    ____________________________________________________
    Petition for Review of Orders of the
    Federal Energy Regulatory Commission
    _____________________________________________________
    (August 25, 1993)
    Before REYNALDO G. GARZA, SMITH, and BARKSDALE, Circuit Judges.
    BARKSDALE, Circuit Judge:
    Gulf States Utilities Company (GSU) challenges the Federal
    Energy Regulatory Commission's denial of both its request to
    correct, retroactively and prospectively, claimed billing errors,
    and its application for a waiver of related filing requirements,
    arising from its contract with Cajun Electric Power Cooperative,
    involving GSU's high-voltage electricity transmission system, owned
    in part by Cajun.    We REVERSE and REMAND.
    I.
    GSU is a utility company servicing customers in Louisiana and
    Texas; and, under a Power Interconnection Agreement executed in
    1978, it provides electricity transmission services to Cajun, a
    government-funded rural electric cooperative in Louisiana. Because
    Cajun's     cost    of   capital    is     less   than    GSU's,   due   to     Cajun's
    government-funded status, GSU and Cajun executed Service Schedule
    CTOC in 1980 (the CTOC agreement), which provided that the two
    companies would establish a co-owned Integrated Transmission System
    (ITS) comprised of qualified high-voltage transmission facilities
    (QTFs).1     In exchange for its investment in the ITS, Cajun would
    not be billed for its use of the ITS to the extent of that
    investment.        In essence, the plan allowed Cajun to invest in the
    ITS in lieu of paying a portion of the bill that would otherwise be
    payable to GSU.
    The    CTOC    agreement     established      a     rather   complex      billing
    mechanism with regard to the ITS.             In order to credit Cajun for its
    investment, GSU was to deduct GSU's revenue requirements associated
    with the ITS from Cajun's monthly general transmission charges, in
    the   form    of    "CTOC   credits".         The   CTOC     credits     were    to   be
    "determined on the basis of the methodology, procedures and data
    used as      the    basis   for    GSU's    transmission      service     rates    most
    recently approved or accepted for filing by FERC ...".
    Additionally, in the event that Cajun's investment in the ITS
    was not proportionate to its relative use, an equalization charge
    would be imposed.        The equalization charge was to be calculated by
    multiplying the amount of Cajun's investment deficiency by a
    percentage referred to as "Factor APM".                  Factor APM is computed by
    dividing GSU's annual revenue requirement associated with the ITS
    1
    If GSU provides service to Cajun over its entire system, part
    is provided over the ITS (owned in part by Cajun), and the rest is
    provided over GSU's low-voltage facilities.
    - 2 -
    by its total investment in the ITS.                   For example, if GSU invested
    a total of $100 million in the ITS, and its annual revenue
    requirements for the ITS were $20 million, Factor APM would be 20%
    for that year.       Accordingly, Cajun's yearly equalization charge
    would be 20% of the amount of its investment deficiency.                      Because
    the monthly equalization charges were to be based on estimates, the
    CTOC agreement also provided for annual "true-ups" once the actual
    figures became available.
    In early 1981, GSU submitted the CTOC agreement for FERC
    approval.       In    response          to     FERC's    request     for   additional
    information, GSU specified, inter alia, the Factor APM to be used
    initially. FERC accepted the agreement for filing that August, but
    advised GSU that "any changes in the applicable Equalizing Charge
    resulting    from    the     use   of    a     Factor   APM   different    from   that
    specified in your instant filing, must be timely filed ... as a
    change in rate schedule in accordance with [regulations]".                        FERC
    did not similarly direct GSU to file changes to the CTOC credits,
    and the CTOC agreement did not specify how such changes were to be
    initiated or implemented.            Accordingly, until GSU's filing in the
    present proceeding, CTOC credits (as a component of the stated
    rate) were never filed with FERC.
    The CTOC agreement billing provisions took effect January 1,
    1982, when Cajun acquired two high-voltage transmission lines --
    QTFs -- from GSU.      At that time, GSU computed Cajun's CTOC credits
    from   the   data    filed    with      FERC     in   GSU's   most   recent   general
    - 3 -
    transmission rate filing, submitted in 1980. It used the specified
    Factor APM (24.4047%), which was also based on that data.
    In July 1982, GSU submitted new general transmission rates for
    filing. FERC approved a settlement in that case in June 1983, with
    the new rates made effective July 1982.            See Gulf States Utils.
    Co., 25 F.E.R.C. ¶ 61,131 (1983).
    GSU again submitted new general transmission rates in July
    1985.   In January 1987, FERC approved a settlement of that case,
    which provided for two new rates -- one effective July 1985, and a
    superseding rate effective July 1986.       See Gulf States Utils. Co.,
    38 F.E.R.C. ¶ 61,048 (1987). Cajun intervened in the second (1985)
    rate case to protest GSU's designation of the QTFs under the CTOC
    agreement   (QTF   dispute),2   but   the   1987    settlement   agreement
    expressly excluded any resolution of that dispute.3
    As noted, in neither its 1982 nor its 1985 filing did GSU
    separately designate revised CTOC credits or Factors APM. However,
    upon each filing, it recalculated both, based on the new data
    submitted, and billed Cajun accordingly.             FERC accepted GSU's
    refund compliance filings for each case in May 1984 and September
    1987, respectively.
    2
    In sum, Cajun contended the GSU was not including QTFs owned
    by Cajun, resulting in improper (excessive) equalization charges to
    Cajun, and denying it proper access to the ITS.
    3
    Because of the QTF dispute, Cajun had stopped paying the true-
    ups, and GSU had stopped billing Cajun under the CTOC rate
    procedures. The settlement agreement provided: "This agreement is
    not intended to resolve an existing billing dispute between Cajun
    and [GSU] under the CTOC service schedule .... [T]his Agreement is
    made without prejudice to Cajun's and [GSU's] rights regarding such
    dispute and its ultimate resolution".
    - 4 -
    In July 1987, Cajun renewed its claims with FERC regarding the
    QTF dispute, among others.      GSU answered, and filed its own action
    with FERC, proposing to cancel the CTOC agreement.            FERC denied
    GSU's request to cancel, see Cajun Elec. Power Corp., Inc. v. Gulf
    States Utils. Co., 41 F.E.R.C. ¶ 61,136 (1987), and affirmed the
    denial on rehearing, see Gulf States Utils. Co., 42 F.E.R.C. ¶
    61,163 (1988).
    Meanwhile, GSU allegedly discovered that it had erred all
    along in calculating the CTOC credits. In November 1987, after the
    denial of its request to cancel the CTOC agreement, GSU began
    billing Cajun using revised (lowered) CTOC credits, resulting in an
    annual increase in the billings to Cajun of approximately $4
    million. Cajun has paid those increased charges. Additionally, as
    noted, GSU had never filed, as directed, the changes to Factor APM
    from the figure initially filed in 1981.       Accordingly, on June 20,
    1988,   GSU   submitted   for   filing    retroactive   and   prospective
    revisions to the CTOC credits and Factors APM, requesting a waiver
    of the Factor APM filing requirement for good cause.
    In August 1988 (Initial Order), FERC rejected GSU's proposed
    retroactive changes to the CTOC credits, holding that those credits
    had been at issue in, and resolved by, the settlements of the 1982
    and 1985 rate cases in 1983 and 1987, respectively.            See Cajun
    Elec. Power Corp., Inc. v. Gulf States Utils. Co., 44 F.E.R.C. ¶
    61,259, 61,972 (1988) [hereinafter 44 F.E.R.C. at ____].               In
    addition, it denied GSU's request for a waiver of the Factor APM
    filing requirement. 
    Id. at 61,970-71.
    For prospective application
    - 5 -
    only, FERC accepted GSU's proposed Factor APM, based on the 1986
    rate, and set that matter for hearing.            
    Id. Finally, for
    purposes
    of hearing and decision, FERC consolidated GSU's proceeding with
    Cajun's involving the QTFs.     
    Id. at 61,972.
               With respect to the
    CTOC credits, both GSU and Cajun requested clarification or, in the
    alternative, rehearing.
    Pending    that   rehearing,    an     ALJ    held    a   hearing    on   the
    consolidated matters, and issued a decision in May 1989.                 See Cajun
    Elec. Power Corp., Inc. v. Gulf States Utils. Co., 47 F.E.R.C. ¶
    63,024 (1989). The ALJ interpreted FERC's Initial Order to address
    only pre-July 26, 1985, CTOC credits (the effective date of the
    settled 1985 rate case).    
    Id. at 65,057.
    Accordingly, he proceeded
    to address the post-July 26, 1985, CTOC credit dispute, and held in
    GSU's favor on the alleged errors.          
    Id. at 65,057-58.
          He stated:
    "[W]ith the understanding that [GSU's] calculations have been
    somewhat erroneous in the past, I conclude that the methodology and
    figures computed by [GSU's witness] now accurately project the CTOC
    credits ...".    
    Id. In April
    1992, nearly four years after its Initial Order, FERC
    again rejected the proposed retroactive CTOC credits and Factors
    APM, and denied the requested waiver of the Factor APM filing
    requirement (Rehearing Order).        See Cajun Elec. Power Corp., Inc.
    v. Gulf States Utils. Co., 59 F.E.R.C. ¶ 61,041, 61,137-41, 61,143
    (1992) [hereinafter 59 F.E.R.C. at ____].                 It upheld the ALJ's
    determination regarding the Factor APM, based on the 1986 rates, to
    be applied prospectively (from August 1988), 
    id. at 61,143,
    but
    - 6 -
    reversed his finding with regard to post-July 1985 CTOC credits,
    holding that that dispute was not properly before the ALJ in light
    of FERC's Initial Order, 
    id. at 61,138.
    Reiterating that the CTOC credits for July 1985 forward had
    been settled with the 1985 rate case, FERC ordered GSU to refund
    amounts relating to revised CTOC credits which had been billed
    since November 1987 using the allegedly correct method (as noted,
    approximately $4 million annually). 
    Id. at 61,141.
    Finally, "[t]o
    reduce future confusion and uncertainty", FERC directed GSU in each
    subsequent   general   transmission    rate   filing   to   delineate
    specifically the CTOC credits.    
    Id. at 61,137.
      GSU timely filed
    its petition for review of the rulings on the CTOC credits and
    Factors APM; the QTF dispute is not before us.
    II.
    GSU contends that FERC erred in (1) denying GSU a waiver of
    the Factor APM filing requirement; (2) rejecting retroactive (pre-
    August 21, 1988) changes to the CTOC credits; and (3) rejecting
    CTOC credits for prospective effect (post-August 21, 1988).4
    We will reverse a FERC order "only if [its] decision is
    arbitrary, capricious, or otherwise not in accordance with law".

    of the order's essential elements is supported by substantial

    (5th Cir. 1988).    Furthermore, "[n]o objection to the order of the
    Commission shall be considered by the court unless such objection
    shall have been urged before the Commission in the application for
    rehearing unless there is reasonable ground for failure so to do".

    824 F.2d 417
    , 433-34 (5th Cir. 1987).
    A.
    For use with the rates that became effective in 1982, 1985,
    and 1986, GSU requested approval of Factors APM different from that
    approved in 1981.    Prior to 1988, as a result of using Factors APM
    different from that approved in 1981, GSU collected approximately
    $3.8 million more than it would have using the approved factor.     It
    has been ordered to refund that amount to Cajun.     GSU contends that
    "[w]ithout any explanation, [FERC] ignored [GSU's] showing of good
    cause" for the waiver of the requirement that Factor APM changes be
    filed as rate changes.     Section 205(d) of the Federal Power Act
    (FPA), 16 U.S.C. § 824d(d) provides:
    Unless the Commission otherwise orders, no change
    shall be made by any public utility in any [rates
    subject to FERC's jurisdiction] except after sixty
    days' notice to the Commission ....             The
    Commission, for good cause shown, may allow changes
    - 8 -
    to take effect without requiring the sixty days'
    notice ....
    Because the waiver provisions are committed to FERC's discretion,
    GSU must show an abuse of that discretion.                  Hall v. FERC, 
    691 F.2d 1184
    , 1191 (5th Cir. 1982), cert. denied, Arkla, Inc. v. Hall, 
    464 U.S. 822
    (1983).
    In the Initial Order denying the waiver, FERC explained that
    (1) GSU's failure to comply with the filing requirements was not
    excused by the ongoing billing dispute with Cajun, because that
    dispute    involved     the    QTFs,     not    Factor      APM;    (2)    contractual
    provisions     that    fairly      implied      "some      waiver    of    the     notice
    requirements" by Cajun did not contemplate GSU's lengthy delay in
    filing the changes; and (3) GSU had been directed to file any
    changes to Factor APM.             See 44 F.E.R.C. at 61,970-71.                  In its
    Rehearing Order, FERC noted GSU's contentions that denial of a
    waiver    would   produce      a     windfall    to     Cajun,      contrary      to   the
    contractually established rates, and that Cajun, in the CTOC
    agreement, impliedly waived any notice requirements.                              See 59
    F.E.R.C. at 61,142. FERC summarily concluded, however, that it did
    "not   find    good    cause    to    grant     [GSU's]     request       for    waiver",
    explaining      only   that     GSU    "failed        to   abide     by    the     notice
    requirement" of which it had been expressly advised.                              
    Id. at 61,143.
    GSU disputes FERC's determination, and contends that FERC
    wholly failed to address its good cause arguments; particularly,
    that Cajun had notice of increases and, without protest, paid the
    bills containing those increases.                Additionally, GSU emphasizes
    - 9 -
    that the CTOC agreement provided for the increases and for some
    waiver    of   the    notice       requirements   (which,    as    noted,    was
    acknowledged by FERC), and that FERC already had approved the
    general transmission rates upon which the Factor APM changes were
    directly based.
    FERC is vested with discretion in deciding whether to grant
    the requested waiver; to find an abuse of that discretion requires
    most substantial justification.           We find it here.        GSU has shown
    good cause for the waiver, and FERC's summary discussion of the
    reasons for its denial does not "set out clearly the ground that
    forms the basis for the denial of discretionary relief", Columbia
    Gas Dev. Corp. v. FERC, 
    651 F.2d 1146
    , 1160 n.18 (5th Cir. 1981),
    such that we can determine whether it gave reasoned consideration
    to GSU's assertions of good cause.
    A principle purpose of the filing provisions of the FPA is "to
    give advance notice of proposed rate changes" to the customer.
    Union Texas Prods. Corp. v. FERC, 
    899 F.2d 432
    , 433 (5th Cir. 1990)
    (reversing the denial of a waiver where, inter alia, the needed
    information appeared elsewhere in the general transmission rate
    filings).      It does not appear that FERC gave consideration to
    whether that purpose was satisfied here.            Not only did Cajun have
    actual notice of increases in Factor APM, but there appears to be
    no dispute that the proposed changes are provided for by the CTOC
    agreement.     Therefore, the emphasis by FERC on GSU's delay of
    several   years      in   filing    for   a   different   factor    is   greatly
    - 10 -
    ameliorated.       In short, the filing could not have come as a
    surprise to Cajun.
    In the final analysis, FERC's principal reason for denying the
    waiver appears to be the fact that GSU failed to make the required
    filings.       But, needless to say, if this were the criteria for
    denying    a    filing     waiver,   waiver    would   never    be   granted.
    Additionally, GSU's failure to follow FERC's express instructions
    to file Factor APM changes does not justify the $3.8 million
    penalty which FERC, in effect, seeks to impose for the error.               In
    Union Texas, our court stated that "the Commission's punctilious
    insistence that the failure to follow its directions in the minor
    respect here involved should result in such a disproportionately
    heavy   penalty    [$1.8    million]   works    a   manifest   injustice   and
    constitutes an abuse of 
    discretion". 899 F.2d at 437
    .      Although,
    arguably, the error involved in Union Texas was more minor than
    GSU's, the forfeiture still is not justified.
    Accordingly, we reverse the denial of the waiver.                Because
    FERC has not passed on the correct Factor APM to be used in
    relation to the 1982 and 1985 rates, we remand for such further
    proceedings as it deems appropriate in this regard.
    B.
    GSU claims that it discovered that past bills had overstated
    the CTOC credits.        As noted, in November 1987, GSU began billing
    Cajun using revised (lower) CTOC credits, resulting in Cajun being
    charged annually approximately $4 million more; and Cajun has paid
    those increased billings to date.             In June 1988, GSU filed the
    - 11 -
    corrected credits in this proceeding.              At issue are both the pre-
    August     21,   1988,   billings     (retroactive)       and    those   billings
    subsequent to then (prospective).
    1.
    With respect to GSU's proposed retroactive changes to the CTOC
    credits, we also reverse.         The dispute appears to involve highly
    technical    questions    regarding        the   method   of    calculating   CTOC
    credits; the parties do not explain the details in their briefs.
    In   its    Rehearing    Order,     FERC    characterized       the   dispute   as
    reflecting "substantive questions with respect to the operation of
    Service Schedule CTOC", rather than simple "billing errors".                    59
    F.E.R.C. at 61,137.       With the exception of the ALJ's hearing in
    late 1988, GSU has not been heard on the merits of these questions.
    As noted, FERC's rejection of the proposed changes rests
    solely on its determination that the CTOC credits were settled with
    the respective general transmission rate cases.                  Initially, FERC
    determined that the express exclusion of the "existing billing
    dispute" in the 1987 settlement did not refer to the present
    dispute.    
    Id. at 61,138.
       It then reasoned (1) that Cajun may have
    reasonably expected the methodology for calculating CTOC credits to
    remain the same in the 1985 filing as in the 1982 filing; (2) that
    Cajun may have reasonably anticipated the approximate revenue
    impact of the settlements, including the CTOC credits; (3) that the
    magnitude of the proposed revisions would "completely undo[] the
    balancing of interests" that underlay FERC's approval of the
    settlements as fair and reasonable and in the public's interest;
    - 12 -
    and (4) that particular CTOC credits were included in the general
    transmission rate filings as components of the "CTOC Adjustment" in
    the cost of service used to determine GSU's basic rates to all of
    its transmission customers.               
    Id. at 61,140-41
    & n.74.
    GSU    contends    that       the    express      exclusion     in     the   1987
    settlement, see supra note 3, did reference the present dispute.
    It further contends that the record is devoid of evidence that the
    settlements included any mention of particular CTOC credits or that
    they   were    based     on   any    assumptions         about   the   CTOC    credits.
    Finally,      GSU   asserts     that       the   filed    rate   doctrine      mandates
    correction of the alleged errors.5
    As an initial matter, we find substantial evidence to support
    FERC's conclusion that the present dispute was not expressly
    excluded by the 1987 settlement. In making its determination, FERC
    closely examined the relevant evidence, including Cajun's protest
    to GSU's refund compliance report in the 1985 rate case, FERC's
    letter   order      rejecting       the    initial    refund     compliance     report,
    Cajun's complaint in the QTF dispute, and GSU's answer in that
    dispute.      We need not restate FERC's reasoning with respect to
    each; it thoroughly considered and discussed the evidence, and we
    find its conclusions reasonable.                 Perhaps most persuasive is the
    fact that GSU's claimed errors were assertedly not even discovered
    until after execution of the settlement in 1986, approved by FERC
    5
    FERC contends that because GSU failed to specify the filed
    rate doctrine as a basis for its position on rehearing, it is
    jurisdictionally barred from raising it here. We need not address
    this contention, because we do not rely on that doctrine as a basis
    for our holding.

    in January 1987.     (As noted, GSU did not begin billing with the
    revised CTOC credits until November 1987.)
    That the present dispute was not expressly excluded by the
    1987 settlement, however, does not resolve whether the CTOC credits
    were settled (fixed) by either the 1983 or 1987 settlements.            In
    its Rehearing Order, FERC acknowledged that "[GSU] has never been
    required by the terms of Service Schedule CTOC or by the Commission
    to explicitly file the CTOC credits", 59 F.E.R.C. at 61,136, and
    that "until the filing in this proceeding CTOC credits have never
    been explicitly filed with the Commission as a numerical component
    of the stated rate", 
    id. at 61,135.
              It would seem unlikely,
    therefore, that either settlement would include reference, either
    express or implied, to the CTOC credits in issue.
    FERC's first three reasons for holding that the CTOC credits
    were included in the settlements constitute mere speculation.
    First, FERC's conclusion that "it is not unreasonable to conclude"
    that the CTOC credits would be calculated under the 1985 rates
    using the same method that was used to calculate them under the
    1982 rates, 59 F.E.R.C. at 61,140, does not address whether Cajun
    actually made   or   relied   upon   any   such   conclusion   during   the
    settlement negotiations.      Moreover, this logic merely bootstraps
    onto an assumption that changes based on the 1982 rates should be
    rejected.   Second, FERC's determination that "it is reasonable to
    assume" that Cajun, in entering into the settlements, "anticipated
    the approximate revenue impact, after netting of the CTOC credits",
    
    id., similarly constitutes
    speculation in the absence of evidence
    - 14 -
    that any such anticipation occurred or was relied upon.         Finally,
    the bare statement that the magnitude of the proposed changes
    renders    them   inconsistent   with     FERC's   acceptance      of   the
    settlements, 
    id. at 61,141,
    is unsupported by any evidence that
    assumptions regarding the amount of the CTOC credits somehow
    underlay the settlements, and is most questionable in light of
    FERC's own explanation that CTOC credits can be determined only
    after the general transmission rates are fixed (settled).6         We find
    no evidence, and FERC points to none, that any of these assumptions
    were actually made or relied upon.
    The only concrete basis for FERC's determination that the CTOC
    credits were settled with the rate cases is its conclusion that
    they were included in the settled rates as components of the CTOC
    Adjustment, which comprises part of GSU's general transmission
    rates.    In its Initial Order, FERC noted that although GSU was not
    6
    In its Rehearing Order, FERC         explained   the   CTOC    credit
    calculation process as follows:
    [E]ach time a change in the basic transmission rate
    is accepted or approved, under Service Schedule
    CTOC an associated CTOC credit should be derived
    based upon the cost assumptions used to develop the
    basic transmission rate. If [GSU's] proposed basic
    transmission rate is contested and subsequently
    modified (for example, pursuant to a settlement
    agreement), under Service Schedule CTOC the CTOC
    credit should likewise be modified. Although ...
    CTOC credits are a stated amount on each month's
    transmission bill sent to Cajun, until the filing
    in this proceeding CTOC credits have never been
    explicitly filed with the Commission as a numerical
    component of the stated rate.
    59 F.E.R.C. at 61,135 (emphasis added). Thus, no CTOC credit can
    be determined until after the general transmission rates are fixed.
    - 15 -
    required to file the CTOC credits, the data it submitted in support
    of its proposed general transmission rates incorporated "a Cajun
    rate reflecting only low voltage facilities" (i.e., the general
    transmission rate less the CTOC credits).               44 F.E.R.C. at 61,972.
    In its Rehearing Order, FERC explained that "[p]articular CTOC
    credits were incorporated within the cost of service associated
    with the proposed [general transmission] rates", in that "the CTOC
    credits are a component of a `CTOC Adjustment' in the cost of
    service used to determine [GSU's] basic rates to all of its
    transmission customers".          59 F.E.R.C. at 61,140 & n.74 (emphasis
    added).
    GSU asserts that only the formula for determining the CTOC
    Adjustment is stated.          FERC explained that the CTOC Adjustment is
    "the     difference     between     Cajun's      CTOC    credits     and    Cajun's
    equalization payments" -- in other words, the net credit given
    Cajun for its ITS investment.              
    Id. at 61,140
    n.74.        GSU asserts
    that application of this formula in turn necessarily requires
    calculation     of    actual    CTOC   credits    (which,     as   noted,    can   be
    determined only after the general transmission rates are fixed) and
    actual equalization charges (which, as noted, are determined only
    after    each   year-end       true-up).      Thus,     GSU   argues,      the   CTOC
    Adjustment is by definition an estimate, in that both the CTOC
    credits and the equalization charges are determined through formula
    rates.
    FERC does not respond to this contention, nor does it cite any
    record support in its brief.            The Rehearing Order cited only the
    - 16 -
    testimony of GSU witness James E. Striedel, see 59 F.E.R.C. at
    61,140 n.74, which establishes only the formula described above.
    At the December 1988 hearing before the ALJ, Striedel was asked,
    "How are the CTOC credits reflected in ... the cost of service of
    GSU's ... customers?"        He explained the formula and replied, "That
    net credit or what is called the CTOC adjustment is allocated as a
    part of the cost of service to all customers ...".
    In his prepared testimony submitted to FERC, Striedel again
    was   asked:     "How   does     [GSU]   reflect    the   CTOC    credits   and
    equalization charge payments in determining the rates to its other
    customers?"      He replied: "The net credit received by Cajun is a
    transmission service cost and is included in [GSU's] cost of
    service studies and allocated to all jurisdictions which utilize
    the integrated transmission system. This net credit given to Cajun
    is called the CTOC Adjustment in [GSU's] cost of service."             He also
    explained that, in addition to removing GSU's revenue requirements
    for the ITS, the CTOC credits "should further act to remove the
    CTOC Adjustment" from Cajun's bills.                As GSU points out, the
    testimony makes no reference to what was actually filed with FERC
    or included in the settlement agreements. Furthermore, no specific
    CTOC credits nor any methodology for determining them is mentioned.
    FERC     failed   to     support   with     substantial    evidence   its
    determination that the CTOC credits in issue were included in any
    way in the respective settlements.              Accordingly, we reverse.     On
    remand, GSU must be accorded a determination on the merits of the
    "substantive questions with respect to Service Schedule CTOC"
    - 17 -
    presented by its allegations that the CTOC credits were calculated
    erroneously       prior    to     November    1987.        The     result    of     that
    determination should then be applied retroactively to January 1,
    1982, when the CTOC agreement first took effect.
    2.
    Our reasons for reversal with respect to retroactive changes
    to the CTOC credits apply with equal force to prospective (post-
    August 21, 1988) changes, but additional factors weigh heavily in
    favor of GSU on this issue.            Foremost is FERC's nearly four-year
    delay    in   resolving     this    dispute,    which      would    have     cost    GSU
    approximately $16 million.7           Although FERC's instruction to GSU to
    file CTOC credit changes with its general transmission rate filings
    will avoid future disputes, that instruction was not in place in
    1988.    Moreover, the errors GSU seeks to correct allegedly are
    independent of the "methodology, procedures and data" used as the
    basis for the rates on file, such that a new general transmission
    rate filing would be unnecessary to correct them.
    Previously, GSU had not been obligated to file CTOC credits
    either    under    the    CTOC     agreement    or    by    FERC.         Substantial
    disagreement was ongoing with respect to related aspects of the
    agreement; specifically, the QTF dispute.                  Finally, the ALJ had
    handed down a favorable ruling on the merits of the billing dispute
    in   1989.     Under      these    circumstances,     GSU    had     no     reason    to
    7
    As noted, the amount in controversy with respect to the
    alleged billing errors for CTOC credits is approximately $4 million
    annually. As also noted, since November 1987, Cajun has paid the
    revised CTOC credits.
    - 18 -
    anticipate that a new filing of its general transmission rates
    would be required in order to resolve the present dispute.     For
    these reasons, we reverse FERC's refusal to consider the changes
    prospectively.
    III.
    In sum, we hold that FERC reversibly erred in denying GSU a
    waiver of the filing requirement with respect to the pre-1988
    Factor APM changes, and in refusing to consider GSU's requested
    changes, both retroactive and prospective, to the CTOC credits.
    The correctness of the proposed CTOC credit changes under the
    contract and of the proposed Factors APM in relation to the 1982
    and 1985 filed rates are issues to be resolved on remand.
    For the foregoing reasons, FERC's orders are REVERSED, and the
    case is REMANDED for further proceedings consistent with this
    opinion.
    REVERSED and REMANDED.
