Opinion for the Court filed by Circuit Judge SENTELLE.
Nine utility members of the Pennsylvania-New Jersey-Maryland Interconnection (hereinafter “utility petitioners”))
I. Background
A. Statutory and Regulatory • Framework
Section 201(b) of the Federal Power Act confers upon FERC jurisdiction over all rates, terms, and conditions of electric transmission service provided by public utilities in interstate commerce, as well as over the sale of electric energy at wholesale. 16 U.S.C. § 824(b). Under section 205 of the Act, the Commission is obliged to assure that the rates and charges demanded or received by any public utility in connection with the interstate transmission or sale of electric energy are just and reasonable, and that no public utility’s rates will unduly discriminate against any consumers. Id. § 824d(a), (b); see NAACP v. Federal Power Comm’n,
“Historically, electric utilities were vertically integrated, owning generation, transmission, and distribution facilities and selling these services as a ‘bundled’ package to wholesale and retail customers in a limited geographical service area.” Public Utility Dist. No. 1 of Snohomish Co. v. FERC,
B. The PJM Interconnection
The Pennsylvania-New Jersey-Maryland (“PJM”) Interconnection is a tight power pool. See Order No. 888,
In response to Order No. 888 the PJM members submitted to FERC in 1996 an open access tariff and several negotiated agreements that proposed to revise the PJM governance structure to put in place an ISO. The utility petitioners filed the tariff and ISO agreement under section
C. FERC Proceedings
FERC asserted jurisdiction over the PJM restructuring under section 203, ruling that the proposal to transfer operational responsibilities to the ISO is a “disposition of jurisdictional facilities” within the meaning of section 203, requiring FERC authorization. Atlantic City Elec. Co., 76 F.E.R.C. ¶ 61,306, at 62,513,
In its November 13, 1996 order on the merits, FERC recognized that formulating an acceptable ISO was a difficult task, but found that the restructuring proposal did not conform with the ISO principles set out in Order No. 888. See Atlantic City Elec. Co., 77 F.E.R.C. ¶ 61,148, at 61,559,
The Transmission Owners Agreement provided that the utility owners would offer pool-wide transmission service, and would transfer the administration of the tariff and regional transmission planning and operations to the PJM-OI as the ISO. The Agreement established procedures for changes to rate design and other tariff terms for ■ transmission services. It permitted the transmission owners to file changes in transmission service rate design and non-rate terms and conditions to the tariff under section 205. However, the independent PJM Board could reject a
FERC found that the revised proposal generally satisfied its ISO principles, and, subject to certain modifications, conditionally approved the ISO structure. Pennsylvania-New Jersey-Maryland Interconnection, 81 F.E.R.C. ¶ 61,257,
FERC also prohibited the withdrawal of utilities from the ISO without preclearance from the Commission. Despite finding that the PJM Board possessed “the requisite indepéndence from the transmission owners,” id. at 62,263, FERC suggested that members might exereisé “implicit” control over the Board by terminating membership. FERC directed the petitioners to modify the restructuring agreements to clarify that “any notice of termination or withdrawal from the agreements must be filéd with the Commission and may become effective only upon the Commission’s ’approval.” Id. at 62,265 (emphasis in original). ’ Thus the “90-day withdrawal right is effective only upon the Commission’s approval.” Id. at 62,279 (emphasis in original).
Finally, the Commission ordered the transmission owners to modify any agreements under which they provided transmission service to eliminate multiple transmission charges and to reflect that PJM-OI administers those agreements. Id. at 62,280-81. Similarly FERC required the modification of any existing bundled wholesale power sales agreements that were inconsistent with the restructured PJM transmission rate arrangements. This modification was to eliminate charges that the utility owners no longer had to pay. Id. at 62,281-82. One agreement affected by these requirements is PSE&G’s bundled wholesale agreement with the Old Dominion Electric Coopera

II. Analysis
As a federal agency, FERC is a “creature of statute,” having “no constitutional or common law existence or authority, but only those authorities conferred upon it by Congress.” Michigan v. EPA,
“To determine whether the agency’s action is contrary to law, we look first to determine whether Congress has delegated to the agency the legal authority to take the action that is under dispute.” Michigan,
Indeed, “[ajgency authority may not be lightly presumed. ‘Were courts to presume a delegation of power absent an express withholding of such power, agencies would enjoy virtually limitless hegemony, a result plainly out of keeping with Chevron [, Mead,] and quite likely with the Constitution as well.’ ” Michigan,
With this standard in mind, we turn to the case at bar: First we consider whether FERC had authority to require the utility petitioners to give up them statutory rights under section 205 and determine it did not. Second we examine whether section 203 confers authority on FERC to require petitioners to modify the ISO agreement to allow withdrawal only upon approval by the Commission, and conclude it does not. Finally, we find that FERC’s requirement that preexisting wholesale power contracts be modified was contrary to law under the Mobile-Sierra doctrine.
A. Section 205 Rights
Section 205 of the Federal Power Act gives a utility the right to file rates and terms for services rendered with its assets. 16 U.S.C. § 824d. The PJM members had voluntarily proposed a sharing arrangement on changes to rate design that attempted tp balance the utility owners’ rights and the ISO Board’s independence. FERC disapproved this sharing arrangement and directed the utility petitioners to give up all authority to make unilateral changes to rate design. Petitioners contend that FERC lacks the authority to. require the utility owners to give up their statutory rights under section 205. We agree.
FERC cannot point to any statute giving it authority for its unprecedented decision to require the utility petitioners to cede rights expressly given to them in section 205 of the Federal Power Act. FERC finds no authority in section 205. Indeed, quite the contrary. FERC is attempting to deny the utility petitioners the very statutory rights given to them by Congress. Section 205(d) provides that a public utility may file changes to rates, charges, classification, or service at any time upon 60 days notice. Id. § 824d(d). FERC can then review those changes under section 205 and suspend them for a period of five months, but it can reject them only if it finds that the changes proposed by the public utility are not “just and reasonable.” Id. § 824d(e); see Cities of Campbell v. FERC,
Similarly, nothing in section 206 sanctions denying petitioners their right to unilaterally file rate and term changes. Section 206 merely permits the Commission — acting either on its own initiative or after a complaint — to initiate changes to existing utility rates and practices. In order to make any change in an existing rate or practice, FERC must first prove that the existing rates or practices are “unjust, unreasonable, unduly discriminatory or preferential.” 16 U.S.C. § 824e(a); see Alabama Power Co. v. FERC,
The courts have repeatedly held that FERC has no power to force public utilities' to file particular rates unless it first finds the existing filed rates unlawful. See Pub. Serv. Comm’n v. FERC,
Of course, utilities may choose to voluntarily give up, by contract, some of their rate-filing freedom under section 205.
B. FERC Jurisdiction Under Section 203
The utility petitioners argue that FERC erred in directing them to modify their ISO agreements to require Commission approval prior to a utility’s withdrawal from the ISO under section 203 of the Act. Section 203 provides: “No public utility shall sell, lease, or otherwise dispose of’ jurisdictional facilities whose value exceeds $50,000 “without first having secured an order of the Commission authorizing it to do so.” 16 U.S.C. § 824b(a) (emphasis added). FERC contends that the formation of the ISO is a “dispos[ition]” of facilities within the meaning of section 203, thus giving the Commission jurisdiction under that section. We disagree. A utility does not “sell, lease, or otherwise dispose” of its facilities when it agrees to the changes in operational control necessary to initially join or to withdraw from an ISO. Therefore FERC exceeded its jurisdiction by directing the utility petitioners to modify their agreement to state that any notice of withdrawal from the ISO shall become effective only upon FERC approval.
When the utilities joined the PJM ISO there was no transfer of ownership or even physical operation of their facilities. Pursuant to the operating agreement, each of the utilities retained both ownership and physical control of their facilities, but gave to the PJM ISO certain operational responsibilities relating to the provision of transmission services using their jurisdictional facilities. Thus, when a PJM member withdraws, there is again, no change in ownership, and no grounds for FERC to require preapproval under section 203. FERC contends that the word “dispose” in section 203 can be construed broadly to include the transfer of supervisory opera
First, the terms “sell” and “lease” in section 203 clearly contemplate a transfer of ownership or proprietary interests. Id. The expression “otherwise dispose” requires a similar interpretation under the principle noscitur a sociis. See Dole v. United Steelworkers of America,
Second, FERC’s expansive reading of its section 203 jurisdiction cannot be reconciled with section 202, which has been definitively interpreted to make clear that Congress intended coordination and interconnection arrangements be left to the “voluntary” action of the utilities. See 16 U.S.C. § 824a(a). Section 202 provides that “the Commission is empowered and directed to divide the country into regional districts for the voluntary interconnection and coordination of facilities for the generation, transmission, and sale of electric energy.” Id. (emphasis added). That provision does not provide FERC with any substantive powers “to com/pel any particular interconnection or technique of coordination.” Duke Power Co. v. Federal Power Comm’n,
Third, prior to this case this Commission held a similar view of the limits of its own jurisdiction under section 203. It observed that “Section 203 was ... designed to insure that transfers of utility property to, as well as from, the companies subject to our jurisdiction would be in the public interest.” Duke Power Co., 36 F.P.C. 399, 402 (1966) (emphasis added), rev’d on other grounds, Duke Power Co. v. Federal Power Comm’n,
FERC’s supporting intervenors argue that the transfer of operational control over jurisdictional facilities to the ISO is a “disposition” within the meaning of section 203. Similarly, in the Jurisdictional Order, FERC noted that “the creation of an ISO requires the transfer of control of the operation of the PJM transmission facilities from the transmission owners ... to the ISO and is a disposition of jurisdictional facilities requiring prior Commission authorization under section 203.” 76 F.E.R.C. at 62,513. Yet, FERC did not rely on this analysis in its brief before this Court, and with good reason. In the proceedings below, the Commission found that the PJM power pool was already “operated” on a coordinated basis, with a central dispatch, “by an independent staff referred to as the PJM Office of Interconnection (PJM-OI).” PJM-Restructuring Order, 81 F.E.R.C. at 62,234 n.l. Prior to the attempt to create an ISO, FERC never asserted section 203 jurisdiction over the PJM tight power pool. The “operational control” exercised by the ISO is no different from that of its predecessor power pool-. The distinction suggested by the intervenors, that the PJM utilities are transferring control to an independent ISO rather than a member-controlled tight power pool, is a very thin reed. Moreover, although the ISO would exercise supervision over the daily scheduling and dispatching activities of the network facilities, the participating members would retain physical control and ownership of the transmission facilities and be responsible for their maintenance. The transmission owners would merely transmit energy in accordance with the directives of the ISO. Public utilities make decisions about the operational control of their facilities on a regular basis. They give customers the right to demand capacity, they enter into coordination agreements, and they join together in cooperative ventures that require common management. Yet, for more than half a century, section 203 has never been construed to give the Commission control over every such agreement. Its focus is plainly upon the disposition of the facilities themselves. As “[a]gency authority may not be lightly presumed,” Michigan,
C.- Generic Modification of Contracts
Finally we turn to PSE&G’s challenge to FERC’s order requiring the generic reformation of pre-existing wholesale power
Prior to the formation of the PJM ISO, transmission service was (and in most parts of the country, still is) sold on a utility-by-utility basis. If a power sale required transmission service over the lines of more than one utility to travel on a path from the power plant to the buyer, transmission service would be purchased separately from each intervening utility. Under the Commission’s ISO guidelines set forth in Order No. 888, the transmission lines of all of the utilities that-join an ISO are to be pooled together and sold for a single rate, even when a transaction uses the transmission lines of more than one utility. In Order No. 888 and its progeny, FERC indicated that the new transmission pricing rules were to apply prospectively only. Pre-existing contracts would be left unchanged, unless the parties voluntarily agreed to an amendment or the customer proved, on a case-by-case basis, that the facts presented by an individual contract justified a change. See Order No. 888,
Under the Mobile-Sierra doctrine FERC may abrogate or modify freely negotiated private contracts that set firm rates or establish a specific methodology for setting the rates for service, and deny either party the right to unilaterally change those rates, only if required by the public interest. Texaco Inc. v. FERC,
FERC claims to have engaged in a fact-specific inquiry in a section 206 complaint brought by Old Dominion. See Old Dominion Elec. Coop. v. Public Serv. Elec. &
Despite FERC’s bald assertion that the transmission rate under the PSE&G — Old Dominion 1992 agreement was “unreasonable” or “discriminatory,” this case involves little more than a party to a contract seeking to avail itself of a lower rate than it was entitled to under the terms of its original agreement. This Court has consistently held, however, that a rate differential attributable to the operation of the Mobile-Sierra doctrine, is not, by itself, enough to demonstrate that the public interest demands a modification to or an abrogation of an existing contract. See, e.g., Potomac Elec.,
III. Conclusion
FERC has attempted to exert authority where it has none. FERC can point to no statute authorizing its requirement that the utility petitioners cede their statutory rights under section 205 of the Federal Power Act to file changes in rate design with the Commission. Nor does FERC have jurisdiction under section 203 of the Act to require the utility petitioners to modify the ISO agreement to allow withdrawal only upon approval by the Commission. A utility does not “sell, lease, or otherwise dispose” of facilities when it agrees to the changes in operational control necessary to withdraw from (or initially join) an ISO. Finally, FERC’s requirement of generic reformation of pre-existing wholesale power contracts, without making a particularized finding that the public interest requires modification of a particular agreement, is a violation of the Mobile-Sierra doctrine. Therefore,' we grant the petitions for review, vacate those portions of the Jurisdictional Order, PJM Restructuring Order, and the Compliance Order that are inconsistent with this opinion, and remand for further proceedings.
So ordered.
