesley,
    Massachusetts;    Maine    Public    Utilities    Commission;
    Massachusetts   Department   of  Public   Utilities;  Vermont
    Department of Public  Service; Vermont Public Service  Board;
    Rhode  Island Attorney  General;  Rhode  Island  Division  of
    Public  Utilities  and   Carriers;  Massachusetts   Municipal
    Wholesale  Electric  Company;  and,  City of  Holyoke  Gas  &
    Electric Department.
    2    This group  of petitioners and  intervenors includes the
    joint petitioners and intervenors  listed in n.1, supra (with
    the  exception of  Central Maine  Power Company),  and:   The
    American  Paper  Institute,   Inc.;  American  Public   Power
    Association;  Canal  Electric Company;  Commonwealth Electric
    Company;  Cambridge  Electric  Light  Company;  Massachusetts
    Attorney General; and, Montaup Electric Company.

    transmission   access  conditions  that  gave  "native  load"
    customers  a priority over  other customers; and (3) endorsed
    "opportunity  cost" pricing  principles.   The Holyoke  Gas &
    Electric Department ("Holyoke")  argues that FERC  erred when
    it  failed  to:   (1) conduct  an  appropriate review  of the
    environmental impact  of the  proposed merger; and,  (2) make
    findings    regarding    allegations    of    anticompetitive
    consequences  of  the merger  that  were  unique to  Holyoke.
    Finally,  Northeast  Utilities   Service  Company   ("NUSCO")
    asserts that FERC's orders  changing the terms of  three rate
    schedules  filed in  conjunction with its  merger application
    were arbitrary, capricious, and an abuse of discretion.
    For   the   reasons   which   follow,   we   reject
    petitioners' arguments and affirm the  Commission's decisions
    with the exception of the Commission's decision to change the
    terms  of the  Seabrook Power  Contract which  we  remand for
    consideration under the "public interest" standard.
    I.   BACKGROUND.
    A.   Parties to the Approved Merger.
    Northeast  Utilities ("NU") is a registered holding
    company under the Public Utility Holding Company  Act of 1935
    (PUHCA).  15 U.S.C.   79 et seq. (1988).  Northeast Utilities
    Service Company ("NUSCO") is  a service company subsidiary of
    -7-
    NU   and  supplies  centralized  administrative  and  support
    services to NU's operating companies.3
    Prior to the merger,  Public Service Company of New
    Hampshire ("PSNH")  was the  largest electric utility  in New
    Hampshire, supplying  electric service to some 375,000 retail
    customers,  approximately  three-quarters   of  the   State's
    population, in every county in the State.  PSNH also provided
    wholesale service to the New  Hampshire Electric Cooperative,
    three  New Hampshire  municipalities, and  one investor-owned
    utility,  Vermont  Electric  Power  Company.   PSNH  had  the
    largest  ownership  share,  approximately  35.6  percent,  of
    Seabrook Unit  No. 1, a nuclear  generating facility declared
    to be available for service on June 30, 1990.
    B.   The Merger Proposal.
    On  January  28,  1988,  PSNH   filed  a  voluntary
    petition  in  the  United  States Bankruptcy  Court  for  the
    District of New Hampshire for reorganization under Chapter 11
    of  the Bankruptcy Code.   11 U.S.C.    1101 et  seq. (1988).
    PSNH  alleged that it was unable to  recover in its rates the
    outlays  it had made in the construction and operation of the
    Seabrook  nuclear power  plant.   On  April  20, 1990,  after
    3    NU's operating companies are Connecticut Light and Power
    Company  (CL&P),  Western  Massachusetts   Electric  Company,
    Holyoke  Water  Power  Company (HWP)  and  HWP's wholly-owned
    subsidiary, Holyoke Power and Electric Company (HP&E).  These
    companies are wholly-owned subsidiaries  of NU and are public
    utilities supplying retail and wholesale electric service  in
    Connecticut and Massachusetts.
    -8-
    sifting through several  competing reorganization plans,  the
    bankruptcy court  approved NU's  proposal to merge  with PSNH
    and to  acquire and operate  all of PSNH's  power facilities.
    See In re Public Service Co. of New Hampshire, 
    963 F.2d 469
    ,
    470 (1st Cir.), cert.  denied, Rochman v. Northeast Utilities
    Service Co., 
    113 S. Ct. 304
     (1992).
    NU's proposal contained a two-step process:  first,
    PSNH would  emerge from  bankruptcy as a  stand-alone company
    bound  to a merger agreement  with NU; second,  PSNH would be
    merged  with   an  NU  subsidiary  created   solely  for  the
    acquisition (NU Acquisition Corporation), with  PSNH emerging
    as  the surviving entity.  After  the merger, PSNH would be a
    wholly-owned  subsidiary   of  NU  and  would   transfer  its
    ownership  interest   in  Seabrook  to  a   newly  formed  NU
    subsidiary,   North   Atlantic  Energy   Corporation  ("North
    Atlantic").    The second  step  would occur  only  after all
    necessary  approvals   were   received  from   the   relevant
    regulatory agencies.
    C.   Procedural History.
    On January 8, 1990, NUSCO, on behalf of NU and NU's
    operating subsidiaries, filed an  application with FERC under
    section 203 of  the Federal  Power Act ("FPA"),  16 U.S.C.
    824b (1988), seeking authorization for PSNH to dispose of all
    of its  jurisdictional facilities and  concurrently to  merge
    with, and become  a subsidiary  of, NU.   In connection  with
    -9-
    this application,  NUSCO filed four rate  schedules with FERC
    pursuant to    205 of the FPA:  the Seabrook Power Contract,4
    the   Sharing  Agreement5   and   two  Capacity   Interchange
    Agreements.6
    The  Commission  consolidated consideration  of the
    merger  application and  rate  schedules,  accepted the  rate
    schedules for  filing and suspended their  effectiveness, and
    set for  hearings before an administrative  law judge ("ALJ")
    the questions  of whether the  Commission should grant  the
    203  application  and  approve   the  rate  schedules.    See
    Northeast Utilities Service Co.,  50 F.E.R.C.   61,266, reh'g
    granted  in part  and denied  in part,  51 F.E.R.C.    61,177
    (1990).  In its order, the Commission directed the parties to
    4  The  Seabrook Power Contract  is a life-of-the-unit  power
    sales agreement between PSNH  and North Atlantic entered into
    concurrently with  NU's acquisition of PSNH  and the transfer
    of PSNH's share  of Seabrook  to North Atlantic.   Under  the
    contract, PSNH  agreed  to purchase  North Atlantic's  entire
    share of Seabrook capacity and  energy, according to a  cost-
    of-service formula rate.  The contract was intended to ensure
    that  North Atlantic would recover all of its costs from PSNH
    regardless of whether or not Seabrook actually operated.
    5   The Sharing Agreement allocates the benefits and obliga-
    tions from the  integrated operation of PSNH and  the current
    NU  system, as well as  the joint planning  and operations of
    these  systems.   This  agreement established  a formula  for
    sharing the  expected post-merger benefits that  would accrue
    to NU and PSNH  operating companies as a result  of operating
    efficiencies  and  the  ability  to take  single  participant
    status under the NEPOOL agreement.
    6   The  two Capacity Interchange Agreements provide  for the
    sale  and purchase  of  energy between  PSNH and  Connecticut
    Light & Power Company (CL&P) over a ten-year term.

    address  the  effect of  the proposed  merger on  NU's market
    power and "whether any transmission conditions  are necessary
    to eliminate any  adverse effect of the  proposed merger and,
    if  so,  what specific  conditions  should be  imposed."   50
    F.E.R.C. at 61,834-35.
    On December  20, 1990,  the ALJ issued  its Initial
    Decision  approving  the     203  application  and  the  rate
    schedules   with   certain   modifications  and   conditions.
    Northeast Utilities Service Co., 53 F.E.R.C.   63,020 (1990).
    The Commission, in Opinion No. 364, issued on August 9, 1991,
    affirmed in  part and  reversed in part  the ALJ's  decision,
    conditionally approving  the    203 application and  the rate
    schedules.   Northeast Utilities  Service Co., 56  F.E.R.C.
    61,269  (1991).    On  January 29,  1992,  after  considering
    additional  filings  by  the  parties and  oral  argument  on
    transmission  pricing issues,  the Commission  issued Opinion
    No. 364-A,  affirming its  conditional approval of  the   203
    application  and rate schedules.  Northeast Utilities Service
    Co., 58 F.E.R.C.   61,070 (1992).
    Petitions for review of  Opinions No. 364 and 364-A
    were  filed in  this court  and in  the District  of Columbia
    Circuit  Court.     The  Judicial   Panel  on   Multidistrict
    Litigation  consolidated these petitions  for review  in this
    court, where  further petitions for  review were  filed.   28
    U.S.C.   2112(a) (1988).  Subsequently, in Opinion No. 364-B,
    -11-
    the Commission denied a request for  rehearing of Opinion No.
    364-A.  Northeast Utilities Service Co., 59 F.E.R.C.   61,042
    (1992).  A petition for review of Opinions No. 364-A and 364-
    B was filed in this court, where it was consolidated with the
    earlier filed  petitions.  We review  the Commission's orders
    under the jurisdiction established by 16 U.S.C.   825l.
    II.  STANDARD OF REVIEW.
    On  review,   we  give   great  deference  to   the
    Commission's decision.   U.S. Dep't of Interior  v. FERC, 
    952 F.2d 538
    , 543  (D.C. Cir. 1992).  FERC's findings of fact are
    reviewed under the "substantial evidence" standard of review.
    16 U.S.C.   825l  ("The finding of  the Commission as to  the
    facts,  if  supported  by  substantial  evidence,  shall   be
    conclusive.").  Therefore,
    [w]e  defer  to  the agency's  expertise,
    particularly where the statute prescribes
    few specific standards  for the agency to
    follow,  so  long  as  its   decision  is
    supported  by  "substantial evidence"  in
    the  record  and  reached   by  "reasoned
    decisionmaking," including an examination
    of  the  relevant  data  and  a  reasoned
    explanation   supported   by   a   stated
    connection  between  the facts  found and
    the choice made.
    Electricity  Consumers  Resource Council  v.  FERC, 
    747 F.2d 1511
    ,  1513 (D.C. Cir. 1984).  "Pure" legal errors require no
    deference  to agency  expertise,  and are  reviewed de  novo.
    Questions involving an interpretation of the FPA involve a de
    novo determination  by the court of  Congressional intent; if
    -12-
    that  intent is  ambiguous,  FERC's conclusion  will only  be
    rejected if  it  is unreasonable.    Chevron USA  v.  Natural
    Resources  Defense  Council,

    , 363 (1st Cir. 1988).
    III. DISCUSSION.
    A.   Conditional Approval of the Merger.
    1.   Background.
    In reaching  his  decision to  approve the  NU-PSNH
    merger,  the   ALJ  found  that  the   merger  would  produce
    significant benefits.  Specifically, he found that:  (1) PSNH
    would emerge from bankruptcy  as a viable utility on  a solid
    financial  footing,  53  F.E.R.C.  at  65,211;  (2)  improved
    management techniques and economies of scale would reduce the
    operating costs  of Seabrook by  some $527  million,7 id.  at
    65,212; (3) application of NU operating procedures  to PSNH's
    fossil steam plants would save  $100 million, id. at  65,213;
    (4) reductions in  administrative and general  expenses would
    save  $124  million, id.;  (5) NU's  record of  buying lower-
    priced coal on the  spot market would save $39  million, id.;
    and (6) the merger would yield $360 million in savings for NU
    because of  its ability to elect  "single participant status"
    7   This, and all other dollar amounts are net present values
    unless otherwise noted.
    -13-
    in  the  New  England  Power  Pool  (NEPOOL),  a  power  pool
    comprised of most of the utilities in New England.  Id.
    The ALJ  also found that  unless several conditions
    were  imposed, the  merger  would have  short- and  long-term
    anticompetitive consequences because of the  merged company's
    increased market  power over  key transmission  facilities in
    both  the New England region and the Rhode Island and Eastern
    Massachusetts submarket ("Eastern  REMVEC").  53 F.E.R.C.  at
    65,214-19.   Under the  authority of   203(b)  of the FPA, 16
    U.S.C.    824b(b), the  ALJ  approved the  merger subject  to
    several conditions, including the  following:  (1) the merged
    company  must  offer  firm  (non-interruptible)  transmission
    service  for a minimum of 30 days  and a maximum of 20 years,
    53  F.E.R.C.  at  65,220-21;  (2) non-firm  service  must  be
    offered  for a one-day minimum  term, id. at  65,220; (3) the
    merger would be consummated concurrently with the filing of a

    2.   The Statutory Standard.
    FERC's   authority   to    consider   the    merger
    applications of utilities  is set  forth in    203(a) of  the
    FPA, 16  U.S.C.   824b(a):  the Commission  "shall approve" a
    proposed merger of utility facilities if, "[a]fter notice and
    opportunity  for hearing, . . . the Commission finds that the
    proposed disposition, consolidation, acquisition,  or control
    will  be  consistent with  the public  interest."   
    Id.
       The
    Commission has the additional authority to grant approval for
    such transactions "upon such terms and conditions as it finds
    necessary   or  appropriate  to  secure  the  maintenance  of
    adequate service and the  coordination in the public interest
    of facilities subject to the jurisdiction of the Commission."
    16 U.S.C.     824b(b).    As the  Commission  noted  when  it
    reviewed the Initial Decision of the ALJ,
    [m]erger  applicants need not show that a
    positive  benefit  will  result   from  a
    proposed  merger.    The  applicant  must
    fully  disclose  all  material facts  and
    show  affirmatively  that  the merger  is
    consistent with the public interest.   It
    is  sufficient  if  the "probable  merger
    benefits  . . .  add up  to substantially
    more than the costs of the merger."
    56 F.E.R.C. at  61,994 (quoting  Utah Power &  Light Co.,  47

    Pacific Power  & Light Co.  v. Federal Power  Commission, 
    111 F.2d 1014
    ,  1016 (9th  Cir. 1940).    We review  the record,
    therefore, to determine whether the Commission's finding that
    -17-
    the   probable   benefits   of   the  NU-PSNH   merger   were
    substantially  more   than   its  costs   was  supported   by
    substantial evidence.
    3.   Discussion.
    Petitioners make two claims  with regard to  FERC's
    evaluation  of the costs and benefits  of the NU-PSNH merger.
    First,  they  argue  that  the  Commission  should  not  have
    included resolution of PSNH's bankruptcy as a  benefit of the
    merger because:  (1) PSNH actually emerged from bankruptcy on
    May 16, 1991, the  effective date of the  Reorganization Plan
    ("RP");  and  (2) prior  to  gaining  the bankruptcy  court's
    approval  of the two-step RP, PSNH  had to show that it would
    be  financially  viable  as   a  stand-alone  entity  because
    regulatory approval  for the  second step  of the  RP (merger
    with and into NU) was not assured.  These two facts, however,
    do not  imply that  it was  error for  FERC  to consider  the
    "resolution of PSNH's bankruptcy" as  a benefit, indeed as  a
    principal benefit, of the merger.
    It  is  true  that  PSNH, as  a  technical  matter,
    "emerged" from  bankruptcy prior  to FERC's  consideration of
    the proposed merger.  The ALJ and the Commission did not hold
    otherwise.   The  ALJ  stated, and  the Commission  summarily
    affirmed the fact that "[t]he merger is part of  a plan which
    enables a  reorganized PSNH to  emerge from bankruptcy."   53
    F.E.R.C. at 65,211  (emphasis added); see also 56 F.E.R.C. at
    -18-
    61,993.  Like the state regulators  who approved the two-step
    merger  plan, the Commission  evaluated the plan  as a whole,
    anticipating  "the merger   not  `stand alone' PSNH    as the
    ultimate destiny  for the reorganized company."   53 F.E.R.C.
    at 65,211.   "All parties to  the reorganization contemplated
    [stand  alone]  status as  an interim  step  en route  to the
    merger."  
    Id.
       It was the entire  plan, which admittedly had
    two  sequential and  severable  steps, that  allowed PSNH  to
    emerge  from bankruptcy.  There is no evidence that the state
    regulators would have approved a plan to allow PSNH to emerge
    from bankruptcy  that included  only the first  "stand alone"
    step.  Indeed, there is evidence to the contrary.
    FERC  also found that "resolving" PSNH's bankruptcy
    meant  more  than  simply  the emergence  of  PSNH  from  the
    protection of  bankruptcy court.   FERC held  that the  final
    resolution of PSNH's bankruptcy included the treatment of its
    creditors and  stockholders who stood  to lose  approximately
    $250 million  in  the absence  of  the merger.    As the  ALJ
    observed, the Commission "regard[s] the right of these public
    bondholders as of primary importance after the consumers have
    been protected."  53 F.E.R.C. at 65,211 (quoting In re Evans,
    1 F.P.C. 511, 517  (1937) (approving an acquisition involving
    the reorganization  of a bankrupt utility)).   The Commission
    also held that it was  in the public interest to  approve the
    creation  of a  stronger, more  viable merged  entity, rather
    -19-
    than leaving PSNH in a "weakened", "stand alone" state.  This
    holding was sufficiently supported by evidence in the record.
    Petitioners also  claim that, given  the bankruptcy
    court's   "feasibility   finding"  required   by   11  U.S.C.
    1129(a)(11),12  the Commission  was estopped  from reaching
    the  conclusion that a "stand  alone" PSNH would  be "weak."
    We disagree.   The  bankruptcy court  and FERC evaluated  the
    merger proposal under  different standards.   The  bankruptcy
    court  was required  to determine  the likelihood  of further
    liquidation or reorganization proceedings were the plan to be
    approved.  FERC was obliged to determine whether the plan was
    "consistent  with   the  public   interest."    It   was  not
    inconsistent for FERC to find that although PSNH was  capable
    of  surviving  as  a stand  alone  entity,  it  would not  be
    "consistent  with the  public interest"  to prevent  a merger
    that  would  result   in  an  even  stronger  utility.    The
    principles of estoppel simply do not apply  in a case such as
    this, where the issues litigated and the standards applied in
    the two proceedings are so different.
    12   The Bankruptcy Code provides that:
    (a)   The   court   shall  confirm   a   plan   [of
    reorganization]  only  if   all  of  the  following
    requirements are met:
    (11) confirmation  of the plan is not  likely to be
    followed  by  the  liquidation,  or  the  need  for
    further financial reorganization, of the  debtor or
    any successor to the  debtor under the plan, unless
    such liquidation  or reorganization is  proposed in
    the plan.
    11 U.S.C.   1129(a)(11).
    -20-
    Even were petitioners correct in their asseveration
    that  FERC  improperly  counted  the  resolution   of  PSNH's
    bankruptcy  as a  benefit  of the  merger, "the  Commission's
    error would be immaterial in light of the overwhelming excess
    of other  benefits ($791  million) over  the costs  (0) still
    attributable . . . to the acquisition."   City of Holyoke Gas
    & Elec. Dep't v. S.E.C., 
    972 F.2d 358
    , 362 (D.C. Cir. 1992).
    Second,  petitioners  argue that  FERC  erred  as a
    matter  of law  in  weighing as  merger  benefits results  or
    alleged  savings   that  were,  or  could   be,  achieved  by
    "alternate  means."   Specifically, petitioners  contend that
    FERC's   failure  to   apply  the   "alternate   means"  test
    contradicted  general agency  policy  and  general  antitrust
    principles.
    It is undisputed  that utilities  are "not  immune"
    from antitrust laws.   Otter Tail Power Co. v. U.S., 
    410 U.S. 366
    ,  372-75 (1973); Town  of Concord  v. Boston  Edison, 
    915 F.2d 17
     (1st  Cir.  1990), cert.  denied,  
    111 S. Ct. 1337
    (1991).  At issue in this case is whether FERC is required by
    statute,  or otherwise,  to  engage  in "standard"  antitrust
    analysis before  passing on    203  merger applications.   In
    claiming that  FERC has such an  obligation, petitioners rely
    on a statute  governing agency approval of  bank mergers (the
    -21-
    "Bank  Merger  Act")  which   states  that  the  agency  with
    jurisdiction over a proposed bank merger,13
    shall not approve
    (A)  any  proposed merger  transaction
    which  would result  in  a  monopoly,  or
    which  would  be  in furtherance  of  any
    combination  or conspiracy  to monopolize
    or  to attempt to monopolize the business
    of  banking in  any  part  of the  United
    States, or
    (B)   any    other   proposed   merger
    transaction whose effect  in any  section
    of  the country  may be  substantially to
    lessen  competition, or to tend to create
    a monopoly, or which in any  other manner
    would be in restraint of trade, unless it
    finds that the anticompetitive effects of
    the  proposed   transaction  are  clearly
    outweighed in the public interest  by the
    probable  effects  of the  transaction in
    meeting the convenience  and needs of the
    community to be served. . . .
    (6)   The    responsible   agency   shall
    immediately  notify the  Attorney General
    of any  approval by  it pursuant  to this
    subsection    of   a    proposed   merger
    transaction.
    12 U.S.C.   1828(c)(5)-(6).   The Supreme Court, interpreting
    the Bank Merger Act, has held that before a bank merger which
    is  injurious to  the  public interest  may  be approved,  "a
    showing [must] be made that the gain expected from the merger
    cannot  reasonably be expected through other means."  U.S. v.
    Phillipsburg Nat. Bank & Trust Co., 
    399 U.S. 350
    , 372 (1970).
    Petitioners claim that the language of the Bank Merger Act is
    sufficiently similar to the statute governing FERC's approval
    13   Jurisdiction varies  depending on whether  the resulting
    entity  is  a national  bank, a  state  member bank,  a state
    nonmember bank, or a savings association.
    -22-
    of  proposed  mergers,  16  U.S.C.    824b(a),  because  both
    contain  a "public interest" standard, to require FERC to use
    the "alternate means" test which  bank regulators must use in
    evaluating proposed bank mergers.  We disagree.
    As with  any matter  of statutory construction,  we
    first examine the language  of the statute.  Under  16 U.S.C.
    824b(a),  the  Commission  is required,  after  notice  and
    opportunity  for hearing,  to  approve a  proposed merger  of
    utility  facilities if  it finds  that the proposal  "will be
    consistent  with  the  public interest."    That  is all  the
    statute  says.  There  is no explicit  reference to antitrust
    policies or principles.   There is no  evidence that Congress
    sought  to  have  the  Commission  serve  as  an  enforcer of
    antitrust  policy  in  conjunction  with  the  Department  of
    Justice and  the Federal Trade  Commission.  The  Bank Merger
    Act  reveals a  quite different  intention.   There, Congress
    explicitly  set out  standards for  approval of  bank mergers
    that incorporate  principles  embodied  in  the  Sherman  and
    Clayton  Acts.   12  U.S.C.   1828(c)(5).   By  requiring the
    reviewing  agency  to  notify  the Attorney  General  of  any
    decision  to approve  a  proposed bank  merger,  12 U.S.C.
    1828(c)(6),  Congress  expressed  its  desire  to  have  bank
    regulators  serve as pre-screening  bodies of  mergers which,
    because of their importance or character, in most  cases also
    deserve the attention of the Department of Justice.
    -23-
    The Bank  Merger Act  carries with it  the implicit
    presumption that  mergers are  to be disapproved  (the agency
    "shall not approve" a  bank merger "unless it finds  that the
    anticompetitive  effects are clearly outweighed in the public
    interest"  by   the  benefits   of  the  merger,   12  U.S.C.
    1828(c)(5)).   The  FPA,  on the  other hand,  requires the
    Commission to approve any merger that is "consistent with the
    public  interest."     16   U.S.C.     824b(a).     Antitrust
    considerations   are,   of   course,   relevant   in   FERC's
    consideration of  the "public interest"  in merger proposals.
    The  statute,  however,  does  not require  FERC  to  analyze
    proposed mergers under the same standards that the Department
    of Justice or bank regulators must apply.
    Although  the  Commission  must  include  antitrust
    considerations in its public interest calculus under the FPA,
    it is not  bound to use antitrust principles when they may be
    inconsistent  with the  Commission's  regulatory goals.   See
    Otter  Tail,   
    410 U.S. at 373
      ("[a]lthough   antitrust
    considerations  may be  relevant [in  determining  the public
    interest], they are not determinative").  In Town of Concord,
    this  court  observed  that indiscriminate  incorporation  of
    antitrust policy into utility regulation  "could undercut the
    very objectives  the antitrust  laws are designed  to serve."
    
    915 F.2d at 22
    .     Therefore,  "antitrust  analysis  must
    sensitively `recognize and  reflect the distinctive  economic
    -24-
    and  legal  setting' of  the regulated  industry to  which it
    applies."   
    Id.
     (quoting Watson &  Brunner, Monopolization by
    Regulated   "Monopolies":     The   Search  for   Substantive
    Standards, 22 Antitrust Bull. 559, 565 (1977)).
    Petitioners  may  rest  assured that  were  FERC to
    approve  a merger of utilities which ran afoul of Sherman Act
    or other  antitrust policies, the utilities  would be subject
    to either prosecution by government officials responsible for
    policing the antitrust laws,  or to suit by private  citizens
    meeting the requirements  of standing.   See Otter Tail,  
    410 U.S. at 374-5
    .
    B.   FERC's  Failure to Condition  Merger on NU's Waiver
    of Single Participant Status.
    Petitioners  argue  that  the  Commission  erred in
    failing to  condition the merger on waiver  by NU and PSNH of
    "single participant status" ("SPS")  in the New England Power
    Pool ("NEPOOL"), thereby preventing  the imposition of a $364
    million cost shift  from NU and PSNH to  the other members of
    NEPOOL.
    1.   Background.
    NEPOOL is  a power  pool comprised  of most  of the
    utilities in New England.  The association is governed by the
    New England  Power  Pool Agreement  ("the  Agreement")  which
    establishes a "comprehensive interconnection and coordination
    arrangement" among  its members in order  "to achieve greater
    -25-
    reliability and economies in the  production of electricity."
    Groton v.  FERC,  
    587 F.2d 1296
    ,  1298  (D.C.  Cir.  1978).
    Section  202(a)  of the  Federal  Power  Act encourages  such
    voluntary  interconnection  and  coordination of  electricity
    generating facilities in order to achieve economies of scale.
    16  U.S.C.    824a; see  also 16  U.S.C.    824a-1 (regarding
    pooling  agreements).  The Agreement  was approved as a filed
    rate  schedule  by  FERC's  predecessor,  the  Federal  Power
    Commission.   53 F.E.R.C. at  65,213.  Under  its terms, each
    member  is  required  to   supply  the  pool  with  resources
    ("Capacity Responsibility") according to a formula based upon
    the  relationship of the member's peak load to an estimate of
    aggregate peak load of all members.
    NU  experiences its  peak load  in the  summer, and
    PSNH experiences its peak load in the winter.  By aggregating
    these two,  complementary, peak loads, NU-PSNH  can achieve a
    lower Capacity Responsibility than would  be the case if  the
    two   utilities  remained  separate.    Because  the  overall
    capacity requirements of NEPOOL  will not change as  a result
    of the merger, the Capacity Responsibilities of other members
    must rise to  make up  for the savings  accruing to  NU-PSNH.
    The  ALJ  accepted  the  "undisputed" estimate  that  "single
    participant status" (SPS)  will result in a  shifting of some
    $360  million in costs from  NU-PSNH to other  members of the
    pool.

    2.   Discussion.
    Petitioners  offer six  arguments to  support their
    claim that FERC erred  in failing to condition the  merger on
    waiver of SPS by NU and PSNH.  First, petitioners  claim that
    the Commission  did not  properly interpret the  provision of
    the NEPOOL Agreement which  governs the election of SPS.   We
    agree with  the Commission's finding that  the Agreement both
    specifically allows for the election  by NU-PSNH of SPS,  and
    encourages  such elections.    Section 3.1  of the  Agreement
    provides in relevant part that:
    All  Entities which  are controlled  by a
    single person (such as a corporation or a
    common law business  trust) which owns at
    least seventy-five percent of  the voting
    shares   of   each  of   them   shall  be
    collectively   treated    as   a   single
    Participant   for    purposes   of   this
    Agreement, if they elect  such treatment.
    They are  encouraged to  do so.   Such an
    election shall  be  made by  signing  the
    appropriate   form  at   the  end   of  a
    counterpart of this Agreement.
    (Emphasis  supplied.)    Both  the  ALJ  and  the  Commission
    interpreted section 3.1 to be  an explicit endorsement of the
    election of  SPS by NU-PSNH.   The  ALJ stated that  "[i]t is
    undisputed  that  NU  and   PSNH  qualify  for  such  [single
    participant]  status under  the Agreement."   53  F.E.R.C. at
    65,213.  The Commission  gave great weight to the  unrebutted
    testimony  of  witness  Bigelow,   who  participated  in  the
    negotiation of  the NEPOOL Agreement regarding  the intent of
    the  original  signatories   to  the   Agreement  and   their
    -28-
    recognition  of  such  potentially  large  cost-shifts  among
    NEPOOL members.  Bigelow stated:
    [W]hen  we put  NEPOOL together  20 years
    ago,  we  recognized  that  these  things
    might happen.  This is not something that
    snuck  up  on people. . . .   And  we did
    discuss  at  length  what   would  happen
    because . . . we were then coming up to a
    potential   merger   of  Boston   Edison,
    Eastern Utilities, New England Power.  It
    was recognized that these kinds of things
    could happen in the future and we spelled
    out the ground rules and  recognized that
    that would  happen when it happened.  And
    the  people   who  didn't  like   it  got
    something else for it.
    53  F.E.R.C.  at 65,214.   Both  the  ALJ and  the Commission
    rejected petitioners' claim on the basis of both the language
    of the Agreement, and Bigelow's unrebutted testimony that not
    only  had the  signatories been  aware of such  a potentially
    large  savings  shift, but  that  those  utilities that  were
    dissatisfied  with this risk  received additional concessions
    as  compensation.    We  will not  disturb  the  Commission's
    findings.
    Second,  petitioners claim  that the  Agreement, as
    interpreted in  NEPOOL Power Pool Agreement,  56 F.P.C. 1562,
    1580 (1976), aff'd sub nom. Municipalities of Groton v. FERC,
    
    587 F.2d 1296
     (D.C. Cir. 1978), prohibits utilities with peak
    loads  in different  seasons  from  electing  SPS.    As  the
    Commission  explained,  this  argument  mischaracterizes  the
    Agreement and  the decision  of the Federal  Power Commission
    ("FPC") in NEPOOL.
    -29-
    The NEPOOL Agreement, as  initially filed
    and    as   approved,    allowed   single
    participant    status    for    utilities
    controlled by a single "person" owning at
    least 75 percent of the voting shares  of
    each utility.  An exception was expressly
    allowed  in the  filed agreement  for any
    Vermont  utility  which  elected   to  be
    grouped   with  Vermont   Electric  Power
    Company.  This exception was approved for
    essentially two reasons:  (1) the Vermont
    utilities  had  long  acted  as  a single
    contiguous  integrated  electric  entity;
    and (2) since  they all experienced their
    peak loads in winter,  single participant
    status would not give them a lower NEPOOL
    Capability Responsibility (and consequent
    savings).    A   broader  exception   was
    denied, however, for a group of municipal
    utilities (represented by MMWEC) that was
    not entitled to single participant status
    and  that lacked the two cited attributes
    of the  Vermont utilities.  The basis for
    the denial was that allowing  such status
    for "any group of systems, such as MMWEC,
    could   well   be   detrimental  to   the
    functioning of NEPOOL."
    The  NEPOOL  decision, thus,  does not
    stand  for  the  proposition that  single
    participant status is  available only  to
    utilities  having their peak loads in the
    same  season.    Instead,   another  way,
    indeed   the   primary   way,  in   which
    utilities  may qualify  is  if  they  are
    controlled  by a  single  person with  at
    least 75-percent common ownership.   That
    is the basis upon  which NU and PSNH will
    presumably seek to  qualify if the merger
    is  approved.   Such status  is expressly
    allowed   under   the  NEPOOL   Agreement
    regardless of when NU and PSNH experience
    their peak loads.
    56 F.E.R.C. at 61,996-97.  The reasons  offered by the FPC in
    its  decision  to  grant  a  special  exception  for  Vermont
    utilities seeking SPS were  not intended to be, and  are not,
    conditions, in  addition to those  set out in  the Agreement,
    -30-
    which must be satisfied to elect SPS.  The FPC did not narrow
    the scope of Section  3.1 to apply only to  utilities sharing
    the  same peak  load  season; rather,  it  created a  special
    exception to the  75 percent rule  to accommodate the  unique
    situation faced by Vermont utilities.
    Third, petitioners  claim that FERC failed  to give
    proper consideration  to Section  4.2 of the  Agreement, "the
    interests of  other  pool members,  and  the purpose  of  the
    Agreement as  a whole."  Essentially,  petitioners argue that
    allowing  NU-PSNH  to  elect  SPS  would  violate  a  general
    provision  of the  Agreement, which states  that participants
    "shall  not . . . take  advantage of  the provisions  of this
    Agreement so  as to harm another Participant  or to prejudice
    the  position  of any  Participant  in  the electric  utility
    business."   We  reject  this argument  for the  same reasons
    expressed   by  the  Commission   in  its   decision  denying
    petitioners' request for a rehearing:
    [W]e  find more  relevance in  the NEPOOL
    Agreement's   explicit   endorsement   of
    single  participant  status  than in  the
    agreement's  general  goal of  "equitable
    sharing"   and  prohibition   on  members
    "taking  advantage"  of the  agreement to
    harm  or prejudice  other  members.   The
    NEPOOL Agreement  specifically encourages
    eligible    parties   to    seek   single
    participant status;  the provisions cited
    by  the  intervenors  are   general,  not
    specific.      Construing   the   general
    consistent  with  the  specific, we  find
    single participant status for  the merged
    company  consistent   with  an  equitable
    sharing,  as  envisioned  by  the  NEPOOL
    -31-
    Agreement, and not  violative of the  ban
    on  taking  advantage of  the agreement's
    provisions  to  harm  or prejudice  other
    members.
    58 F.E.R.C. at 61,189.   We agree with FERC's  interpretation
    of  the  Agreement.     The  NEPOOL  signatories   explicitly
    encouraged  qualified  members  to  seek  SPS,   indeed  they
    contemplated that members that merged might choose to do just
    that.   We agree  with the  Commission's construction  of the
    Agreement which avoids a direct conflict between Sections 3.1
    and 4.2, and instead gives both provisions reasonable effect.
    Fourth, petitioners argue that failure to condition
    the   merger  on   waiver  of   SPS  would   create  "serious
    disincentives"   for  current   members  to   continue  their
    membership  in NEPOOL,  and  that the  breakup  of NEPOOL  is
    contrary to the public interest.  Petitioners imply that FERC
    did not take seriously their complaints about SPS, but rather
    rested its decision  not to  require a waiver  solely on  the
    fact that the Agreement allowed the election of SPS.  This is
    simply not so.
    The  Commission reversed  the ALJ  on the  issue of
    whether SPS savings  should be  counted as a  benefit of  the
    merger.   The Commission  found that  because the  cost shift
    amounted  to  a  zero-sum   transaction,  with  NU  and  PSNH
    benefitting and the other members burdened dollar-for-dollar,
    the shift could not  be counted as a  benefit of the  merger.
    -32-
    56  F.E.R.C. at 61,997.  Thus, the Commission did not dismiss
    petitioners' claims regarding SPS without thought.
    Also,  the ALJ  found,  and the  Commission agreed,
    that SPS was essential to the merger, and that the merger, as
    conditioned, was in the public interest.  FERC must approve a
    proposed merger if it is consistent with the public interest.
    16  U.S.C.    824b(a).    FERC  has  the  discretion  to  add
    conditions  to a proposed  merger to  ensure that  the merger
    will, taken as a whole, be in the public interest.  16 U.S.C.
    824b(b).    FERC  need  not, however,  explain  why  every
    condition, or failure to  establish a condition is consistent
    with the public interest when considered separately and apart
    from the entire transaction.  Petitioners seem to argue  that
    FERC was required by law to  state why it was consistent with
    the  public interest  to  follow the  explicit  terms of  the
    approved fifteen  year-old  NEPOOL Agreement  rather than  to
    condition  the  merger  on   waiver  of  a  membership  right
    established by the Agreement.   FERC had no such  obligation.
    It need not have  explained why it failed to add a particular
    condition  prior to approving  a merger.   The statute simply
    provides that "[t]he Commission may grant any application for
    an order under this section in whole or in part and upon such
    terms and conditions as it  finds necessary or appropriate to
    secure the  maintenance of adequate  service and coordination
    in  the   public  interest  of  facilities   subject  to  the
    -33-
    jurisdiction  of the Commission."   16 U.S.C.    824b(b).  In
    this  case, the Commission  set forth a  reasonable basis for
    approving the  merger as consistent with  the public interest
    in light of the supplementary conditions the Commission found
    necessary.   FERC  need not  have gone  further than  this to
    explain  why it  failed  to place  further conditions  on the
    merger.
    Fifth,   petitioners   allege   that   FERC   acted
    inconsistently in  its  treatment of  the NEPOOL  Agreement's
    provisions regarding  voting rights and SPS.   The Commission
    adopted  a  condition limiting  the  merged company's  NEPOOL
    voting  rights to  prevent PSNH  and NU  from gaining  a veto
    power  in NEPOOL.  56  F.E.R.C. at 62,043-45.   FERC reasoned
    that,  while   there  was   evidence  that   the  signatories
    anticipated  that  large   cost-shifts  would  accompany  the
    election  of SPS in merger  situations, there was no evidence
    that they anticipated the  voting rights implications of such
    mergers.   58 F.E.R.C.  at 61,189.   It was not,  contrary to
    petitioners' argument,  inconsistent as a matter  of logic to
    condition voting rights where the Agreement was silent on the
    need or lack of need to do so, while failing to condition SPS
    where the  Agreement explicitly favored the  election of SPS.
    Furthermore, it was not  an error of law to  condition voting
    rights while  leaving SPS  rights untouched.   Petitioners do
    not  contest the Commission's decision to condition NU-PSNH's
    -34-
    voting  rights.    We  will uphold  whatever  conditions  the
    Commission  imposes on  a proposed  merger  so long  as their
    necessity is supported in the record by substantial evidence.
    Finally,  petitioners  contend that  the Commission
    "failed to  explain why  burdening other NEPOOL  members with
    $364 million in additional  costs with no offsetting benefits
    to them is consistent  with the public interest."   In making
    this argument, petitioners imply that each and every piece of
    a complex package of merger agreements and conditions must be
    able to  withstand "public interest"  analysis without regard
    to other pieces of the package or to other conditions imposed
    by  the  Commission.   Petitioners  also  imply that  if  any
    individual or group is harmed by a piece of the package, that
    provision is not in the public interest and must therefore be
    stricken  or modified.   Both  implicit arguments  are deeply
    flawed.
    In  evaluating a  transaction  such as  the one  at
    issue  here, the  Commission  is required  to  find that  the
    entire transaction, taken as a whole,  is consistent with the
    public interest.  16 U.S.C.    824b(a).  Each element of  the
    transaction  need not  benefit  every  utility or  individual
    which might  be affected; rather, the  whole transaction must
    be consistent with the interest of "the public."  There is no
    reason  to  think  that  the interest  of  individual  NEPOOL
    members is  synonymous with  the "public"  interest.  As  has
    -35-
    already been noted,  FERC may  add conditions  to a  proposed
    merger before granting approval.   16 U.S.C.   824b(b).   The
    statute  does  not  require,  however,  that  FERC  establish
    conditions so  that every effect of an  approved merger could
    withstand the "public interest" test.
    At  a less  theoretical level,  the ALJ  determined
    that the NEPOOL savings  "were a vital  part of the long  and
    strenuous negotiations which culminated in the resulting PSNH
    reorganization plan,"  and  the particular  savings  of  $146
    million   for  New   Hampshire   consumers  were   relied  on
    specifically by the  State of New Hampshire in  approving the
    merged company's rate package.   53 F.E.R.C. at 65,213.   The
    Commission accepted this  finding of the  ALJ, while, at  the
    same time, it reversed  the ALJ's decision to count  the $360
    million as  a benefit of the merger.   58 F.E.R.C. at 61,997.
    The fact that  the cost-shift was not a benefit to be counted
    in weighing the  benefits and  costs of the  merger does  not
    mean that  the election of SPS and the concomitant cost-shift
    is not in  the public interest.   Election of  SPS is in  the
    public interest because it is a central element of the merger
    plan  which, viewed  as  a whole,  was  found by  FERC  to be
    consistent  with  the public  interest  based  on substantial
    evidence in the record.  We approve the Commission's decision
    not to condition the merger on waiver by NU of SPS.
    C.   Timing of Merger's Consummation.
    -36-
    In  the  proceedings before  the  ALJ,  NU proposed
    filing  a transmission  tariff within  60 days  following the
    merger.  Intervenors and Commission staff proposed the filing
    and  approval of  an  interim  transmission  rate.   The  ALJ
    rejected  both proposals  and  instead held  that the  merger
    would  be  consummated upon  the  filing  of NU's  compliance
    tariff.  He reasoned as follows:
    I see no  need for  requiring one  tariff
    (with potential for controversy, charges,
    collections and refunds)  to be  followed
    by  yet  another  tariff,  with  its  own
    potential for still other disputes.
    Avoiding  a  transitional period  will
    make   it   unnecessary   to  require   a
    transitional  tariff.    To achieve  this
    result, consummation of  the merger  must
    be conditioned on  the concurrent  filing
    of  a  compliance   tariff  which   fully
    reflects all of  the terms and conditions
    set out in this Initial Decision.  Such a
    condition should encourage  a prompt  and
    fair compliance filing  because NU  could
    not begin  to  reap the  merger  benefits
    without it.
    53 F.E.R.C. at 65,221.  The Commission concurred:
    We    believe    the   GTC    [General
    Transmission   Conditions]  and   the  NH
    Corridor  Proposal,  as modified  herein,
    adequately    mitigate    the    merger's
    anticompetitive effects without requiring
    the adoption of the Merger Tariff.  Trial
    Staff stated that the Merger Tariff would
    make  service available  immediately upon
    approval of the merger.   We believe that
    the presiding judge accomplished the same
    result  by  allowing consummation  of the
    merger  when  NU  submits its  compliance
    filing.
    We further believe  that delaying  the
    merger's    consummation    until     the
    Commission   accepts    NU's   compliance
    -37-
    submittal    for    filing    would    be
    inappropriate   given   the   uncertainty
    surrounding    issues   which    may   be
    challenged   and   subject   to   further
    litigation  in the  compliance proceeding
    and  given our  commitment to  act before
    the Merger Agreement's December  31, 1991
    termination date.  We believe that NU and
    PSNH are  entitled to  a prompt and  fair
    resolution  of this  proceeding.   At the
    same time the intervenors are entitled to
    have service begin as soon  as practical,
    together  with a  fair resolution  of any
    disputes raised regarding NU's compliance
    filing.  Accordingly, we believe  that it
    is in the best  interests of all  parties
    to allow NU to consummate the merger when
    it submits  its  compliance filing.    We
    shall also require  NU to begin  honoring
    such  requests  for transmission  service
    under the  GTC,  as modified  herein,  at
    that  time.    Such transmission  service
    will be  provided at  either the firm  or
    non-firm  transmission rates  proposed in
    NU's   compliance   filing,  subject   to
    refund, and  without a refund  floor.  In
    reviewing    NU's   filing    to   ensure
    compliance  with  this  Opinion, we  will
    hold  NU to a very high  standard.  As NU
    itself  states, "[i]f NU  fails to comply
    with  the  letter   or  spirit  of   such
    [Commission]  requirement,  NU  would  be
    subject to summary judgment  with respect
    to any aspect of its compliance filing."
    56 F.E.R.C. at 62,025.
    Petitioners'  stated concern  is that,  by allowing
    the  merger to be consummated prior to FERC's approval of the
    compliance tariff, FERC did not provide a sufficient guaranty
    that NU would provide transmission access that would mitigate
    -38-
    the  merger's  anticompetitive  effects.14    Petitioners  do
    not, however,  seek  to unravel  the  merger.   Rather,  they
    propose that any  cost shift under the  NEPOOL Agreement, see
    discussion in  Part III(B),  supra, be postponed  until after
    the compliance tariff is approved.  Petitioners complain that
    the course chosen by FERC creates an incentive on the part of
    NU  to delay  proceedings on  the compliance  tariff, thereby
    maximizing  competitive  advantage.   Petitioners do  not, of
    course,  point  out  that  their  proposal  would  create  an
    incentive  on  their  part to  delay  final  approval of  the
    compliance tariff, thereby postponing the day when the NEPOOL
    cost shift will take effect.
    The ALJ and the Commission carefully considered the
    alternatives before reaching their decisions.  The Commission
    held that the anticompetitive effects of the merger  would be
    adequately  mitigated  by  the  dual  requirements   that  NU
    immediately provide  transmission access upon  the filing  of
    its compliance  tariff, and  that any  fees  collected by  NU
    would be subject to  refund without a refund floor.   Because
    NU  accepted  these  merger conditions,  the  Commission  can
    enforce NU's  promise to pay  such refunds if  the Commission
    finds them to be appropriate.  See Distrigas of Massachusetts
    Corp. v.  FERC, 
    737 F.2d 1208
    , 1225 (1st  Cir. 1984).   
    FERC 14
       We  note that,  at oral  argument, petitioners  conceded
    that no one  had as  yet sought access  to NU's  transmission
    facilities.
    -39-
    explicitly  warned NU  that  "[i]n reviewing  NU's filing  to
    ensure compliance with  this Opinion,  we will hold  NU to  a
    very high standard."  56 F.E.R.C. at 62,025.
    The Commission balanced the merging companies' need
    for a "prompt  and fair resolution" of  the merger proceeding
    against the intervenors' need "to have [transmission] service
    begin  as soon as practical,  together with a fair resolution
    of any disputes raised  regarding NU's compliance filing." 56
    F.E.R.C.  at 62,025.    An  agency's  discretion  is  at  its
    "zenith" when  it fashions remedies to  effectuate the charge
    entrusted to it by Congress.   Niagra Power Corp. v. FPC, 
    379 F.2d 153
    ,  159 (D.C. Cir.  1967).  See also,  Consolo v. FMC,
    
    383 U.S. 607
    , 620-21  (1966); Environmental Action,  Inc. v.
    FERC, 
    939 F.2d 1057
    , 1064 (D.C. Cir. 1991); Boston Edison Co.
    v. FERC,  
    856 F.2d 361
    ,  371 (1st Cir.  1988).  We  hold that
    FERC's exercise  of its  discretion was not  inappropriate in
    these  circumstances.   FERC  did not  defer, as  petitioners
    suggest,  consideration of the anticompetitive effects of the
    merger  which  FERC  itself   identified.    The   Commission
    recognized the effects, and dealt with them in a reasoned way
    which  balanced  the  competing  interests  of  all  parties.
    FERC's remedy  is not  unreasonable, and we  therefore affirm
    its order.
    D.   Protection of Native Load Customers.
    1.   Priority of Services.
    -40-
    a.   Background.
    In its  merger  application, NU  made  a  voluntary
    commitment   to   provide  wholesale   transmission  service,
    including third  party wheeling  service,15  for any  utility
    over  its existing transmission system.  At the same time, NU
    sought  to limit  this  obligation by  reserving an  absolute
    priority  for  power  purchases  on  behalf  of  native  load
    customers (whose  power  needs NU  is bound  by franchise  or
    contract  to  meet).   The  ALJ  held  that  although NU  may
    reasonably give  native load service  priority over  wheeling
    service if NU's transmission system had insufficient capacity
    to serve both, 53  F.E.R.C. at 65,221-222, NU could  not deny
    firm  wheeling   requests  based  upon  the   reservation  of
    transmission  capacity for  its  own non-firm  sales, id.  at
    65,225.
    In Opinion  No.  364, the  Commission balanced  the
    interests of  native load customers and  third party wheeling
    customers  and  affirmed  the  ALJ's denial  of  an  absolute
    priority:
    we  .  . .  deny  NU's  proposal to  give
    higher priority to  its own non-firm  use
    than  to third  party  requests for  firm
    wheeling    in     allocating    existing
    transmission  capacity.    In  no  event,
    however, will  NU be required  to provide
    firm third party wheeling service  out of
    existing   transmission   facilities   if
    15   For a definition of "wheeling" see n.9, supra.
    -41-
    reliability  of  service  to native  load
    customers would be adversely affected.
    56  F.E.R.C. at  62,021 (footnote  omitted).   The Commission
    found it "reasonable to allow NU to reserve firm transmission
    capacity  to  provide reliable  service  to  its native  load
    customers."  Id. (Emphasis in original.)
    On rehearing,  NU asked the  Commission to  clarify
    the  scope of  the "reliability"  criterion.   The Commission
    "reiterate[d] that under no circumstances will NU be required
    to provide firm wheeling service out of existing transmission
    capacity where  doing so would impair  or degrade reliability
    of  service to native load customers."  58 F.E.R.C. at 61,199
    (emphasis  removed).   The  Commission  held  the concept  of
    reliability generally  encompasses the:   (1) reservation  of
    transmission capacity to back  up large generating units; (2)
    provision of generation reserves; and (3) coverage of certain
    future  needs.     As  to  the  coverage   of  future  demand
    requirements, the Commission  specifically ordered that  "any
    capacity needed for reliability purposes  within a reasonable
    planning horizon  must be offered  for wheeling use  until NU
    expects  to need the capacity  for reliability reasons."  Id.
    at 61,199-200.
    Petitioners assert  that the  decision to accord  a
    priority to native load  over transmission load is arbitrary,
    discriminatory, and  anticompetitive.   They argue  that FERC
    neither  defined  nor  justified  the   priority  granted  by
    -42-
    allowing reservation of transmission capacity for native load
    service  and  that  any  such  priority  creates  competitive
    advantages for  NU.  We  hold that the  Commission adequately
    defined and reasonably justified its decision to allow such a
    reservation  and  properly   addressed  the   anticompetitive
    concerns raised by the intervenors.
    b.   Discussion.
    Although the Commission reaffirmed the general rule
    that  firm transmission service  should be  accorded priority
    over  non-firm  service, even  if  the  latter would  benefit
    native load,    it nonetheless  allowed  NU to  reserve  firm
    transmission capacity  needed to ensure reliability of native
    load  service and allowed the  use of this  capacity for non-
    firm transactions.  58 F.E.R.C. at 61,196.  Thus, native load
    service will receive  a "priority" over third-party  wheeling
    service  in  allocating existing  transmission  capacity when
    reliability  of service  to  native load  would be  adversely
    affected.     The  Commission  specifically   qualified  this
    priority by requiring NU  to offer the capacity  for wheeling
    use until NU needed  it to assure reliability to  native load
    customers.
    There  is nothing arbitrary or discriminatory about
    FERC's decision.  It struck  a reasonable balance between the
    competing interests of native load customers and  third-party
    wheeling customers.  NU-PSNH is obligated to serve its native
    -43-
    load  customers.  In return for this obligation to serve, the
    native load customers regularly bear the cost of transmission
    facilities;  native load  customers pay  for them,  use them,
    plan  on them, and rely on them.   As the ALJ noted, "[e]very
    New England utility favors  its own native load.   Nothing in
    the NEPOOL agreement requires  its members to surrender their
    native load preference, and none do."  53 F.E.R.C. at 65,222.
    Thus,  "NU should be allowed  to give priority  over safe and
    reliable service to its  native load customers using existing
    transmission capacity  built to  serve those customers."   58
    F.E.R.C. at  61,199.   FERC explicitly defined  and justified
    the challenged native load "priority."
    2.   Transmission Upgrades Pricing.
    a.   Background.
    NU's commitment to provide third-party transmission
    service   includes   the  obligation   to   build  additional
    transmission facilities as necessary to  relieve transmission
    constraints on  its system.   58  F.E.R.C.  at 61,204-10;  56
    F.E.R.C. at 62,021-24.   The issue  then becomes, how  should
    the  cost  of  constructing  such  transmission  upgrades  be
    allocated.  The ALJ stated  that questions of cost allocation
    are  best  addressed  in  future  proceedings  regarding  the
    particular   responsibilities   for  particular   facilities.
    Nevertheless,  the ALJ  adopted  the "but  for" analysis  for
    determining responsibility proposed by NU witness Schultheis:
    -44-
    [W]heeling customers must make a pro rata
    contribution   whenever  the   facilities
    would  not have been  needed but  for the
    wheeling  transfers across  a constrained
    interface.   This means that  NU's native
    load customers pay for the new facilities
    they  create  the need  for  and wheeling
    customers  pay  for  the facilities  they
    create the need for.
    53 F.E.R.C. at 65,223.  The ALJ also noted that the financial
    exposure of  transmission customers  was limited by  the cost
    caps  to  which NU  was committed.16    Id. at  65,224.   The
    Commission agreed that cost  questions should be litigated in
    the context of a specific proposal,  and accepted the concept
    of  the "but for" test  as a framework  for ascertaining cost
    responsibility and the  use of  the proposed cost  caps as  a
    reasonable  means of  limiting  the  transmission  customers'
    responsibility for  future upgrades.  56  F.E.R.C. at 62,028-
    030.   The Commission reaffirmed that  decision on rehearing.
    58 F.E.R.C. 61,204-207.
    Petitioners  contend that the  Commission failed to
    adequately  explain  the pricing  policy  it  will employ  in
    pricing  transmission upgrades.  Basically, petitioners claim
    the ruling is too ambiguous to determine whether, or how, the
    16  NU committed  to cap  cost responsibility  to "(1)  those
    specific facilities  identified  by NU  at  the time  of  the
    wheeling request as needing to be built or upgraded either at
    the time of the request or in the future; and (2) the maximum
    dollar  amount  contained  in  NU's  initial  estimate  of  a
    wheeling customer's pro  rata share  of the  costs of  future
    upgrades  needed  to  accommodate   a  request  for  wheeling
    service."

    Commission changed its  policy from the traditional  "rolled-
    in" approach used  in pricing transmission service.   We hold
    that   the  Commission   provided   a  clear   and   reasoned
    justification for  the principles that will  guide its future
    determinations of  transmission upgrade  pricing.  We  affirm
    the Commission's decision not  to modify the basic principles
    adopted in its order.
    b.   Discussion.
    In accepting as reasonable  the "but for" test, the
    Commission  has  done no  more than  approve a  framework for
    determining  cost responsibility  which furthers  the general
    principle that  transmission costs  should be borne  by those
    entities  responsible  for the  cost.    58 F.E.R.C.  61,205.
    Under  this test,  incremental  cost pricing  could be  found
    appropriate when firm wheeling across  a particular interface
    would  degrade reliability absent  upgrades.   The Commission
    specifically declined, however, to answer the requests of the
    intervenors  to  decide  the "rolled-in  versus  incremental"
    rate17 issue in  the abstract and  chose instead to  evaluate
    it only within the  context of a particular rate  proposal or
    upgrade.  Id.   The Commission articulated  how it envisioned
    17  Under "rolled  in" pricing principles, the upgrade  costs
    would  be rolled in with  other company costs  and charged to
    all ratepayers as part of NU's  general rate structure; while
    administratively   simple,   it   ignores  any   concept   of
    responsibility.  Thus, incremental pricing principles look to
    hold parties responsible for their share of upgrade costs.
    -46-
    pricing  transmission  upgrades   and  adopted  a   condition
    limiting  the  amount  NU  may  propose  to  collect  from  a
    transmission customer to the greater of
    (1) the incremental  cost of new  network
    facilities  required  at  the   time  the
    customer's new transmission load is added
    or (2) the rolled-in cost of  all network
    facilities required to serve the combined
    transmission loads of [NU], including any
    required transmission additions.
    Id. at 61,206.   Thus, a wheeling customer may be charged the
    greater of rolled-in cost rates or incremental cost rates.
    The Commission acknowledged  that the  introduction
    of incremental  cost pricing  principles is a  departure from
    its  traditional pricing  policies18 and  justified  this new
    policy  on NU's  unprecedented  obligation  to provide  third
    party transmission service.   Id.  The  Commission noted that
    incremental  cost  pricing  may  be  appropriate  in  certain
    circumstances,  but  decided to  leave  the  details of  cost
    responsibility  questions to  a  future specific  section 205
    rate case.  When such a  case arises, NU will bear the burden
    of   justifying  "any   direct  assignments   of   costs  and
    support[ing] any arguments that  reliability is degraded by a
    particular  firm transmission  service.    No presumption  is
    18     The  Commission generally  has  adhered to  rolled  in
    pricing,   but  has   never  precluded   particularized  cost
    allocations to  specific  customers where  appropriate.   See
    Utah Power & Light Co., 45 F.E.R.C.   61,095, at 61,291 n.163
    (1988);  Public Service Co. of Indiana, 51 F.E.R.C.   61,367,
    at 62,203 (1990).

    created  by  NU's  `but  for' criterion  that  firm  wheeling
    customers always cause the need for upgrades."  Id. at 61,207
    (quoting 56 F.E.R.C. at 62031).   The Commission also allowed
    that  any  reliance by  NU  upon the  "but  for" test  may be
    challenged in  future actions.   The Commission  sufficiently
    explained and  justified the  principles that will  guide its
    transmission upgrade pricing.
    E.   Opportunity Cost Pricing.
    As has already been discussed, the Commission found
    it necessary to impose a number of conditions on the proposed
    NU-PSNH merger to mitigate  the merged company's market power
    in the  markets for  transmission and short-term  bulk power.
    58 F.E.R.C.  at 61,195.    Specifically, the  Commission held
    that  NU  must  provide  firm  transmission  service  out  of
    existing  capacity  for  any   utility,  subject  only  to  a
    reservation  of  sufficient  capacity  to  maintain  reliable
    service to its  native load customers  and to honor  existing
    contractual obligations.   NU was  prohibited, however,  from
    denying a request for  firm transmission service by reserving
    capacity for  non-firm transactions  that would enable  it to
    provide more economical service to its native load customers.
    56 F.E.R.C.  at 62,014-21;  58 F.E.R.C. at 61,196-200.   FERC
    also  held   that  NU  must  build   additional  transmission
    facilities   as   needed   to   provide   transmission  where
    insufficient capacity  exists.  56 F.E.R.C.  at 62,021-24; 58
    -48-
    F.E.R.C. at 61,204-10.   The Commission found that  these and
    other conditions  would  "adequately mitigate"  the  merger's
    anticompetitive effects.  58 F.E.R.C. at 61,213.
    On rehearing, NU and  the States of Connecticut and
    New Hampshire  argued that the Commission  should address the
    issue of  firm transmission  pricing because, in  Opinion No.
    364, FERC  had established  principles governing  the related
    issue of  firm transmission priority which  made NU's ability
    to purchase  inexpensive power (which would lower its cost of
    serving  its  native  load  customers)  subordinate  to   its
    obligation  to provide  firm transmission for  third parties.
    58  F.E.R.C.  at  61,201-02.    The  Commission  agreed,  but
    declined  to approve  "opportunity  cost  pricing"19  outside
    the  context of  a specific  tariff proposal.   Instead,  the
    Commission announced three "basic  goals" to guide its future
    decisions on the  pricing of firm transmission service on the
    merged company's existing capacity, and left the door open to
    NU  to propose  a tariff  based on  opportunity costs  or any
    19   As the Commission explained, opportunity costs
    are the  revenues lost or  costs incurred
    by  a  utility  in providing  third-party
    transmission  service  when  transmission
    capacity is insufficient to  satisfy both
    a  third-party  wheeling request  and the
    utility's   own   use.     For   example,
    opportunity   costs  might   include  the
    revenues lost or costs incurred because a
    utility  must  reduce its  own off-system
    purchases or sales in order to overcome a
    constraint on the [transmission] grid.
    58 F.E.R.C. at 61,200-201.
    -49-
    other  methodology  that would  meet  the three  goals.   The
    Commission explained its decision as follows:
    We are now confronted with the need  to
    provide   NU   with  enough   specificity
    regarding  what it  will  be  allowed  to
    propose for the  pricing of future third-
    party  wheeling  service,  so   that  the
    company  can  decide  whether to  proceed
    with the  merger.  We also  cannot ignore
    the  need  to  act  as  expeditiously  as
    possible  given the  commercial realities
    and time pressures presented in corporate
    matters subject to our  jurisdiction, and
    in  particular  the  need  to  resolve  a
    bankruptcy situation.   At the  same time
    we are confronted with the need to ensure
    an  adequate record on pricing issues and
    to   afford   all  parties   an  adequate
    opportunity to voice their objections.
    Balancing  these  respective needs,  we
    conclude  that  the  best  course  is  to
    provide guidance on  pricing issues,  but
    to defer specific  pricing issues to  the
    compliance phase of  this proceeding,  or
    to subsequent cases where  the Commission
    may consider specific  proposals from  NU
    in a concrete, factual setting and with a
    more developed record.
    . . . .
    First, the  native load customers  of the
    utility  providing  transmission  service
    should   be   held  harmless.     Second,
    transmission customers  should be charged
    the lowest reasonable cost-based rate for
    third-party transmission service.  Third,
    the pricing should prevent the collection
    of  monopoly  rents  by the  transmission
    owner and  promote efficient transmission
    decisions.      In  ruling   on  specific
    proposed  rates,  we  will balance  these
    three  goals  in light  of the  facts and
    circumstances presented at that time.
    58 F.E.R.C. at 61,203 (emphasis added) (footnotes omitted).
    FERC  was careful  to  point out  that it  endorsed
    opportunity cost pricing  only insofar as NU  could show that
    -50-
    it could "propose rates which  include legitimate, verifiable
    opportunity costs."  Id.   The Commission warned NU  that any
    such  proposal would  be carefully  scrutinized and  would be
    subject to challenge.  Id. at 61,203-04.  Specifically,  FERC
    stated that  NU would  have to  address the  following issues
    should it seek recovery of opportunity costs:
    (1) whether opportunity  costs should  be
    capped by incremental expansion  costs or
    any  other  cap;   (2)  whether   current
    wheeling   and   wholesale   requirements
    customers  should be  treated differently
    from   future   wheeling  and   wholesale
    requirements    customers,    e.g.,    by
    receiving    "grandfather"   rights    to
    embedded cost  rates  for the  amount  of
    transmission  capacity they  already use;
    (3) how NU  will identify those customers
    responsible for growth on its  system and
    what   particular   new  facilities   are
    necessary to accommodate that growth; (4)
    whether  and how third  parties should be
    protected   from   uncertainty  regarding
    fluctuations  in  opportunity costs;  (5)
    how  the proposed rates  will prevent the
    collection of monopoly rents; and (6) how
    the  proposed  opportunity costs  will be
    verified.
    Id.    The Commission  expressly  postponed consideration  of
    whether opportunity cost pricing  would be inconsistent  with
    nondiscriminatory  pricing  and  nondiscriminatory terms  and
    conditions of  service until  those issues  were raised  in a
    concrete factual context.  Id. at 61,204, n.118.
    Petitioners claim that FERC's decision  amounted to
    an arbitrary endorsement of opportunity cost pricing that was
    not  supported  by evidence  in  the  record, was  inherently
    -51-
    discriminatory, and contrary to FERC's  regulation of natural
    gas pipelines.   Petitioners' underlying concern  seems to be
    that  when  the  issue arises  next  in  the  context of  the
    Commission's  review  of NU's  compliance  tariff, FERC  will
    simply approve the tariff and dismiss petitioners' objections
    on the  ground that  opportunity cost pricing  principles had
    already  been  endorsed  by  the  Commission.    Although  we
    understand petitioners' concerns,  we believe  that they  are
    misplaced and that FERC did not go as far as petitioners fear
    in endorsing opportunity cost pricing.
    Petitioners will have an opportunity to contest any
    compliance tariff proposed by NU.  The Commission itself laid
    out a number of issues which NU would have to address were it
    to  propose a tariff based on opportunity costs.  58 F.E.R.C.
    at 61,203.   Only  after carefully considering  the competing
    interests of providing  guidance to  NU as to  what kinds  of
    tariffs it would consider, and  the need to endorse  specific
    methodologies only on the  basis of a fully-developed record,
    did  the Commission  decide  to outline  broad pricing  goals
    which would allow  for a number of pricing  schemes including
    opportunity  cost pricing.  Id.   It was  squarely within the
    Commission's  power  to defer  consideration  of petitioners'
    assertions until  after NU filed  its compliance tariff.   As
    the  Supreme  Court  has  held,  "[a]n  agency  enjoys  broad
    discretion in determining how  to handle related yet discrete
    -52-
    issues  in  terms  of  procedures, and  priorities."    Mobil
    Exploration   &   Producing   Southeast,   Inc.   v.   United
    Distribution  Cos., 
    111 S. Ct. 615
    ,  627 (1991)  (citations
    omitted).   Petitioners argue that deferral was inappropriate
    in this case because  their objections went "to the  heart of
    the  public interest  determination  to be  made."   Maryland
    People's Counsel v. FERC, 
    761 F.2d 768
    , 778 (D.C. Cir. 1985).
    We disagree.
    The   Commission   announced   pricing  goals   and
    conditions  that   it  determined  would   keep  the   merger
    consistent  with the  public  interest, and  would result  in
    "just and  reasonable rates."   Until NU proposed  a specific
    tariff regime, the Commission did not have a developed record
    to evaluate on the  merits.  The Commission remains  free to,
    and  we expect it will, invite  objections to NU's compliance
    tariff from  affected parties,  and will reject  any proposed
    tariff that  conflicts with its  statutory responsibility  to
    approve rates  that are "just and reasonable," and to approve
    mergers that are, as conditioned, "consistent with the public
    interest."
    F.   Environmental Impact Statement.
    The  City of  Holyoke  Gas  &  Electric  Department
    ("HG&E") alleges that FERC's refusal to examine the potential
    environmental  impacts  of its  approval  of  the merger  was
    arbitrary and capricious.  We disagree.
    -53-
    The National Environmental  Policy Act of 1969,  42
    U.S.C.    4321 et seq., ("NEPA") requires federal agencies to
    consider the  potential environmental effects  of a  proposed
    major  federal  action  that  may  significantly  affect  the
    quality of the human environment.   Section 102(2)(C) of NEPA
    states:
    The Congress authorizes and directs that,
    to the  fullest extent  possible:  . .  .
    (2) all    agencies   of    the   Federal
    Government shall
    . . . .
    (C)  include  in every  recommendation or
    report on proposals  for legislation  and
    other major Federal actions significantly
    affecting  the  quality   of  the   human
    environment, a detailed statement  by the
    responsible official on
    (i)  the  environmental  impact of  the
    proposed action,
    (ii) any  adverse environmental effects
    which  cannot  be   avoided  should   the
    proposal be implemented,
    (iii)  alternatives   to  the  proposed
    action,
    (iv)  the  relationship  between  local
    short-term uses of man's  environment and
    the maintenance and enhancement  of long-
    term productivity, and
    (v) any  irreversible and irretrievable
    commitments of resources  which would  be
    involved in the proposed action should it
    be implemented.
    42  U.S.C.    4332(2)(C).   Agencies  were authorized,  under
    guidelines  promulgated  by  the  Council   on  Environmental
    Quality ("CEQ"), to create categorical exclusions for actions
    which do not individually  or cumulatively have a significant
    effect  on  the human  environment.    40  C.F.R.     1507.3,
    1508.4.    FERC  adopted   such  a  category  of  exclusions,
    -54-
    including one for merger  approvals such as the one  at issue
    in this case.  That regulation states in pertinent part:
    (a) General  rule.  Except  as stated  in
    paragraph (b) of this section, neither an
    environmental    assessment    nor     an
    environmental  impact  statement will  be
    prepared  for  the following  projects or
    actions:
    . . . .
    (16) Approval of actions under sections
    4(b), 203, 204, 301,  304, and 305 of the
    Federal  Power  Act relating  to issuance
    and  purchase of  securities, acquisition
    or   disposition  of   property,  merger,
    interlocking directorates, jurisdictional
    determinations and accounting orders.
    18  C.F.R.    380.4(a)(16).    An  agency  need  not issue  a
    "finding  of  no  significant  impact"  in  cases  concerning
    matters that fall into a categorical exclusion.  40 C.F.R.
    1501.3, 1501.4, 1508.13.
    CEQ  guidelines  also  required  agencies  adopting
    categorical   exclusions   to   "provide  for   extraordinary
    circumstances in which a normally  excluded action may have a
    significant environmental effect."  40 C.F.R.   1508.4.  FERC
    made such provision in its regulations:
    (b)    Exceptions     to    categorical
    exclusions. (1) In accordance with 40 CFR
    1508.4, the Commission and its staff will
    independently    evaluate   environmental
    information  supplied  in an  application
    and  in  comments by  the public.   Where
    circumstances indicate that an action may
    be a major  Federal action  significantly
    affecting  the  quality   of  the   human
    environment, the Commission:
    (i) May require an environmental report
    or    other    additional   environmental
    information, and
    -55-
    (ii)  Will   prepare  an  environmental
    assessment  or  an  environmental  impact
    statement.
    (2) Such circumstances  may exist  when
    the action  may have an effect  on one of
    the following:
    (i) Indian lands;
    (ii) Wilderness areas;
    (iii) Wild and scenic rivers;
    (iv) Wetlands;
    (v) Units of  the National Park System,
    National   Refuges,   or  National   Fish
    Hatcheries;
    (vi)  Anadromous   fish  or  endangered
    species; or
    (vii)  Where the  environmental effects
    are uncertain.
    However, the existence of  one or more of
    the above will not  automatically require
    the submission of an environmental report
    or  the  preparation of  an environmental
    assessment  or  an  environmental  impact
    statement.
    18  C.F.R.     380.4(b).20    HG&E  argues  that  the NU-PSNH
    merger might  "alter mixes  of generation  in New  England by
    constraining  the locations for new plants."   HG&E points to
    the language of 18 C.F.R.   380.4(b)(1)(ii) in support of its
    position  that FERC was  compelled, at the  least, to explain
    why  it   was  not  obliged   to  perform  the   analysis  of
    environmental  effects required  by  NEPA.   HG&E also  cites
    FERC's  decision  in  Southern   California  Edison  Co.,  49
    F.E.R.C.     61,091  (1989)   (holding  that    380.4(b)  was
    triggered when approved merger would result in the dumping of

    applicable regulations cited above.

    hundreds of tons of additional air contaminants into the most
    polluted air in the United States).
    There was no evidence in the record of identifiable
    environmental harms that would likely result from the NU-PSNH
    merger.  The  fact that new generating  facilities might wind
    up  in different locations than  would have been  the case in
    the absence of  the merger does not approach in significance,
    because  its  significance  is  not quantifiable,  the  known
    effects of  the  merger between  Southern  California  Edison
    Company  and San  Diego Gas  & Electric  Company.   Thus, the
    factual  situation presented in Southern California Edison is
    completely distinguishable from that of this case.
    The   character  and   location   of   the   future
    environmental effects of the  NU-PSNH merger are so uncertain
    that  no  meaningful  environmental  review would  have  been
    possible, even had  FERC made the effort.  Here, FERC was not
    approving  a  regional  development  plan.    It  was  merely
    approving a merger between utility companies, albeit a merger
    involving  two  of  the  largest utilities  in  New  England.
    Energy  demand may increase in New England over the following
    decades, and the fact  of the merger may influence  how those
    needs  are met.  Nevertheless, any attempt by FERC to prepare
    an  EIS would  have involved  little more  than spinning  out
    multiple  hypothetical  development forecasts,  with multiple
    options  for   the  type,  amount  and   location  of  future
    -57-
    generating facilities.  See  Kleppe v. Sierra Club,  
    427 U.S. 390
    , 401-2 (1976).  Once concrete plans have been established
    for   the   construction   of  transmission   or   generating
    facilities, those  proposals will  be reviewed under  NEPA or
    the applicable state environmental review procedures.
    FERC  was justified  in  deciding  that neither  an
    environmental   assessment   nor   an  environmental   impact
    statement was required prior to approving the NU-PSNH merger.
    G.   HG&E's "Unique" Harm.
    HG&E also  contends that because it  relied on PSNH
    New Hampshire  Corridor facilities for over  one-third of its
    electricity supply,  it would be "uniquely  threatened" by NU
    in head-to-head competition for  large, industrial loads.  To
    protect    itself,   HG&E   requested   that   FERC   either:
    (1) disapprove  the merger;  (2) require  the  divestiture or
    restructuring of  NU's retail  business in Holyoke  (HWP); or
    (3) grant  HG&E  grandfather  rights to  PSNH  New  Hampshire
    Corridor transmission.  The ALJ rejected the "drastic remedy"
    of divestiture of HWP, stating that it was  "wholly uncalled-
    for  by anything in this record," and holding that HG&E would
    be  adequately  protected by  the  conditions  to the  merger
    designed   to   address   the  anticompetitive   effects   on
    transmission dependent  utilities ("TDUs").   53  F.E.R.C. at
    65,232.
    As the ALJ described,
    -58-
    [t]he  Transmission  Dependent  Utilities
    (TDUs) are  "entirely dependent on  NU or
    PSNH  for  their bulk  power transmission
    needs."  These  companies (most of  which
    involve municipal ownership) are  not big
    enough  to  own  or construct  sufficient
    generation to meet their loads.  As their
    brief states, they "are physically unable
    to  engage in any  bulk power transaction
    without using the NU or PSNH transmission
    systems.  Absent  economic access to NU's
    or  PSNH's  transmission facilities,  the
    TDU  cannot  survive  as  an  independent
    entity."   The  TDUs compete with  NU and
    PSNH in the wholesale bulk  power market;
    each   TDU,   like  NU/PSNH,   seeks  out
    attractive sources of  supply.  TDUs thus
    "are in  the  uneasy position  of  having
    their    only    source   of    essential
    transmission  service  in  the  hands  of
    their principal competitor."  These small
    companies,    uniquely    vulnerable   to
    possible  anticompetitive   conduct,  are
    entitled  to  some measure  of protective
    assurance regarding NU/PSNH's post merger
    conduct.
    53  F.E.R.C. at 65,232-33.   The ALJ held  that "[a]ll rates,
    terms and  conditions of NU/PSNH transmission  service to the
    TDUs in effect  on this date shall . .  . be maintained after
    the merger,  unless and until changes are  either agreed upon
    by  the merged  company and  the TDUs,  or authorized  by the
    Commission."  53 F.E.R.C. at 65,233.  In short, while finding
    that  TDUs  were  "uniquely  vulnerable"  to  anticompetitive
    conduct by NU-PSNH,  the ALJ  found that HG&E  had not  shown
    that  it was  entitled to  protections beyond those  given to
    TDUs  generally.    The  Commission agreed,  56  F.E.R.C.  at
    62,049,  but bolstered the protection for TDUs ordered by the
    -59-
    ALJ by imposing the additional condition  that NU establish a
    special tariff for TDUs.  Id. at 62,050.
    HG&E  points  to  no  evidence  in  the  record  to
    indicate  that it  faced anticompetitive consequences  of the
    merger sufficiently  different in  character or magnitude  to
    warrant greater  protections than those given  to other TDUs.
    We therefore affirm the Commission's actions to protect TDUs,
    which were adequately explained and supported in the record.
    H.   Modifications to the Filed Rate Schedules.
    The Commission analyzed the Seabrook Power Contract
    and Capacity Interchange Agreements  filed by NUSCO under the
    "just and reasonable"  standard of    206 of  the FPA,21  and
    ordered the  following modifications to  the rate  schedules:
    (1) deletion of the automatically adjusting rate of return on
    equity  provision  in  the   Seabrook  Power  Contract;   (2)
    reduction of the  rate of  return on equity  in the  Seabrook
    Power  Contract from  13.75 percent  to 12.53  percent;22 (3)
    21   Section  206(a)  of  the  FPA,  16  U.S.C.     824(e)(a)
    provides:
    Whenever the  Commission, after hearing
    had  upon   its   own  motion   or   upon
    complaint, shall find that any rate . . .
    collected by any public  utility . . . is
    unjust,        unreasonable,       unduly
    discriminatory   or   preferential,   the
    Commission shall determine  the just  and
    reasonable  rate . . .  to be  thereafter
    observed and in force, and shall  fix the
    same by order.
    22   NUSCO did not appeal this modification.
    -60-
    North  Atlantic's decommissioning expenses under the Seabrook
    Power Contract  and any subsequent changes  thereto were made
    subject to  review by  the Commission;  (4) reduction  in the
    rate  of return  on  equity  specified  in the  two  Capacity
    Interchange Agreements  from 14.50  percent to 13.17  percent
    for the period from July 27, 1990 through August 8, 1991, and
    thereafter  to  12.93 percent;  and  (5)  the Seabrook  Power
    Contract  could be modified  by the Commission  in the future
    under the "just and reasonable" standard of   206 of the FPA,
    rather than the "public  interest" standard agreed to  by the
    parties.  56 F.E.R.C. at 61,993; 58 F.E.R.C. at 61,185.
    Each  of the  three parties  to the  Seabrook Power
    Contract ("SPC"), NU,  PSNH and the  State of New  Hampshire,
    waived  its right to file  a complaint under    206 regarding
    the rates contained in the agreement.  Section 12 of  the SPC
    also provided that:
    [E]ach [party] further agrees that in any
    proceeding  by the FERC under Section 206
    the  FERC  shall   not  change  the  rate
    charged under this Agreement  unless such
    rate  is found  to  be  contrary  to  the
    public interest.
    NU argues  that the Commission  violated the  "Mobile-Sierra"
    doctrine23 when  it  modified the  SPC  in disregard  of  the
    intent of the parties.
    23   This doctrine is based on the  companion cases of United
    Gas Pipe Line  Co. v. Mobile  Gas Service Co.,  
    350 U.S. 332
    (1956)  and FPC  v. Sierra  Pacific Power  Co., 
    350 U.S. 348
    (1956).
    -61-
    Under  the  Mobile-Sierra doctrine,  the Commission
    must respect certain private  contract rights in the exercise
    of its  regulatory powers.  Parties  to a contract may:   (1)
    waive  their  rights to  file  a  complaint challenging  that
    contract,  and (2) restrict  the power  of the  Commission to
    impose rate changes  under   206 to  cases in which it  finds
    the  rates contrary to the public interest   a more difficult
    standard  for  the  Commission  to meet  than  the  statutory
    "unjust and  unreasonable" standard  of    206.   See  Papago
    Tribal Utility Authority  v. FERC,  
    723 F.2d 950
    , 953  (D.C.
    Cir. 1983), cert. denied,  
    467 U.S. 1241
     (1984).   In Papago,
    the court held  that, regardless of the  parties' intent, the
    Commission retained, in any event,
    the indefeasible right . . . under    206
    to replace rates that are contrary to the
    public interest, "as where  [the existing
    rate   structure]    might   impair   the
    financial ability of  the public  utility
    to continue its  service, cast upon other
    consumers  an  excessive  burden,  or  be
    unduly discriminatory."
    Papago, 
    723 F.2d at 953
    , (quoting Sierra, 
    350 U.S. at 355
    ).
    The court  went on to  note that  "unduly discriminatory"  in
    this  context  "apparently  means  unduly  discriminatory  or
    preferential  to  the detriment  of  purchasers  who are  not
    parties to the contract."  Papago, 
    723 F.2d at
    953 n.4.
    In  this case,  seemingly for  the first  time, the
    Commission held that it also had the
    -62-
    authority   under  the   public  interest
    standard to  modify a contract where:  it
    may   be  unjust,   unreasonable,  unduly
    discriminatory  or  preferential  to  the
    detriment  of  purchasers  that  are  not
    parties to  the contract;  it is  not the
    result  of arm's length bargaining; or it
    reflects  circumstances where  the seller
    has  exercised  market  power   over  the
    purchaser.
    50  F.E.R.C. at 61,839 (emphasis added).  The ALJ interpreted
    that holding as follows:
    The  Commission  made clear  that  in the
    particular circumstances  surrounding the
    Seabrook  contract,  it  retains power
    through the "public interest"  language
    to    make   modifications    under   the
    traditional   just  and   reasonable  and
    nondiscrimination standards.
    53 F.E.R.C.  at  65,235.   The  standard established  by  the
    Commission, and  subsequently applied by  the ALJ,  conflates
    the  "just and  reasonable" and "public  interest" standards,
    thereby  circumventing  the  Mobile-Sierra  doctrine.     The
    distinction  between the  "just and  reasonable" and  "public
    interest"  standards  loses  its   meaning  entirely  if  the
    Commission may  modify a  contract under the  public interest
    standard  where it  finds  the contract  "may be  unjust [or]
    unreasonable."   The  parties'  express intent  was to  avoid
    review  of  rate  schedules  under the  just  and  reasonable
    standard.    Mobile-Sierra protects  their  right  to do  so,
    leaving the Commission  with the power  to modify rates  only
    when required by the public interest.
    -63-
    The  Commission  found that  the  SPC  might unduly
    discriminate  against entities not  parties to  the contract,
    and that there was no genuine arm's-length bargaining because
    NU and PSNH negotiated the agreement at a time when they knew
    they were about to  merge and have identical interests.   The
    Commission held  that, in  this context, it  could "carefully
    scrutinize the  rates, terms and conditions  of the contract"
    to determine if they were just.  
    Id.
    The Commission's  explanation for employing  a just
    and  reasonable  standard seems  to  us inadequate.    To the
    extent  the  Commission   is  relying  on   NU's  prospective
    ownership of PSNH, it is unclear why the Commission should be
    concerned    about   protecting   PSNH   from   a   perceived
    disadvantageous arrangement imposed by its  prospective owner
    since any disadvantage visited on  the prospective subsidiary
    will be borne by its owner.  If NU chooses  to allocate risks
    among its operating subsidiaries  and one of its subsidiaries
    is  disfavored in  this calculation,  there would seem  to be
    little justification for the Commission stepping in on behalf
    of the disfavored subsidiary absent some threat to the public
    interest.
    As for the seller's  market power, reliance on this
    factor  threatens  to  erode  the  Mobile-Sierra doctrine  so
    substantially that  a fuller explanation  from the Commission
    is required before  proceeding down this  route.  After  all,
    -64-
    some  measure of  market power  could be  present in  a large
    number  of  contracts.    A  case-by-case  inquiry  into  the
    presence  and extent of market  power would inject  a new and
    potentially  time-consuming  element  into the  Mobile-Sierra
    analysis, and it is not entirely  clear in any event why  the
    Commission should protect a buyer who voluntarily enters into
    an agreement with a dominant seller.
    The  most attractive case  for affording additional
    protection, despite  the presence of a contract, is where the
    protection is  intended to  safeguard the interests  of third
    parties,  notably the  buyer's customers.   The Mobile-Sierra
    doctrine itself allows  for intervention by FERC  where it is
    shown  that the  interests of  third parties  are threatened.
    Mobile,  350  U.S.  at  344-45;  Sierra,  
    350 U.S. at 355
    .
    However, the  standard to be  applied, as  formulated by  the
    Supreme  Court, is  the  protection of  outside parties  from
    "undu[e] discriminat[ion]"  or  imposition of  an  "excessive
    burden."  Sierra,  
    350 U.S. at 355
    .  If  there is some reason
    for departing from this public interest standard as framed by
    the Supreme Court, the Commission has not supplied it.
    We  assume, without  deciding, that:   (1)  FERC is
    correct  in its assertion that the State of New Hampshire did
    not adequately represent the  interests of non-parties to the
    contract,  and  that,  therefore,  the SPC  may  have  unduly
    discriminated  against those non-parties; and (2) the alleged
    -65-
    lack of arms'-length bargaining among NU,  PSNH and the State
    of  New Hampshire gave  the Commission the  right to evaluate
    the SPC.  We hold, however,  that the Commission was bound to
    follow  the Mobile-Sierra  doctrine as explicated  by Papago,
    and therefore should have evaluated  the SPC under the public
    interest standard, not the just and reasonable standard.
    We  therefore remand this issue for reconsideration
    by FERC under the public interest standard.24
    IV.  SUMMARY.
    We affirm  the Commission's orders in  all respects

    review  challenge the Federal  Energy Regulatory Commission's
    ("FERC"  or  "the   Commission")  decision  to  conditionally
    approve  the merger  of  Northeast Utilities  ("NU") and  the
    Public Service  Company of  New Hampshire ("PSNH").   Certain
    joint petitioners  and intervenors25 contend that  FERC erred
    when it:  (1) held that the benefits of the merger outweighed
    its costs; and  (2) failed  to condition the  merger on  NU's
    waiver  of  single  participant  status ("SPS")  in  the  New
    England Power Pool ("NEPOOL").  A group of public and private
    electric  utilities,  state   commissions,  state   agencies,
    independent  power producers,  cogenerators and  electric end
    users26  claim  that FERC  erred when  it:   (1)  allowed the
    consummation of  the merger upon  the filing of,  rather than
    upon   approval  of,   a  transmission   tariff;  (2) adopted
    25     Joint petitioners  and intervenors  include:   Central
    Maine  Power Company;  Boston Edison  Company; Bangor  Hydro-
    Electric  Company;   the  Towns  of   Concord,  Norwood   and
    Wellesley, Massachusetts; Maine Public  Utilities Commission;
    Massachusetts   Department   of  Public   Utilities;  Vermont
    Department of Public  Service; Vermont Public Service  Board;
    Rhode  Island Attorney  General;  Rhode  Island  Division  of
    Public  Utilities  and   Carriers;  Massachusetts   Municipal
    Wholesale  Electric  Company;  and,  City of  Holyoke  Gas  &
    Electric Department.
    26   This  group of petitioners and intervenors  includes the
    joint petitioners and intervenors  listed in n.1, supra (with
    the  exception of  Central Maine  Power Company),  and:   The
    American  Paper  Institute,   Inc.;  American  Public   Power
    Association;  Canal  Electric Company;  Commonwealth Electric
    Company;  Cambridge  Electric  Light  Company;  Massachusetts
    Attorney General; and, Montaup Electric Company.

    transmission   access  conditions  that  gave  "native  load"
    customers  a priority over  other customers; and (3) endorsed
    "opportunity  cost" pricing  principles.   The Holyoke  Gas &
    Electric Department ("Holyoke")  argues that FERC  erred when
    it  failed  to:   (1) conduct  an  appropriate review  of the
    environmental impact  of the  proposed merger; and,  (2) make
    findings    regarding    allegations    of    anticompetitive
    consequences  of  the merger  that  were  unique to  Holyoke.
    Finally,  Northeast  Utilities   Service  Company   ("NUSCO")
    asserts that FERC's orders  changing the terms of  three rate
    schedules  filed in  conjunction with its  merger application
    were arbitrary, capricious, and an abuse of discretion.
    For   the   reasons   which   follow,   we   reject
    petitioners' arguments and affirm the  Commission's decisions
    with the exception of the Commission's decision to change the
    terms  of the  Seabrook Power  Contract which  we  remand for
    consideration under the "public interest" standard.
    I.   BACKGROUND.
    A.   Parties to the Approved Merger.
    Northeast  Utilities ("NU") is a registered holding
    company under the Public Utility Holding Company  Act of 1935
    (PUHCA).  15 U.S.C.   79 et seq. (1988).  Northeast Utilities
    Service Company ("NUSCO") is  a service company subsidiary of
    -7-
    NU   and  supplies  centralized  administrative  and  support
    services to NU's operating companies.27
    Prior to the merger,  Public Service Company of New
    Hampshire ("PSNH")  was the  largest electric utility  in New
    Hampshire, supplying  electric service to some 375,000 retail
    customers,  approximately  three-quarters   of  the   State's
    population, in every county in the State.  PSNH also provided
    wholesale service to the New  Hampshire Electric Cooperative,
    three  New Hampshire  municipalities, and  one investor-owned
    utility,  Vermont  Electric  Power  Company.   PSNH  had  the
    largest  ownership  share,  approximately  35.6  percent,  of
    Seabrook Unit  No. 1, a nuclear  generating facility declared
    to be available for service on June 30, 1990.
    B.   The Merger Proposal.
    On  January  28,  1988,  PSNH   filed  a  voluntary
    petition  in  the  United  States Bankruptcy  Court  for  the
    District of New Hampshire for reorganization under Chapter 11
    of  the Bankruptcy Code.   11 U.S.C.    1101 et  seq. (1988).
    PSNH  alleged that it was unable to  recover in its rates the
    outlays  it had made in the construction and operation of the
    Seabrook  nuclear power  plant.   On  April  20, 1990,  after
    27   NU's operating companies are Connecticut Light and Power
    Company  (CL&P),  Western  Massachusetts   Electric  Company,
    Holyoke  Water  Power  Company (HWP)  and  HWP's wholly-owned
    subsidiary, Holyoke Power and Electric Company (HP&E).  These
    companies are wholly-owned subsidiaries  of NU and are public
    utilities supplying retail and wholesale electric service  in
    Connecticut and Massachusetts.
    -8-
    sifting through several  competing reorganization plans,  the
    bankruptcy court  approved NU's  proposal to merge  with PSNH
    and to  acquire and operate  all of PSNH's  power facilities.
    See In re Public Service Co. of New Hampshire, 
    963 F.2d 469
    ,
    470 (1st Cir.), cert.  denied, Rochman v. Northeast Utilities
    Service Co., 
    113 S. Ct. 304
     (1992).
    NU's proposal contained a two-step process:  first,
    PSNH would  emerge from  bankruptcy as a  stand-alone company
    bound  to a merger agreement  with NU; second,  PSNH would be
    merged  with   an  NU  subsidiary  created   solely  for  the
    acquisition (NU Acquisition Corporation), with  PSNH emerging
    as  the surviving entity.  After  the merger, PSNH would be a
    wholly-owned  subsidiary   of  NU  and  would   transfer  its
    ownership  interest   in  Seabrook  to  a   newly  formed  NU
    subsidiary,   North   Atlantic  Energy   Corporation  ("North
    Atlantic").    The second  step  would occur  only  after all
    necessary  approvals   were   received  from   the   relevant
    regulatory agencies.
    C.   Procedural History.
    On January 8, 1990, NUSCO, on behalf of NU and NU's
    operating subsidiaries, filed an  application with FERC under
    section 203 of  the Federal  Power Act ("FPA"),  16 U.S.C.
    824b (1988), seeking authorization for PSNH to dispose of all
    of its  jurisdictional facilities and  concurrently to  merge
    with, and become  a subsidiary  of, NU.   In connection  with
    -9-
    this application,  NUSCO filed four rate  schedules with FERC
    pursuant  to     205   of  the  FPA:    the   Seabrook  Power
    Contract,28   the  Sharing   Agreement29  and   two  Capacity
    Interchange Agreements.30
    The  Commission  consolidated consideration  of the
    merger  application and  rate  schedules,  accepted the  rate
    schedules for  filing and suspended their  effectiveness, and
    set for  hearings before an administrative  law judge ("ALJ")
    the questions  of whether the  Commission should grant  the
    203  application  and  approve   the  rate  schedules.    See
    Northeast Utilities Service Co.,  50 F.E.R.C.   61,266, reh'g
    granted  in part  and denied  in part,  51 F.E.R.C.    61,177
    (1990).  In its order, the Commission directed the parties to
    28  The Seabrook  Power Contract is a  life-of-the-unit power
    sales agreement between PSNH  and North Atlantic entered into
    concurrently with  NU's acquisition of PSNH  and the transfer
    of PSNH's share  of Seabrook  to North Atlantic.   Under  the
    contract, PSNH  agreed  to purchase  North Atlantic's  entire
    share of Seabrook capacity and  energy, according to a  cost-
    of-service formula rate.  The contract was intended to ensure
    that  North Atlantic would recover all of its costs from PSNH
    regardless of whether or not Seabrook actually operated.
    29   The Sharing Agreement allocates the benefits and obliga-
    tions from the  integrated operation of PSNH and  the current
    NU  system, as well as  the joint planning  and operations of
    these  systems.   This  agreement established  a formula  for
    sharing the  expected post-merger benefits that  would accrue
    to NU and PSNH  operating companies as a result  of operating
    efficiencies  and  the  ability  to take  single  participant
    status under the NEPOOL agreement.
    30    The two Capacity Interchange Agreements provide for the
    sale  and purchase  of  energy between  PSNH and  Connecticut
    Light & Power Company (CL&P) over a ten-year term.

    if  so,  what specific  conditions  should be  imposed."   50
    F.E.R.C. at 61,834-35.
    On December  20, 1990,  the ALJ issued  its Initial
    Decision  approving  the     203  application  and  the  rate
    schedules   with   certain   modifications  and   conditions.

    schedules.   Northeast Utilities  Service Co., 56  F.E.R.C.

    additional  filings  by  the  parties and  oral  argument  on
    transmission  pricing issues,  the Commission  issued Opinion

    application  and rate schedules.  Northeast Utilities Service

    Litigation  consolidated these petitions  for review  in this
    court, where  further petitions for  review were  filed.   28

    III. DISCUSSION.
    A.   Conditional Approval of the Merger.
    1.   Background.
    In reaching  his  decision to  approve the  NU-PSNH
    merger,  the   ALJ  found  that  the   merger  would  produce
    significant benefits.  Specifically, he found that:  (1) PSNH
    would emerge from bankruptcy  as a viable utility on  a solid
    financial  footing,  53  F.E.R.C.  at  65,211;  (2)  improved
    management techniques and economies of scale would reduce the
    operating costs  of Seabrook by  some $527 million,31  id. at
    65,212; (3) application of NU operating procedures  to PSNH's
    fossil steam plants would save  $100 million, id. at  65,213;
    (4) reductions in  administrative and general  expenses would
    save  $124  million, id.;  (5) NU's  record of  buying lower-
    priced coal on the  spot market would save $39  million, id.;
    and (6) the merger would yield $360 million in savings for NU
    because of  its ability to elect  "single participant status"
    31    This,  and all  other  dollar amounts  are net  present
    values unless otherwise noted.
    -13-
    in  the  New  England  Power  Pool  (NEPOOL),  a  power  pool
    comprised of most of the utilities in New England.  Id.
    The ALJ  also found that  unless several conditions
    were  imposed, the  merger  would have  short- and  long-term
    anticompetitive consequences because of the  merged company's
    increased market  power over  key transmission  facilities in
    both  the New England region and the Rhode Island and Eastern
    Massachusetts submarket ("Eastern  REMVEC").  53 F.E.R.C.  at
    65,214-19.   Under the  authority of   203(b)  of the FPA, 16
    U.S.C.    824b(b), the  ALJ  approved the  merger subject  to
    several conditions, including the  following:  (1) the merged
    company  must  offer  firm  (non-interruptible)  transmission
    service  for a minimum of 30 days  and a maximum of 20 years,
    53  F.E.R.C.  at  65,220-21;  (2) non-firm  service  must  be
    offered  for a one-day minimum  term, id. at  65,220; (3) the
    merger would be consummated concurrently with the filing of a
    compliance tariff which fully reflects  all of the terms  and
    conditions set  out in  the ALJ's  Initial  Decision, id.  at
    65,221;  (4) NU  must  implement its  New Hampshire  Corridor
    Proposal,32 thereby  making available 400 MW  of transmission
    32   The New Hampshire  Corridor Transmission Proposal allows
    New  England  utilities  to purchase  long-term  transmission
    rights from NU-PSNH in order to connect with power sources in
    northern New England and Canada.  See 53 F.E.R.C. at 65,225.
    -14-
    capacity  for wheeling33  by utilities  in both  northern and
    southern New  England, id.  at 65,225-27; and  (5) the merged
    company's veto  power on NEPOOL's  Management Committee would
    be restricted for the ninety day period immediately following
    consummation of the merger, id. at 65,230-31.
    In  Opinion No.  364, the  Commission affirmed  the
    ALJ's finding  that the merger, with  appropriate conditions,
    was consistent  with  the public  interest.   56 F.E.R.C.  at
    62,011.  It held,  however, that the $364 million  cost-shift
    between NU-PSNH and other NEPOOL members should not have been
    counted  as a benefit of the merger because it simply shifted
    costs dollar-for-dollar  among the membership without any net
    savings.34    56 F.E.R.C.  at  61,997.   The  Commission also
    held  that,  in evaluating  the  costs  and benefits  of  the
    merger, the ALJ  correctly attributed the benefits  resulting
    from  the merger to the  merger even if  those benefits could
    have been  achieved  by other  means.35   Id.  at  61,994-96.
    This conclusion  was reiterated  on rehearing in  Opinion No.
    364-A.  58 F.E.R.C. at 61,186-87.

    Petitioners  and intervenors argue that FERC erred,
    as  a matter  of law,  in holding  that  the benefits  of the
    merger outweighed its costs.
    -16-
    2.   The Statutory Standard.
    FERC's   authority   to    consider   the    merger
    applications of utilities  is set  forth in    203(a) of  the
    FPA, 16  U.S.C.   824b(a):  the Commission  "shall approve" a
    proposed merger of utility facilities if, "[a]fter notice and
    opportunity  for hearing, . . . the Commission finds that the
    proposed disposition, consolidation, acquisition,  or control
    will  be  consistent with  the public  interest."   
    Id.
       The
    Commission has the additional authority to grant approval for
    such transactions "upon such terms and conditions as it finds
    necessary   or  appropriate  to  secure  the  maintenance  of
    adequate service and the  coordination in the public interest
    of facilities subject to the jurisdiction of the Commission."
    16 U.S.C.     824b(b).    As the  Commission  noted  when  it
    reviewed the Initial Decision of the ALJ,
    [m]erger  applicants need not show that a
    positive  benefit  will  result   from  a
    proposed  merger.    The  applicant  must
    fully  disclose  all  material facts  and
    show  affirmatively  that  the merger  is
    consistent with the public interest.   It
    is  sufficient  if  the "probable  merger
    benefits  . . .  add up  to substantially
    more than the costs of the merger."
    56 F.E.R.C. at  61,994 (quoting  Utah Power &  Light Co.,  47
    F.E.R.C.  at  61,750  (1989)  (footnotes omitted);  see  also
    Pacific Power  & Light Co.  v. Federal Power  Commission, 
    111 F.2d 1014
    ,  1016 (9th  Cir. 1940).    We review  the record,
    therefore, to determine whether the Commission's finding that
    -17-
    the   probable   benefits   of   the  NU-PSNH   merger   were
    substantially  more   than   its  costs   was  supported   by
    substantial evidence.
    3.   Discussion.
    Petitioners make two claims  with regard to  FERC's
    evaluation  of the costs and benefits  of the NU-PSNH merger.
    First,  they  argue  that  the  Commission  should  not  have
    included resolution of PSNH's bankruptcy as a  benefit of the
    merger because:  (1) PSNH actually emerged from bankruptcy on
    May 16, 1991, the  effective date of the  Reorganization Plan
    ("RP");  and  (2) prior  to  gaining  the bankruptcy  court's
    approval  of the two-step RP, PSNH  had to show that it would
    be  financially  viable  as   a  stand-alone  entity  because
    regulatory approval  for the  second step  of the  RP (merger
    with and into NU) was not assured.  These two facts, however,
    do not  imply that  it was  error for  FERC  to consider  the
    "resolution of PSNH's bankruptcy" as  a benefit, indeed as  a
    principal benefit, of the merger.
    It  is  true  that  PSNH, as  a  technical  matter,
    "emerged" from  bankruptcy prior  to FERC's  consideration of
    the proposed merger.  The ALJ and the Commission did not hold
    otherwise.   The  ALJ  stated, and  the Commission  summarily
    affirmed the fact that "[t]he merger is part of  a plan which
    enables a  reorganized PSNH to  emerge from bankruptcy."   53
    F.E.R.C. at 65,211  (emphasis added); see also 56 F.E.R.C. at
    -18-
    61,993.  Like the state regulators  who approved the two-step
    merger  plan, the Commission  evaluated the plan  as a whole,
    anticipating  "the merger   not  `stand alone' PSNH    as the
    ultimate destiny  for the reorganized company."   53 F.E.R.C.
    at 65,211.   "All parties to  the reorganization contemplated
    [stand  alone]  status as  an interim  step  en route  to the
    merger."  
    Id.
       It was the entire  plan, which admittedly had
    two  sequential and  severable  steps, that  allowed PSNH  to
    emerge  from bankruptcy.  There is no evidence that the state
    regulators would have approved a plan to allow PSNH to emerge
    from bankruptcy  that included  only the first  "stand alone"
    step.  Indeed, there is evidence to the contrary.
    FERC  also found that "resolving" PSNH's bankruptcy
    meant  more  than  simply  the emergence  of  PSNH  from  the
    protection of  bankruptcy court.   FERC held  that the  final
    resolution of PSNH's bankruptcy included the treatment of its
    creditors and  stockholders who stood  to lose  approximately
    $250 million  in  the absence  of  the merger.    As the  ALJ
    observed, the Commission "regard[s] the right of these public
    bondholders as of primary importance after the consumers have
    been protected."  53 F.E.R.C. at 65,211 (quoting In re Evans,
    1 F.P.C. 511, 517  (1937) (approving an acquisition involving
    the reorganization  of a bankrupt utility)).   The Commission
    also held that it was  in the public interest to  approve the
    creation  of a  stronger, more  viable merged  entity, rather
    -19-
    than leaving PSNH in a "weakened", "stand alone" state.  This
    holding was sufficiently supported by evidence in the record.
    Petitioners also  claim that, given  the bankruptcy
    court's   "feasibility   finding"  required   by   11  U.S.C.
    1129(a)(11),36  the Commission  was estopped  from reaching
    the  conclusion that a "stand  alone" PSNH would  be "weak."
    We disagree.   The  bankruptcy court  and FERC evaluated  the
    merger proposal under  different standards.   The  bankruptcy
    court  was required  to determine  the likelihood  of further
    liquidation or reorganization proceedings were the plan to be
    approved.  FERC was obliged to determine whether the plan was
    "consistent  with   the  public   interest."    It   was  not
    inconsistent for FERC to find that although PSNH was  capable
    of  surviving  as  a stand  alone  entity,  it  would not  be
    "consistent  with the  public interest"  to prevent  a merger
    that  would  result   in  an  even  stronger  utility.    The
    principles of estoppel simply do not apply  in a case such as
    this, where the issues litigated and the standards applied in
    the two proceedings are so different.
    36   The Bankruptcy Code provides that:
    (a)   The   court   shall  confirm   a   plan   [of
    reorganization]  only  if   all  of  the  following
    requirements are met:
    (11) confirmation  of the plan is not  likely to be
    followed  by  the  liquidation,  or  the  need  for
    further financial reorganization, of the  debtor or
    any successor to the  debtor under the plan, unless
    such liquidation  or reorganization is  proposed in
    the plan.
    11 U.S.C.   1129(a)(11).
    -20-
    Even were petitioners correct in their asseveration
    that  FERC  improperly  counted  the  resolution   of  PSNH's
    bankruptcy  as a  benefit  of the  merger, "the  Commission's
    error would be immaterial in light of the overwhelming excess
    of other  benefits ($791  million) over  the costs  (0) still
    attributable . . . to the acquisition."   City of Holyoke Gas
    & Elec. Dep't v. S.E.C., 
    972 F.2d 358
    , 362 (D.C. Cir. 1992).
    Second,  petitioners  argue that  FERC  erred  as a
    matter  of law  in  weighing as  merger  benefits results  or
    alleged  savings   that  were,  or  could   be,  achieved  by
    "alternate  means."   Specifically, petitioners  contend that
    FERC's   failure  to   apply  the   "alternate   means"  test
    contradicted  general agency  policy  and  general  antitrust
    principles.
    It is undisputed  that utilities  are "not  immune"
    from antitrust laws.   Otter Tail Power Co. v. U.S., 
    410 U.S. 366
    ,  372-75 (1973); Town  of Concord  v. Boston  Edison, 
    915 F.2d 17
     (1st  Cir.  1990), cert.  denied,  
    111 S. Ct. 1337
    (1991).  At issue in this case is whether FERC is required by
    statute,  or otherwise,  to  engage  in "standard"  antitrust
    analysis before  passing on    203  merger applications.   In
    claiming that  FERC has such an  obligation, petitioners rely
    on a statute  governing agency approval of  bank mergers (the
    -21-
    "Bank  Merger  Act")  which   states  that  the  agency  with
    jurisdiction over a proposed bank merger,37
    shall not approve
    (A)  any  proposed merger  transaction
    which  would result  in  a  monopoly,  or
    which  would  be  in furtherance  of  any
    combination  or conspiracy  to monopolize
    or  to attempt to monopolize the business
    of  banking in  any  part  of the  United
    States, or
    (B)   any    other   proposed   merger
    transaction whose effect  in any  section
    of  the country  may be  substantially to
    lessen  competition, or to tend to create
    a monopoly, or which in any  other manner
    would be in restraint of trade, unless it
    finds that the anticompetitive effects of
    the  proposed   transaction  are  clearly
    outweighed in the public interest  by the
    probable  effects  of the  transaction in
    meeting the convenience  and needs of the
    community to be served. . . .
    (6)   The    responsible   agency   shall
    immediately  notify the  Attorney General
    of any  approval by  it pursuant  to this
    subsection    of   a    proposed   merger
    transaction.
    12 U.S.C.   1828(c)(5)-(6).   The Supreme Court, interpreting
    the Bank Merger Act, has held that before a bank merger which
    is  injurious to  the  public interest  may  be approved,  "a
    showing [must] be made that the gain expected from the merger
    cannot  reasonably be expected through other means."  U.S. v.

    Petitioners claim that the language of the Bank Merger Act is
    sufficiently similar to the statute governing FERC's approval

    entity  is  a national  bank, a  state  member bank,  a state
    nonmember bank, or a savings association.
    -22-
    of  proposed  mergers,  16  U.S.C.    824b(a),  because  both
    contain  a "public interest" standard, to require FERC to use
    the "alternate means" test which  bank regulators must use in
    evaluating proposed bank mergers.  We disagree.
    As with  any matter  of statutory construction,  we
    first examine the language  of the statute.  Under  16 U.S.C.
    824b(a),  the  Commission  is required,  after  notice  and
    opportunity  for hearing,  to  approve a  proposed merger  of
    utility  facilities if  it finds  that the proposal  "will be
    consistent  with  the  public interest."    That  is all  the
    statute  says.  There  is no explicit  reference to antitrust
    policies or principles.   There is no  evidence that Congress
    sought  to  have  the  Commission  serve  as  an  enforcer of
    antitrust  policy  in  conjunction  with  the  Department  of
    Justice and  the Federal Trade  Commission.  The  Bank Merger
    Act  reveals a  quite different  intention.   There, Congress
    explicitly  set out  standards for  approval of  bank mergers
    that incorporate  principles  embodied  in  the  Sherman  and
    Clayton  Acts.   12  U.S.C.   1828(c)(5).   By  requiring the
    reviewing  agency  to  notify  the Attorney  General  of  any
    decision  to approve  a  proposed bank  merger,  12 U.S.C.
    1828(c)(6),  Congress  expressed  its  desire  to  have  bank
    regulators  serve as pre-screening  bodies of  mergers which,
    because of their importance or character, in most  cases also
    deserve the attention of the Department of Justice.
    -23-
    The Bank  Merger Act  carries with it  the implicit
    presumption that  mergers are  to be disapproved  (the agency
    "shall not approve" a  bank merger "unless it finds  that the
    anticompetitive  effects are clearly outweighed in the public
    interest"  by   the  benefits   of  the  merger,   12  U.S.C.
    1828(c)(5)).   The  FPA,  on the  other hand,  requires the
    Commission to approve any merger that is "consistent with the
    public  interest."     16   U.S.C.     824b(a).     Antitrust
    considerations   are,   of   course,   relevant   in   FERC's
    consideration of  the "public interest"  in merger proposals.
    The  statute,  however,  does  not require  FERC  to  analyze
    proposed mergers under the same standards that the Department
    of Justice or bank regulators must apply.
    Although  the  Commission  must  include  antitrust
    considerations in its public interest calculus under the FPA,
    it is not  bound to use antitrust principles when they may be
    inconsistent  with the  Commission's  regulatory goals.   See
    Otter  Tail,   
    410 U.S. at 373
      ("[a]lthough   antitrust
    considerations  may be  relevant [in  determining  the public
    interest], they are not determinative").  In Town of Concord,
    this  court  observed  that indiscriminate  incorporation  of
    antitrust policy into utility regulation  "could undercut the
    very objectives  the antitrust  laws are designed  to serve."
    
    915 F.2d at 22
    .     Therefore,  "antitrust  analysis  must
    sensitively `recognize and  reflect the distinctive  economic
    -24-
    and  legal  setting' of  the regulated  industry to  which it
    applies."

    Regulated   "Monopolies":     The   Search  for   Substantive

    Petitioners  may  rest  assured that  were  FERC to
    approve  a merger of utilities which ran afoul of Sherman Act
    or other  antitrust policies, the utilities  would be subject
    to either prosecution by government officials responsible for
    policing the antitrust laws,  or to suit by private  citizens
    meeting the requirements  of standing.   See Otter Tail,

    B.   FERC's  Failure to Condition  Merger on NU's Waiver
    of Single Participant Status.
    Petitioners  argue  that  the  Commission  erred in
    failing to  condition the merger on waiver  by NU and PSNH of
    "single participant status" ("SPS")  in the New England Power
    Pool ("NEPOOL"), thereby preventing  the imposition of a $364
    million cost shift  from NU and PSNH to  the other members of
    NEPOOL.
    1.   Background.
    NEPOOL is  a power  pool comprised  of most  of the
    utilities in New England.  The association is governed by the
    New England  Power  Pool Agreement  ("the  Agreement")  which
    establishes a "comprehensive interconnection and coordination
    arrangement" among  its members in order  "to achieve greater
    -25-
    reliability and economies in the  production of electricity."
    Groton v.  FERC,  
    587 F.2d 1296
    ,  1298  (D.C.  Cir.  1978).
    Section  202(a)  of the  Federal  Power  Act encourages  such
    voluntary  interconnection  and  coordination of  electricity
    generating facilities in order to achieve economies of scale.
    16  U.S.C.    824a; see  also 16  U.S.C.    824a-1 (regarding
    pooling  agreements).  The Agreement  was approved as a filed
    rate  schedule  by  FERC's  predecessor,  the  Federal  Power
    Commission.   53 F.E.R.C. at  65,213.  Under  its terms, each
    member  is  required  to   supply  the  pool  with  resources
    ("Capacity Responsibility") according to a formula based upon
    the  relationship of the member's peak load to an estimate of
    aggregate peak load of all members.
    NU  experiences its  peak load  in the  summer, and
    PSNH experiences its peak load in the winter.  By aggregating
    these two,  complementary, peak loads, NU-PSNH  can achieve a
    lower Capacity Responsibility than would  be the case if  the
    two   utilities  remained  separate.    Because  the  overall
    capacity requirements of NEPOOL  will not change as  a result
    of the merger, the Capacity Responsibilities of other members
    must rise to  make up  for the savings  accruing to  NU-PSNH.
    The  ALJ  accepted  the  "undisputed" estimate  that  "single
    participant status" (SPS)  will result in a  shifting of some
    $360  million in costs from  NU-PSNH to other  members of the
    pool.

    2.   Discussion.
    Petitioners  offer six  arguments to  support their
    claim that FERC erred  in failing to condition the  merger on
    waiver of SPS by NU and PSNH.  First, petitioners  claim that
    the Commission  did not  properly interpret the  provision of
    the NEPOOL Agreement which  governs the election of SPS.   We
    agree with  the Commission's finding that  the Agreement both
    specifically allows for the election  by NU-PSNH of SPS,  and
    encourages  such elections.    Section 3.1  of the  Agreement
    provides in relevant part that:
    All  Entities which  are controlled  by a
    single person (such as a corporation or a
    common law business  trust) which owns at
    least seventy-five percent of  the voting
    shares   of   each  of   them   shall  be
    collectively   treated    as   a   single
    Participant   for    purposes   of   this
    Agreement, if they elect  such treatment.
    They are  encouraged to  do so.   Such an
    election shall  be  made by  signing  the
    appropriate   form  at   the  end   of  a
    counterpart of this Agreement.
    (Emphasis  supplied.)    Both  the  ALJ  and  the  Commission
    interpreted section 3.1 to be  an explicit endorsement of the
    election of  SPS by NU-PSNH.   The  ALJ stated that  "[i]t is
    undisputed  that  NU  and   PSNH  qualify  for  such  [single
    participant]  status under  the Agreement."   53  F.E.R.C. at
    65,213.  The Commission  gave great weight to the  unrebutted
    testimony  of  witness  Bigelow,   who  participated  in  the
    negotiation of  the NEPOOL Agreement regarding  the intent of
    the  original  signatories   to  the   Agreement  and   their
    -28-
    recognition  of  such  potentially  large  cost-shifts  among
    NEPOOL members.  Bigelow stated:
    [W]hen  we put  NEPOOL together  20 years
    ago,  we  recognized  that  these  things
    might happen.  This is not something that
    snuck  up  on people. . . .   And  we did
    discuss  at  length  what   would  happen
    because . . . we were then coming up to a
    potential   merger   of  Boston   Edison,
    Eastern Utilities, New England Power.  It
    was recognized that these kinds of things
    could happen in the future and we spelled
    out the ground rules and  recognized that
    that would  happen when it happened.  And
    the  people   who  didn't  like   it  got
    something else for it.
    53  F.E.R.C.  at 65,214.   Both  the  ALJ and  the Commission
    rejected petitioners' claim on the basis of both the language
    of the Agreement, and Bigelow's unrebutted testimony that not
    only  had the  signatories been  aware of such  a potentially
    large  savings  shift, but  that  those  utilities that  were
    dissatisfied  with this risk  received additional concessions
    as  compensation.    We  will not  disturb  the  Commission's
    findings.
    Second,  petitioners claim  that the  Agreement, as
    interpreted in  NEPOOL Power Pool Agreement,  56 F.P.C. 1562,
    1580 (1976), aff'd sub nom. Municipalities of Groton v. FERC,
    
    587 F.2d 1296
     (D.C. Cir. 1978), prohibits utilities with peak
    loads  in different  seasons  from  electing  SPS.    As  the
    Commission  explained,  this  argument  mischaracterizes  the
    Agreement and  the decision  of the Federal  Power Commission
    ("FPC") in NEPOOL.
    -29-
    The NEPOOL Agreement, as  initially filed
    and    as   approved,    allowed   single
    participant    status    for    utilities
    controlled by a single "person" owning at
    least 75 percent of the voting shares  of
    each utility.  An exception was expressly
    allowed  in the  filed agreement  for any
    Vermont  utility  which  elected   to  be
    grouped   with  Vermont   Electric  Power
    Company.  This exception was approved for
    essentially two reasons:  (1) the Vermont
    utilities  had  long  acted  as  a single
    contiguous  integrated  electric  entity;
    and (2) since  they all experienced their
    peak loads in winter,  single participant
    status would not give them a lower NEPOOL
    Capability Responsibility (and consequent
    savings).    A   broader  exception   was
    denied, however, for a group of municipal
    utilities (represented by MMWEC) that was
    not entitled to single participant status
    and  that lacked the two cited attributes
    of the  Vermont utilities.  The basis for
    the denial was that allowing  such status
    for "any group of systems, such as MMWEC,
    could   well   be   detrimental  to   the
    functioning of NEPOOL."
    The  NEPOOL  decision, thus,  does not
    stand  for  the  proposition that  single
    participant status is  available only  to
    utilities  having their peak loads in the
    same  season.    Instead,   another  way,
    indeed   the   primary   way,  in   which
    utilities  may qualify  is  if  they  are
    controlled  by  a  single person  with  a
    least 75-percent common ownership.   That
    is the basis upon  which NU and PSNH will
    presumably seek to  qualify if the merger
    is  approved.   Such status  is expressly
    allowed   under   the  NEPOOL   Agreement
    regardless of when NU and PSNH experience
    their peak loads.
    56 F.E.R.C. at 61,996-97.  The reasons  offered by the FPC in
    its  decision  to  grant  a  special  exception  for  Vermont
    utilities seeking SPS were  not intended to be, and  are not,
    conditions, in  addition to those  set out in  the Agreement,
    -30-
    which must be satisfied to elect SPS.  The FPC did not narrow
    the scope of Section  3.1 to apply only to  utilities sharing
    the  same peak  load  season; rather,  it  created a  special
    exception to the  75 percent rule  to accommodate the  unique
    situation faced by Vermont utilities.
    Third, petitioners  claim that FERC failed  to give
    proper consideration  to Section  4.2 of the  Agreement, "the
    interests of  other  pool members,  and  the purpose  of  the
    Agreement as  a whole."  Essentially,  petitioners argue that
    allowing  NU-PSNH  to  elect  SPS  would  violate  a  general
    provision  of the  Agreement, which states  that participants
    "shall  not . . . take  advantage of  the provisions  of this
    Agreement so  as to harm another Participant  or to prejudice
    the  position  of any  Participant  in  the electric  utility
    business."   We  reject  this argument  for the  same reasons
    expressed   by  the  Commission   in  its   decision  denying
    petitioners' request for a rehearing:
    [W]e  find more  relevance in  the NEPOOL
    Agreement's   explicit   endorsement   of
    single  participant  status  than in  the
    agreement's  general  goal of  "equitable
    sharing"   and  prohibition   on  members
    "taking  advantage"  of the  agreement to
    harm  or prejudice  other  members.   The
    NEPOOL Agreement  specifically encourages
    eligible    parties   to    seek   single
    participant status;  the provisions cited
    by  the  intervenors  are   general,  not
    specific.      Construing   the   general
    consistent  with  the  specific, we  find
    single participant status for  the merged
    company  consistent   with  an  equitable
    sharing,  as  envisioned  by  the  NEPOOL
    -31-
    Agreement, and not  violative of the  ban
    on  taking  advantage of  the agreement's
    provisions  to  harm  or prejudice  other
    members.
    58 F.E.R.C. at 61,189.   We agree with FERC's  interpretation
    of  the  Agreement.     The  NEPOOL  signatories   explicitly
    encouraged  qualified  members  to  seek  SPS,   indeed  they
    contemplated that members that merged might choose to do just
    that.   We agree  with the  Commission's construction  of the
    Agreement which avoids a direct conflict between Sections 3.1
    and 4.2, and instead gives both provisions reasonable effect.
    Fourth, petitioners argue that failure to condition
    the   merger  on   waiver  of   SPS  would   create  "serious
    disincentives"   for  current   members  to   continue  their
    membership  in NEPOOL,  and  that the  breakup  of NEPOOL  is
    contrary to the public interest.  Petitioners imply that FERC
    did not take seriously their complaints about SPS, but rather
    rested its decision  not to  require a waiver  solely on  the
    fact that the Agreement allowed the election of SPS.  This is
    simply not so.
    The  Commission reversed  the ALJ  on the  issue of
    whether SPS savings  should be  counted as a  benefit of  the
    merger.   The Commission  found that  because the  cost shift
    amounted  to  a  zero-sum   transaction,  with  NU  and  PSNH
    benefitting and the other members burdened dollar-for-dollar,
    the shift could not  be counted as a  benefit of the  merger.
    -32-
    56  F.E.R.C. at 61,997.  Thus, the Commission did not dismiss
    petitioners' claims regarding SPS without thought.
    Also,  the ALJ  found,  and the  Commission agreed,
    that SPS was essential to the merger, and that the merger, as
    conditioned, was in the public interest.  FERC must approve a
    proposed merger if it is consistent with the public interest.
    16  U.S.C.    824b(a).    FERC  has  the  discretion  to  add
    conditions  to a proposed  merger to  ensure that  the merger
    will, taken as a whole, be in the public interest.  16 U.S.C.
    824b(b).    FERC  need  not, however,  explain  why  every
    condition, or failure to  establish a condition is consistent
    with the public interest when considered separately and apart
    from the entire transaction.  Petitioners seem to argue  that
    FERC was required by law to  state why it was consistent with
    the  public interest  to  follow the  explicit  terms of  the
    approved fifteen  year-old  NEPOOL Agreement  rather than  to
    condition  the  merger  on   waiver  of  a  membership  right
    established by the Agreement.   FERC had no such  obligation.
    It need not have  explained why it failed to add a particular
    condition  prior to approving  a merger.   The statute simply
    provides that "[t]he Commission may grant any application for
    an order under this section in whole or in part and upon such
    terms and conditions as it  finds necessary or appropriate to
    secure the  maintenance of adequate  service and coordination
    in  the   public  interest  of  facilities   subject  to  the
    -33-
    jurisdiction  of the Commission."   16 U.S.C.    824b(b).  In
    this  case, the Commission  set forth a  reasonable basis for
    approving the  merger as consistent with  the public interest
    in light of the supplementary conditions the Commission found
    necessary.   FERC  need not  have gone  further than  this to
    explain  why it  failed  to place  further conditions  on the
    merger.
    Fifth,   petitioners   allege   that   FERC   acted
    inconsistently in  its  treatment of  the NEPOOL  Agreement's
    provisions regarding  voting rights and SPS.   The Commission
    adopted  a  condition limiting  the  merged company's  NEPOOL
    voting  rights to  prevent PSNH  and NU  from gaining  a veto
    power  in NEPOOL.  56  F.E.R.C. at 62,043-45.   FERC reasoned
    that,  while   there  was   evidence  that   the  signatories
    anticipated  that  large   cost-shifts  would  accompany  the
    election  of SPS in merger  situations, there was no evidence
    that they anticipated the  voting rights implications of such
    mergers.   58 F.E.R.C.  at 61,189.   It was not,  contrary to
    petitioners' argument,  inconsistent as a matter  of logic to
    condition voting rights where the Agreement was silent on the
    need or lack of need to do so, while failing to condition SPS
    where the  Agreement explicitly favored the  election of SPS.
    Furthermore, it was not  an error of law to  condition voting
    rights while  leaving SPS  rights untouched.   Petitioners do
    not  contest the Commission's decision to condition NU-PSNH's
    -34-
    voting  rights.    We  will uphold  whatever  conditions  the
    Commission  imposes on  a proposed  merger  so long  as their
    necessity is supported in the record by substantial evidence.
    Finally,  petitioners  contend that  the Commission
    "failed to  explain why  burdening other NEPOOL  members with
    $364 million in additional  costs with no offsetting benefits
    to them is consistent  with the public interest."   In making
    this argument, petitioners imply that each and every piece of
    a complex package of merger agreements and conditions must be
    able to  withstand "public interest"  analysis without regard
    to other pieces of the package or to other conditions imposed
    by  the  Commission.   Petitioners  also  imply that  if  any
    individual or group is harmed by a piece of the package, that
    provision is not in the public interest and must therefore be
    stricken  or modified.   Both  implicit arguments  are deeply
    flawed.
    In  evaluating a  transaction  such as  the one  at
    issue  here, the  Commission  is required  to  find that  the
    entire transaction, taken as a whole,  is consistent with the
    public interest.  16 U.S.C.    824b(a).  Each element of  the
    transaction  need not  benefit  every  utility or  individual
    which might  be affected; rather, the  whole transaction must
    be consistent with the interest of "the public."  There is no
    reason  to  think  that  the interest  of  individual  NEPOOL
    members is  synonymous with  the "public"  interest.  As  has
    -35-
    already been noted,  FERC may  add conditions  to a  proposed
    merger before granting approval.   16 U.S.C.   824b(b).   The
    statute  does  not  require,  however,  that  FERC  establish
    conditions so  that every effect of an  approved merger could
    withstand the "public interest" test.
    At  a less  theoretical level,  the ALJ  determined
    that the NEPOOL savings  "were a vital  part of the long  and
    strenuous negotiations which culminated in the resulting PSNH
    reorganization plan,"  and  the particular  savings  of  $146
    million   for  New   Hampshire   consumers  were   relied  on
    specifically by the  State of New Hampshire in  approving the
    merged company's rate package.   53 F.E.R.C. at 65,213.   The
    Commission accepted this  finding of the  ALJ, while, at  the
    same time, it reversed  the ALJ's decision to count  the $360
    million as  a benefit of the merger.   58 F.E.R.C. at 61,997.
    The fact that  the cost-shift was not a benefit to be counted
    in weighing the  benefits and  costs of the  merger does  not
    mean that  the election of SPS and the concomitant cost-shift
    is not in  the public interest.   Election of  SPS is in  the
    public interest because it is a central element of the merger
    plan  which, viewed  as  a whole,  was  found by  FERC  to be
    consistent  with  the public  interest  based  on substantial
    evidence in the record.  We approve the Commission's decision
    not to condition the merger on waiver by NU of SPS.
    C.   Timing of Merger's Consummation.
    -36-
    In  the  proceedings before  the  ALJ,  NU proposed
    filing  a transmission  tariff within  60 days  following the
    merger.  Intervenors and Commission staff proposed the filing
    and  approval of  an  interim  transmission  rate.   The  ALJ
    rejected  both proposals  and  instead held  that the  merger
    would  be  consummated upon  the  filing  of NU's  compliance
    tariff.  He reasoned as follows:
    I see no  need for  requiring one  tariff
    (with potential for controversy, charges,
    collections and refunds)  to be  followed
    by  yet  another  tariff,  with  its  own
    potential for still other disputes.
    Avoiding  a  transitional period  will
    make   it   unnecessary   to  require   a
    transitional  tariff.    To achieve  this
    result, consummation of  the merger  must
    be conditioned on  the concurrent  filing
    of  a  compliance   tariff  which   fully
    reflects all of  the terms and conditions
    set out in this Initial Decision.  Such a
    condition should encourage  a prompt  and
    fair compliance filing  because NU  could
    not begin  to  reap the  merger  benefits
    without it.
    53 F.E.R.C. at 65,221.  The Commission concurred:
    We    believe    the   GTC    [General
    Transmission   Conditions]  and   the  NH
    Corridor  Proposal,  as modified  herein,
    adequately    mitigate    the    merger's
    anticompetitive effects without requiring
    the adoption of the Merger Tariff.  Trial
    Staff stated that the Merger Tariff would
    make  service available  immediately upon
    approval of the merger.   We believe that
    the presiding judge accomplished the same
    result  by  allowing consummation  of the
    merger  when  NU  submits its  compliance
    filing.
    We further believe  that delaying  the
    merger's    consummation    until     the
    Commission   accepts    NU's   compliance
    -37-
    submittal    for    filing    would    be
    inappropriate   given   the   uncertainty
    surrounding    issues   which    may   be
    challenged   and   subject   to   further
    litigation  in the  compliance proceeding
    and  given our  commitment to  act before
    the Merger Agreement's December  31, 1991
    termination date.  We believe that NU and
    PSNH are  entitled to  a prompt and  fair
    resolution  of this  proceeding.   At the
    same time the intervenors are entitled to
    have service begin as soon  as practical,
    together  with a  fair resolution  of any
    disputes raised regarding NU's compliance
    filing.  Accordingly, we believe  that it
    is in the best  interests of all  parties
    to allow NU to consummate the merger when
    it submits  its  compliance filing.    We
    shall also require  NU to begin  honoring
    such  requests  for transmission  service
    under the  GTC,  as modified  herein,  at
    that  time.    Such transmission  service
    will be  provided at  either the firm  or
    non-firm  transmission rates  proposed in
    NU's   compliance   filing,  subject   to
    refund, and  without a refund  floor.  In
    reviewing    NU's   filing    to   ensure
    compliance  with  this  Opinion, we  will
    hold  NU to a very high  standard.  As NU
    itself  states, "[i]f NU  fails to comply
    with  the  letter   or  spirit  of   such
    [Commission]  requirement,  NU  would  be
    subject to summary judgment  with respect
    to any aspect of its compliance filing."
    56 F.E.R.C. at 62,025.
    Petitioners'  stated concern  is that,  by allowing
    the  merger to be consummated prior to FERC's approval of the
    compliance tariff, FERC did not provide a sufficient guaranty
    that NU would provide transmission access that would mitigate
    -38-
    the  merger's  anticompetitive  effects.38    Petitioners  do
    not, however,  seek  to unravel  the  merger.   Rather,  they
    propose that any  cost shift under the  NEPOOL Agreement, see
    discussion in  Part III(B),  supra, be postponed  until after
    the compliance tariff is approved.  Petitioners complain that
    the course chosen by FERC creates an incentive on the part of
    NU  to delay  proceedings on  the compliance  tariff, thereby
    maximizing  competitive  advantage.   Petitioners do  not, of
    course,  point  out  that  their  proposal  would  create  an
    incentive  on  their  part to  delay  final  approval of  the
    compliance tariff, thereby postponing the day when the NEPOOL
    cost shift will take effect.
    The ALJ and the Commission carefully considered the
    alternatives before reaching their decisions.  The Commission
    held that the anticompetitive effects of the merger  would be
    adequately  mitigated  by  the  dual  requirements   that  NU
    immediately provide  transmission access upon  the filing  of
    its compliance  tariff, and  that any  fees  collected by  NU
    would be subject to  refund without a refund floor.   Because
    NU  accepted  these  merger conditions,  the  Commission  can
    enforce NU's  promise to pay  such refunds if  the Commission
    finds them to be appropriate.  See Distrigas of Massachusetts
    Corp. v.  FERC, 
    737 F.2d 1208
    , 1225 (1st  Cir. 1984).   
    FERC 38
       We  note that,  at oral  argument, petitioners  conceded
    that no one  had as  yet sought access  to NU's  transmission
    facilities.
    -39-
    explicitly  warned NU  that  "[i]n reviewing  NU's filing  to
    ensure compliance with  this Opinion,  we will hold  NU to  a
    very high standard."  56 F.E.R.C. at 62,025.
    The Commission balanced the merging companies' need
    for a "prompt  and fair resolution" of  the merger proceeding
    against the intervenors' need "to have [transmission] service
    begin  as soon as practical,  together with a fair resolution
    of any disputes raised  regarding NU's compliance filing." 56
    F.E.R.C.  at 62,025.    An  agency's  discretion  is  at  its
    "zenith" when  it fashions remedies to  effectuate the charge
    entrusted to it by Congress.   Niagra Power Corp. v. FPC, 
    379 F.2d 153
    ,  159 (D.C. Cir.  1967).  See also,  Consolo v. FMC,
    
    383 U.S. 607
    , 620-21  (1966); Environmental Action,  Inc. v.
    FERC, 
    939 F.2d 1057
    , 1064 (D.C. Cir. 1991); Boston Edison Co.
    v. FERC,  
    856 F.2d 361
    ,  371 (1st Cir.  1988).  We  hold that
    FERC's exercise  of its  discretion was not  inappropriate in
    these  circumstances.   FERC  did not  defer, as  petitioners
    suggest,  consideration of the anticompetitive effects of the
    merger  which  FERC  itself   identified.    The   Commission
    recognized the effects, and dealt with them in a reasoned way
    which  balanced  the  competing  interests  of  all  parties.
    FERC's remedy  is not  unreasonable, and we  therefore affirm
    its order.
    D.   Protection of Native Load Customers.
    1.   Priority of Services.
    -40-
    a.   Background.
    In its  merger  application, NU  made  a  voluntary
    commitment   to   provide  wholesale   transmission  service,
    including third  party wheeling  service,39  for any  utility
    over  its existing transmission system.  At the same time, NU
    sought  to limit  this  obligation by  reserving an  absolute
    priority  for  power  purchases  on  behalf  of  native  load
    customers (whose  power  needs NU  is bound  by franchise  or
    contract  to  meet).   The  ALJ  held  that  although NU  may
    reasonably give  native load service  priority over  wheeling
    service if NU's transmission system had insufficient capacity
    to serve both, 53  F.E.R.C. at 65,221-222, NU could  not deny
    firm  wheeling   requests  based  upon  the   reservation  of
    transmission  capacity for  its  own non-firm  sales, id.  at
    65,225.
    In Opinion  No.  364, the  Commission balanced  the
    interests of  native load customers and  third party wheeling
    customers  and  affirmed  the  ALJ's denial  of  an  absolute
    priority:
    we  .  . .  deny  NU's  proposal to  give
    higher priority to  its own non-firm  use
    than  to third  party  requests for  firm
    wheeling    in     allocating    existing
    transmission  capacity.    In  no  event,
    however, will  NU be required  to provide
    firm third party wheeling service  out of
    existing   transmission   facilities   if
    39   For a definition of "wheeling" see n.9, supra.
    -41-
    reliability  of  service  to native  load
    customers would be adversely affected.
    56  F.E.R.C. at  62,021 (footnote  omitted).   The Commission
    found it "reasonable to allow NU to reserve firm transmission
    capacity  to  provide reliable  service  to  its native  load
    customers."  Id. (Emphasis in original.)
    On rehearing,  NU asked the  Commission to  clarify
    the  scope of  the "reliability"  criterion.   The Commission
    "reiterate[d] that under no circumstances will NU be required
    to provide firm wheeling service out of existing transmission
    capacity where  doing so would impair  or degrade reliability
    of  service to native load customers."  58 F.E.R.C. at 61,199
    (emphasis  removed).   The  Commission  held  the concept  of
    reliability generally  encompasses the:   (1) reservation  of
    transmission capacity to back  up large generating units; (2)
    provision of generation reserves; and (3) coverage of certain
    future  needs.     As  to  the  coverage   of  future  demand
    requirements, the Commission  specifically ordered that  "any
    capacity needed for reliability purposes  within a reasonable
    planning horizon  must be offered  for wheeling use  until NU
    expects  to need the capacity  for reliability reasons."  Id.
    at 61,199-200.
    Petitioners assert  that the  decision to accord  a
    priority to native load  over transmission load is arbitrary,
    discriminatory, and  anticompetitive.   They argue  that FERC
    neither  defined  nor  justified  the   priority  granted  by
    -42-
    allowing reservation of transmission capacity for native load
    service  and  that  any  such  priority  creates  competitive
    advantages for  NU.  We  hold that the  Commission adequately
    defined and reasonably justified its decision to allow such a
    reservation  and  properly   addressed  the   anticompetitive
    concerns raised by the intervenors.
    b.   Discussion.
    Although the Commission reaffirmed the general rule
    that  firm transmission service  should be  accorded priority
    over  non-firm  service, even  if  the  latter would  benefit
    native load,    it nonetheless  allowed  NU to  reserve  firm
    transmission capacity  needed to ensure reliability of native
    load  service and allowed the  use of this  capacity for non-
    firm transactions.  58 F.E.R.C. at 61,196.  Thus, native load
    service will receive  a "priority" over third-party  wheeling
    service  in  allocating existing  transmission  capacity when
    reliability  of service  to  native load  would be  adversely
    affected.     The  Commission  specifically   qualified  this
    priority by requiring NU  to offer the capacity  for wheeling
    use until NU needed  it to assure reliability to  native load
    customers.
    There  is nothing arbitrary or discriminatory about
    FERC's decision.  It struck  a reasonable balance between the
    competing interests of native load customers and  third-party
    wheeling customers.  NU-PSNH is obligated to serve its native
    -43-
    load  customers.  In return for this obligation to serve, the
    native load customers regularly bear the cost of transmission
    facilities;  native load  customers pay  for them,  use them,
    plan  on them, and rely on them.   As the ALJ noted, "[e]very
    New England utility favors  its own native load.   Nothing in
    the NEPOOL agreement requires  its members to surrender their
    native load preference, and none do."  53 F.E.R.C. at 65,222.
    Thus,  "NU should be allowed  to give priority  over safe and
    reliable service to its  native load customers using existing
    transmission capacity  built to  serve those customers."   58
    F.E.R.C. at  61,199.   FERC explicitly defined  and justified
    the challenged native load "priority."
    2.   Transmission Upgrades Pricing.
    a.   Background.
    NU's commitment to provide third-party transmission
    service   includes   the  obligation   to   build  additional
    transmission facilities as necessary to  relieve transmission
    constraints on  its system.   58  F.E.R.C.  at 61,204-10;  56
    F.E.R.C. at 62,021-24.   The issue  then becomes, how  should
    the  cost  of  constructing  such  transmission  upgrades  be
    allocated.  The ALJ stated  that questions of cost allocation
    are  best  addressed  in  future  proceedings  regarding  the
    particular   responsibilities   for  particular   facilities.
    Nevertheless,  the ALJ  adopted  the "but  for" analysis  for
    determining responsibility proposed by NU witness Schultheis:
    -44-
    [W]heeling customers must make a pro rata
    contribution   whenever  the   facilities
    would  not have been  needed but  for the
    wheeling  transfers across  a constrained
    interface.   This means that  NU's native
    load customers pay for the new facilities
    they  create  the need  for  and wheeling
    customers  pay  for  the facilities  they
    create the need for.
    53 F.E.R.C. at 65,223.  The ALJ also noted that the financial
    exposure of  transmission customers  was limited by  the cost
    caps  to  which NU  was committed.40    Id. at  65,224.   The
    Commission agreed that cost  questions should be litigated in
    the context of a specific proposal,  and accepted the concept
    of  the "but for" test  as a framework  for ascertaining cost
    responsibility and the  use of  the proposed cost  caps as  a
    reasonable  means of  limiting  the  transmission  customers'
    responsibility for  future upgrades.  56  F.E.R.C. at 62,028-
    030.   The Commission reaffirmed that  decision on rehearing.
    58 F.E.R.C. 61,204-207.
    Petitioners  contend that the  Commission failed to
    adequately  explain  the pricing  policy  it  will employ  in
    pricing  transmission upgrades.  Basically, petitioners claim
    the ruling is too ambiguous to determine whether, or how, the
    40  NU committed  to cap  cost responsibility  to "(1)  those
    specific facilities  identified  by NU  at  the time  of  the
    wheeling request as needing to be built or upgraded either at
    the time of the request or in the future; and (2) the maximum
    dollar  amount  contained  in  NU's  initial  estimate  of  a
    wheeling customer's pro  rata share  of the  costs of  future
    upgrades  needed  to  accommodate   a  request  for  wheeling
    service."
    56 F.E.R.C. at 62,031-32.
    -45-
    Commission changed its  policy from the traditional  "rolled-
    in" approach used  in pricing transmission service.   We hold
    that   the  Commission   provided   a  clear   and   reasoned
    justification for  the principles that will  guide its future
    determinations of  transmission upgrade  pricing.  We  affirm
    the Commission's decision not  to modify the basic principles
    adopted in its order.
    b.   Discussion.
    In accepting as reasonable  the "but for" test, the
    Commission  has  done no  more than  approve a  framework for
    determining  cost responsibility  which furthers  the general
    principle  that transmission  costs should  be born  by those
    entities  responsible  for the  cost.    58 F.E.R.C.  61,205.
    Under  this test,  incremental  cost pricing  could be  found
    appropriate when firm wheeling across  a particular interface
    would  degrade reliability absent  upgrades.   The Commission
    specifically declined, however, to answer the requests of the
    intervenors  to  decide  the "rolled-in  versus  incremental"
    rate41 issue in  the abstract and  chose instead to  evaluate
    it only within the  context of a particular rate  proposal or
    upgrade.  Id.   The Commission articulated  how it envisioned
    41  Under "rolled  in" pricing principles, the upgrade  costs
    would  be rolled in with  other company costs  and charged to
    all ratepayers as part of NU's  general rate structure; while
    administratively   simple,   it   ignores  any   concept   of
    responsibility.  Thus, incremental pricing principles look to
    hold parties responsible for their share of upgrade costs.
    -46-
    pricing  transmission  upgrades   and  adopted  a   condition
    limiting  the  amount  NU  may  propose  to  collect  from  a
    transmission customer to the greater of
    (1) the incremental  cost of new  network
    facilities  required  at  the   time  the
    customer's new transmission load is added
    or (2) the rolled-in cost of  all network
    facilities required to serve the combined
    transmission loads of [NU], including any
    required transmission additions.
    Id. at 61,206.   Thus, a wheeling customer may be charged the
    greater of rolled-in cost rates or incremental cost rates.
    The Commission acknowledged  that the  introduction
    of incremental  cost pricing  principles is a  departure from
    its  traditional pricing  policies42 and  justified  this new
    policy  on NU's  unprecedented  obligation  to provide  third
    party transmission service.   Id.  The  Commission noted that
    incremental  cost  pricing  may  be  appropriate  in  certain
    circumstances,  but  decided to  leave  the  details of  cost
    responsibility  questions to  a  future specific  section 205
    rate case.  When such a  case arises, NU will bear the burden
    of   justifying  "any   direct  assignments   of   costs  and
    support[ing] any arguments that  reliability is degraded by a
    particular  firm transmission  service.    No presumption  is
    42     The  Commission generally  has  adhered to  rolled  in
    pricing,   but  has   never  precluded   particularized  cost
    allocations to  specific  customers where  appropriate.   See
    Utah Power & Light Co., 45 F.E.R.C.   61,095, at 61,291 n.163
    (1988);  Public Service Co. of Indiana, 51 F.E.R.C.   61,367,
    at 62,203 (1990).
    -47-
    created  by  NU's  `but  for' criterion  that  firm  wheeling
    customers always cause the need for upgrades."  Id. at 61,207
    (quoting 56 F.E.R.C. at 62031).   The Commission also allowed
    that  any  reliance by  NU  upon the  "but  for" test  may be
    challenged in  future actions.   The Commission  sufficiently
    explained and  justified the  principles that will  guide its
    transmission upgrade pricing.
    E.   Opportunity Cost Pricing.
    As has already been discussed, the Commission found
    it necessary to impose a number of conditions on the proposed
    NU-PSNH merger to mitigate  the merged company's market power
    in the  markets for  transmission and short-term  bulk power.
    58 F.E.R.C.  at 61,195.    Specifically, the  Commission held
    that  NU  must  provide  firm  transmission  service  out  of
    existing  capacity  for  any   utility,  subject  only  to  a
    reservation  of  sufficient  capacity  to  maintain  reliable
    service to its  native load customers  and to honor  existing
    contractual obligations.   NU was  prohibited, however,  from
    denying a request for  firm transmission service by reserving
    capacity for  non-firm transactions  that would enable  it to
    provide more economical service to its native load customers.
    56 F.E.R.C.  at 62,014-21;  58 F.E.R.C. at 61,196-200.   FERC
    also  held   that  NU  must  build   additional  transmission
    facilities   as   needed   to   provide   transmission  where
    insufficient capacity  exists.  56 F.E.R.C.  at 62,021-24; 58
    -48-
    F.E.R.C. at 61,204-10.   The Commission found that  these and
    other conditions  would  "adequately mitigate"  the  merger's
    anticompetitive effects.  58 F.E.R.C. at 61,213.
    On rehearing, NU and  the States of Connecticut and
    New Hampshire  argued that the Commission  should address the
    issue of  firm transmission  pricing because, in  Opinion No.
    364, FERC  had established  principles governing  the related
    issue of  firm transmission priority which  made NU's ability
    to purchase  inexpensive power (which would lower its cost of
    serving  its  native  load  customers)  subordinate  to   its
    obligation  to provide  firm transmission for  third parties.
    58  F.E.R.C.  at  61,201-02.    The  Commission  agreed,  but
    declined  to approve  "opportunity  cost  pricing"43  outside
    the  context of  a specific  tariff proposal.   Instead,  the
    Commission announced three "basic  goals" to guide its future
    decisions on the  pricing of firm transmission service on the
    merged company's existing capacity, and left the door open to
    NU  to propose  a tariff  based on  opportunity costs  or any
    43   As the Commission explained, opportunity costs
    are the  revenues lost or  costs incurred
    by  a  utility  in providing  third-party
    transmission  service  when  transmission
    capacity is insufficient to  satisfy both
    a  third-party  wheeling request  and the
    utility's   own   use.     For   example,
    opportunity   costs  might   include  the
    revenues lost or costs incurred because a
    utility  must  reduce its  own off-system
    purchases or sales in order to overcome a
    constraint on the [transmission] grid.
    58 F.E.R.C. at 61,200-201.
    -49-
    other  methodology  that would  meet  the three  goals.   The
    Commission explained its decision as follows:
    We are now confronted with the need  to
    provide   NU   with  enough   specificity
    regarding  what it  will  be  allowed  to
    propose for the  pricing of future third-
    party  wheeling  service,  so   that  the
    company  can  decide  whether to  proceed
    with the  merger.  We also  cannot ignore
    the  need  to  act  as  expeditiously  as
    possible  given the  commercial realities
    and time pressures presented in corporate
    matters subject to our  jurisdiction, and
    in  particular  the  need  to  resolve  a
    bankruptcy situation.   At the  same time
    we are confronted with the need to ensure
    an  adequate record on pricing issues and
    to   afford   all  parties   an  adequate
    opportunity to voice their objections.
    Balancing  these  respective needs,  we
    conclude  that  the  best  course  is  to
    provide guidance on  pricing issues,  but
    to defer specific  pricing issues to  the
    compliance phase of  this proceeding,  or
    to subsequent cases where  the Commission
    may consider specific  proposals from  NU
    in a concrete, factual setting and with a
    more developed record.
    . . . .
    First, the  native load customers  of the
    utility  providing  transmission  service
    should   be   held  harmless.     Second,
    transmission customers  should be charged
    the lowest reasonable cost-based rate for
    third-party transmission service.  Third,
    the pricing should prevent the collection
    of  monopoly  rents  by the  transmission
    owner and  promote efficient transmission
    decisions.      In  ruling   on  specific
    proposed  rates,  we  will balance  these
    three  goals  in light  of the  facts and
    circumstances presented at that time.
    58 F.E.R.C. at 61,203 (emphasis added) (footnotes omitted).
    FERC  was careful  to  point out  that it  endorsed
    opportunity cost pricing  only insofar as NU  could show that
    -50-
    it could "propose rates which  include legitimate, verifiable
    opportunity costs."  Id.   The Commission warned NU  that any
    such  proposal would  be carefully  scrutinized and  would be
    subject to challenge.  Id. at 61,203-04.  Specifically,  FERC
    stated that  NU would  have to  address the  following issues
    should it seek recovery of opportunity costs:
    (1) whether opportunity  costs should  be
    capped by incremental expansion  costs or
    any  other  cap;   (2)  whether   current
    wheeling   and   wholesale   requirements
    customers  should be  treated differently
    from   future   wheeling  and   wholesale
    requirements    customers,    e.g.,    by
    receiving    "grandfather"   rights    to
    embedded cost  rates  for the  amount  of
    transmission  capacity they  already use;
    (3) how NU  will identify those customers
    responsible for growth on its  system and
    what   particular   new  facilities   are
    necessary to accommodate that growth; (4)
    whether  and how third  parties should be
    protected   from   uncertainty  regarding
    fluctuations  in  opportunity costs;  (5)
    how  the proposed rates  will prevent the
    collection of monopoly rents; and (6) how
    the  proposed  opportunity costs  will be
    verified.
    Id.    The Commission  expressly  postponed consideration  of
    whether opportunity cost pricing  would be inconsistent  with
    nondiscriminatory  pricing  and  nondiscriminatory terms  and
    conditions of  service until  those issues  were raised  in a
    concrete factual context.  Id. at 61,204, n.118.
    Petitioners claim that FERC's decision  amounted to
    an arbitrary endorsement of opportunity cost pricing that was
    not  supported  by evidence  in  the  record, was  inherently
    -51-
    discriminatory, and contrary to FERC's  regulation of natural
    gas pipelines.   Petitioners' underlying concern  seems to be
    that  when  the  issue arises  next  in  the  context of  the
    Commission's  review  of NU's  compliance  tariff, FERC  will
    simply approve the tariff and dismiss petitioners' objections
    on the  ground that  opportunity cost pricing  principles had
    already  been  endorsed  by  the  Commission.    Although  we
    understand petitioners' concerns,  we believe  that they  are
    misplaced and that FERC did not go as far as petitioners fear
    in endorsing opportunity cost pricing.
    Petitioners will have an opportunity to contest any
    compliance tariff proposed by NU.  The Commission itself laid
    out a number of issues which NU would have to address were it
    to  propose a tariff based on opportunity costs.  58 F.E.R.C.
    at 61,203.   Only  after carefully considering  the competing
    interests of providing  guidance to  NU as to  what kinds  of
    tariffs it would consider, and  the need to endorse  specific
    methodologies only on the  basis of a fully-developed record,
    did  the Commission  decide  to outline  broad pricing  goals
    which would allow  for a number of pricing  schemes including
    opportunity  cost pricing.  Id.   It was  squarely within the
    Commission's  power  to defer  consideration  of petitioners'
    assertions until  after NU filed  its compliance tariff.   As
    the  Supreme  Court  has  held,  "[a]n  agency  enjoys  broad
    discretion in determining how  to handle related yet discrete
    -52-
    issues  in  terms  of  procedures, and  priorities."    Mobil
    Exploration   &   Producing   Southeast,   Inc.   v.   United
    Distribution  Cos., 
    111 S. Ct. 615
    ,  627 (1991)  (citations
    omitted).   Petitioners argue that deferral was inappropriate
    in this case because  their objections went "to the  heart of
    the  public interest  determination  to be  made."   Maryland
    People's Counsel v. FERC, 
    761 F.2d 768
    , 778 (D.C. Cir. 1985).
    We disagree.
    The   Commission   announced   pricing  goals   and
    conditions  that   it  determined  would   keep  the   merger
    consistent  with the  public  interest, and  would result  in
    "just and  reasonable rates."   Until NU proposed  a specific
    tariff regime, the Commission did not have a developed record
    to evaluate on the  merits.  The Commission remains  free to,
    and  we expect it will, invite  objections to NU's compliance
    tariff from  affected parties,  and will reject  any proposed
    tariff that  conflicts with its  statutory responsibility  to
    approve rates  that are "just and reasonable," and to approve
    mergers that are, as conditioned, "consistent with the public
    interest."
    F.   Environmental Impact Statement.
    The  City of  Holyoke  Gas  &  Electric  Department
    ("HG&E") alleges that FERC's refusal to examine the potential
    environmental  impacts  of its  approval  of  the merger  was
    arbitrary and capricious.  We disagree.
    -53-
    The National Environmental  Policy Act of 1969,  42
    U.S.C.    4321 et seq., ("NEPA") requires federal agencies to
    consider the  potential environmental effects  of a  proposed
    major  federal  action  that  may  significantly  affect  the
    quality of the human environment.   Section 102(2)(C) of NEPA
    states:
    The Congress authorizes and directs that,
    to the  fullest extent  possible:  . .  .
    (2) all    agencies   of    the   Federal
    Government shall
    . . . .
    (C)  include  in every  recommendation or
    report on proposals  for legislation  and
    other major Federal actions significantly
    affecting  the  quality   of  the   human
    environment, a detailed statement  by the
    responsible official on
    (i)  the  environmental  impact of  the
    proposed action,
    (ii) any  adverse environmental effects
    which  cannot  be   avoided  should   the
    proposal be implemented,
    (iii)  alternatives   to  the  proposed
    action,
    (iv)  the  relationship  between  local
    short-term uses of man's  environment and
    the maintenance and enhancement  of long-
    term productivity, and
    (v) any  irreversible and irretrievable
    commitments of resources  which would  be
    involved in the proposed action should it
    be implemented.
    42  U.S.C.    4332(2)(C).   Agencies  were authorized,  under
    guidelines  promulgated  by  the  Council   on  Environmental
    Quality ("CEQ"), to create categorical exclusions for actions
    which do not individually  or cumulatively have a significant
    effect  on  the human  environment.    40  C.F.R.     1507.3,
    1508.4.    FERC  adopted   such  a  category  of  exclusions,
    -54-
    including one for merger  approvals such as the one  at issue
    in this case.  That regulation states in pertinent part:
    (a) General  rule.  Except  as stated  in
    paragraph (b) of this section, neither an
    environmental    assessment    nor     an
    environmental  impact  statement will  be
    prepared  for  the following  projects or
    actions:
    . . . .
    (16) Approval of actions under sections
    4(b), 203, 204, 301,  304, and 305 of the
    Federal  Power  Act relating  to issuance
    and  purchase of  securities, acquisition
    or   disposition  of   property,  merger,
    interlocking directorates, jurisdictional
    determinations and accounting orders.
    18  C.F.R.    380.4(a)(16).    An  agency  need  not issue  a
    "finding  of  no  significant  impact"  in  cases  concerning
    matters that fall into a categorical exclusion.  40 C.F.R.
    1501.3, 1501.4, 1508.13.
    CEQ  guidelines  also  required  agencies  adopting
    categorical   exclusions   to   "provide  for   extraordinary
    circumstances in which a normally  excluded action may have a
    significant environmental effect."  40 C.F.R.   1508.4.  FERC
    made such provision in its regulations:
    (b)    Exceptions     to    categorical
    exclusions. (1) In accordance with 40 CFR
    1508.4, the Commission and its staff will
    independently    evaluate   environmental
    information  supplied  in an  application
    and  in  comments by  the public.   Where
    circumstances indicate that an action may
    be a major  Federal action  significantly
    affecting  the  quality   of  the   human
    environment, the Commission:
    (i) May require an environmental report
    or    other    additional   environmental
    information, and
    -55-
    (ii)  Will   prepare  an  environmental
    assessment  or  an  environmental  impact
    statement.
    (2) Such circumstances  may exist  when
    the action  may have an effect  on one of
    the following:
    (i) Indian lands;
    (ii) Wilderness areas;
    (iii) Wild and scenic rivers;
    (iv) Wetlands;
    (v) Units of  the National Park System,
    National   Refuges,   or  National   Fish
    Hatcheries;
    (vi)  Anadromous   fish  or  endangered
    species; or
    (vii)  Where the  environmental effects
    are uncertain.
    However, the existence of  one or more of
    the above will not  automatically require
    the submission of an environmental report
    or  the  preparation of  an environmental
    assessment  or  an  environmental  impact
    statement.
    18  C.F.R.     380.4(b).44    HG&E  argues  that  the NU-PSNH
    merger might  "alter mixes  of generation  in New  England by
    constraining  the locations for new plants."   HG&E points to
    the language of 18 C.F.R.   380.4(b)(1)(ii) in support of its
    position  that FERC was  compelled, at the  least, to explain
    why  it   was  not  obliged   to  perform  the   analysis  of
    environmental  effects required  by  NEPA.   HG&E also  cites
    FERC's  decision  in  Southern   California  Edison  Co.,  49
    F.E.R.C.     61,091  (1989)   (holding  that    380.4(b)  was
    triggered when approved merger would result in the dumping of
    44  HG&E  does  not challenge  the  validity  of  any of  the
    applicable regulations cited above.
    -56-
    hundreds of tons of additional air contaminants into the most
    polluted air in the United States).
    There was no evidence in the record of identifiable
    environmental harms that would likely result from the NU-PSNH
    merger.  The  fact that new generating  facilities might wind
    up  in different locations than  would have been  the case in
    the absence of  the merger does not approach in significance,
    because  its  significance  is  not quantifiable,  the  known
    effects of  the  merger between  Southern  California  Edison
    Company  and San  Diego Gas  & Electric  Company.   Thus, the
    factual  situation presented in Southern California Edison is
    completely distinguishable from that of this case.
    The   character  and   location   of   the   future
    environmental effects of the  NU-PSNH merger are so uncertain
    that  no  meaningful  environmental  review would  have  been
    possible, even had  FERC made the effort.  Here, FERC was not
    approving  a  regional  development  plan.    It  was  merely
    approving a merger between utility companies, albeit a merger
    involving  two  of  the  largest utilities  in  New  England.
    Energy  demand may increase in New England over the following
    decades, and the fact  of the merger may influence  how those
    needs  are met.  Nevertheless, any attempt by FERC to prepare
    an  EIS would  have involved  little more  than spinning  out
    multiple  hypothetical  development forecasts,  with multiple
    options  for   the  type,  amount  and   location  of  future
    -57-
    generating facilities.  See  Kleppe v. Sierra Club,  
    427 U.S. 390
    , 401-2 (1976).  Once concrete plans have been established
    for   the   construction   of  transmission   or   generating
    facilities, those  proposals will  be reviewed under  NEPA or
    the applicable state environmental review procedures.
    FERC  was justified  in  deciding  that neither  an
    environmental   assessment   nor   an  environmental   impact
    statement was required prior to approving the NU-PSNH merger.
    G.   HG&E's "Unique" Harm.
    HG&E also  contends that because it  relied on PSNH
    New Hampshire  Corridor facilities for over  one-third of its
    electricity supply,  it would be "uniquely  threatened" by NU
    in head-to-head competition for  large, industrial loads.  To
    protect    itself,   HG&E   requested   that   FERC   either:
    (1) disapprove  the merger;  (2) require  the  divestiture or
    restructuring of  NU's retail  business in Holyoke  (HWP); or
    (3) grant  HG&E  grandfather  rights to  PSNH  New  Hampshire
    Corridor transmission.  The ALJ rejected the "drastic remedy"
    of divestiture of HWP, stating that it was  "wholly uncalled-
    for  by anything in this record," and holding that HG&E would
    be  adequately  protected by  the  conditions  to the  merger
    designed   to   address   the  anticompetitive   effects   on
    transmission dependent  utilities ("TDUs").   53  F.E.R.C. at
    65,232.
    As the ALJ described,
    -58-
    [t]he  Transmission  Dependent  Utilities
    (TDUs) are  "entirely dependent on  NU or
    PSNH  for  their bulk  power transmission
    needs."  These  companies (most of  which
    involve municipal ownership) are  not big
    enough  to  own  or construct  sufficient
    generation to meet their loads.  As their
    brief states, they "are physically unable
    to  engage in any  bulk power transaction
    without using the NU or PSNH transmission
    systems.  Absent  economic access to NU's
    or  PSNH's  transmission facilities,  the
    TDU  cannot  survive  as  an  independent
    entity."   The  TDUs compete with  NU and
    PSNH in the wholesale bulk  power market;
    each   TDU,   like  NU/PSNH,   seeks  out
    attractive sources of  supply.  TDUs thus
    "are in  the  uneasy position  of  having
    their    only    source   of    essential
    transmission  service  in  the  hands  of
    their principal competitor."  These small
    companies,    uniquely    vulnerable   to
    possible  anticompetitive   conduct,  are
    entitled  to  some measure  of protective
    assurance regarding NU/PSNH's post merger
    conduct.
    53  F.E.R.C. at 65,232-33.   The ALJ held  that "[a]ll rates,
    terms and  conditions of NU/PSNH transmission  service to the
    TDUs in effect  on this date shall . .  . be maintained after
    the merger,  unless and until changes are  either agreed upon
    by  the merged  company and  the TDUs,  or authorized  by the
    Commission."  53 F.E.R.C. at 65,233.  In short, while finding
    that  TDUs  were  "uniquely  vulnerable"  to  anticompetitive
    conduct by NU-PSNH,  the ALJ  found that HG&E  had not  shown
    that  it was  entitled to  protections beyond those  given to
    TDUs  generally.    The  Commission agreed,  56  F.E.R.C.  at
    62,049,  but bolstered the protection for TDUs ordered by the
    -59-
    ALJ by imposing the additional condition  that NU establish a
    special tariff for TDUs.  Id. at 62,050.
    HG&E  points  to  no  evidence  in  the  record  to
    indicate  that it  faced anticompetitive consequences  of the
    merger sufficiently  different in  character or magnitude  to
    warrant greater  protections than those given  to other TDUs.
    We therefore affirm the Commission's actions to protect TDUs,
    which were adequately explained and supported in the record.
    H.   Modifications to the Filed Rate Schedules.
    The Commission analyzed the Seabrook Power Contract
    and Capacity Interchange Agreements  filed by NUSCO under the
    "just and reasonable"  standard of    206 of  the FPA,45  and
    ordered the  following modifications to  the rate  schedules:
    (1) deletion of the automatically adjusting rate of return on
    equity  provision  in  the   Seabrook  Power  Contract;   (2)
    reduction of the  rate of  return on equity  in the  Seabrook
    Power  Contract from  13.75 percent  to 12.53  percent;46 (3)
    45   Section  206(a)  of  the  FPA,  16  U.S.C.     824(e)(a)
    provides:
    Whenever the  Commission, after hearing
    had  upon   its   own  motion   or   upon
    complaint, shall find that any rate . . .
    collected by any public  utility . . . is
    unjust,        unreasonable,       unduly
    discriminatory   or   preferential,   the
    Commission shall determine  the just  and
    reasonable  rate . . .  to be  thereafter
    observed and in force, and shall  fix the
    same by order.
    46   NUSCO did not appeal this modification.
    -60-
    North  Atlantic's decommissioning expenses under the Seabrook
    Power Contract  and any subsequent changes  thereto were made
    subject to  review by  the Commission;  (4) reduction  in the
    rate  of return  on  equity  specified  in the  two  Capacity
    Interchange Agreements  from 14.50  percent to 13.17  percent
    for the period from July 27, 1990 through August 8, 1991, and
    thereafter  to  12.93 percent;  and  (5)  the Seabrook  Power
    Contract  could be modified  by the Commission  in the future
    under the "just and reasonable" standard of   206 of the FPA,
    rather than the "public  interest" standard agreed to  by the
    parties.  56 F.E.R.C. at 61,993; 58 F.E.R.C. at 61,185.
    Each  of the  three parties  to the  Seabrook Power
    Contract ("SPC"), NU,  PSNH and the  State of New  Hampshire,
    waived  its right to file  a complaint under    206 regarding
    the rates contained in the agreement.  Section 12 of  the SPC
    also provided that:
    [E]ach [party] further agrees that in any
    proceeding  by the FERC under Section 206
    the  FERC  shall   not  change  the  rate
    charged under this Agreement  unless such
    rate  is found  to  be  contrary  to  the
    public interest.
    NU argues  that the Commission  violated the  "Mobile-Sierra"
    doctrine47 when  it  modified the  SPC  in disregard  of  the
    intent of the parties.
    47   This doctrine is based on the  companion cases of United
    Gas Pipe Line  Co. v. Mobile  Gas Service Co.,  
    350 U.S. 332
    (1956)  and FPC  v. Sierra  Pacific Power  Co., 
    350 U.S. 348
    (1956).
    -61-
    Under  the  Mobile-Sierra doctrine,  the Commission
    must respect certain private  contract rights in the exercise
    of its  regulatory powers.  Parties  to a contract may:   (1)
    waive  their  rights to  file  a  complaint challenging  that
    contract,  and (2) restrict  the power  of the  Commission to
    impose rate changes  under   206 to  cases in which it  finds
    the  rates contrary to the public interest   a more difficult
    standard  for  the  Commission  to meet  than  the  statutory
    "unjust and  unreasonable" standard  of    206.   See  Papago
    Tribal Utility Authority  v. FERC,  
    723 F.2d 950
    , 953  (D.C.
    Cir. 1983), cert. denied,  
    467 U.S. 1241
     (1984).   In Papago,
    the court held  that, regardless of the  parties' intent, the
    Commission retained, in any event,
    the indefeasible right . . . under    206
    to replace rates that are contrary to the
    public interest, "as where  [the existing
    rate   structure]    might   impair   the
    financial ability of  the public  utility
    to continue its  service, cast upon other
    consumers  an  excessive  burden,  or  be
    unduly discriminatory."
    Papago, 
    723 F.2d at 953
    , (quoting Sierra, 
    350 U.S. at 355
    ).
    The court  went on to  note that  "unduly discriminatory"  in
    this  context  "apparently  means  unduly  discriminatory  or
    preferential  to  the detriment  of  purchasers  who are  not
    parties to the contract."  Papago, 
    723 F.2d at
    953 n.4.
    In  this case,  seemingly for  the first  time, the
    Commission held that it also had the
    -62-
    authority   under  the   public  interest
    standard to  modify a contract where:  it
    may   be  unjust,   unreasonable,  unduly
    discriminatory  or  preferential  to  the
    detriment  of  purchasers  that  are  not
    parties to  the contract;  it is  not the
    result  of arm's length bargaining; or it
    reflects  circumstances where  the seller
    has  exercised  market  power   over  the
    purchaser.
    50  F.E.R.C. at 61,839 (emphasis added).  The ALJ interpreted
    that holding as follows:
    The  Commission  made clear  that  in the
    particular circumstances  surrounding the
    Seabrook  contract,  it  retains power
    through the "public interest"  language
    to    make   modifications    under   the
    traditional   just  and   reasonable  and
    nondiscrimination standards.
    53 F.E.R.C.  at  65,235.   The  standard established  by  the
    Commission, and  subsequently applied by  the ALJ,  conflates
    the  "just and  reasonable" and "public  interest" standards,
    thereby  circumventing  the  Mobile-Sierra  doctrine.     The
    distinction  between the  "just and  reasonable" and  "public
    interest"  standards  loses  its   meaning  entirely  if  the
    Commission may  modify a  contract under the  public interest
    standard  where it  finds  the contract  "may be  unjust [or]
    unreasonable."   The  parties'  express intent  was to  avoid
    review  of  rate  schedules  under the  just  and  reasonable
    standard.    Mobile-Sierra protects  their  right  to do  so,
    leaving the Commission  with the power  to modify rates  only
    when required by the public interest.
    -63-
    The  Commission  found that  the  SPC  might unduly
    discriminate  against entities not  parties to  the contract,
    and that there was no genuine arm's-length bargaining because
    NU and PSNH negotiated the agreement at a time when they knew
    they were about to  merge and have identical interests.   The
    Commission held  that, in  this context, it  could "carefully
    scrutinize the  rates, terms and conditions  of the contract"
    to determine if they were just.  
    Id.
    The Commission's  explanation for employing  a just
    and  reasonable  standard seems  to  us inadequate.    To the
    extent  the  Commission   is  relying  on   NU's  prospective
    ownership of PSNH, it is unclear why the Commission should be
    concerned    about   protecting   PSNH   from   a   perceived
    disadvantageous arrangement imposed by its  prospective owner
    since any disadvantage visited on  the prospective subsidiary
    will be borne by its owner.  If NU chooses  to allocate risks
    among its operating subsidiaries  and one of its subsidiaries
    is  disfavored in  this calculation,  there would seem  to be
    little justification for the Commission stepping in on behalf
    of the disfavored subsidiary absent some threat to the public
    interest.
    As for the seller's  market power, reliance on this
    factor  threatens  to  erode  the  Mobile-Sierra doctrine  so
    substantially that  a fuller explanation  from the Commission
    is required before  proceeding down this  route.  After  all,
    -64-
    some  measure of  market power  could be  present in  a large
    number  of  contracts.    A  case-by-case  inquiry  into  the
    presence  and extent of market  power would inject  a new and
    potentially  time-consuming  element  into the  Mobile-Sierra
    analysis, and it is not entirely  clear in any event why  the
    Commission should protect a buyer who voluntarily enters into
    an agreement with a dominant seller.
    The  most attractive case  for affording additional
    protection, despite  the presence of a contract, is where the
    protection is  intended to  safeguard the interests  of third
    parties,  notably the  buyer's customers.   The Mobile-Sierra
    doctrine itself allows  for intervention by FERC  where it is
    shown  that the  interests of  third parties  are threatened.
    Mobile,  350  U.S.  at  344-45;  Sierra,  
    350 U.S. at 355
    .
    However, the  standard to be  applied, as  formulated by  the
    Supreme  Court, is  the  protection of  outside parties  from
    "undu[e] discriminat[ion]"  or  imposition of  an  "excessive
    burden."  Sierra,  
    350 U.S. at 355
    .  If  there is some reason
    for departing from this public interest standard as framed by
    the Supreme Court, the Commission has not supplied it.
    We  assume, without  deciding, that:   (1)  FERC is
    correct  in its assertion that the State of New Hampshire did
    not adequately represent the  interests of non-parties to the
    contract,  and  that,  therefore,  the SPC  may  have  unduly
    discriminated  against those non-parties; and (2) the alleged
    -65-
    lack of arms'-length bargaining among NU,  PSNH and the State
    of  New Hampshire gave  the Commission the  right to evaluate
    the SPC.  We hold, however,  that the Commission was bound to
    follow  the Mobile-Sierra  doctrine as explicated  by Papago,
    and therefore should have evaluated  the SPC under the public
    interest standard, not the just and reasonable standard.
    We  therefore remand this issue for reconsideration
    by FERC under the public interest standard.48
    IV.  SUMMARY.
    We affirm  the Commission's orders in  all respects
    with the exception of its modifications of the Seabrook Power
    Contract filed with the merger  proposal which we remand  for
    consideration under the public interest standard.
    48   We have considered, but find unpersuasive, NU's argument
    that FERC  committed error  when it disrupted  the bankruptcy
    settlement by modifying the Capacity Interchange Agreements.
