Rogers, Circuit Judge:


1
Potomac Electric Power Company  ("PEPCO") petitions for review of two orders of the Federal  Energy Regulatory Commission ("FERC") denying its request under § 206 of the Federal Power Act ("FPA"), 16  U.S.C. S 824e (1994), for unilateral modification of the rates  prescribed by a long-term, fixed rate, power transmission  service agreement between PEPCO and the Allegheny Power  System ("APS").  Because FERC did not abuse its discretion  in applying the stringent Mobile-Sierra public interest standard, and because a mere rate disparity or a benefit to the  purchasing utility or its customers from a rate modification  does not suffice, without more, to satisfy that standard, we  conclude that FERC's decision to dismiss the complaint was a  reasonable exercise of its authority.  Accordingly, we deny the petition.

I.

2
In 1987, PEPCO entered into an 18.5 year power supply  agreement with the Ohio Edison System, which was comprised of Ohio Edison Company and Pennsylvania Power  Company.  In order to effect delivery of the power to  PEPCO's service area, PEPCO and the Ohio Edison System  each entered into a transmission service agreement with the  APS, an integrated electric utility system directly connected  to both PEPCO and the Ohio Edison System.  Under the  three agreements, PEPCO would purchase contract entitlements to a share of the Ohio Edison System's installed  generating capacity and associated energy, APS would purchase from the Ohio Edison System the power intended for  PEPCO, and APS would, in turn, resell the power purchased from the Ohio Edison System to PEPCO.  The dispute in theinstant case involves the agreement between PEPCO and  APS.


3
PEPCO's agreement with APS provided in relevant part  that the base rate for the APS transmission service would  commence at $1.70 per kW-month, increase to $2.255 per Kw-month in 1994, and increase again to $2.815 per kW-month in  1999.  In addition, the agreement required PEPCO to pay an  "adder" of $1.00 per megawatt-hour for each megawatt-hour  of energy that APS delivered.  Furthermore, the agreement  was a "fixed rate" contract, meaning that the parties agreed  not to unilaterally request a rate change from the Commission, as provided in section 9.3 of the agreement, which  stated:


4
It is the intention of the parties that the rates and terms of service specified herein shall remain in effect for the entire term set forth in this Article, and shall not be subject to change pursuant to the Federal Power Actabsent mutual agreement of the parties or as provided in section 3.4.


5
Section 3.4, in turn, provided for renegotiation "[i]n the event  that reasonably unforeseeable circumstances beyond the control of any party to this Agreement result in a gross inequity  to any party" and outlined a procedure for dispute resolution  in case parties fail to reach a new agreement.


6
APS submitted the three agreements for FERC approval  in March 1987.  See Monongahela Power Co., 39 F.E.R.C.  p 61,350, reh'g denied, 40 F.E.R.C. p 61,256 (1987).  In its  review of the filing, FERC noted that PEPCO represented  that "the rate levels are completely justified on the basis of  cost factors."  Id. at 62,093.  Also as recounted by FERC at  the time, PEPCO maintained that "once rates are determined  to be cost-justified, the noncost factors such as the potential  savings to PEPCO are superfluous, and the filing cannot be  deemed deficient even if the noncost support were deemed  insufficient."  Id.  FERC also noted that "[n]o party to [the]  proceeding has alleged that the rates under the three proposed agreements are unjust and unreasonable," and that  "[o]ur review indicates that the rates to PEPCO will not generate excessive revenues and should be accepted for filing  without suspension."  Id. at 62,096.  FERC accepted the  three contracts for filing to become effective June 1, 1987.See id. at 62,098.


7
In 1996, FERC issued the first in a series of orders known  collectively as "Order No. 888" to address problems associated with electric transmission monopolies in the bulk power  markets.  See Promoting Wholesale Competition Through  Open Access Non-Discriminatory Transmission Services by  Public Utilities, 61 Fed. Reg. 21,540 (1996), codified as  revised at 18 C.F.R. Pts. 35 & 385 (1999).1  The Order  required all public utilities that own, operate, or control  interstate transmission facilities to file an open access nondiscriminatory transmission tariff.  See id. at 21,540.  In its  open access transmission tariff ("OATT") proceeding pursuant to Order No. 888, APS agreed to charge a rate of $1.49  per kW-month for its transmission service, a rate substantially less than the rate PEPCO was obligated to pay under its  1987 agreement with APS.


8
Thereafter, PEPCO filed a complaint against APS, requesting that FERC summarily order APS to reduce the rate for  transmission services under the 1987 agreement to the same  level as APS's rate for comparable service under its OATT.  The Federal Power Act provides that electricity rates may be  modified in one of two ways:  under S 205, the seller may  attempt to prompt rate changes by filing a newrate schedule,  which will be reviewed by FERC to determine whether the  proposed rates are just and reasonable, see 16 U.S.C. S 824d,  and under S 206, FERC may reform the rates "upon its own  motion or upon complaint" if it determines the rates have  become "unjust, unreasonable, unduly discriminatory or preferential."  Id. S 824e(a).  PEPCO's request for a rate decrease, claiming that APS's rate was "excessive and unreasonable," asked FERC to exercise its authority under § 206 to  modify existing contracts and reduce the contractual transmission rate to the OATT rate.


9
APS moved to dismiss the complaint, citing section 9.3 of  the agreement under which the parties had agreed to eliminate the right of either party to initiate rate modification  pursuant to FERC's S 206 authority.  APS relied primarily  on the "Mobile-Sierra" doctrine, named after the two Supreme Court cases that established the "public interest"  standard for FERC review of electricity rates in contracts  restraining unilateral rate changes.  See United Gas Pipe  Line Co. v. Mobile Gas Serv., 350 U.S. 332 (1956);  Federal  Power Comm'n v. Sierra Pacific Power Co., 350 U.S. 348  (1956). Under the public interest standard of the MobileSierra doctrine, FERC has § 206 authority to modify rates  "fixed" by a Mobile-Sierra provision " 'where [the existing  rate structure] might impair the financial ability of the public  utility to continue its service, cast upon other consumers an  excessive burden, or be unduly discriminatory.' "  Papago  Tribal Util. Auth. v. FERC, 723 F.2d 950, 953 (D.C. Cir.  1983) (alteration in original) (quoting Sierra, 350 U.S. at 355);see also Metropolitan Edison Co. v. FERC, 595 F.2d 851, 855  (D.C. Cir. 1979).  In essence, APS maintained that PEPCO  failed to make the required showing under the Mobile-Sierra  doctrine that the public interest was adversely affected by the  existing contract.


10
In response, PEPCO asserted that the public interest was  adversely affected by the contractual rate because the excessive rates were entirely borne by its ratepayers.  PEPCO  also maintained that because of APS's market power, it had  little bargaining power at the time it entered the agreement  to influence the terms of the contract, including the MobileSierra provision in section 9.3.  Furthermore, PEPCO contended that the rate APS charged itself and others, approximately half of what PEPCO was being charged for the same  service, constituted undue discrimination prohibited under the  Mobile-Sierra doctrine.


11
FERC dismissed PEPCO's complaint.  See Potomac Elec.  Power Co. v. Allegheny Power Sys., 85 F.E.R.C. p 61,160  (1998).  Emphasizing that it "does not take contract modification lightly," FERC reasoned that the mere fact that PEPCO  was subject to higher rates under its agreement with APS  than it would be under APS's OATT was insufficient reason  for abrogating an agreement that PEPCO had fully supported at the time of filing and FERC had approved as just  and reasonable.  Id. at 61,632-33.  FERC also rejected PEPCO's request that it act sua sponte to reduce the rates for the  benefit of PEPCO's ratepayers, reasoning that it would be  inappropriate to convert PEPCO's unilateral request for reformation into a FERC-initiated contract modification where  the parties' agreement contained a Mobile-Sierra provision,  and where PEPCO had failed to satisfy the public interest  standard.  See id. at 61,633.


12
In denying PEPCO's petition for rehearing, FERC rejected PEPCO's contention that FERC had erred by failing to  assess whether the rates were just and reasonable, and  defined the issue instead to be whether the rates, having been  found to be just and reasonable when originally approved,  had become contrary to the public interest.  See Potomac  Elec. Power Co. v. Allegheny Power Sys. 87 F.E.R.C.  p 61,030, at 61,105 (1999).  FERC noted that, underits precedent, the fact that a contract has become uneconomic to one  of the parties does not necessarily make the contract contrary  to the public interest under the FPA.  FERC found no  reason to deviate from this precedent because PEPCO failed  to present any other ground for finding the agreement contrary to the public interest.  See id.  Responding to PEPCO's  argument that the contract was the result of uneven bargaining power and that FERC's failure to modify the rates rested  on its faulty assumption that PEPCO had willingly entered  into the agreement, FERC stated first, that PEPCO's contention was inconsistent with PEPCO's representations in 1987,  see id. at 61,106 n.10, and second, that FERC's decision was  based not on PEPCO's initial willingness to enter the agreement, but on PEPCO's failure to demonstrate that revising  the agreement was in the public interest.  See id. at 61,106.  Finally, in response to PEPCO's request that FERC follow  the approach it had adopted in Order No. 888 to allow  modification where rates are shown to be no longer just and  reasonable, FERC deemed the request misplaced because its  Order No. 888 Mobile-Sierra finding applied only to a discrete set of wholesale requirements contracts, not to transmission contracts like the one at issue.  See id. at 61,106 n.11.

II.

13
On appeal, PEPCO contends that by emphasizing only the  policies favoring fixed rate contracts and ignoring the FPA's  concerns with fairness and anti-competitiveness, FERC failed  to meet the FPA's mandate.  More specifically, PEPCO first  maintains that FERC's application of the Mobile-Sierra public interest standard ignored FERC's precedent calling for a  "flexible" version of the test in situations where FERC is  acting or is requested to act on behalf of non-party ratepayers that are affected by the contract.  Even if FERC applied  the correct "version" of the standard, PEPCO maintains  second that FERC failed to fulfill its obligation under the  public interest standard to ensure that the rates charged  under PEPCO's agreement with APS are neither unduly  discriminatory nor excessively burdensome on PEPCO's ratepayers.  Nor had FERC, PEPCO continues, taken into account that the agreement was the result of uneven bargaining  power, even though FERC had stated this factor was relevant  to a public interest analysis and had made a general finding  that transmission contracts entered into before Order No. 888  often reflected the exercise of market power.  In other  words, PEPCO submits, FERC acted arbitrarily and capriciously by not applying a flexible public interest standard and,  alternatively, by concluding that PEPCO had not met its  burden under the stringent Mobile-Sierra public interest  standard.


14
The court will uphold FERC's orders unless they are  "arbitrary, capricious, an abuse of discretion, or otherwise not  in accordance with law."  5 U.S.C. S 706(2)(A).  Likewise, the  court will uphold FERC's factual findings as long as they are supported by substantial evidence.  See 16 U.S.C. S 825l(b);see also Texaco, Inc. v. FERC, 148 F.3d 1091, 1095 (D.C. Cir.  1998) (citing Koch Gateway Pipeline Co. v. FERC, 136 F.3d  810, 814 (D.C. Cir. 1998)).  We hold that FERC's decision to  dismiss the complaint was not an unreasonable exercise of its  authority.


15
PEPCO concedes, implicitly in its briefs and explicitly at  oral argument, that the public interest standard set out in  Mobile and Sierra, and not the just and reasonable standard,  controls PEPCO's § 206 request.  The court has observed  that the Mobile-Sierra public interest standard is much more  restrictive than the FPA's "just and reasonable" standard,  see, e.g., Union Pacific Fuels, Inc. v. FERC, 129 F.3d 157,  161 (D.C. Cir. 1997);  San Diego Gas & Elec. Co. v. FERC,  904 F.2d 727, 730 (D.C. Cir. 1990), even characterizing the  burden under the public interest standard as "practically  insurmountable," Papago,723 F.2d at 954, and "almost insurmountable."  Kansas Cities v. FERC, 723 F.2d 82, 87-88  (D.C. Cir. 1983);  see also Tennessee Gas Pipeline Co., 60  F.E.R.C. p 61,318, at 62,104 (1992);  Central Maine Power  Co., 54 F.E.R.C. p 61,206, at 61,613-14 (1991).  PEPCO challenges such a restrictive characterization of the standard, and  contends that FERC was bound by its own precedent to  adopt an approach "less restrictive" than the Papago court's  phrase "practically insurmountable" suggests.


16
For this proposition, PEPCO relies on Northeast Utilities  Service Company, 66 F.E.R.C. p 61,332 (1994), aff'd 55 F.3d  686 (1995).  In Northeast Utilities, FERC, reviewing a rate  agreement in connection with a utility merger, modified a  fixed-rate contract "under the public interest standard required by the Mobile-Sierra doctrine."  Id. at 62,076.  In  modifying the contract, FERC rejected the proposition that  the Mobile-Sierra doctrine requires a generally applicable  standard that is so stringent as to be "practically insurmountable."  FERC explained:


17
[I]f the Commission is to comply with both the Mobile-Sierra imperative to respect contractual arrangements, on the one hand, and our statutory mandate to protect the public interest and ensure that rates are just and reasonable and not unduly discriminatory or preferential, on the other, the "public interest" standard of review under the Mobile-Sierra doctrine cannot be "practically insurmountable" in all cases.


18
Id. (footnote omitted) (quoting Papago, 723 F.2d at 954).  In  other words, FERC took the position that the court's characterization of the standard in Papago did not "preclude[ ] the  Commission from concluding in other circumstances that the  interests of third parties sufficiently outweigh the contracting  parties' interests in contract stability to justify the Commission's ordering contract modifications."  Id. at 62,086.  FERC  distinguished Papago on the basis that "Papago expressly  addressed rate changes, not the scope of the Commission's  authority upon its initial review of a newly-filed contract," id.,  and declared that in situations where it is reviewing a fixedrate agreement "for the first time, without having had any  previous opportunity to determine whether its terms are  lawful," a more relaxed public interest standard is warranted. Id. at 62,087.  The First Circuit affirmed.  See Northeast  Utils. Serv. Co. v. FERC, 55 F.3d 686, 692 (1st Cir. 1995).


19
FERC, in two subsequent cases that PEPCO also relies on,  reaffirmed its position in Northeast Utilities. In Southern  Company Services, Inc., 67 F.E.R.C. p 61,080 (1994), FERC  reiterated that "the public interest standard of review does  not bind the Commission to a practically insurmountable  burden in all cases in which the Commission might act to  change rates."  Id. at 61,227.  More specifically, FERC stated that the cases do not "impose a practically insurmountable  burden when the Commission proceeds sua sponte or at the  request of non-parties to change rates, terms and conditions  in order to protect non-parties to a contract."  Id. (citing  Northeast Utils., 66 F.E.R.C. at 62,081-88).  Similarly, in  Florida Power & Light Co., 67 F.E.R.C. p 61,141 (1994),  FERC stated, "when we are acting sua sponte or at the  request of non-parties to change rates, terms and conditions  in order to protect non-parties, we are not bound to a  standard of review that is practically insurmountable."  Id. at  61,399.


20
Thus, as PEPCO contends, FERC has at times expressed  an intent to apply a standard that is more flexible than the  "practically insurmountable" standard that Papago described. However, unlike the circumstances in which FERC has stated  it would apply a more flexible standard, PEPCO's § 206  request does not involve "the Commission proceed[ing] sua  sponte or at the request of non-parties to change rates ... in  order to protect non-parties to a contract."  Southern Co., 67  F.E.R.C. at 61,227;  see also Florida Power, 67 F.E.R.C. at  61,399.  PEPCO is not itself anon-party.  Nor did it offer  any evidence (beyond speculation) that the only potential nonparties here, its ratepayers, were adversely affected by the  existing rates;  it did not, for example, even attempt to show  how much if any of the rate disparity was passed on to  PEPCO ratepayers rather than borne by the utility itself. Nor does PEPCO's request involve a "newly-filed or previously unreviewed agreement."  Northeast Utils, 66 F.E.R.C.  at 62,087.2  FERC was clear in Northeast Utilities that it was  "not being asked to allow a party a unilateral rate change  from a fixed-rate contract whose terms [it] previously accepted," and that it was instead "reviewing the ... [c]ontract for  the first time, without having had any previous opportunity to  determine whether its terms are lawful."  Id.  As FERC  explained, applying the "practically insurmountable" standard  in first review cases would mean that "[its] ability to protect  the public interest would be negligible and public regulation  would consist of little more than rubber-stamping private  contracts."  Id.  By contrast, FERC had approved PEPCO's  1987 agreement with APS long before it was presented in  1998 with a complaint by one party to the agreement seeking a unilateral rate change.  The concerns that FERC raised in  Northeast Utilities with regard to applying the "practically  insurmountable" public interest standard when reviewing a  contract for the first time thus do not apply here.


21
The question remains whether FERC abused its discretion  in concluding that PEPCO failed to meet its burden under the  Mobile-Sierra public interest standard.  PEPCO contends  that FERC, in its public interest analysis, failed to consider  the excessive burden on PEPCO's ratepayers and the discriminatory impact of the disparity between the transmission  rates set by the 1987 agreement and APS's OATT transmission rate.  The problem with PEPCO's position is that, other  than pointing out that the contract rate is twice APS's OATT  rate, it has presented no evidence regarding how the contract  rates are unduly discriminatory or excessively burdensome on  PEPCO ratepayers.  The court has repeatedly emphasized  the importance of contractual stability in a number of cases  involving the Mobile-Sierra doctrine.  See, e.g., Maine Pub.  Serv. Co. v. FERC, 964 F.2d 5, 10 (D.C. Cir. 1992);  Cities of  Bethany v. FERC, 727 F.2d 1131, 1139 (D.C. Cir. 1984);Town of Norwood v. FERC, 587 F.2d 1306, 1313 (D.C. Cir.  1978).  Furthermore, the court has consistently stated that  rate disparity attributable to the operation of the MobileSierra doctrine is not on that basis alone unduly discriminatory.  See Maine Pub. Serv., 964 F.2d at 10;  Cities of Bethany,  727 F.2d at 1139, 1141;  Metropolitan Edison, 595 F.2d at 857  n.38;  Boroughs of Chambersburg v. FERC, 580 F.2d 573,  577-78 (D.C. Cir. 1978).  In addition, FERC precedent makes  clear that the fact that a contract has become uneconomic to  one of the parties does not necessarily render the contract  contrary to the public interest.  See Soyland Power Coop.,  Inc. v. Central Illinois Pub. Serv. Co., 51 F.E.R.C. p 61,004,  at 61,013 (1990);  Public Service Co., 43 F.E.R.C. p 61,469, at  62,152 (1988);  Gulf States Utils. Co. v. Southern Co. Servs.,  Inc., 43 F.E.R.C. p 61,003, at 61,014 (1988).  Considering such  precedent in favor of protecting contractual stability,  PEPCO's failure to provide any evidence of undue discrimination or excessive burden, other than the disparity in rates and  a bald claim that PEPCO ratepayers would derive benefit from a rate modification, renders its request wholly inadequate.  Therefore, FERC's summary dismissal of PEPCO'spublic interest argument was within its authority.


22
PEPCO also maintains that because of uneven bargaining  power in 1987, it did not necessarily enter into the fixed-rate  agreement with APS willingly.  However, PEPCO's willingness was not part of FERC's rationale for dismissing the  complaint.  FERC pointed out in denying rehearing:


23
The "premise" for the Commission's ruling is not that PEPCO willingly agreed to the Agreement's rates and terms.  Rather, the "premise" for the Commission's rul-ing is that contract modification is not to be taken lightly and that, in this case, PEPCO has failed to demonstrate that a revision to the Agreement is in the public interest.


24
PEPCO, 87 F.E.R.C. at 61,106 (footnote omitted).  Moreover,  PEPCO can hardly escape the consequences of the fact that  its statements to FERC in 1987 show that it fully supported  the fixed-rate agreement, see id. at 61,106 n.10, and that it  has not alleged bad faith negotiation on the part of the parties  to the agreement.  Nothing in the record on appeal demonstrates that the contract was the result of APS's market  power;  to the contrary, PEPCO has admitted that it had  other supply options when it entered the agreement with APS  in 1987.  See Monongahela Power Co., 39 F.E.R.C. at 62,092.While the existence of other options does not necessarily  mean an absence of market power, PEPCO's assertion to  FERC in 1987 that the transmission agreement was cost justified and represented cost savings over other supply  options supports such a conclusion.  Therefore, absent any  claim, much less evidence, of unfairness or bad faith in the  original negotiations, it is reasonable for FERC to require  parties "to live with their bargains as time passes and various  projections about the future are proved correct or incorrect."Norwood, 587 F.2d at 1312-13.


25
To the extent that PEPCO maintains that FERC's refusal  to modify the contract is inconsistent with Order No. 888-A,  it fares no better.  In Order No. 888-A, FERC found that,  prior to July 11, 1994, wholesale requirements contracts were "entered into during an era in which transmission  providers exerted monopoly control over access to their  transmission facilities," and that, as a result, "[m]any of  these contracts were the result of uneven bargaining power."  Order No. 888-A, FERC Stats. & Regs. p 31,048, at 30,193  (1997).  Accordingly, FERC concluded that it was in the  public interest to permit those requirements customers to  seek modification of their contracts under the just and reasonable standard, even if the contract contained a Mobile Sierra provision.  See id. at 30,189.  However, as PEPCO  concedes, Order No. 888-A's exception to application of the  Mobile-Sierra standard plainly applies only to requirements  contracts.  Moreover, as PEPCO again concedes, for nonrequirements contracts, such as the APS agreement, FERC  declined to extend its generic Mobile-Sierra findings to all  long-term block purchases of electricity.  See id. at 30,195.FERC distinguished these contracts from requirements contracts based on its conclusion that, in "the majority of circumstances, such long-term supply contracts are voluntary  arrangements in which neither party had market power."  Id.  FERC noted, "[p]arties can avail themselves of the  section 205 and 206 procedure already available if they want  to seek modification of such contracts."  Id.  That is what  PEPCO did here by requesting FERC to employ its S 206  authority, and FERC denied PEPCO's petition under the  Mobile-Sierra doctrine.  Therefore, FERC has precisely followed the procedure it outlined in Order No. 888-A.


26
It appears, then, that PEPCO's complaint is ultimately  directed at FERC's application of the Mobile-Sierra doctrine. PEPCO maintains that APS had monopoly power at the time  of the 1987 agreement and that FERC, "[h]aving expressly  offered buyers ... the opportunity to makesection 206 filings  to demonstrate that contracts that they previously had entered into were the subject of uneven bargaining power," has  an obligation to take APS's monopoly power into account in  its application of the Mobile-Sierra doctrine.  PEPCO's contention amounts to a claim that FERC's decision to loosen the  Mobile-Sierra standard for certain wholesale requirements  contracts is equivalent to a commitment on FERC's part to conduct a case-by-case inquiry into the presence and extent of  market power in every other non-requirement contract containing a Mobile-Sierra provision.  However, Order No.  888-A merely states that "[p]arties can avail themselves of  the section 205 and 206 procedures ... if they want to seek  modification," id., and does not say anything one way or the  other about the relevance of uneven bargaining power to the  standard Mobile-Sierra analysis.3  Besides, FERC's position  in Order No. 888-A was a carefully considered balance between "the desire to honor existing contractual arrangements" and "the need to provide some means to accelerate  the opportunity of parties to participate in competitive markets."  Id. at 30,192.  FERC continued, "To accomplish this  balance, the Commission ... has made Mobile-Sierra public  interest findings ... only as to a limited set of contracts: those wholesale requirements contracts executed on or before  July 11, 1994...."  Id.  Therefore, any request for FERC to  extend its Order No. 888-A exception for requirements contracts must be considered in light of the need for such a  balance, and nothing in Order No. 888-A obliges FERC to  strike the balance in the same way in all contexts.  While  PEPCO correctly points out that FERC's discussion of  PEPCO's No. 888-A contention is terse, see PEPCO, 87 F.E.R.C. at 61,106 n. 11, and the relevance of uneven bargaining power to the Mobile-Sierra analysis remains unclear,  PEPCO has failed to demonstrate that it was subject to  APS's monopoly power at the time it entered into the 1987  agreement.  Having presented no evidentiary detail that  might have compelled FERC to consider whether, by analogy, it should extend its Order No. 888-A public interest  findings on a case-by-case basis to non-requirements contracts possibly involving relevantly similar factual circumstances, PEPCO fails to show that FERC's summary dismissal was unreasonable.


27
Ultimately, PEPCO's case suffers from a failure of proof. PEPCO's counsel explained at oral argument that PEPCO  did not seek a hearing before FERC on its § 206 complaint  because PEPCO considered its allegations regarding the impact of the 1987 agreement on its ratepayers to be unrebutted.  The court strains, in light of precedent, to imagine how  PEPCO could conclude that it did not have a burden to offer  evidence on this and other relevant factual issues, such as  whether and the extent to which the agreement rates adversely impact PEPCO's ratepayers and whether APS had  market power at the time the 1987 agreements were signed.  PEPCO's position would undoubtedly have been strengthened  had there been evidence in the record to support the assertions in its briefs regarding the asserted impact on ratepayers  and APS's market power, although we express no opinion on  the outcome under those circumstances.


28
In sum, given the practically insurmountable standard that  it faced, PEPCO was obligated to do more than point to the  disparity between the agreement rates and the rates it would  pay under the APS open access tariff.  FERC reasonably  concluded that PEPCO failed to demonstrate that the APS  rates in the 1987 agreement are contrary to the public  interest.  While FERC retains the statutory authority and  duty to correct or prevent an electric rate schedule that  " 'might impair the financial ability of the public utility to  continue its service, cast upon other consumers an excessive  burden, or be unduly discriminatory,' " Papago 723 F.2d at  953 (quoting Sierra, 350 U.S. at 355), it acted within its  discretion to conclude from the face of the complaint that the rates in the previously approved agreement that PEPCO fully  supported and claimed was justified were not contrary to the  public interest.

 This court has not had occasion to address, and need not do so  here, whether FERC has authority to apply a Mobile-Sierra standard that is more flexible than the "practically insurmountable"  standard whenever it reviews a "newly-filed or previously unreviewed agreement," Northeast Utils, 66 F.E.R.C. at 62,087, or  "proceeds sua sponte or at the request of non-parties to change  rates ... in order to protect non-parties to a contract."  Southern  Co., 67 F.E.R.C. at 61,227;  see also Florida Power, 67 F.E.R.C. at  61,399.

 In fact, at least one circuit court has expressed skepticism  about the relevance of uneven bargaining power in Mobile-Sierra  analysis.  The First Circuit stated:
As for the seller's market power, reliance on this factor threatens to erode the Mobile-Sierra doctrine so substantially that a fuller explanation from the Commission is required before proceeding down this route.  After all, some measure of market power could be present in a large number of contracts.  A case-by-case inquiry into the presence and extent of market power would inject a new and potentially time-consuming element into the Mobile-Sierra analysis, and it is not entirely clear in any event why the Commission should protect a buyer who voluntarily enters into an agreement with a dominant seller. Northeast Utils. Serv. Co. v. FERC, 993 F.2d 937, 961 (1st Cir. 1993).
