    THE PUBLIC UTILITIES COMMISSION has requested an advisory opinion,
    pursuant to Public Utilities Code section 854, subdivision (b)(2), on the following
    questions:
    1
    90-507
    (1)		   Will the proposed acquisition of San Diego Gas and Electric Company by
    SCEcorp, the parent of Southern California Edison Company, adversely
    affect competition?
    (2)		   What mitigation measures could be adopted to avoid adverse effects on
    competition?
    CONCLUSION
    (1)		   The proposed acquisition will adversely affect competition in wholesale
    and retail electric power markets.
    (2)		   Some of the adverse effects can be avoided by appropriately conditioning
    the merger, but some of the effects are not susceptible to relief through
    conditions.
    Accordingly, we have concluded that the acquisition cannot be approved under section
    854.

    ANALYSIS
    On November 30, 1988, SCEcorp, the holding company of Southern California
    Edison Company (SCE), and San Diego Gas and Electric Company (SDG&E) announced
    a merger1 of their two firms. Public Utilities Commission (PUC) is conducting its review
    of the proposal under Public Utilities Code section 854.2
    Subdivision (b) of section 854 provides in pertinent part:
    “Before authorizing the acquisition or control of any electric, gas, or
    telephone utility organized and doing business in this state . . ., the
    commission shall find that the proposal does both of the following:
    “(1) Provide net benefits to ratepayers in both the short-term and
    long-term, and provide a ratemaking method that will ensure, to the fullest
    extent possible, that ratepayers will receive the forecasted short- and long-
    term benefits.
    “(2) Not adversely affect competition. In making this finding, the
    commission shall request an advisory opinion from the Attorney General
    regarding whether competition will be adversely affected and what
    mitigation measures could be adopted to avoid this result.”
    As provided by subdivision (b)(2), the commission has requested the
    Attorney General’s advisory opinion on the competitive effects of the
    merger.
    1
    For purposes of this opinion, and of the PUC’s review, there is no difference between an
    acquisition and a merger, and the terms are used interchangeably here.
    2
    The Federal Energy Regulatory Commission has concurrent jurisdiction to disapprove the
    merger, and it is also presently conducting hearings on the proposal.
    4
    90-507
    I.     THE NATURE OF THIS OPINION
    The requirement that the PUC seek the Attorney General’s advisory opinion is the
    product of a 1989 amendment to the statute (Stats. 1989, ch. 484, § 1), and this is the first
    such opinion to be rendered under the amended statute. Therefore, before dealing with
    the issues presented by the merger, we pause to address a question already raised in the
    course of the commission’s proceedings: What is the nature of the Attorney General’s
    advisory opinion?
    A.     FUNCTION OF THE ADVISORY OPINION
    Since the Legislature is presumed to be aware of all statutes and judicial decisions
    in an area in which it is legislating (e.g., Brown v. Kelly Broadcasting Co. (1989) 
    48 Cal. 3d 711
    ; People v. Slaughter (1984) 
    35 Cal. 3d 629
    ), we assume that the Legislature
    required the PUC to seek the Attorney General’s advice because he is the state official
    responsible for enforcement of state and federal antitrust laws (15 U.S.C. §§ 15c–15h;
    Bus. & Prof. Code, §§ 16750, 16752–16754.5, 16760; Hawaii v. Standard Oil Co. (1972)
    
    405 U.S. 251
    ; Georgia v. Pennsylvania Rd. Co. (1945) 
    324 U.S. 439
    ; Younger v. Jensen
    (1980) 
    26 Cal. 3d 397
    ) and is presumed to possess the expertise best suited to assessing
    the competitive effects of a utility merger.
    The statute characterizes the opinion as advisory. Consequently the opinion does
    not control the PUC’s finding under section 854, subdivision (b)(2); however, the advice
    is entitled to the weight commonly accorded an Attorney General’s opinion (see, e.g.,
    Moore v. Panish (1982) 
    32 Cal. 3d 535
    , 544 (“Attorney General opinions are generally
    accorded great weight”); Farron v. City and County of San Francisco (1989) 
    216 Cal. App. 3d 1071
    ) and that which is given to the expert views of an administrator charged
    by the Legislature with implementing a statute (see, e.g., Addison v. Department of Motor
    Vehicles (1977) 
    69 Cal. App. 3d 486
    , 493 (agency’s construction of a statute it is charged
    with enforcing is entitled to great weight)).
    B.     ATTORNEY GENERAL’S STATUS AS INTERVENOR
    As the commission is aware, the Attorney General has intervened in the
    administrative proceedings it is conducting (and those before the Federal Energy
    Regulatory Commission (FERC)) on this merger, as a part of his antitrust enforcement
    and consumer protection responsibilities.
    The Legislature was aware that, at least in the present case, the Attorney General
    was likely to be a party to the PUC’s administrative review when the advisory opinion
    was to be requested. In fact, both houses of the Legislature were advised, before the 1989
    5
    90-507
    amendment to section 854, that the Attorney General was already examining the
    proposed merger and intended to take a position on its merits before the PUC.3 Since the
    Legislature proceeded to enact subdivision (b)(2) as it did, with no special procedure for
    this merger, we conclude that the Legislature understood we would be discharging this
    essentially quasi-judicial function at the same time we were likely to be engaged in the
    administrative litigation before the PUC. Our posture is not materially different in this
    respect from that of the U.S. Department of Justice (USDOJ), which frequently renders
    advisory opinions to federal agencies on antitrust aspects of a pending matter and then
    participates in the agencies’ administrative hearings. (See, e.g., 16 U.S.C. § 1828 (advice
    on proposed bank merger); 30 U.S.C. § 184 (advice to Secretary of Interior on antitrust
    aspects of proposed coal lease); 42 U.S.C. § 2135 (advice to Nuclear Regulatory
    Commission on antitrust aspects of applications for nuclear licenses).) Indeed, we note
    that in the ongoing FERC proceedings on this merger, USDOJ has not yet taken any
    formal position on the merits but is actively participating in the FERC hearings.
    C.        EVIDENTIARY BASIS OF THIS OPINION
    We are rendering this opinion before commencement of the commission’s
    hearings, as requested by the PUC. We appreciate the purpose of the commission’s
    timing, to give the parties maximum time to respond to the issues we raise. We know the
    commission understands that this requires us to base our conclusions on less than the full
    record to be developed here.
    The condition of the evidence does not present an obstacle to our rendering the
    opinion at this time. The parties have filed testimony with this commission, and there has
    already been substantial discovery on the competitive issues. An even larger body of
    evidence has already been filed with the FERC, which is further along in its process,
    having just concluded approximately three months of hearings. And the Attorney General
    has, as previously noted, been reviewing the merger for over a year, discussing the issues
    with the parties, examining the evidence available, and securing his own technical advice.
    We have therefore been able to draw on the ample information already available and
    thoroughly analyzed for that purpose.
    In the discussion that follows, the evidentiary basis for our conclusions are noted.
    They draw on (1) the prefiled material before this commission, (2) the discovery
    materials developed in the PUC proceeding, (3) evidence and prefiled testimony in the
    FERC proceeding, and (4) the oral proceedings before the FERC.4

    II.     THE PROPOSED MERGER
    SCE and SDG&E are vertically-integrated electric utilities with adjacent retail
    territories. SCE, serving an area from the southern part of the Central Valley through
    Orange and Riverside Counties, is the second largest power utility in the nation (based on
    number of customers). SDG&E, with San Diego and a part of southern Orange Counties,
    is the twenty-first. Together they would create the largest energy utility in the U.S., with

    20 percent more customers than the current largest, Pacific Gas and Electric Company
    (PG&E). (See Table 1.)
    In addition to their electric utility operations, SDG&E operates a gas utility
    serving roughly the same territory as the electric utility; Edison has, until now, not been a
    gas utility. SDG&E also has two unregulated subsidiaries: Mock Resources, which buys
    and sells oil and gas, and Pacific Diversified Capital, itself a holding company with
    subsidiaries serving the utility and real estate markets. SCEcorp owns literally scores of
    unregulated subsidiaries, of which the most significant, for present purposes, is the
    Mission Group, which in turn owns Mission Energy, a joint venturer in independent
    power production facilities, and several other firms active in utility-related enterprises.
    III.   PUBLIC UTILITIES CODE SECTION 854
    Before considering the proposed merger under section 854, subdivision (b),
    we examine the requirements of the statute.
    A.     PURPOSE OF THE STATUTE
    The Public Utilities Commission, as a part of the broad regulatory authority it
    exercises over utilities doing business in California (Cal. Const., art. XII, § 6), has the
    authority to approve any contract or other transaction a utility proposes to enter. (Pub.
    Util. Code, § 701.) That would include any merger or acquisition agreement. (Pub. Util.
    Code, §§ 816, 852, 854.)
    At a minimum, any transaction examined by the PUC would be tested against the
    traditional standard, whether it appears to be in the public interest. (Pub. Util. Code,
    § 854, subd. (c); see also Pub. Util. Code, § 852.) One element of that standard is whether
    the transaction is consonant with California and United States antitrust laws and the
    policies underlying those laws. (Northern California Power Agency v. Public Utilities
    Commission (1971) 
    5 Cal. 3d 370
    ; see also California v. Fed. Power Comm’n. (1962) 
    369 U.S. 482
    ; Industrial Communications Systems, Inc. v. Pacific Tel & Tel. Co. (9th Cir.
    1974) 
    505 F.2d 152
    .) The federal law on the competitive effects of mergers is found in
    section 7 of the Clayton Act (15 U.S.C. § 18) and sections 1 and 2 of the Sherman Act
    (15 U.S.C. §§ 1, 2). California law contains no specific provisions governing mergers
    (State of California ex rel. Van de Kamp v. Texaco, Inc. (1988) 
    46 Cal. 3d 1147
    ), but the
    state’s statutory policy on economic competition is contained in the Cartwright Act (Bus.
    & Prof. Code, § 16720 et seq.).
    Thus, Public Utilities Code section 854’s requirement that the commission make
    explicit findings on the competitive effects of a merger underscores the antitrust
    8
    90-507
    component of the commission’s public interest inquiry and ensures that the issue will be
    examined, and a finding made, whether or not any party to the administrative review
    raises the issue. Furthermore, as we note below, the wording of the statute reflects
    specific requirements of the commission’s review that differ from its traditional standards
    in a public-interest examination and from the familiar Clayton Act merger analysis.
    B.		     MEANING OF THE PHRASE “ADVERSELY
    AFFECT COMPETITION”
    The phrasing of the statute, requiring the PUC to find that the proposed merger
    does “not adversely affect competition,” is uncommon to statutory law. The more
    familiar phrase in merger analysis is whether “the effect of such acquisition may be
    substantially to lessen competition or tend to create a monopoly.” (Clayton Act, § 7.) Did
    the Legislature purposefully depart from the substantial body of Clayton Act
    jurisprudence in defining the issue for the PUC?
    The phrase “not adversely affect competition” does not appear in any other
    California statute and is found only occasionally in the federal code.5 If the Legislature
    had any model in mind, it probably lies in the recent jurisprudence of the PUC itself,
    which has, during the 1980s, had several occasions to make findings whether proposals
    threatened adversely to affect competition.6 But those cases do not reveal any recurring,
    systematic standard for measuring the effects of a merger.
    5
    E.g., 15 U.S.C. § 2008 (Environmental Protection Agency may adjust auto manufacturer’s
    penalty for failing to meet fleet fuel economy standards upon certification by Federal Trade Commission
    that relief “is necessary to prevent a substantial lessening of competition”); 15 U.S.C. § 2058 (rules on
    consumer product safety to include findings on “minimizing adverse effects on competition”); 30 U.S.C.
    § 184(1)(2) (before leasing coal reserves, Secretary of Interior must consult with Attorney General on
    whether proposed lease “would create or maintain a situation inconsistent with the antitrust laws”); 33
    U.S.C. §§ 1503, 1506 (licensing of deepwater ports to consider whether license “would adversely affect
    competition, restrain trade, promote monopolization, or otherwise create a situation in contravention of
    the antitrust laws”); 42 U.S.C. §§ 8217, 8235h (participation by utilities in residential energy conservation
    programs require finding that it “may not have a substantial adverse effect on competition”); 49 U.S.C.
    § 10705a (Interstate Commerce Commission must investigate protests that joint rates filed by railroads
    “will have an adverse effect on competition”); 49 U.S.C. § 11344 (in reviewing a proposed merger, ICC
    must consider “whether the proposed transaction would have an adverse effect on competition among rail
    carriers in the affected region” and cannot approve the proposal if it finds “there is likely to be substantial
    lessening of competition, creation of a monopoly, or restraint of trade . . . and . . . the anticompetitive
    effects of the transaction outweigh the public interest in meeting significant transportation needs”).
    6
    E.g., Application of Airport Limousine Service of Sunnyvale, Inc. for Authority to Add
    Scheduled Van Service Between Points in San Francisco County and San Francisco International Airport
    to Its Passenger Stage Authority (1988) Decision No. 8809068 (whether expansion of applicant’s airport
    service would have “adverse effect on the current level of competition”); Application of McCaw
    Communications of Stockton, Inc. for Authorization to Acquire Control of Stockton Cellular Telephone
    9
    90-507
    1.      Must the Effects be “Substantial”?
    Several of the PUC cases, and various federal statutes (see footnote , supra), use
    the phrase “substantial adverse effect,” language similar to the Clayton Act’s “lessen
    competition substantially.” Omission of the word “substantial” from section 854 was
    presumably deliberate and indicates the legislative intent that a merger causing any
    reduction in competition may not be approved.7 (Santa Fe Transp. v. State Board of
    Equal. (1959) 
    51 Cal. 3d 531
    , 539 (“By failure to use any such limiting words the
    Legislature indicated its intention of not so limiting or circumscribing the meaning or
    scope of the act. . . . [T]his court may not supply any language which the Legislature
    must be deemed to have omitted intentionally.”); Kaiser Steel Corp. v. County of Solano
    (1979) 
    90 Cal. App. 3d 662
    , 667 (“Where the Legislature omits a particular provision in a
    later enactment related to the same subject matter, such deliberate omission indicates a
    different intention which may not be supplanted in the process of judicial
    Company (1988) Decision No. 8806012 (“The proposed acquisition will not adversely affect competition
    in the Stockton cellular market. Competition between the two cellular carriers, Cellular and Sacramento
    Valley Limited Partnership will continue as before.”); Application of Pacific Telesis Group for
    Authorization to Acquire Control of Gencom Incorporated, Tel-Page, Inc., Intrastate Radio-Telephone,
    Inc. of San Francisco and Delta Mobile Radio Service, Inc. Through the Acquisition of the Stock of
    Communications Industries, Inc. (1986) Application No. 85–08–023 (proposed ALJ decision) (“The
    present state of the paging industry indicates that the proposed acquisition will have no significant
    adverse effect upon competition in the paging industry.”); Application of Continental Telephone
    Company of California for Authorization to Merge with Continental Transition Corporation (1983) 13
    C.P.U.C.2d 274 (“The merger will have no adverse [e]ffect on competition as Pacific Telesis and other
    telephone corporations are experiencing changes in corporate ownership and need to establish operating
    subsidiaries to perform nonregulated operations in the same manner as Continental.”); Petition for
    Rehearing of D. 82 06 051 (SoCal Edison Co.) (1982) 9 C.P.U.C.2d 765 (“The record does not support
    Cities’ contention that granting a certificate to Edison for the [Balsam Meadow Powerhouse] will have an
    adverse competitive effect.”)
    7
    There could, of course, easily be mergers that have no effect whatsoever on competition.
    Section 854 applies to acquisitions of utilities by non-utilities, or by wholly different kinds of utilities
    (e.g., electric utility by telephone company), where one would not expect to find any competition between
    the merging firms.
    The fact that the Legislature amended section 854 in 1989, after hearings were held on the
    proposed SCE-SDG&E merger, does not illuminate this inquiry. While the Legislature is chargeable with
    knowledge of the case law and academic writings on the forms of competition between adjacent electric
    utilities, the two firms have steadfastly maintained that they are not in competition at all. Section 854
    could be read as simply putting them to their word. In any event, with the reach of the section at least
    theoretically extending beyond this merger, we conclude the pendency of the SCE-SDG&E merger when
    the section was amended has no significance to this inquiry.
    10
    90-507
    construction.”).) We must conclude that omission of “substantial” reflects a purposeful
    departure from the standard of similar statutes.8
    It does not necessarily follow that any merger having even an “insubstantial”
    effect on competition must be rejected by the commission. The merging firms might
    both be minor participants in some market where other firms are the dominant forces; in
    that case, the merger would eliminate one competitor but its loss would be
    inconsequential and the acquiring firm would remain an unimportant force in the market.
    We believe the term “adversely affect” conveys a notion of effects sufficiently weighty to
    be characterized as harmful and that only in the absence of such effects could the merger
    be approved under section 854.
    One implication of the absence of the word “substantial” is that this statute does
    not permit the PUC to dismiss an injury to competition on the ground that commerce in
    the good or service is small. There is no room in this statute, for example, to find that
    while a given market may be adversely affected by a merger the dollar volume of
    commerce in that market is small when compared to the overall revenues of the merging
    firms. If the effects on competition in a market are sufficient to be called “adverse,”
    those effects cannot be dismissed because the market itself is relatively small.
    The conclusions we draw here about the SCE-SDG&E merger do not depend on
    this question. Because we find that the harmful effects of this merger are “substantial,”
    even as that term is used in section 7 of the Clayton Act, it is not necessary for us to
    determine here how much more stringent section 854 is than the Clayton Act. And
    because a sophisticated model for measuring the competitive effects of mergers has been
    developed under the Clayton Act, we avail ourselves of that analytic framework here.
    2.      Does the Statute Reach Incipient Injury to Competition?
    A major reason for Congress passing the Clayton Act in 1914 was to proscribe
    acquisitions which might not actually destroy existing competition, the standard under the
    Sherman Act (United States v. Philadelphia National Bank (1963) 
    374 U.S. 356
    ;
    Northern Securities Co. v. United States (1904) 
    193 U.S. 197
    ), but which have a
    tendency to do so. (United States v. Penn-Olin Co. (1964) 
    378 U.S. 158
    ; Brown Shoe Co.
    v. United States (1961) 
    370 U.S. 294
    .) Does deviation from the Clayton Act language
    reflect a desire to ignore a merger’s incipient threats to competition? We do not believe
    so. The language employed by the Legislature does not follow that of the Sherman Act
    8
    The present language was introduced in its final form in the original December 5, 1988, version
    of Senate Bill Number 52, which amended section 854. None of the committee analyses or other
    legislative materials on the bill discuss the specific language at issue here.
    11
    90-507
    either. In our view, the word “affect” is broad enough to embrace both immediate harm
    and long-term effects on competition. Once again, we will apply the same notion of
    competitive effects found in the Clayton Act cases.
    One implication of this conclusion is that we, and the commission, must consider
    both actual and potential competition. Thus, even if the merging firms are not now in
    competition in a given market, if there is evidence showing that one is a potential
    competitor of the other, the elimination of the potential competitor constitutes an adverse
    effect on competition within the meaning of section 854. (See, e.g., United States v.
    Falstaff Brewing Corp. (1973) 
    410 U.S. 526
    ; United States v. El Paso Natural Gas Co.
    (1964) 
    376 U.S. 651
    .)
    3.		    Must an Impermissible Injury to Competition Constitute an
    Antitrust Violation?
    One clear implication of the statutory language is the intention not merely to focus
    on “violations” of the antitrust laws. The Legislature could simply have said that the PUC
    shall disapprove the merger upon a finding that it would violate the antitrust laws.
    Instead, it phrased the issue more generally, in terms of the competitive effects of the
    merger.9
    Consequently, the commission need not find all the elements of a violation of
    section 7 of the Clayton Act before disapproving the merger. Certainly technical defenses
    like standing and equitable defenses like unclean hands have no place in the
    commission’s review.10 Likewise, we see no room in the statutory language for economic
    9
    Cf. Alabama Power Company v. Nuclear Regulatory Commission (11th Cir. 1982) 
    692 F.2d 1362
    , 1368 (section 105 of the Atomic Energy Act (42 U.S.C. § 2135), requiring review to determine
    whether license for nuclear generating facility “would create or maintain a situation inconsistent with the
    antitrust laws,” reaches situations “which would not . . . in fact violate any antitrust law” because “a
    traditional antitrust enforcement scheme is not envisioned, and a wider one is put in place.”).
    10
    One such technical defense to be disregarded here is the distinction between a “merger” or
    “acquisition” and a “combination” for purposes of the Cartwright Act. In State of California ex rel.
    Van de Kamp v. Texaco, Inc. (1988) 
    46 Cal. 3d 1147
    , the Supreme Court held that the 1907 Legislature
    drew a distinction between a combination, in which the combining parties retained their separate
    identities, and a merger, in which one of the parties was absorbed into the other. According to the Texaco
    court, the latter was seen, for historical reasons, to be different than a combination and therefore outside
    the language of Business and Professions Code section 16720. Since a technical violation of the statute is
    not at issue, but rather the competitive policies underlying the Cartwright Act, California antitrust policy
    is, in our view, appropriately considered even though the merger itself falls outside the proscriptions of
    the Cartwright Act. As a practical matter, we know of no articulated difference between the policies
    underlying the Cartwright Act and those at the foundation of the Clayton and Sherman Acts (see, e.g.,
    Marin County Bd. of Realtors, Inc. v. Palsson (1976) 
    16 Cal. 3d 920
    ) that would alter the conclusions we
    12
    90-507
    defenses that are sometimes raised in merger cases to argue that anticompetitive effects
    should be ignored—for example because easy market entry will prevent collection of
    monopoly rents. Indeed, because the statute separates price effects and competitive
    effects (see section III.C, post), such defenses based on the difficulties a dominant firm
    might have translating its dominance into higher prices are irrelevant. Since we have seen
    no persuasive evidence of any such meritorious defense in the merger before us, this
    observation is made only in the interest of a fuller explication of the statute.
    4.      Are Non-Competitive Antitrust Considerations Relevant?
    While in some respects section 854, subdivision (b)(2), imposes a higher test for a
    prospective merger than the Clayton Act, in other respects the test is more limited, being
    specifically addressed to those antitrust policies pertaining specifically to competitive
    effects. The courts have long recognized that the antitrust laws in general and the Clayton
    Act in particular were aimed not only at preventing firms from rising prices due to market
    power:
    “Other goals of the law were the prevention of excessive levels of
    industrial concentration because of the political and social effects of
    concentrated economic power and the fostering of productive efficiency,
    organizational diversity, technological innovation and the maintenance of
    opportunities for small and regional businesses to compete.” (National
    Association of Attorneys General, Horizontal Merger Guidelines (1987)
    p. 4, citing Brown Shoe Co. v. United States (1962) 
    370 U.S. 294
    , 315–16.)
    While some of these goals fall within the rubric of protecting competition, others
    refer more broadly to the antitrust laws’ role in “providing an environment conducive to
    the preservation of our democratic political and social institutions” (Northern Pacific
    Railway Co. v. United States (1958) 
    356 U.S. 1
    , 4, n7). Those factors must be considered
    in the commission’s broader public interest review, but they are not implicated by
    subdivision (b)(2) of section 854.11
    reach in this opinion.
    11
    For example, we understand some opposition to the merger in San Diego is based on the desire
    to have a local utility, civic pride in the existence of SDG&E, a feeling that a locally-based utility will be
    more responsive to local concerns, and hostility to regional domination from Los Angeles. None of these
    claims, even if they are widely felt and well founded, concerns the merger’s effect on competition, so they
    have no place in our review under subdivision (b)(2) of Public Utilities Code section 854. But precisely
    such preferences for regional business, antagonism to economic concentration, and the desire for
    industrial diversity lie at the heart of the original purposes of the Clayton and Sherman Acts. (Brown Shoe
    Co. v. United 
    States, supra
    , 
    370 U.S. 294
    , 315–16.) They are therefore highly pertinent to the
    commission’s assessment of the public interest — both directly, as considerations affecting the public
    interest, and indirectly as values reflected in the antitrust laws. In this same connection, we note that SCE
    13
    90-507
    C.		    RELATIONSHIP OF COMPETITIVE EFFECTS TO OTHER PUBLIC
    INTEREST FACTORS
    The legal standard for examining a merger under section 854 is similar to the
    general public- interest analysis the commission routinely must employ when antitrust
    issues arise. However, in one respect section 854 requires departure from past practice.
    Previously, when the commission found that a proposal impinged on the policies
    underlying state or federal antitrust law, the commission could nonetheless approve the
    application if it found that overall its detriments were outweighed by its benefits—for
    example, if it found that the proposal threatened to injure competition but promised
    compensating ratepayer benefits.12 No such result is permitted by section 854. The statute
    plainly states its requirements in the conjunctive: the commission must find “both . . .
    [that the merger [p]rovide net benefits to ratepayers” (Pub. Util. Code, § 854, subdiv. (b),
    (b)(1), emphasis added) and that it “[n]ot adversely affect competition” (Pub. Util. Code,
    § 854, subdiv. (b)(2)).13
    Thus, if the merger is found to “adversely affect competition,” it cannot be
    approved, no matter how large the “net benefits to ratepayers.”
    IV.		   ANALYZING COMPETITIVE EFFECTS
    A.		    HORIZONTAL ANALYSIS
    has recently committed itself to an aggressive program of affirmative action in management, workforce,
    and contracting, which are plainly pertinent to the commission’s public interest determination. We view
    all such considerations as falling within the general weighing of the public interest mandated by
    subdivision (c) of section 854.
    12
    “ ‘Although the Commission is not bound by the dictates of the antitrust laws, it is clear that
    antitrust concepts are intimately involved in a determination of what action is in the public interest, . . .
    Nor are the agencies strictly bound by the dictates of these laws, for they can and do approve actions
    which violate antitrust policies where other economic, social and political considerations are found to be
    of overriding importance.’ ” (Northern California Power Agency v. Public Utilities 
    Commission, supra
    , 
    5 Cal. 3d 370
    , 377–78, quoting Northern Natural Gas Co. v. Federal Power Com’n (1968) 
    399 F.2d 953
    ,
    958, 960; see also Gulf States Utilities v. F.P.C. (1973) 
    411 U.S. 747
    .)
    13
    In contrast, subdivision (c) of section 854 expressly prescribes such a balancing in considering
    seven other factors pertinent to the public interest:
    “Before authorizing the acquisition or control of any . . . utility . . . the
    commission shall consider each of the criteria listed in paragraphs (1) to (7), inclusive,
    and find, on balance, that the acquisition or control proposal is in the public interest.”
    14
    90-507
    Traditionally, the antitrust implications of a proposed merger are analyzed by a
    well-developed model that seeks to measure the market power of each of the merging
    firms and of the proposed consolidated company. The model begins with characterization
    of each relevant product market affected by the merger. The product market refers to the
    range of products or services that are relatively interchangeable, so that pricing decisions
    by one firm are influenced by the range of alternative suppliers available to the purchaser.
    The utility industry is one of the service industries where the courts tend to group a
    “cluster of services” into a single market. (E.g., United States v. Connecticut National
    Bank (1974) 
    418 U.S. 656
    ; United States v. Phillipsburg Nat. Bank (1970) 
    399 U.S. 350
    ;
    United States v. Grinnell Corp. (1966) 
    384 U.S. 563
    .)
    The analysis then proceeds to determination of the relevant geographic market for
    each product market. The relevant geographic market is defined as the area in which the
    sellers compete and in which buyers can practicably turn for supply. (United States v.
    Connecticut National 
    Bank, supra
    , 
    418 U.S. 656
    ; FTC v. Procter & Gamble Co. (1967)
    
    386 U.S. 568
    ; United States v. Pabst Brewing Company (1966) 
    384 U.S. 546
    .) In
    drawing the boundaries of the geographic market, courts look to industry recognition of
    distinct marketing patterns. (United States v. Phillipsburg National 
    Bank, supra
    , 
    399 U.S. 350
    ; United States v. Connecticut National 
    Bank, supra
    , 
    418 U.S. 656
    .)
    Within a relevant product or geographic market may be found several relevant
    sub-markets, “which, in themselves, constitute product markets for antitrust purposes.”
    (Brown Shoe Co. v. United 
    States, supra
    , 
    370 U.S. 294
    , 325; see also United States v.
    Continental Can Co. (1964) 
    378 U.S. 411
    ; United States v. Aluminum Co. of America
    (1964) 
    377 U.S. 271
    (1964).) A relevant sub-market is identified by “practical indicia
    such as industry or public recognition of the submarket as a separate economic entity, the
    product’s peculiar characteristics and uses, unique production facilities, distinct
    customers, distinct prices, sensitivity to price changes, and specialized vendors.” (Brown
    Shoe Co. v. United 
    States, supra
    , 370 U.S. at 325.)
    These two steps define the “area of effective competition.” (Id., at p. 324.) The
    merger’s effect in each such market is then assessed by examining the market power of
    each firm and of the merged company. A merger which gives the merging firms the
    power to control prices or to exclude competition is unlawful. (United States v. Grinnell
    
    Corp., supra
    , 
    384 U.S. 563
    , 571; United States v. E.I. Du Pont De Nemours & Co. (1961)
    
    351 U.S. 777
    , 791.)
    The market power derived from the merger of two competitors is traditionally
    measured in terms of concentration, or market shares. (See, e.g., United States v. General
    Dynamics Corp. (1974) 
    415 U.S. 486
    , 497; Federal Trade Commission v. PPG
    Industries, Inc. (D.C. Cir. 1986) 
    798 F.2d 1500
    .) The concentration of the market and the
    15
    90-507
    contribution of the merger to that concentration is measured by use of the Herfindahl-
    Hirschman Index (HHI), which calculates the sum of the squares of each firm’s market
    share.14 (Ibid.) The U.S. Department of Justice periodically promulgates Merger
    Guidelines stating its enforcement policy in reviewing proposed mergers. The current
    version, published in 1984, states the general policy that a merger resulting in a market
    with an HHI over 1800, to which the merger contributed at least 50, will ordinarily be
    challenged as unlawful, as will a merger resulting in a market with an HHI between 1200
    and 1800, to which the merger contributed at least 100.15 (United States Department of
    Justice, Merger Guidelines (1984) reprinted in 4 Trade Reg. Rep. (CCH) ¶ 13,103.) The
    fifty state Attorneys General have promulgated their own standards, which are somewhat
    more restrictive, accepting a merger adding only half as large an increment to the HHI in
    markets experiencing concentration over the preceding three years. (National Association
    of Attorneys General, Horizontal Merger Guidelines (1987) reprinted in 52 Antitrust &
    Trade Reg. Rep. (BNA) No. 1306 (Special Supp.) (“NAAG Guidelines”).) Both the
    USDOJ and NAAG policies emphasize that HHI calculations are very strong evidence of
    a violation. However, even in the absence of high HHIs, other factors may support the
    finding of a violation.
    The issue of market share or the level of concentration is only important in the
    absence of direct evidence of the power to control prices or exclude competition. Where
    such direct evidence is presented, it is not necessary to prove any specific market share.
    (Moore v. Jas. H. Matthews & Co. (9th Cir. 1977) 
    550 F.2d 1207
    , 1219 (“Even in the
    absence of empirical proof of market shares (usually the best indicator of monopoly
    power) the requisite power can also be demonstrated by evidence of the exercise of actual
    control over prices or exclusion of competitors.”; In re IBM Peripheral EDP Devices, etc.
    (N.D. Cal. 1979) 
    481 F. Supp. 965
    , 976 (“If defendant has, in the past, successfully
    controlled price or excluded competition, that is direct and convincing evidence that it
    had the power to do so.”); Power Replacements Corp. v. Air Preheater Co., Inc. (E.D.Pa.
    1973) 
    356 F. Supp. 872
    , 896 (Failure of plaintiff to provide actual market share evidence
    “is no comfort to the defendants, however, since we have concluded that Air Preheater’s
    power to exclude the competition of Power Replacements has been proven directly, so
    that no inference from a market share percentage is necessary”).)
    14
    Thus, a three-firm market in which the respective shares are 50%, 30%, and 20%, the HHI is
    .25 (i.e., 50%2) plus .09 plus .04, or .37, which by convention is multiplied by 10,000 for convenience,
    yielding 3700.
    15
    An HHI of 1800 reflects market concentration roughly comparable to four firms controlling
    70% of a market, and an HHI of 1000 to a market in which four firms control 50%. The department adds
    a proviso that it will likely challenge any merger of a dominant firm (over 35%) with any firm having at
    least a 1% market share.
    16
    90-507
    B.     VERTICAL MERGERS
    This familiar model addresses only horizontal effects of a merger—the effects
    from consolidation of two firms’ operations at a single level of the chain of markets from
    production to ultimate sale (e.g., two manufacturers or two retailers). In industries where
    firms have vertically integrated—conducting operations at several levels—a merger
    potentially presents an independent set of problems, of foreclosure of competitors’ access
    to suppliers or customers. (Ford Motor Co. v. United States (1972) 
    405 U.S. 562
    ;
    Standard Oil Co. of California v. United States (1949) 
    337 U.S. 293
    .) These problems
    are assessed not by calculation of market shares but from a realistic assessment of the
    potential for market manipulation to the disadvantage of competitors or consumers.
    (Brown Shoe Co. v. United 
    States, supra
    , 
    370 U.S. 294
    , 328–31; United States v.
    American Cyanimid Co. (2d Cir. 1983) 
    719 F.2d 558
    .) The U.S. Supreme Court has
    consistently recognized the serious problems inherent in vertical mergers. Each such
    merger to reach the Court was voided. (Ford Motor Co. v. United 
    States, supra
    , 
    405 U.S. 562
    ; Brown Shoe Co. v. United 
    States, supra
    , 
    370 U.S. 294
    ; United States v. E.I. Du Pont
    De Nemours & 
    Co., supra
    , 
    351 U.S. 777
    ; United States v. Yellow Cab Co. (1947) 
    332 U.S. 218
    .)
    Vertical mergers present special problems when the merging parties control an
    essential, or “bottleneck” resource, which can be abused to exclude competitors or
    otherwise gain advantage in other markets. (E.g., United States v. Griffith (1948) 
    334 U.S. 100
    ; Associated Press v. United States (1945) 
    326 U.S. 1
    ; United States v. St. Louis
    Terminal (1912) 
    224 U.S. 383
    .) In the electric utility industry, the transmission grid has
    often been found to be a bottleneck resource. (E.g., Otter Tail Power Co. v. United States
    (1973) 
    410 U.S. 366
    ; Utah Power & Light (1988) 45 F.E.R.C. ¶ 61,095.)
    The proposed SCE-SDG&E merger is both a horizontal and a vertical merger.
    Each firm is itself vertically integrated. The merger of the two firms’ operations at a
    given level (e.g., bulk power production) must be analyzed horizontally. Additionally, the
    acquisition must be examined to determine whether SCE is acquiring any bottleneck
    resources that can be used to disadvantage competitors in other markets.
    One other distinction to be kept in mind is the different roles a firm may play as
    both buyer and seller. Antitrust analysis of mergers typically focuses on the combining
    firms’ capacity to manipulate selling price—to raise the price others must pay for the
    combined firms’ products. But there is no less concern for those cases where a merger
    gives the resulting entity unfair power to control purchase prices by eliminating
    competition between the merging firms in the bidding for up-stream resources. This kind
    of power is technically referred to as “monopsony power,” as contrasted to “monopoly
    17
    90-507
    power,” although the terms “buyer market power” and “seller market power” are more
    descriptive.
    V.     THE COMPETITIVE SETTING
    Electric utilities were once thought to be “natural monopolies,” with the fixed
    costs of service so high that there was no role for competition. At retail, every state has
    enacted laws providing for a state-conferred exclusive franchise for electric utility
    territories. There remains a role for competition even in retail electric services, within the
    confines of the state’s franchise and regulatory laws. And at wholesale—in the extensive
    purchasing, selling, and exchanging of power—there is no natural or governmentally
    conferred monopoly and one finds the kind of brisk competition familiar to other
    industries.
    Given the vast cost of power facilities and the economic and strategic importance
    of the most efficient possible allocation of resources in the production of electric power,
    there is enormous value in commerce among utilities, permitting the low-cost producer to
    provide needed power. In California, the three private utilities—SCE, PG&E, and
    SDG&E—have long recognized that value, forming the California Power Pool, engaging
    in numerous sales and exchanges of energy and capacity both within and outside the
    pool, and developing elaborate reserve-sharing relationships to reciprocally supplement
    the reliability of their respective systems.
    The California electric power industry has historically been dominated by the
    three private utilities. There is one large municipal utility, the City of Los Angeles; the
    remaining electric utilities are substantially smaller municipalities, and each has
    historically depended to a large degree on either Edison or PG&E for its power,16
    although some have recently begun developing their own generating resources to meet
    part of their loads. In recent years, non-utility independent power producers have, with
    the assistance of the Public Utilities Regulatory Policy Act (PURPA),17 been able to play
    a role in the production and sale of electricity. Out-of-state utilities are another major
    source of power for California utilities.
    16
    The exceptions are Burbank and Glendale, which operate within the control area of LADWP
    and rely more on LA than on Edison.

    VI.		   THE HISTORIC ANTITRUST PROBLEM IN THE CALIFORNIA
    WHOLESALE POWER MARKETS
    The history of the investor-owned utilities’ dominance of the California power
    markets has been well chronicled, by the federal enforcement agencies and others.18 In
    1971 the U.S. Department of Justice found a history of anticompetitive conduct by SCE
    and recommended that the Atomic Energy Commission hold an antitrust hearing before
    licensing San Onofre Units 2 and 3. (36 Fed. Reg. 17886 (1971).) The advice letter noted
    that Edison has “pursued a policy of acquiring the systems of its competitors,” has “in the
    past acted to block efforts of its all-requirements wholesale customers to receive bulk-
    power through alternative sources through wheeling over Edison’s transmission
    facilities,” specifically noting the difficulties of the Anza Electric Cooperative, the City
    of Colton, and the Cities of Anaheim and Riverside, and has used provisions in its
    agreements with wholesale customers “forbidding the operation of the customer’s system
    in parallel with Edison’s and the provisions precluding the resale or use outside of the
    customer’s system of the purchased power.” (Id., pp. 3, 4-6, 10.) The department
    concluded that “consideration of the totality of Edison’s conduct makes it actually
    impossible to conclude that the applicant’s activities under this license, if granted, would
    not maintain a situation inconsistent with the antitrust laws.”
    Despite the long attention of federal regulators to the competitive conditions in the
    California electricity markets, the problems persist. Notwithstanding Edison’s
    commitment to a series of conditions on transmission (known as the SONGS
    Commitments), in 1987 an FERC administrative law judge found SCE continues to
    pursue anticompetitive transmission practices. (Southern California Edison Co. (1987) 39
    F.E.R.C. ¶63,045 (finding SCE had failed to offer the City of Vernon transmission on just
    and reasonable conditions, imposing curtailment terms that reserved to Edison “discretion
    . . . to . . . trigger a curtailment . . . in an arbitrary or unfair manner,” rendering “Edison’s
    transmission offer . . . an empty gesture.”).19)

    VII.    ANALYSIS OF THE COMPETITIVE EFFECTS OF THIS MERGER
    To take advantage of the wholesale commerce among electric utilities, firms must
    have access to markets in which the components of electric power are marketed. They
    require transmission between power sources and loads, access to prospective buyers and
    sellers, and generating resources and contractual arrangements to ensure prudent reserve
    margins. This has led the courts to a recurring pattern of market definitions, based on a
    functional breakdown of the electric utility industry. In wholesale electricity, the courts
    have identified separate markets for at least three different functions: generation of
    power, transmission of power between generating facilities and loads, and distribution to
    customers. (See generally Fairman & Scott, Competition in the Electric Utility Industry
    (1977) 28 Hast.L.J. 1159; Meeks, Concentration in the Electric Power Industry: The
    Impact of Antitrust Policy (1972) 72 Colum.L.Rev. 64.)
    A.      TRANSMISSION
    1.      Horizontal Analysis
    a.      Market definition
    (1)      Product market
    The experts’ disagreement over transmission begins with the question whether it
    represents a separate product market. On one side are those who identify transmission as
    a separate product. (E.g., Owen FERC Direct Testim. at 112-178; Exh. 10,200 at II-6, ch.
    III.) Others dispute the claim, arguing that the only product that matters is delivered
    power, combining the capacity, energy, and their delivery. (Bower FERC Rebuttal
    Testim. at 5; Pace FERC Direct Testim. at 14-29; Joskow FERC Direct Testim. at 27-43.)
    It is worth noting that virtually every reported case in this industry recognizes the
    importance of the separate transmission market to a proper antitrust analysis of wholesale
    electricity markets.20
    20
    E.g., Otter Tail Power Co. v. United States (1973) 
    410 U.S. 366
    (electric utility having
    “ ‘strategic dominance in the transmission of power in most of its service area’ and that use[s] this
    dominance . . . ‘to destroy threatened competition” ’ violates section 2 of the Sherman Act); Conway
    Corporation v. Federal Power Commission (D.C. Cir. 1975) 
    510 F.2d 1264
    (dominant utility “ ‘can
    virtually control the performance of [neighboring] municipal system through its control over the
    wholesale price of power. . . . Such control by selling systems is probably very common and very
    effective, primarily because of the almost universal control over transmission by the dominant selling
    system in an area. This kind of “unfair” competition is usually directed at municipals and cooperatives but
    also occasionally at small private systems, particularly when the seller is seeking to absorb the smaller
    system by merger’ ” quoting Meeks, Concentration in the Electric Power Industry: The Impact of
    Antitrust 
    Policy, supra
    , 72 Colum.L.Rev. 64); Utah Power & Light (1988) 45 F.E.R.C. ¶ 61,095.
    20
    90-507
    Some of the dispute among the experts revolves around the way in which
    transactions are characterized. A former SDG&E scheduling supervisor points out that
    SDG&E’s revenues from interruptible transmission service (i.e., wheeling) amounted to
    only $28,000 in 1987 and 1988. (Gaebe FERC Direct Testim. at 40.) On the other hand,
    the record is replete with examples of SDG&E “brokering” power by purchase and
    immediate resale.21 The fact that, in some sense, title to the power passed to SDG&E is
    immaterial to the true character of these transactions. The value SDG&E was adding to
    the power, and the service for which it was being compensated, was unquestionably
    transmission.22
    The fundamental point for purposes of determining whether transmission is a
    separate product is that transmission services can be and routinely are offered for sale
    separately from power. (Exh. 10,200 at II-6; Roach FERC Direct Testim. at 30.)
    Transmission service is essential to the ability of firms to gain access to all other power
    product markets simply because one cannot deliver power without transmission. Thus, as
    courts have routinely recognized, transmission can and should be treated as a separate
    product market.
    (2)    Geographic Market
    Virtually all of the witnesses to discuss the relevant geographic markets for
    transmission service agree, at a minimum, that it is appropriate to separate transmission
    between California and the Pacific Northwest and transmission between California and
    the Southwest.23 (Owen FERC Direct Testim. at 167-72; Roach FERC Direct Testim. at
    33-38; Pace FERC Direct Testim. at 30-72; cf. Marcus PUC Direct, Table 1.) The reason
    is basic—transmission between California and the Southwest is simply not a substitute
    for transmission between California and the Pacific Northwest. (Roach FERC Direct
    Testim. at 34; Exh. 10,200 at II-13 to II-16.) There are limited connections between the
    21
    Owen FERC Direct Testim. at 140–45 ; Mays Depo. at 31–33.
    22
    In a sense, SDG&E was providing two services: actual delivery over transmission lines and
    “access” to the market. Where, as the testimony suggests (Mays Depo. at 63–64; Pace FERC Rebuttal
    Testim. at 31–33), SDG&E controllers were actually providing expertise in wholesale power marketing, it
    may make sense to distinguish between actual delivery and market access. But historically, the only
    reason why prospective purchasers lacked access was that they lacked a transmission path.
    23
    Some witnesses have suggested other relevant transmission markets, such as between the
    Pacific Northwest and the Southwest, or transmission across Edison’s service territory. (E.g., Owen
    FERC Direct Testim. at 174–178.) By not addressing these markets here, we do not suggest that those
    analyses are incorrect. We simply address those markets about which there seems to be little disagreement
    as to the appropriateness of concluding that they are relevant for purposes of this case and where serious
    adverse consequences are threatened by the proposed merger.
    21
    90-507
    Pacific Northwest and the Southwest, so the regions are separated by the lack of
    transmission paths. (Id., at II-16.) Moreover, the cost for transmission service from the
    two regions varies significantly due to differing levels of transmission losses. (Id., at II­
    14 to II-15.) These factors compel the conclusion that there are separate geographic
    markets for transmission service between California and the Pacific Northwest and the
    Southwest. (Id., at II-16.)
    b.      Market power
    (1)    California/Southwest. An analysis of total capacity24 over transmission lines
    connecting California and the Southwest shows that concentration as measured by HHIs
    is and will remain highly concentrated even without the merger. In the years 1989
    through 2000, the HHIs for transmission rights will average 2911 without the merger.
    (Owen FERC Direct Testim., Exh. BMO-3, Sched. 6.) Post-merger HHIs will increase to
    an average of 3604 over that same period. (Ibid.) This represents an average increase in
    the HHIs of 693. (Ibid.) These figures indicate that the merger would unlawfully increase
    concentration in this market.
    A portion of each utility’s transmission capacity is typically committed to
    transmission of power from a firm power resource—either a power plant or a point at
    which the utility has a contractual right to receive power from another utility. To the
    extent that such commitments preclude use of the capacity for other purposes (whether
    wheeling for others or transmission for the utility itself from other resources), the
    committed capacity has a different competitive significance than capacity not so
    committed. Of course, even “committed” transmission capacity becomes free, for
    example when the resource to which it is committed is not generating. Nevertheless, it
    makes sense to talk about total transmission capacity and, separately, about “available”
    capacity—that capacity not committed to any firm resource. Such capacity is particularly
    important in the vertical analysis, when assessing the transmission available to obtain
    bulk power.
    When limited to “available” capacity, the market is even more highly concentrated
    as a result of the proposed merger than when examining all transmission capacity.
    (Marcus PUC Direct Testim., Tab. I.) Transmission available for purchases from the
    Southwest is highly concentrated today, and the concentration will increase greatly every
    year over the next decade due to the merger. (Ibid.) For example, non-firm transfer
    capability from the Southwest in 1991 averages 3378 MW, with an HHI of 2300 without
    the merger. The proposed merger would increase the HHI by 678, to 2978. Even larger
    increases are observed in later years. (See Table 2.)
    24
    This includes both firm and non-firm contractual entitlements, as well as ownership of lines.

    Note: All figures reflect average of all days and hours.
    Thus, measured both by absolute control of transmission capacity and by available
    supply of uncommitted capacity, the proposed merger can only be described as posing
    severe threats to competition in the market for transmission between California and the
    Southwest, and in the markets depending on that capacity.
    (2)   California/Northwest. An analysis of transmission capacity from the
    Northwest into California reveals a similar pattern of high concentrations—though less
    highly concentrated than the extremes found in the California/Southwest market. (See
    Table 3.)

    Edison claims the merger will create additional transmission capacity for other
    utilities. (E.g., Pace FERC at 32.) However, taking into account the additional capacity
    23
    90-507
    Edison projects, and assuming the new capacity goes to parties other than SCE or
    SDG&E, the merger continues to have adverse effects on competition in this market.
    With the Edison proviso, the merger increases HHIs from already highly concentrated
    levels by amounts ranging from 62 to 110 points, exceeding both USDOJ and state
    enforcement guidelines. (Owen FERC Testim., Exh. BMO–3, Sched. 12.)
    SDG&E has historically, and will continue to have, entitlements over the Pacific
    Intertie equalling approximately 4% of the total line capacity to the Northwest available
    to all utilities. (Owen FERC Direct Testim. at 169.) SDG&E has consistently utilized
    100% of its Intertie capacity during the peak hours since 1985. (Gaebe Exh. GPG–6,
    FERC Exh. 175.) Edison’s share of the transmission capacity to the Northwest will range
    from 25.2% to 29.3% between 1989 and the year 2000. (Owen FERC Direct Testim. at
    169.) SDG&E will control from 4% to 4.3% during the same time. (Ibid.)
    Thus, over the next decade, the merger will increase concentration in this market
    as well. Given the strategic importance of transmission in enabling firms to participate in
    bulk power transactions, and given SDG&E’s emergence as a firm more and more
    willing to act as a broker in transactions between other utilities who do not have access to
    transmission paths (Mays Depo. at 44–46), the loss of SDG&E as an independent source
    of transmission is even more significant.
    2.		   Vertical Analysis
    The foregoing evaluation of the horizontal effects on the transmission markets
    revealed substantial adverse effects on competition from the merger. The evidence
    discloses even more dramatic competitive harm in the vertical effects of the merger.
    Edison competes with other utilities as both a buyer and a seller of bulk power.
    Because transmission determines a firm’s access to the markets for power, Edison’s
    control of transmission raises concerns about the use of that control to exclude competing
    buyers and sellers from bulk power markets.
    And, in fact, the record demonstrates that SCE has used its control over
    transmission to gain advantages in other markets. For example:
    ■		    A former dispatcher for SCE testifies that when he was employed by
    Edison the standing procedure was whenever Anaheim requested
    transmission service SCE would buy and schedule as much power as
    possible over the line in order to refuse the transmission; only if they
    couldn’t purchase enough energy to fill the line would Anaheim get the
    service. He also describes how SCE would try to buy economy energy to
    24
    90-507
    interrupt cities’ nonfirm service, knowing that would make other utilities
    reluctant to deal with the cities. (McCann FERC Direct Testim. at 21–22 &
    29–30.)
    ■		     SCE prevented Riverside from selling its excess energy to Azusa, Banning,
    and Colton and terminated transmission service to Riverside for alleged
    technical reasons. (Greenwalt FERC Direct Testim. at 17–19.)
    ■		     SCE refused to provide SDG&E transmission service northward that would
    have enabled SDG&E to sell power to Vernon and other Southern Cities—
    despite an internal SCE document showing transmission capacity existed.
    (Russell FERC Direct Testim. at 68–74.) SCE falsely claimed line-loading
    problems to prevent Nevada Power from selling power to Vernon. (Id., at
    100–101.) SCE refused to give timely agreement to a request for wheeling
    to Southern Cities from Arizona Power’s Cholla plant, then obtained the
    power itself. (Id., at 116.) SCE refuses to schedule nonfirm transmission
    more than an hour in advance, precluding Southern Cities from getting
    Northwest power, which is scheduled a day in advance. (Id., at 133–35.)
    ■		     SCE has consistently refused, since 1985, to provide Arizona Electric
    Power Cooperative (AEPCO) with transmission service of more than 10
    MW to one of its customers, the Anza Electric Cooperative, leaving Anza
    in the position of serving its growing needs even though AEPCO is willing
    to provide the power for those needs. (Rein FERC Direct Testim. at 8–18.)
    These are precisely the kinds of exclusionary practices that the antitrust laws prohibit.25
    Edison has not offered convincing evidence to rebut these claims and simply fails
    to respond at all to others. Rather, it argues that the merger will make things no worse. In
    essence, it claims that SDG&E today does not provide an independent transmission path
    between any of the entities complaining of SCE practices and outside markets; in each
    case, even if SDG&E wished to provide transmission service to one of the utilities, it
    could not do so without enlisting the aid of SCE for some portion of the delivery.
    25
    The relevance of these exclusionary practices lies in what they show about the potential vertical
    effects of the merger. SCE’s acquisition of SDG&E’s transmission grid represents a horizontal
    consolidation. However, the evidence of SCE’s use of transmission to exclude competition in other
    markets is probative of whether the merger will increase the opportunity for abuse of market power in
    transmission to gain advantage in other markets, a vertical effect that must be considered.
    25
    90-507
    Because Edison is correct that there does not today exist a complete long-term
    transmission path between SDG&E and any of the utilities SCE encircles, this claim
    represents a substantial defense. But the claim ignores the realities of the current market
    and the potential for a more open market in the future.
    While SCE’s cooperation can be withheld from transmission requests, under
    existing SCE commitments the company must tender a reason for doing so. As noted
    above, SCE has been willing to devise such an excuse from time to time. But the ability
    to construct such a claim is not limitless, and the less SCE cooperation is required the
    more likely the transaction can be consummated. The availability of capacity on a short
    link is easier to verify and less susceptible to manipulation than the availability of
    capacity for long-distance transmission across the grid—the extent of SCE cooperation
    that would be required after the merger.
    Furthermore, to the extent that SCE is constrained by either the potential of legal
    action or the pressures of opinion in the industry, the constraint depends on the existence
    of a party positioned and equipped to detect and verify the sham claim. As a large,
    sophisticated utility with a demonstrated interest in a vibrant commerce in wholesale
    power, SDG&E represents the best such party. Were SCE to absorb SDG&E, SCE would
    necessarily be less constrained in refusing to make transmission available to other
    utilities.
    And it would be a mistake to assess the competitive effects of a merger solely on
    the basis of the existing configuration of the transmission grids. Each utility’s
    transmission system is dynamic, and the potential for expansion (either by SDG&E or by
    another utility reaching out to SDG&E) cannot be disregarded. A merger that forecloses
    such possibilities in perpetuity certainly adversely affects competition.
    It would also be inappropriate to assume that the kinds of exclusionary practices
    engaged in by SCE will forever escape effective enforcement. If access over a relatively
    short link can be shown to be an impediment to open competition, a court or
    administrative agency may well be able to enter an appropriate order to remedy the
    problem. The court’s or agency’s ability to fashion and enforce an effective order
    regarding the entire integrated transmission system of a combined SCE-SDG&E would
    necessarily be much more doubtful.
    B.     BULK POWER
    1.     Long-Term, Firm Power
    a.     Market definition
    26
    90-507
    (1)    Product market
    Firm power is power sold with a charge for capacity (commonly called a “demand
    charge”). This is power committed to a particular purchaser. (Exh. 10,200, p. II–9.) Long-
    term firm power is defined as power which is committed for a period longer than one
    year. (Roach FERC Direct Testim. p. 21.) Firm power is a separate product market
    because non-firm sales are not an adequate substitute for firm sales. (Ibid.) As Roach
    notes:
    “. . . a utility cannot rely on non-firm sales to fill its capacity needs. Non-
    firm sales are made to take advantage of lower cost sources of energy. Firm
    sales are used to meet a utility’s capacity needs, and take advantage of
    lower cost sources of both energy and capacity.” (Ibid., emphasis in
    original.)
    Within the product market called “firm power,” one can distinguish at least three
    separate sub-markets: Northwest power, Southwest power, and California power. While
    their names suggest that they are geographic sub-markets, they are in fact distinguished
    by the unique characteristics of the power produced in the three regions. Northwest
    power, when it is available, is typically the lowest-cost power available. (FERC
    Exh. 1160.) However, the supply of Northwest power is seasonal, with the greatest
    supply obtainable at different times of year than power from other regions. (Ibid.)
    As Taylor states:
    “In most years, the Pacific Northwest has energy that is surplus to the
    region’s needs, and California is the primary market for this surplus. There
    is seasonal diversity between the Pacific Northwest, which is winter
    peaking, and southern California, which is summer peaking. This diversity
    makes the Pacific Northwest a source of capacity to supply Southern
    California summer peak loads. There is not the same seasonal diversity
    between southern California and the Inland Southwest, which also is
    summer peaking.” (Taylor FERC Direct Testim., pp. 55–57.)
    SCE itself pays careful attention to these differences in its own resource planning,
    separately planning for power from the Northwest, Southwest, and California because of
    the different price and availability characteristics of power from the three regions. (See
    FERC Exh. 1160.)
    (2)    Geographic market
    27
    90-507
    SDG&E and Edison both purchase and sell firm power over the entire area of the
    Western Systems Coordinating Council (“WSCC”) member systems, an area comprising
    the Western United States, portions of western Canada and northern Mexico (Baja).
    (Taylor FERC Direct Testim. at 55.) However, transportation constraints define separate
    markets for power in the Northwest, the Southwest, and California. As the Division of
    Ratepayer Advocates (DRA) convincingly argues:
    “The connection between utilities in the Southwest and Northwest is largely
    via California, and through Edison and SDG&E in particular. If the merged
    firm acted to depress prices for purchase of wholesale electricity from the
    Southwest, the alternative market for this power would be utilities to the
    North. However, access to these utilities is largely via transmission lines of
    the merged firm. It is unlikely that the merged firm would grant unlimited
    access to utilities in the Southwest that are seeking alternative customers
    for their bulk power. A similar argument applies to transactions between
    utilities in the Northwest and other buyers to the South.” (Exh. 10,200 at II–
    16.)
    Accordingly, it is appropriate to treat the Pacific Northwest and the Southwest as distinct
    geographic markets for the purchase of bulk power, whether long-term or short-term.
    b.      Market power
    Whether the merger will confer market power on the merged company can be
    analyzed separately for the purchase and sale of each form of firm power in the
    Southwest and the Northwest geographic markets. However, since neither SCE nor
    SDG&E sell significant amounts of firm power to the Northwest and little, if any, firm
    power is sold from the Northwest, the merger will have little effect in that geographic
    market for firm power purchases or sales. (Exh. 10,200, Tables II-19 & II-21.) Likewise,
    SDG&E has sold almost no firm power in the Southwest market (Exh. 10,200 at II-56),
    and there is no evidence that SDG&E is likely to become a significant seller of long-term
    firm power in that market.26 Therefore, we limit our examination of the firm-power
    markets to purchases from the Southwest.
    26
    DRA calculated HHI for these respective markets using figures that were derived from FERC
    form 1 for each utility in the markets. Their analysis excluded sales characterized as “requirements
    transactions” because such power is not made available as surplus to other market participants. Also
    excluded were Bonneville Power Administration sales to public entities because of the lower preferential
    rates charged to such entities and because this power is not available to all market participants. Colorado
    River Storage Project power was not included because of its very low price. Finally, sales by three large
    public utility districts in the Northwest were not included because their sales were only available to
    contiguous utilities. (Exh. 10,200 at II–51–52.)
    28
    90-507
    Both SCE and SDG&E buy significant amounts of firm power from the
    Southwest. From 1985 to 1988, the two companies purchased on average more than 36%
    of all firm power sold in the Southwest.27 (Exh. 10,200, Table II-15.) In 1988, they
    accounted for more than 45% of the firm power purchases in the Southwest. (Ibid.) Based
    on 1988 sales, the pre-merger HHI for purchases of firm power from the Southwest was
    1456. (Ibid.) The merger will increase the HHI by 1014 to 2470. (See Table 4.) These
    figures far exceed those considered by both federal and state enforcement officials to
    constitute a violation of the Clayton Act.

    DRA acknowledges that these figures are cause for at least “moderate concern”
    over the increase in market power for firm purchases in the Southwest. (Exh.10,200 at II–
    54.) However, DRA suggests that the high elasticity of firm power supply, coupled with
    the “option of providing power for own use as an alternative to selling firm power in the
    wholesale market,” should temper such concern. (Ibid.) We cannot agree.
    While there is some evidence suggesting high elasticity in the supply of firm
    power, any increase in SCE’s market power caused by the merger remains a concern.
    28
    27
    The DRA calculations appear to be based on sale transactions it could identify as firm,
    excluding certain sales made to requirements customers of the reporting utilities. Thus, DRA did not
    include power used by the selling utilities to serve their own long-term firm loads for purposes of
    calculating concentration figures. (Exh. 10,200 at II–50 to II–51.)
    28
    The principal evidence is the success of PURPA in developing new generation sources at rates
    unanticipated when the statute was enacted. However, there is no assurance that that success will continue
    in light of proposed changes to the rules governing utilities’ obligations to buy the capacity from new
    sources. Moreover, the long lead times necessary for development of new generation sources, together
    with the environmental difficulties associated with new plant siting issues, particularly for SCE and
    SDG&E, suggests that they will continue to be significant buyers of firm capacity.
    29
    90-507
    Even if sellers can, in the long term, adjust to exercises of market power, the immediate
    effects unquestionably constitute an adverse effect on competition.
    Second, we do not agree that the option of providing power for one’s own use
    could minimize the merger’s effect of increasing the merged company’s purchaser
    market power. The ability to find alternative sources of power, including self-generation,
    may ameliorate the effects on other purchasers,29 but the issue in analyzing purchaser
    market power is whether the merger will adversely affect the sellers. Accordingly, we
    remain convinced that the evidence demonstrates the merger will have adverse effects on
    competition in the market for the purchase of firm power in the Southwest.
    2.      Short-term Bulk Power
    a.      Market definition
    (1)      Product market
    Electric utilities buy and sell a variety of short-term power products that they use
    to meet their loads. These products include non-firm economy energy, short-term firm
    capacity and energy, unit commitments, and exchange agreements.30 Effective
    management of short-term purchases, mixed with a utility’s own generation and long-
    term firm purchases, provide an efficient method of meeting the utility’s load at the
    lowest possible cost.31 (Mays Depo. at 21-22.) These products can be viewed as
    comprising a single product market we will call short-term bulk power. (Mays Depo at
    29
    If alternative supplies exist, they would be expected to temper SCE’s increased market power
    as a seller, which would be relevant to determining whether the merger has adverse effects on competition
    in markets where SCE and SDG&E sell (presumably Southern California). As noted above, however, we
    do not find the merger to have an adverse effect on those markets.
    30
    . Exchange agreements are barter arrangements for power—capacity, energy, or both. The
    agreements can be creatively structured to provide for complementary needs of the exchanging utilities.
    For example, summer peaking utilities such as SDG&E can exchange their off-peak winter capacity and
    energy with winter-peaking utilities such as Portland General Electric (PGE) for summer peaking
    capacity and energy that PGE has in abundance during its lower peaking spring and summer months due
    to the snow melt. (Gaebe FERC Direct Testim. at 5174.)
    31
    Most long-term capacity and energy purchase contracts permit the buying utility not to take
    energy if it so chooses. (Gaebe FERC Direct Testim. at 5147.) So the buying utility always has the option
    of purchasing short-term products to substitute for energy it could demand under one of its long-term
    contracts if the economics of a particular transaction make it desireable to do so. Likewise, utilities can
    choose to buy short-term products in lieu of turning on one of their own generating units when the
    economics of fuel prices and availability of short-term power make it economical to buy rather than burn,
    for example, fuel oil.
    30
    90-507
    17.) Effective participation in the short-term bulk power market creates opportunities for
    utilities to sell short-term bulk power products to other utilities, producing revenue to
    reduce their own rates and to increase profits for their shareholders. (Mays Depo. at 22,
    46; Boettcher Depo. at 67-68.)
    Some utilities, including SDG&E, provide for substantial portions of their load by
    purchasing these short-term products. Many utilities, also including SDG&E, sell short-
    term bulk power profitably to other utilities. (Mays Depo. at 44; Boettcher Depo. at 76.)
    Recent developments in the Western United States, including initiating service over
    SDG&E’s Southwest Power Link (SWPL) and the emergence of the Western Systems
    Power Pool (WSPP), have effectively created a burgeoning marketplace for short-term
    bulk power transactions. (Mays Depo. at 48, 81.) Since most utilities in the Western
    United States buy and sell short-term bulk power and participate in the WSPP, the
    SCE/SDG&E merger must be analyzed in terms of its impact on this developing market.32
    Again, the different price and supply characteristics of power in the Northwest, the
    Southwest, and California require us to distinguish between power produced in the three
    regions. Edison has noted this difference particularly with respect to economy energy,
    one form of short-term bulk-power:
    “The forecast quantity of economy energy is a function of transmission
    capability and availability of cost-effective economy energy from each of
    the three markets. As can be expected, [Northwest] and California economy
    energy availability is highly weather-dependent, while [Southwest]
    availability is primarily a function of ‘excess’ installed capacity compared
    to loads in the region.
    “. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
    “Historically, energy from the [Northwest] is abundantly available only
    during the spring runoff period of April through June.
    “. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
    32
    Because SDG&E’s participation in bulk power markets as a buyer and seller to any significant
    degree is a relatively recent phenomenon, coinciding with the advent of SWPL and the WSPP, the merger
    must also be analyzed for its impact on the potential for competition in the future. Historical data is
    relevant to this analysis and suggests that the merger raises competitive concerns in some short-term bulk
    power geographic markets as discussed below. However, the potential for competition in short-term bulk
    power markets in the future is probably best analyzed by examining available transmission to determine
    the future ability of firms to engage in short-term bulk power transactions.
    31
    90-507
    “Historically, economy energy purchases from the [Northwest] region
    have been favorably priced in comparison to [Southwest] and California
    markets due to predominantly hydroelectric baseload resources.”
    (Exh. 1160, pp. 3–70 to 3–71.)
    (2)     Geographic market
    A firm’s ability to buy or sell short-term bulk power to other utilities depends not
    only on the willingness of other utilities to purchase or sell power, but also on a number
    of other factors. Access to buyers and sellers via transmission paths is a principal
    constraint on the ability to participate in the short-term bulk power markets. (Exh. 10,200
    at II-5 to II-8.) Another important constraint is the seasonal diversity of supply and
    demand that largely defines the geographic areas where there are buyers and sellers at
    any given time. These two factors play a large, if not dispositive, role in defining the
    geographic markets in which buyers and sellers compete.
    We conclude that, for both purchaser and seller short-term bulk power markets,
    differences between the firms that can buy and sell at various times of the year provide
    clear definition to two distinct geographic markets for transactions with California
    utilities, the Pacific Northwest, and the Southwest. These geographic markets for short-
    term bulk power are distinct because, in large measure, the utilities in the Pacific
    Northwest that can engage in transactions with utilities in California cannot buy from or
    sell to utilities in the Southwest. (Exh. 10,200 at II-13 to II-16.) Likewise, utilities in the
    Southwest that can engage in transactions with utilities in California cannot buy from or
    sell to utilities in the Pacific Northwest.33 Moreover, on the average, when short-term bulk
    power is available from the Pacific Northwest, it tends to be less available from the
    Southwest because of the seasonal diversity between the peak loads of those two regions.
    The reverse is also true. (Russell FERC Direct Testim. at 33-38; Mays Depo. at 35.)
    Thus, the competitive effects of the proposed merger must be analyzed in terms of the
    merger’s effect on the ability of firms in California to sell to and buy from utilities in the
    Pacific Northwest, as well as its effect on the ability of firms in California to transact
    business with utilities in the Southwest.
    b.      Market power
    (1)     Southwest short-term bulk power
    33
    This is true because there is very limited transmission access between the Southwest and the
    Pacific Northwest. (Exh. 10,200 at II–15 to II–16.) On the other hand, there are major interties between
    both the Southwest and California and the Pacific Northwest and California. (Ibid.)
    32
    90-507
    (a)     Seller market power
    (i)    In the Southwest. Measured by historical sales in the Southwest, the role of
    SCE and SDG&E as sellers of short-term bulk power has not been large. (Exh. 10,200 at
    II–39 to II–41.) This has been true mainly because of the recent surplus in capacity in the
    Southwest. (Gaebe FERC Direct Testim. at 5209–5210.) Accordingly, the significant
    impact of the merger will be on its removal of SDG&E as a potential supplier in that
    market, for which there is concrete evidence. SDG&E has, by its own description,
    developed an “aggressive” attitude towards pursuing sales that can reduce its ratepayers
    costs and produce revenue for its shareholders. (Mays Depo. at 43–46.) Coupled with a
    corporate “culture” of opportunistically competing for sales (Mays Depo. at 76), SDG&E
    represents a significant source of potential competition in the market for short-term bulk
    power sales in the Southwest. The merger would eliminate that competition.
    (ii)   In California. However, Southwest non-firm power is economically
    attractive for California utilities. Because we have found that the proposed merger will
    permit SCE to control access to such power beyond, it would perforce also give SCE
    market power over sale of Southwest power in California.
    (b)     Buyer market power
    Evidence concerning the effects of the proposed merger on the buying side of the
    short-term bulk power market between the Southwest and California demonstrates that
    substantial adverse effects on competition are likely. DRA has shown that, based on
    recent figures for non-firm energy purchases in the Southwest market as they define it,34
    the merger will increase concentration as measured by the increase in HHI levels. (Exh.
    10,200 at II-36 to II-39.) Figures for 1988, for example, show that the merger will
    increase the HHI by 704, to 1741. The 1988 figure calculated by DRA does not appear to
    be idiosyncratic in light of the trend data DRA presents. That data calculated the effect of
    the proposed merger for the years 1985, 1987 and 1988 showing comparable results in
    each year.
    34
    DRA defines the Southwest market to include all purchases and sales between the utilities it
    has included in the Southwest market. (Exh. 10,200 at II–29 to II–36.) DRA also describes firm and non-
    firm product markets within the Southwest market. (Id., p. II–29.) The DRA analysis includes some short-
    term firm sales in the non-firm or economy energy market; it may also include some short-term firm sales
    in the firm market for purposes of its analysis. (Ibid.) Moreover, DRA makes no attempt to account for
    the seasonal variations in buying and selling, and thus understates the competitive impact of the merger in
    both its buyer market power and seller market power analyses. (Id., p. II–36 to II–41.) Nonetheless, the
    DRA’s buyer market analysis for the firm and non-firm markets in the Southwest suggests serious
    competitive harm from this merger, (cf. Exh. 10,200 at II–36 to II–39 with II–52 to II–54), especially in
    light of its failure to account for the importance of seasonal diversity in the non-firm market.
    33
    90-507
    Thus, the merger will increase concentration in the short-term bulk power market.
    Moreover, because DRA analyzed market shares without accounting for seasonal
    variations in purchases, its figures likely understate the effects of the merger for times
    when SCE and SDG&E are most likely competing to buy Southwest short-term bulk
    power.

    The evidence of increasing concentration in the market for “available”
    transmission between California and the Southwest in the coming years suggests that the
    trend will be toward increasing concentration in this market as well. The concentration in
    the non-firm power market, already substantially greater than permitted by the antitrust
    laws, appears even more serious against the backdrop of a market for transmission that is
    increasingly concentrated in the hands of Edison.
    (2)    Pacific Northwest non-firm bulk power
    (a)    Seller market power
    While SDG&E has historically made a substantial share of its bulk power sales to
    the Northwest (Pace Workpapers Supporting Response to Surrebuttal Testim. of Owen,
    March 26, 1990 (“Pace Workpapers”) at 13–14), there is no evidence that the volumes
    sold by SDG&E and Edison into the Northwest are sufficient to have any effect on
    competition in this market.
    (b)    Buyer market power
    From 1984 through 1988, SDG&E purchased almost 2 billion kWh of economy
    energy from the Northwest, 20% of its economy energy purchases. (FERC Exh. 1203 at
    II–42.) More recent data confirm the existence of substantial continuing purchases. (Ibid.)
    34
    90-507
    The concentration figures that have been calculated thus far are ambiguous about
    the effects of the merger. DRA computes HHIs in the “moderately concentrated” range
    (1400–1600 post-merger for the 1985–88 period), with the merger responsible for
    increases ranging from the negligible to substantial. (Exh. 10,200, Tab. II–10.) From this,
    DRA concludes that “there are some potential buyer market power concerns.” (Id., p. II–
    48.)
    We agree with DRA that there is a basis for concern in these figures, particularly
    in light of the fact that the merger would substantially increase concentration for
    transmission to the Northwest. It may well be that the effects of this merger are masked
    by the fact that the DRA figures are aggregated on an annual basis. California utilities’
    purchases are typically seasonal (reflecting the different time of year of maximum load
    and hydroelectric generation). The merger may confer buyer market power on a seasonal
    basis. But at this point, that is merely conjecture; all that can be said on the basis of the
    present record is that which DRA says, that the evidence properly gives rise to some
    concerns about competitive effects.
    (3)     The emerging short-term bulk power markets
    In 1987, the FERC approved operations under an experimental pooling agreement
    known as the Western Systems Power Pool (WSPP).35 (FERC Exh. 1203 at II-12.) The
    WSPP has become the largest power pool in the nation. (Ibid.) SDG&E has made
    economy energy purchases and sales, as well as transmission service arrangements under
    the WSPP, since its inception, resulting in lower operating costs. (FERC Exh. 1203 at II­
    14.) SDG&E has, as a result of a “corporate culture” developed in recent years of
    viewing itself as an aggressive “energy management company,” come to view the WSPP
    as a marketplace for transactions which can both lower its ratepayers costs and improve
    its shareholders profits. (Mays Depo. at 46.) As experience by SDG&E and other utilities
    has improved, SDG&E has developed a role of “middleman” in making economic
    arrangements between utilities under the WSPP. (Mays Depo. at 63.) Other utilities,
    particularly municipal utilities with limited transmission access such as MSR and TID,
    have begun to look to SDG&E as a broker for power purchases and sales under the
    WSPP, a role which SDG&E has willingly filled. (Mays Depo. at 62-65.) The SDG&E
    employee responsible for supervising SDG&E’s short-term purchases and sales on a day-
    to-day basis from December 1987 through December 1989 has described SDG&E’s role
    as follows:
    35
    Originally, the WSPP was approved as a two-year experiment in market based pricing, but the
    agreement has been extended for at least two more years and SDG&E supports its further extension.
    (FERC Exh 1203 at II–12 to II–13; Gaebe FERC Direct Testim. at 5228.)
    35
    90-507
    “But [municipal utilities are] new to the marketplace, and don’t have all the
    contracts in place we do. They don’t have the schedulers with the
    knowledge ours do of the marketplace. And there seems to be a market
    almost for a service—it’s sort of like training wheels on a bike—that we
    can provide for people in that category, of helping them. And it takes quite
    a bit of time and effort.
    “We’re not getting the greatest profit out of it. It takes time. In fact, we
    added a third scheduler because we were doing this. We have a salary
    involved there that helps us support the additional sales and purchases that
    we make.
    “And we have—we seem to have recently stepped in and filled a void in
    that marketplace of assistance.” (Mays Depo. at 63–64.)
    This market may well grow under the WSPP (id., at 76), and it is certain to
    continue in some form. To the extent it does, SDG&E will continue to play an aggressive
    role in the market whatever form it takes. (Id., at 76–77.) One result of SDG&E’s
    participation in this burgeoning market has been the dramatic growth in SDG&E’s sales
    since 1986. (Gaebe Testim., GPG–1, FERC Exh. 181; Mays Depo. at 80–81.)
    SDG&E’s emergence as an aggressive competitor in this emerging market raises
    special concerns that further demonstrate the merger’s adverse effects on competition.
    C.     RETAIL ELECTRIC SERVICE
    Because retail electric service is typically provided through exclusive utility
    franchises, most customers do not have the day-to-day option of buying their electricity
    from the utility of their choice. Yet utilities are not free of competitive pressures, even in
    retail service. There is occasionally actual competition for customers, either in new
    territories, on the occasions when franchises become open to competition, and when
    customers choose to take new business to one territory or another. Perhaps most
    important in the regulated environment of retail electricity service, regulatory decisions
    are made in part by comparison of similarly situated utilities. (See Taylor FERC Direct
    Testim., pp. 33–35; Owen FERC Direct Testim., pp. 178–79.) Economists have identified
    these various forms of competition as “franchise,” “fringe,” and “yardstick” competition.
    1.     Yardstick Competition
    “Yardstick competition” refers to the pressures to lower rates to levels that are
    competitive with those maintained by other utilities. Utility managers feel this pressure in
    36
    90-507
    a very real sense when their rates get out of line with those being charged by neighboring
    utilities. SDG&E Chairman Page emphatically acknowledged that his company keenly
    felt the competitive pressures of SCE prices:
    “[W]e keep working at trying to keep the rates down because we get no
    pleasure, I will tell you, out of being 70 percent [or] six cents above . . .
    Edison.” (Page FERC Tr. at 967.)
    SDG&E reacted to this competitive pressure in the early 1980s by implementing a
    program to reduce its retail rates, a program which culminated successfully in mid-1989
    with SDG&E achieving—for the first time in years—lower average retail rates than those
    charged by SCE. (Page FERC Tr. at 952–54.)
    Regulators apply pressure by utilizing the performance of other utilities as a
    benchmark to determine whether costs were prudently incurred. (Taylor, p. 33.) A clear
    example of yardstick competition is found in the comparisons of California utilities’
    performance levels used by the PUC itself. In a DRA report on management performance
    of PG&E, the staff makes it plain that PG&E’s performance was being evaluated against
    the performance of Edison and SDG&E and that the point of the comparison was to
    “maintain the utility’s interest in cutting costs and increasing efficiency.” (Taylor FERC
    Direct Testim., p. 35; Owen FERC Direct Testim., p. 183.)
    “Regulation can hold prices down to costs, but has a more difficult time
    determining reasonable cost and performance levels. A regulatory
    commission can compare costs and performance among utilities, however.
    If a neighboring utility has lower costs and better performance, then a
    utility attempting to pass through higher costs may have them disallowed
    . . . Thus, for regulated industries, the counterpart of the threat of entry by
    other private companies is yardstick comparisons, the threat of regulatory
    disallowance of costs based on comparisons to other utilities.” (Taylor
    FERC Direct Testim., p. 45.)
    Edison dismisses the relevance of yardstick competition to this case on two
    grounds: First, it argues that there are numerous utilities in the United States against
    which to compare SCE. Second, SCE asserts that the merger will save more in rates than
    yardstick competition. (Pace FERC Direct Testim. at 101–102.)
    We find neither argument persuasive. There will, it is true, be other systems after
    the merger, but there can be no doubt that for SCE, SDG&E is the most pertinent, and
    most compelling, example because it is easily the most comparable system. (Taylor
    FERC Direct Testim. at pp. 46–47.) After the proposed merger there would be only one
    37
    90-507
    other California-based private utility, PG&E. Its loads are quite different, and its resource
    base, with a large share of cheap hydroelectric generation, makes its system
    fundamentally incomparable to SCE’s. The municipal systems have markedly different
    cost structures, making them a remote comparison in ratemaking. And because the PUC
    regulates neither the municipal systems nor out-of-state private utilities, the commission
    is far less likely to be able to draw appropriate inferences from their proposals—or to
    respond authoritatively to efforts by SCE to distinguish discomfiting examples.
    The second argument, that the merger will save ratepayers more than yardstick
    competition between SCE and SDG&E, is simply a conclusory claim. SCE claims rate
    savings from the merger of between one and two percent over ten years. Even were we to
    accept that claim, Edison’s witnesses tender no evidence on the magnitude of savings
    from vigorous yardstick competition between the two systems and no basis for
    concluding that those savings would be smaller than those claimed by the merger. And,
    as noted above, claimed savings are no justification, under Public Utilities Code
    section 854, for approving a merger that eliminates competition.
    Yardstick competition, the spur to competitive pricing that forced SDG&E to
    embark on a decade long and ultimately successful battle to bring its rates below those of
    SCE, would be substantially reduced by the loss of SDG&E as a retail seller of
    electricity. The record makes it clear that the merger would adversely affect yardstick
    competition.
    2.     Franchise Competition
    Municipalities facing high utility rates can seek to take over gas and electric
    distribution within their boundaries. (Owen FERC Direct Testim., p. 180.) Municipalities
    may also seek to switch from one utility to another. (Ibid.) In a May 1986 report, SDG&E
    observed that:
    “[S]ome municipalities claim they could take over the gas and/or electricity
    as a wholesale customer from another utility with more competitive rates.
    Two cities in our service territory have already discussed the subject,
    though no serious effort has been made yet.” (Ibid.)
    Despite such fragmentary evidence and some academic commentary on the
    potential for franchise competition (e.g., Meeks, Concentration in the Electric Power
    Industry: The Impact of Antitrust 
    Policy, supra
    , 72 Colum.L.R. 64), there is insufficient
    evidence of such actual or potential franchise competition between SCE and SDG&E to
    make it a relevant consideration in this case.
    38
    90-507
    3.     Fringe Competition
    “Fringe competition is competition to serve at retail a customer or customers
    located where they could have alternative suppliers. In fringe area competition, the focus
    is on who will be successful in serving a customer or a group of customers either already
    located in or which plan to locate in a particular area, typically in border areas between
    utilities.” (Taylor FERC Direct Testim., p. 32.)
    Such competition has occurred between SCE and SDG&E in the past. In 1988
    SDG&E and Edison competed for the right to serve the community of South Laguna
    Beach, which is in SDG&E’s service territory. Evidence of the intensity and bitterness of
    that competition is reflected in a letter from SDG&E Chairman Tom Page to Edison
    Chairman Howard Allen, objecting to Edison’s “aggression” in the form of “attacks on
    SDG&E and attempts to expand into our service territory in Orange County.” (Taylor
    FERC Direct Testim., pp. 33–34.)
    SCE also competed with SDG&E for the right to serve two new subdivisions on
    the boundary between SDG&E and Edison. The landowner for the Coto de Caza
    development filed a petition for a boundary change (D.88–09–022), which petition was
    dismissed on procedural grounds. Likewise, the property owners for Rancho Santa
    Margarita have sought a boundary change as well. That petition has been stayed pending
    a decision on the merger. (Bryson, p. 30.)
    Edison asserts that any past franchise competition cannot be repeated because of a
    recently adopted PUC policy. (Pace FERC Direct Testim., p. 81.) We are reluctant to
    dismiss in perpetuity the potential for competition on the basis of current PUC policy not
    reflected in any statute. However, in light of present policy, we cannot conclude that the
    merger would adversely affect any realistic prospects for fringe competition in the
    foreseeable future.
    We therefore conclude that the proposed merger would adversely affect yardstick
    competition in retail sales but that there is no evidence of fringe or franchise competition
    that would be adversely affected.
    C.     DEALINGS WITH UNREGULATED AFFILIATES
    SCE and SDG&E are both vertically integrated already; both SCE and SDG&E
    currently produce, as well as distribute and sell, electricity. The merger would not create
    vertical integration where none existed before. However, the record reveals that vertical
    integration has had significantly different effects on the ratepayers of the two systems and
    on the competitors of the two utilities’ unregulated affiliates.
    39
    90-507
    The heart of the issue is the claim that SCE has been guilty of favoritism in its
    dealings with its own affiliates to the disadvantage of ratepayers and competing firms.
    There is substantial evidence of such favoritism. Because there is no similar allegation of
    unfair self-dealing by SDG&E with its affiliates, the assertion is that this merger will
    extend the harmful effects of SCE’s self-dealing to new customers and firms previously
    unaffected by such practices.
    SCE’s parent corporation, SCEcorp, also owns the Mission Group, which in turn
    owns four Mission companies dealing with energy and real estate development in various
    ways. Among the second tier subsidiaries is Mission Energy, one of the nation’s largest
    independent energy producers. (Weisenmiller FERC Direct Testim., p. 4.) Mission
    Energy participates in a large number of qualifying facilities (QFs) and small power-
    producing projects. One of the nation’s largest independent power producers, Mission
    jointly owns36 seventeen operational projects with a combined capacity of 1930 MW. Of
    this total capacity, Mission Energy sold 1468 MW to Edison. In 1989, Mission Energy
    sold 76% of its output to Edison, selling to Edison even when the Mission Energy
    projects were in PG&E’s territory. Sales from projects in whose ownership Mission
    Energy shares make up 54% of the projected 1990 SCE purchases from QFs, and 90% of
    the projected 1990 SCE cogeneration purchases. (Weisenmiller FERC Direct Testim., p.
    8; see also Exh. 10,300, pp. I-4 to I-7 and II-4 to II-5.)
    DRA claims, and an administrative law judge has found, considerable evidence of
    abusive practices in self-dealing between SCE and Mission. (Application of Southern
    California Edison Company (1990) Application No. 88-02-016 (Proposed Decision).)
    One consequence of this self-dealing has been for SCE to purchase so much power from
    its own unregulated affiliate that it had an oversupply of capacity and no longer was in
    the market for additional QF generation. Therefore, beyond the adverse effects on
    ratepayers, the self-dealing adversely affected competitors and competition.
    The record indicates SCE contracted for capacity and power from Mission Energy
    projects when SCE already had excess capacity. SCE concedes that “during the past
    several years, a significant quantity of non-dispatchable baseload QF capacity has been
    developed on the Edison system causing Edison to have excess generation capacity
    available.” (Budhraja FERC Direct Testim., p. 7.)37 SCE entered into contracts for the
    36
    PURPA forbids a utility or utility affiliate from owning more than 50% of a QF. (See 16 U.S.C.
    § 796, subd. (17)(C)(ii); 18 C.F.R. § 292.206.)
    37
    See also SCE Executive Vice-President Michael Peevey’s statement in the December 10, 1987,
    issue of Public Utilities Fortnightly that “[w]e have managed to become so awash with excess qualifying
    facility capacity that, if electricity were water, the Pacific Ocean would now be lapping at the Sierra
    Nevada Mountains.” As noted above, approximately 54% of SCE’s projected 1990 QF purchases from
    QFs come from QFs in which Mission Energy is a partner.
    40
    90-507
    purchase of QF capacity from Mission Energy QFs at a time (the early to mid-1980s)
    when SCE was already projecting excess capacity on its system for the late 1980s. (Clay
    FERC Answering Testim., pp. 150-55.) That such capacity developed is evident from
    SEC’s 1987 resource schedule, which showed SCE having a reserve margin of 35.2% for
    1988, including a newly created category called “standby reserve.” (Id., p. 150.) In 1988,
    SCE was required to have a reserve of only 16% (id., p. 151), indicating that it had
    significant surplus capacity.38 Further, SCE denied capacity credit to Vernon for Vernon’s
    interest in SONGS in 1981, and denied capacity credit for other resources to Anaheim
    and Azusa for interests they were considering purchasing in the Arizona Public Service
    project Cholla Generating Station. In each case, the reason given by SCE for denial of
    capacity credits was excess capacity on the SCE system.39
    SCE claims that its overcapacity was entirely the result of regulatory policies
    requiring it to contract with QFs on excessively favorable terms. (Bryson FERC Rebuttal
    Testim., pp. 5-8.)40 However, the record shows that SCE failed to take opportunities to
    obtain a change in regulatory policy until it had fully taken advantage of the opportunities
    to purchase major blocks of power from its own unregulated affiliates.
    In 1984 PG&E reported to the PUC that, due to the large number of QF contracts
    it was signing, the utility was in danger of acquiring a substantial amount of excess
    capacity. In response the PUC issued a decision on October 17, 1984 (D-84-10-098),
    suspending all terms and conditions of Payment Option 3 of PG&E’s Standard Offer 4
    contract for QF projects larger than 50 MW. This decision was reviewed by the PUC en
    banc on November 4, 1984, with SCE participating in the proceeding. SCE did not
    recommend any limitation on QF contracts in its own service area (but had expressed
    some concerns about excess capacity to PUC staff a few months before). On December 5,
    1984, the PUC affirmed the suspension as to PG&E, but took no action as to SCE. Then,
    less than two months later, on January 31, 1985, SCE moved the Commission for an
    “emergency ex parte order” to limit SCE’s obligation to purchase QF capacity. The
    38
    In fact, when one subtracts SCE’s QF capacity from its reserve margins, the result is a margin
    of around 15%, typical for electric utilities. (See Response of SCE to USDOJ Data Request DOJ–E3.)
    39
    While we focus on independent QFs as the competitors of Mission injured by the self-dealing,
    these denials of capacity credit demonstrate that other utilities are also competitors of Mission and are
    also injured by those practices. Joskow has noted that since purchases of economy energy are passed
    through to ratepayers without contributing to the utility’s profit, the utility has no incentive to meet its
    load through power purchases. (See Joskow, Regulatory Failure, Regulatory Reform, and Structural
    Change in the Electric Power Industry, in M. Baily & C. Winston, MICROECONOMICS 1989 Brookings
    Inst., quoted in Owen FERC Direct Testim. at 31.)
    40
    But see 18 C.F.R. § 292.303 (FERC regulation providing that utilities are not obligated to
    purchase QF power not needed by their systems).
    41
    90-507
    requested order was issued on February 21, 1985, three weeks after SCE asked for it.
    (Clay FERC Direct Testim., p.158.)
    Between the time that SCE refrained from advising the PUC that it might have
    excess QF capacity and the time, less than three months later, that it moved for an
    emergency order to limit its QF purchases, SCE purchased 640 MW of capacity from
    Mission’s Sycamore and ARCO-Watson projects.41 Only after those contracts were
    signed did SCE suddenly have a QF “emergency” requiring immediate PUC relief.
    In addition to vigorously disputing the charges of unfair self-dealing, SCE argues
    that any such practices have no relevance to the merger. They point out that the new PUC
    policy requires competitive bidding by QFs on utility resource additions and bans non­
    standard contracts of the type which Edison has almost universally signed with Mission
    and which are alleged to have been highly favorable to Mission. (Jurewitz FERC Rebuttal
    Testim., pp. 125-26, 179-80.) Furthermore, SCE argues that any advantage it unfairly
    gains from such practices will have to be disgorged under PUC oversight of Edison
    power contracts. A recent ALJ decision in the Kern River Cogeneration Company
    proceeding found merit in claims of SCE unfair self-dealing and recommended
    disallowing $48 million in SCE payments to Mission. (Application of Southern
    California Edison 
    Company, supra
    , Application No. 88-02-016 (Proposed Decision).)42
    While the tightened regulatory policy reduces the potential for such abuses, it does
    not eliminate that potential.43 Although competitors presumably will be given the
    opportunity to bid against Mission for resource additions, SCE will continue to control
    the terms and conditions of that bidding—establishing the kinds of QFs eligible to bid,
    setting the scoring basis for comparing bids, determining the conditions for
    interconnection or integration of the facility, and specifying the operating characteristics
    of the project. (See, e.g., Owen FERC Direct Testim. at 88-90; Exh. 10,300, IV-43.)
    There is a substantial body of evidence tending to show that SCE has a long history of
    “negotiating” with Mission terms excessively favorable to the unregulated affiliate.
    Examples of such terms are:
    41
    “By the time Edison executed the KRCC contract, it already had over 3300 MW of QF capacity
    under contract, far exceeding its goal of 2241 MW by the end of 1984.” (Exh. 10,300, App. A, p. 65.)
    42
    The fact that this proceeding took two years to get to an ALJ decision illustrates the limits of
    regulation in detecting and correcting abusive self-dealing practices.
    43
    We assume for present purposes that the PUC policies to reduce the opportunity for unfair self-
    dealing are permanent. It is, however, worth noting in passing that SCE is already pressing the PUC for
    changes in the SO4 bidding process to permit multi-attribute evaluations of bids, which would give SCE
    increased opportunity to favor its unregulated affiliates. (See Owen Direct Testim., App. BMO-Z.)
    42
    90-507
    ■		   A provision allowing the QF to terminate the contract upon 90 days’ notice
    if it becomes unprofitable to the QF (compared to the corresponding
    standard contract provision for termination only on five years’ notice. (Exh.
    10,300, pp. IV–16 to IV–18 and Appendix A; Clay FERC Direct Testim. at
    161–63.)
    ■		   Provisions requiring Edison to baseload the QF affiliate’s energy,
    guaranteeing sales that would not be made under Standard Offer 4 and
    displacing potential competing sales. (Clay FERC Answering Testim.,
    p. 161.)
    ■		   A nonstandard contract provision allowing the affiliated QF the unilateral
    right to increase its minimum contract capacity and to increase or decrease
    its additional contract capacity, allowing the unregulated affiliate to set the
    volume of sales and the price at which sales will be made. (Exh. 10,300,
    App. A, p. 48.)
    These favorable terms to the Edison unregulated affiliate can be explained in part by the
    fact that the same people responsible for representing SCE ratepayer interests in the
    negotiation of QF contracts were also high officials of the QFs themselves. For example,
    the officials of SCE responsible for the utility’s contract with the Kern River
    Cogeneration Project were also president and vice-president of an SCEcorp wholly-
    owned QF subsidiary. (Exh. 10,300, App. A, pp. 22, 85; Owen FERC Direct Testim. at
    81–82.)
    The intimate relationship between SCE and Mission also creates the opportunity
    for Mission to displace its costs onto the regulated utility—thereby obtaining a subsidy of
    the unregulated business from utility ratepayers and giving the unregulated business a
    cost advantage over competitors. One example of this phenomenon is the displacement of
    Mission personnel, recruiting, and training costs onto SCE. Several officers of Mission
    are also on the payroll of SCE, such as the president and CEO of the Mission Group, who
    is also executive vice-president of SCEcorp and executive vice-president of SCE. (Clay
    FERC Answering Testim., p. 142.) Corporate executives have traveled from SCE to
    Mission Energy in numbers that have disquieted DRA and allowed Mission Energy to
    reap the benefits of corporate recruitment and training conducted by SCE. (See
    Exh. 10,300, pp. II–15 to II–18.)
    Even if SCE is right that the PUC can disallow the fruits of self-dealing, SCE
    ignores the inherent limits on the effectiveness of such regulation. There are examples of
    effective regulation, but we agree with DRA itself that neither it nor the commission can
    reasonably be expected fully to compensate for the absence of arm’s-length negotiations
    43
    90-507
    between independent parties. (Exh. 10,300, pp. I–8 through I–10; Owen FERC Direct
    Testim. at 74–75.)
    The USDOJ has described these problems in the following terms, which we find
    pertinent to the proposed merger:
    “Nonhorizontal mergers may be used by monopoly public utilities subject
    to rate regulation as a tool for circumventing that regulation. The clearest
    example is the acquisition by a regulated utility of a supplier of its fixed or
    variable inputs. After the merger, the utility would be selling to itself and
    might be able arbitrarily to inflate the prices of internal transactions.
    Regulators may have great difficulty in policing these practices, particularly
    if there is no independent market for the product . . . purchased from the
    affiliate.[*] As a result, inflated prices could be passed along to consumers
    as `legitimate’ costs. In extreme cases, the regulated firm may effectively
    preempt the adjacent market, perhaps for the purpose of suppressing
    observable market transactions, and may distort resource allocation in that
    adjacent market as well as in the regulated market.”
    ________________________
    “[*] . . . . The use of common facilities and managers may create an insoluble cost
    allocation problem and provide the opportunity to charge utility customers for nonutility
    costs, consequently distorting resource allocation in the adjacent as well as the regulated
    market.” (USDOJ Merger Guidelines, § 4.23.)
    We conclude that the proposed merger would adversely affect competition by
    giving SCE’s unregulated affiliates unfair advantages over their competitors in meeting
    the generating demands of the SDG&E load.
    E.     SUMMARY
    We have found that the proposed merger of SCE and SDG&E would adversely
    affect competition in several markets.
    In the competition among electric utilities, the merger would have serious adverse
    effects on transmission markets that connect California to the Southwest and, to a lesser
    extent, to the Northwest. These effects are especially significant because of vertical
    effects of the merger, smothering SDG&E’s emerging role as a broker of wholesale
    power that represented an important counterforce to Edison’s historic exploitation of its
    power in the transmission markets.
    The proposed merger also adversely affects competition by increasing
    concentration in several bulk power markets. It would eliminate significant competition
    44
    90-507
    between SCE and SDG&E for the purchase of both long-term firm and short-term firm
    and non-firm bulk power in the Southwest. Although the evidence is less strong, there are
    grounds for concern that the merger would also injure future competition by eliminating
    SDG&E as a competing seller in the Southwest and Northwest short-term bulk power
    markets.
    Although the competition in retail electric service is more limited than at the
    wholesale level, such competition does exist. We conclude that the proposed merger
    would eliminate at least one recognized form of such competition, yardstick competition
    between SCE and SDG&E.
    Finally, we have concluded that the proposed merger would injure competition
    among QFs by giving unregulated affiliates of SCE increased opportunity to take
    advantage of their relationship to SCE to foreclose competitors.
    VIII. MITIGATION MEASURES
    Having found that the proposed merger will adversely affect competition, Public
    Utilities Code section 854, subdivision (b)(2), requires us to determine “what mitigation
    measures could be adopted to avoid this result.” We therefore examine each of the
    markets in which we find adverse effects on competition and consider possible mitigation
    measures.
    Theoretically, there exists an unlimited list of potential mitigation measures, which
    we make no effort to exhaust. Rather, we discuss here those remedies traditionally
    applied to antitrust injuries and those that have been suggested by the parties.
    A.     TRANSMISSION
    We have found that the proposed merger will impermissibly increase the
    concentration in transmission markets between California and both the Southwest and, to
    a lesser extent, between California and the Northwest. In so doing, the proposed merger
    would not only increase SCE’s power in the transmission markets but would also
    increase its power in bulk power markets in the Southwest and the Northwest. We have
    found that SCE has a history of abusing its control over transmission to disadvantage
    competitors in bulk power markets and that this merger would eliminate SDG&E, which
    has emerged as a broker in those markets.
    The typical remedy for a merger that violates the antitrust laws is divestiture.
    (California v. American Stores Co. (1990) __ U.S. __ (Slip Opn. at 7); United States v. E.
    I. du Pont de Nemours & 
    Co., supra
    , 
    366 U.S. 316
    , 329–31 (“Divestiture has been called
    45
    90-507
    the most important of antitrust remedies. . . . It should always be in the forefront of a
    court’s mind when a violation of § 7 has been found.”); FTC v. Western Meat Co. (1926)
    
    272 U.S. 554
    , 559.) Divestiture of the wrongfully acquired company is, of course, not an
    issue here, since SDG&E has not yet been acquired; such divestiture would be equivalent
    to disapproving the proposed merger and is therefore not a mitigation measure. However,
    one could fashion a divestiture order that permits SCE to acquire parts of SDG&E in
    exchange for divesting other assets.
    Specifically, SCE could be required, as a condition of the merger, to divest itself
    of SDG&E’s high-voltage and extra-high-voltage transmission system. Those assets
    would be sold to an unaffiliated buyer, either a new entity or one or more existing
    utilities. That would eliminate the merged company’s opportunities to take advantage of
    market power over the SDG&E transmission lines to acquire advantages in the bulk
    power market. This would fully mitigate the vertical anticompetitive effects of the
    merger, and if the sale were to a new entrant or to parties having relatively small market
    shares, it would resolve the horizontal concerns raised by the additional concentration in
    the transmission markets the proposed merger would otherwise cause.
    SCE has not raised any such possibility, but instead has proposed a series of
    conditions under which it says it will make its transmission system available to other
    utilities and which it states will avert any anticompetitive effects of the merger. (See
    Fogarty FERC Direct Testim. at 20–28; FERC Exh. 151.) Edison has previously stated its
    willingness to wheel power for competing systems whenever the transmission capacity is
    not needed by SCE for its own load. (Fogarty FERC Direct Testim. at 12.) To this
    commitment, SCE now adds the offer to construct transmission facilities upon request of
    a neighboring system or QF, at the expense of the requestor. (Id., at p. 22.) This, SCE
    asserts, will provide any other utility with access to transmission and to bulk power
    markets dependent on that transmission.
    Initially, we note that this offer, even if it has the effects SCE claims, will only
    address the vertical adverse effects of the merger. It would not alter the market shares of
    the various parties in the foreseeable future. The merger would still substantially increase
    SCE’s market share and eliminate SDG&E as a competitor for transmission services.
    This is not merely an academic observation. Absent SDG&E, a party wishing to avail
    itself of SCE’s offer will be required to negotiate the price and other conditions of
    transmission service and of any system additions. Absent a competing system, SCE will
    possess nearly unchecked power to set the price and terms.
    But more fundamentally, we believe that the long history of anticompetitive SCE
    practices in the wholesale power markets renders any such “commitments” wholly
    insufficient to provide other utilities meaningful access to the SCE transmission system.
    46
    90-507
    Nearly two decades of such commitments has proven inadequate to assure competing
    utilities equal access to SCE’s transmission system. The inadequacy lies in the nature of
    such promises themselves and the manner in which SCE has implemented them.
    SCE has reserved to itself the right to specify the conditions under which it will
    interconnect with another system. SCE has a legitimate need to specify such conditions to
    protect the integrity of its system. However, the record reflects repeated abuses of that
    right, with SCE claims that range from the dubious to the plainly spurious, in an effort to
    defeat competing utilities’ bulk power transactions.
    These are not problems that can be dealt with through further, or more elaborate,
    conditions, particularly when the requested service is short-term transmission. Even in
    long-term wheeling arrangements, where presumably one could tighten the terms of the
    commitments and specify a mechanism to arbitrate or adjudicate conflicting claims about
    SCE practices, it is doubtful that such a cumbersome arrangement could effectively
    resolve the myriad technical issues. But bulk power markets are dynamic, with
    opportunities for purchases and sales arising without advance notice and expiring in
    minutes or hours. There is simply no time for a mechanism for a neutral party to hear and
    resolve SCE claims of technical reasons why a given request cannot be accommodated, to
    hear and resolve disputes over pricing, to hear and resolve SCE claims of capacity
    shortages and line-loadings that SCE can itself create through creative scheduling on its
    own system. Indeed, the evidence indicates Edison’s keen awareness of the ephemeral
    nature of these opportunities and suggests Edison has sought to make it cumbersome for
    other utilities to deal with utilities dependent on SCE for transmission.
    We also note that Edison’s commitments themselves contain limitations that
    reserve to Edison continued market power in transmission to obtain advantage in bulk
    power markets. In particular, SCE has asserted that it would not make transmission
    available whenever it has a use for the capacity itself. Thus, for example, if SCE finds
    itself in competition for a supply of bulk power that comes available in the Southwest and
    the competing system needs SCE transmission to wheel the power, SCE can eliminate the
    competitor by asserting its own need for the transmission capacity to deliver the same
    power to its own system.
    We conclude that neither the commitments made by SCE nor any adjustment to
    those commitments can mitigate the adverse effects of this merger on transmission
    markets.
    47
    90-507
    B.     BULK POWER
    Because we have concluded there is no way to avoid the proposed merger’s
    adverse effects on competition in transmission, we are compelled to conclude as well that
    the adverse effects on the bulk power markets dependent on transmission also cannot be
    avoided. As long as Edison maintains effective control of competitors’ access to
    interregional markets, the injury to the bulk power markets cannot be effectively
    mitigated.
    Separate from the anticompetitive effects from the transmission market on bulk
    power markets, we have also found the merger, when viewed simply as a horizontal
    merger, adversely affects bulk power markets by increasing concentration and
    eliminating competition between SCE and SDG&E for the purchase of both long-term
    firm and short-term firm and non-firm bulk power in the Southwest, and, to a lesser
    extent, by eliminating SDG&E as a competing seller in the Southwest and Northwest
    short-term bulk power markets. We can identify no mitigation measures that could avoid
    this result, and none have been proposed. The ineluctible fact is that this merger
    eliminates competition that cannot be replaced.
    We therefore find that the adverse effects of the merger on competition in the bulk
    power markets cannot be prevented by any mitigation measures.
    C.     RETAIL SERVICE
    We know of no mitigation measures that would avoid the loss of yardstick
    competition from this proposed merger. We conclude that this merger would eliminate
    the single competing system most appropriate for comparison to SCE in retail
    ratemaking.
    Unquestionably, measures could be taken to strengthen the PUC’s own ratemaking
    apparatus. We note that the proposed combined company would have an array of
    employees dedicated to regulatory affairs that would substantially outnumber the number
    of PUC employees devoted to examining SCE rate filings and making counterproposals
    on behalf of ratepayers. Adjustments in that balance of power, and doubtless other steps
    to fortify the PUC regulatory process, could improve regulatory performance. But the
    point of yardstick competition is that it gives regulators a clearly comparable, familiar
    system against which to judge the utility, and that simply cannot be replaced were this
    proposed merger to be approved.
    And more fundamentally, this is not an instance in which regulation functions as a
    substitute for competition. The general principle guiding the relationship between
    48
    90-507
    regulation and competition is that the two are intended to coexist and be reconciled
    absent a clear legislative intent to displace one for the other. (E.g., National Gerimedical
    Hospital and Gerontology Center v. Blue Cross of Kansas City (1981) 
    452 U.S. 378
    , 392­
    93; Silver v. New York Stock Exchange (1963) 
    373 U.S. 341
    , 357.) In this case, to the
    contrary, the Legislature has indicated, in Public Utilities Code section 854, a clear intent
    that competition and regulation supplement one another and that the commission ensure
    the continued effectiveness of competition notwithstanding the fact that Edison’s
    wholesale and retail businesses remain regulated. We therefore conclude that under
    section 854, subdivision (b)(2), regulation, viewed as a substitute for competition, does
    not constitute a mitigation measure to avoid a merger’s adverse effects on competition.44
    Thus, we conclude that there are no mitigation measures available that can avoid
    the adverse effects of the proposed merger on retail competition.
    D.      DEALINGS WITH UNREGULATED AFFILIATES
    The competitive injury we have found in SCE’s dealings with its unregulated
    affiliates lies in the opportunities the relationship with those affiliates gives SCE for self-
    dealing that disadvantages competitors’ QFs and other prospective power suppliers. That
    is an effect that can, indeed, be entirely avoided.
    DRA has proposed that SCE be required to divest its unregulated affiliates doing
    business with SCE. We agree that would avoid the anticompetitive effects arising from
    Edison’s relationship to those affiliates. SCE would no longer have the economic
    incentive to favor the former affiliates, and competing power suppliers would be on an
    even footing in bidding for contracts with SCE.
    We do not believe a condition short of divestiture could successfully be crafted to
    deal specifically with the SDG&E load, which the proposed merger would subject to the
    self-dealing. In theory, one might merely proscribe SCE affiliates from contracting to
    meet the SDG&E load. In fact, once the two systems are integrated, there is no way
    effectively to identify which portion of the load, or load growth, is attributable to the
    former SDG&E system, and we believe any such condition would not be effective.
    44
    Regulation can constitute a mitigation measure where the regulation is expected to prevent an
    injury to competition. For example, where regulation could preserve a competitor who would otherwise
    be eliminated from a market, that certainly would be an effective mitigation measure under the statute.
    But regulation cannot satisfy the statute by purporting to substitute for competition, for example by
    purporting to set prices at their theoretical competitive level.

    IX.    CONCLUSION
    The electric utility industry is already highly concentrated. It has a long history of
    serious impediments to effective competition, in part from a course of conduct followed
    by SCE over many years that has exploited its market power to the disadvantage of
    competitors. The proposed merger would inflict further injury on competition. We find
    that the merger does not meet the requirements of Public Utilities Code section 854,
    subdivision (b)(2), either as proposed or as it might be conditioned by the PUC.
