574 F.2d 610 | D.C. Cir. | 1978
Opinion for the Court filed by SPOTTSWOOD W. ROBINSON, III, Circuit Judge.
We are presented here with disputes arising from attempts by the Federal Power Commission
I. INTRODUCTION
To counteract oil shortages threatened by the embargo, the Commission on November 29.1973, implored the Nation’s electric utilities to make maximum use of other fuels.
Concerned by forecasts of dire oil shortfalls and apparently doubting the efficacy of the voluntary program, the New England Power Pool (NEPOOL)
The Commission’s staff expressed its approval of the rates. Conceptualizing “fuel conservation service” as a series of transfers scheduled on a weekly or slightly longer basis, the staff recommended that the rate structure resemble those frequently employed for short-term power, including recovery of the replacement cost of fuel, incremental operating costs (variable costs) and a pro rata share of fixed costs (constant costs). The staff concluded that the rates were reasonable as measured by that standard.
Richmond (Indiana) Power & Light, an electric utility, and Representative Michael J. Harrington of Massachusetts
By order of August 26,1974, the Commission determined that the situation did not justify invocation of its emergency powers and granted NEPOOL’s motion to withdraw its petition.
II. THE COAL-BY-WIRE PROGRAM
A. NEPOOL’s Petition for Emergency Relief
We must first analyze the Commission’s decision to allow NEPOOL to withdraw its petition for emergency relief. Richmond is aggrieved by the Commission’s refusal to invoke Section 202(c)
We encounter little difficulty in concluding that the Commission was well within its discretion. Richmond argues that NE-POOL never received all of the coal by wire it had originally requested and, although the embargo has long since ended, that the high cost and uncertain supply of imported oil continue to justify emergency measures. On the first point, the Commission pointed out that because the effects of the embargo
Richmond’s second contention, that dependence on imported oil leaves this country with a continuing emergency, compels no different result. We are fully mindful, of course, that current national policy is to discourage reliance on foreign oil, but we cannot fault the Commission for reading Section 202(c) as devoid of a solution. That section speaks of “temporary” emergencies, epitomized by wartime disturbances,
B. The Necessity of Considering National Policy On Foreign Oil
Richmond’s major complaint is that the Commission erroneously limited the scope of its inquiry. The Commission explained its position in these words:
These proceedings are not ones in which we are properly called upon to resolve broad questions of resource allocation, industry pooling structures and operating procedures, all as raised by the foregoing contentions. These fuel conservation power and energy transfers were consummated at the Commission’s request to meet physical fuel shortfall conditions, not to affect economic conditions. The Commission contemplated that these transfers would be accomplished within the framework of the existing power pools and electric reliability councils.20
Since displacement of foreign oil with domestic energy is a national goal, Richmond
We disagree. Although the Commission must serve the public interest in approving rates, we see no abuse of discretion in limiting this proceeding to the shortrun problem of setting just and reasonable rates for the service theretofore provided in response to the 1973 oil embargo. While an administrative agency must remain faithful to public policies directly related to its regulatory authority
The goal of minimal use of foreign oil is predicated upon fear of overdependence and the concomitant danger of economic dislocation by an actual or threatened cutoff. This very dispute demonstrates, however, that as long as substantial excess capacity remains available in an emergency— and Richmond does not propose any lasting dedication of capacity — the Commission by order or by persuasion can eliminate much of the need for oil in electrical generation. Thus the question of long-term displacement of imported petroleum could safely be left to later proceedings instigated by Richmond or the Commission itself, or indeed to resolution by Congress.
Moreover, while the Commission rebuffed a more positive march toward the goal of decreased consumption of foreign oil, it also rejected the means suggested by Richmond for achieving' that end as either inefficacious or statutorily prohibited. If that action was well founded, the Commission’s failure to weigh the requested objective could hardly amount to error.
C. Through Rates
Richmond’s most imaginative demand was that the Commission modify the proposed schedules by the substitution of “through” transmission rates for coal-by-wire transactions. An understanding of this proposition requires some knowledge of the national electrical interconnection system, and thus we offer a brief explanation.
The United States is divided into a number of regions for purposes of interconnection.
Such transfers normally occur at night or on weekends, when suppliers are more likely to have underused turbines and power lines. Traditionally, and under the schedules approved by the Commission, each utility or pool pays its neighbor for the service provided; a particular coal-by-wire transmission can involve four or more individual charges. If no supplier can be found or any needed intervening utility refuses to wheel, the entire transmission will fail. Quite understandably, no one lacking excess capacity is generally disposed to give power up until assured of a replacement amount from someone else.
Moreover, as Richmond admits,
D. Authority to Require Wheeling
No one now argues that the Commission has authority to mandate wheeling. As the Supreme Court recently held, the legislative history precludes that result:
As originally conceived, Part II [of the Federal Power Act] would have included a “common carrier” provision making it “the duty of every public utility to . transmit energy for any person upon reasonable request. . . .’’In addition, it would have empowered the Federal Power Commission to order wheeling if it found such action to be “necessary or desirable in the public interest.” H.R. 5428, 74th Cong., 1st Sess.; S. 1725, 74th Cong., 1st Sess. These provisions were eliminated to preserve “the voluntary action of the utilities." S.Rep.No.621, 74th Cong., 1st Sess., 19.
It is clear, then, that Congress rejected a pervasive regulatory scheme for controlling the interstate distribution of power in favor of voluntary commercial relationships.32
As we have indicated, both Richmond and Representative Harrington originally urged the Commission to directly order wheeling.
In this court Richmond seeks the same end through less direct mearis. Since the Commission may reject unreasonable rate proposals and fix acceptable rates instead,
Richmond assumes that the proffered rates were unreasonable because they did not guarantee that utilities will wheel. Yet Congress’ as-yet unamended purpose was to indulge utilities that very freedom.
E. Recovery of Fixed Costs
On more traditional grounds, Richmond attacks the inclusion of fixed costs in the Commission’s transmission rate calculations.
Richmond’s contentions obviously would be doomed to failure had it succeeded in persuading the Commission to develop long-term fuel conservation measures featuring mandatory wheeling. Had that been done, and once such transfers became commonplace, utilities expectably would build new facilities to assure an adequate safeguard of excess capacity for their regular customers;
Without debating the logic behind the inclusion of fixed costs in situations of this sort, we must say that in this case the Commission has reached an informed and reasoned decision.
Although the utilities could cancel out on short notice, coal-by-wire service involved reservations of identifiable facilities.
To summarize, we find that substantial evidence supports the Commission’s actions and that the rates approved fall within the statutorily-mandated zone of reasonableness.
III. DISCRIMINATION
One last and analytically separate issue remains. Richmond has used
With contract negotiations ongoing between Richmond and I&M, the Commission’s order of August 26,1974, referred the dispute to the Department of Justice and the Securities and Exchange Commission, and concluded that the parties should reconsider their positions in light of its rulings on Richmond’s other contentions.
Richmond’s only response was to argue that
[t]he Commission has failed, and is failing, to order relief for Richmond which would assure that I&M will in fact purchase Richmond energy on a non-discriminatory basis, that I&M will provide transmission service for Richmond’s available energy not purchased by I&M, and that I&M will sell to and transmit to Richmond conservation energy in the event of a coal shortage, at least on the same basis it provides such services to other utilities, and on the same basis such services are supplied among and between the AEP affiliates.56
Thus Richmond spurned the opportunity to demonstrate that particular activities were unreasonably anticompetitive or discriminatory and claimed instead that the mere failure to wheel energy to and from Richmond while wheeling for any other utility was unlawful discrimination.
Had Richmond made such a presentation, we would still be far from certain that the Commission’s deferral of further consideration to a separate proceeding would have been error. Agencies have wide leeway in controlling their calendars,
IV. CONCLUSION
Although the objectives that Richmond has sought to realize in this ratemaking proceeding may have some merit, we remain convinced that on the whole the Commission dealt with them in a manner consistent with its statutory discretion. We are not at liberty to substitute our judgment for the judgment of the Commission. The orders reviewed herein must accordingly be affirmed.
So ordered.
. The powers and duties of the Federal Power Commission were transferred to' the Federal Energy Regulatory Commission as of October 1, 1977. Department of Energy Organization Act, 42 U.S.C.A. 7171-7177, 7295(c) (West Supp. Nov. 1977). Because the events relevant to this case occurred before that time, we will continue to refer to the Federal Power Commission in this opinion.
. Nation-Wide Fuel Emergency (Order No. 496), 50 F.P.C. 1691 (1973).
. NEPOOL is a group of interconnected independent electric utilities. Power pools of this sort are described in text infra at note 28.
. Experts distinguish between power, for which the utility receives reimbursement for fixed and all other costs, and energy, for which the utility is reimbursed only for fuel and variable costs. We do not limit our use of these terms to such technical understandings.
. 16 U.S.C. § 824a(c) (1970), quoted infra note 17.
. The Congressman purported to act on behalf of himself and his constituents, all potentially affected by coal-by-wire rates. For convenience, we shall more often refer to both Representative Harrington and Richmond Power & Light as “Richmond” even though each did not join in every contention with which we must deal.
. No party has challenged the propriety in this instance of determining rates through rulemaking: Cf. FPC v. Texaco, Inc., 417 U.S. 380, 94 S.Ct. 2315, 41 L.Ed.2d 141 (1974) (rulemaking proper for setting rates under the Natural Gas Act).
. Some pools voluntarily proposed through rates for transmissions cutting across the areas respectively served by their component utilities. Richmond, however, sought such rates for the entire transmission from the supplier to the ultimate recipient — not just for some portions of the journey.
. Wheeling is broadly defined as the “transfer by direct transmission or displacement [of] electric power from one utility to another over the facilities of an intermediate utility.” Otter Tail Power Co. v. United States, 410 U.S. 366, 368, 93 S.Ct. 1022, 1025, 35 L.Ed.2d 359, 363 (1973). Because electricity in an activated system is always flowing, the transfer can be made by adding to the flow in one direction— true wheeling — or, if the transfer is in the opposite direction of the then-prevailing flow, by reducing the flow from the receiving to the supplying utility by the amount required — displacement.
For convenience, we will usually refer to all “intermediate” utilities as “transmitting” utilities and to their service as “transmission.” Similarly, we will refer to the end seller as the “supplier.”

(c) During the continuance of any war in which the United States is engaged, or whenever the Commission determines that an emergency exists by reason of a sudden increase in the demand for electric energy, or a shortage of electric energy or of facilities for the generation or transmission of electric energy, or of fuel or water for generating facilities, or other causes, the Commission shall have authority, either upon its own motion or upon complaint, with or without notice, hearing, or report, to require by order such temporary connections of facilities and such generation, delivery, interchange, or transmission of electric energy as in its judgment will best meet the emergency and serve the public interest. If the parties affected by such order fail to agree upon the terms of any arrangement between them in carrying out such order, the Commission, after hearing held either before or after such order takes effect, may prescribe by supplemental order such terms as it finds to be just and reasonable, including the compensation or reimbursement which should be paid to or by any such party.

Tallman, 380 U.S. 1, 16, 85 S.Ct. 792, 801, 13 L.Ed.2d 616, 625 (1965) (courts must yield “great deference to the interpretation given [a] statute by the officers or agency charged with its administration”) with Barlow v. Collins, 397 U.S. 159, 166, 90 S.Ct. 832, 837, 25 L.Ed.2d 192, 199 (1970) (meaning of statutory terms must ultimately be resolved by courts and not by agencies).
In view of our conclusion that the Commission did not abuse its discretion by refusing to declare a § 202(c) emergency, we have no occasion to address the Commission’s argument that such decisions are committed to agency discretion by statute and thus are judicially unreviewable.
. New England Power Pool Participants, Coaiby-Wire, supra note 10, 52 F.P.C. at (U9-420 (Order of Aug. 26, 1974). In initiating the coal-by-wire effort, the Commission stated:
The Commission does not view these requested actions as permanent long-term or in substitution for increased supplies of electric*405 power and energy generated from non-petroleum and non-natural gas fuels. They are temporary expedients to meet current national fuel and energy conditions.
Nationwide Fuel Emergency (Order No. 496), supra note 2, 50 F.P.C. at 1694.
. Richmond did not seriously argue that the Commission should completely abandon such considerations as cost and instead set the rates at a level designed solely to assure transmission of a substantial amount of coal by wire. Thus we need not determine whether, under the Federal Power Act and the Fifth Amendment, the Commission could ever fix rates below allocable costs simply to further particular end uses or policies. Compare FPC v. Hope Natural Gas Co., 320 U.S. 591, 617, 64 S.Ct. 281, 294-295, 88 L.Ed. 333, 353 (1944) (“[i]f the standard of ‘just and reasonable’ is to sanction the maintenance of high rates ... because they restrict the use of natural gas for certain purposes, the Act must be further amended”) and Consolidated Gas Supply Corp. v. FPC, 172 U.S.App.D.C. 162, 168, 520 F.2d 1176, 1184 (1975) (“we need not and do not rule on [the Commission’s] authority to discourage end use when prescribing rates in a shortage situation”).
. Although we need not resolve the issue, one may doubt whether the goal of energy independence is within the Commission’s regulatory jurisdiction at all. In NAACP v. FPC, the Court ruled that, although elimination of employment discrimination is “an important national goal,” the Commission is not called upon to “advanc[e] the public interest in general”; “the use of the words ‘public interest’ in a regulatory statute is not a broad license to promote the general public welfare. Rather, the words take meaning from the purposes of the regulatory legislation.” 425 U.S. 662, 665-666, 669, 96 S.Ct. 1806, 1809-1810, 1811, 48 L.Ed.2d 284, 288-289, 291 (1976). The Commission’s principal purpose, the Court reminded, is the “orderly development of plentiful supplies of electricity and natural gas at reasonable prices.” Id. at 670, 96 S.Ct. at 1811, 48 L.Ed.2d at 291 (footnote omitted).
Richmond does not argue for overall conservation of fuel, but instead urges that utilization of one fuel is preferable to another. Nor is there room in this case for argument that the Commission must encourage coal by wire because it bears more reasonable prices than does foreign oil. It would be circular to say that the Commission must consider setting low rates for coal by wire because if it does they will be below rates reflecting the cost of an equivalent amount of foreign oil.
Perhaps the answer is that the Commission may consider the energy-independence issue but, aside from its future relationship to potentially lower rates, is not necessarily required to do so. All the Act expressly mandates is that the Commission determine whether the rates are unjust, unreasonable or unduly discriminatory. Federal Power Act §§ 205-206, 16 U.S.C. §§ 824d-824e (1970). Another section of the Act, not directly applicable to this proceeding, deals with the Commission’s duty to promote and encourage voluntary interconnection, and states that its purpose is to assure “an abundant supply of electric energy throughout the United States with the greatest possible economy and with regard to the proper utilization and conservation of natural resources . . .” Id. § 202(a), 16 U.S.C. § 824a(a). From this expression of congressional intent, one might reason that the Commission is empowered to consider overall fuel-supply economics and the social consequences of energy shortages, but that it need not invariably do so if the rates are just and reasonable in the traditional regulatory sense and if the rate decision will not substantially impair the chances for achieving the goals of § 202(a) through the mechanisms of that section.
Nothing in NAACP v. FPC, supra, forecloses agency discretion to consider in given situations pervasive public policies that it is not required to evaluate in every decision it makes. But see Kennedy, The Federal Power Commission, Job Bias and NAACP v. FPC, 10 Akron L.Rev. 531, 537 (1977). If it is within an agency’s discretion to consider furthering an asserted public interest, but if consideration of that interest is not demanded by the governing regulatory legislation, compare, e. g., Scenic Hudson Preservation Conference v. FPC, 354 F.2d 608, 614, 620 (2d Cir.), cert. denied, 384 U.S. 941, 86 S.Ct. 1462, 16 L.Ed.2d 540 (1965) (“[t]he Commission has an affirmative duty to inquire into and consider” all facts relevant to the decisionmaking standards imposed by the
The Commission rejected a less circular argument — that it should do more to encourage coal by wire because it was less costly than foreign oil — on the ground that, with “decreasing fuel inventories and escalating prices for coal,” coal by wire “did not materialize in 1974 as a source of low-cost ‘non-emergency’ power and energy for New England.” New England Power Pool Participants, Coal-by-Wire, supra note 13, at 20 (Order of Sept. 26, 1975), J.App. 955. This conclusion was within the Commission’s expertise and was supported by undisputed data in the record. Richmond’s present argument differs in that it proposes that the Commission should set rates low, even below cost, simply on the ground that they would therefore be low.
. Cf. City of Lafayette v. SEC, 147 U.S.App.D.C. 98, 110, 454 F.2d 941, 953 (1971), aff’d, 411 U.S. 747, 93 S.Ct. 1870, 36 L.Ed.2d 635 (1973) (discussing “the requirement of a reasonable nexus between the activities challenged and the activities furthered by the application”).
. NOW v. FCC, 181 U.S.App.D.C. 65, 74, 555 F.2d 1002, 1011 (1977) (“industry-wide problem may be more appropriately aired and an industry-wide remedy formulated in a general inquiry”); see note 60 infra and accompanying text. For example, in Aberdeen & R. R. R. v. SCRAP (SCRAP II), 422 U.S. 289, 95 S.Ct. 2336, 45 L.Ed.2d 191 (1975), the Supreme Court noted that “standard ratemaking criteria limit the power of the [Interstate Commerce Commission] to force railroads to transport recyclable materials at deficit rates no matter how much the environment would be benefited thereby . . . Id. at 323 n.21, 95 S.Ct. at 2357 n.21, 45 L.Ed.2d at 217 n.21. And the Court went on to conclude that “no purpose could have been served by ordering [the Commission] to thoroughly explore the question in the confined and inappropriate context of a railroad proposal for a general rate increase when it was already doing so in a more appropriate proceeding.” Id. at 325, 95 S.Ct. at 2358, 45 L.Ed.2d at 218.
. We note that the question whether long-term usage of fuel by wire is in the public interest is not an easy one. Besides issues of fuel cost and feasibility under existing interconnection systems, see note 30 infra and accompanying text, power losses incurred in lengthy transmissions are substantial and might be unacceptable if more than temporary. J.App. 65 (conference statement by Mr. Blinn of NEPOOL) (“this does not appear to be a very efficient way of using national energy resources”). Additionally, persons living near coal-fired utilities may be subjected to an enduring degradation of their environment in order to provide electricity for individuals breathing unpolluted air hundreds or thousands of miles away. And study is just beginning on possible dangers from high voltage bulk transmission lines.

. As the Commission described it:
The electric power supply systems in the eastern, southern and midwestem regions of the United States normally'operate together in a synchronous manner to form a series of large interconnected electric power grids. Geographically, these interconnected systems extend from Maine to Florida and inland as far as Oklahoma, Nebraska and the Dakotas and include most power facilities in seven of the nine electric reliability councils. The far western states tend to operate as a separate series of power grids with weaker ties to the East. The interconnected systems in most of Texas operate as an electrically isolated power grid. Ownership of components of these systems is divided among investor owned utilities, agencies of the Federal Government and various publicly owned utility organizations and cooperatively owned systems. System reliability is accomplished under this Commission’s administratively established adequacy and reliability program pursuant to Section 202(a) of the Federal Power Act, and Order series 383, the latest being Order No. 383-3, 49 FPC 700 (1972). This program is voluntary, but it is the policy of the Commission that all electric systems shall have the opportunity to participate in the adequacy and reliability matters consistent with their needs. See Order series 383.

We are not entirely pleased with the Commission’s discussion of the economic principles operable in this situation. Although we can perceive the path to its conclusion on allocable costs, and although its choice of route was not unreasonable, we can also see that the Commission stumbled down the trail it had chosen. Irrespective of the direction in which the Commission ultimately heads, it could travel a smoother road if it would lay out the competing principles of ratemaking, explain why it accepts particular theories and rejects others, and then elucidate how the principles adopted support the specific allocation of costs. Such an explication would not only aid our review but, we believe, would lead to better informed and better reasoned decisions by the agency itself.

The Commission’s Atlantic Seaboard rate formula for jurisdictional pipelines allocated 50% of fixed costs to the commodity component of a two-part — demand and commodity— rate design. Atlantic Seaboard Corp., 11 F.P.C. 43 (1952). Although this apportionment does not coincide with pure system-peak responsibility pricing it has garnered judicial approbation, State Corp. Comm’n v. FPC, 206 F.2d 690, 709-710 (8th Cir. 1953), cert. denied, 346 U.S. 922, 74 S.Ct. 307, 98 L.Ed. 416 (1954), and has been generally followed for many years. The Commission’s justification of the resulting rate relies on fairness and value-of-service considerations. See Atlantic Seaboard Corp., supra, 11 F.P.C. at 53-56; J. Bonbright, supra note 42, at 354 n.16. In a recent decision, we approved a further shift of fixed costs to the commodity component as a just and reasonable pragmatic judgment in light of gas shortages and unused pipeline capacity.

FPC, supra, 324 U.S. at 615, 65 S.Ct. at 845, 89 L.Ed. at 1229 (Jackson, J., concurring) (“I do not think it can beraccepted as a principle of public regulation that industrial gas may have a free ride because the pipe line and compressor have to operate anyway”); id. at 591, 65 S.Ct. at 834, 89 L.Ed. at 1217 (majority opinion) (“considerations of fairness, not mere mathematics, govern the allocation of costs”); FPC v. Texaco, Inc., supra note 7, 417 U.S. at 387, 94 S.Ct. at 2321, 41 L.Ed.2d at 150 (“[t]hat every rate of every natural gas company must be just and reasonable does not require that the cost of each company be ascertained and its rates fixed -with respect to its own costs”); Public Serv. Comm’n v. FPC, 170 U.S.App.D.C. 153, 156, 516 F.2d 746, 749 (1975) (implying that cost is not necessarily the only secure foundation for ratemaking).
The rates set in this proceeding apply to service performed during the 1973 oil embargo, and the schedules that would otherwise have been applicable were as high or higher. New England Power Pool Participants, Coal-byWire, supra note 10, 52 F.P.C. at 416 (Order of Aug. 26, 1974). The Commission indicated that post facto prescription of rates based solely on incremental costs would discourage voluntary efforts to solve future fuel crises:
[W]e accept the settlement rates and charges as a reasonable compromise between the opposing interests on rate design principles and policy and we accept them for filing . . . for the additional purpose of making Fuel Conservation Service fully effective on a voluntary basis. The rates and charges in the case of Section 202(c) Commission-directed ‘emergency’ energy transfers shall be governed by the principles set forth in our Regulations Section 32.62E.

. Id. at 417; New England Power Pool Participants, Coal-by-Wire, supra note 13, at 16 (Order of Sept. 26, 1975), J.App. 951. PJM’s major demand comes from the urban corridor on the eastern border of its system. Its base load is primarily handled by minemouth units located to the west. Units in the cities are used during peak periods to meet the increased demand. Thus major west-to-east transmission lines are heavily loaded at all times. Of course, not all systems share this characteristic, although they all received rates based in part on fixed costs. This points up a potential defect in the use of rulemaking instead of individual adjudications in setting rates. The Commission should be wary of serious over-generalizing through rulemaking, but no one has raised a protest in this proceeding. See FPC v. Texaco, Inc., supra note 7, quoted in note 44 supra.

. State agencies submitting comments argued that the primary duty of utilities is to serve in-state ratepayers and not to give a “free ride” to consumers outside the service area. E. g., Letter from Public Service Commission of Indiana (Jan. 31, 1974), at 1-2, J.App. 109-110.

. The Commission made clear that it was not implying “that such cost allocation methods would be appropriate in the future . . . .” New England Power Pool Participants, Coal-by-Wire, supra note 10, 52 F.P.C. at 412 (Order of Aug. 26, 1974).
. At the time of its initial order of August 26, 1974, the Commission initiated a proceeding to establish regulations to govern procedures and rates for emergencies declared under § 202(c). 39 Fed.Reg. 31654 (1974). In response to extensive comments by parties including Richmond and Representative Harrington, the Commission ruled that should it be forced to set rates for service provided in future emergencies it would predicate those for non-firm service either on incremental costs or on a share-the-savings theory. 39 Fed.Reg. 42903, 43910-43911 (1974), reconsideration denied, 40 Fed. Reg. 5142 (1975). A petition for review of that rulemaking proceeding in this court was dismissed by agreement of the parties.
. Richmond is not complaining of unjustifiable discrimination in I&M’s rates, an injury which the Commission would have a duty to rectify. Compare Towns of Alexandria v. FPC, 181 U.S.App.D.C. 83, 91, 555 F.2d 1020, 1028 (1977) discussing Federal Power Act § 205(b), 16 U.S.C. § 824d(b) (1970).

. Id. at 424-425. We see nothing erroneous in the Commission’s characterization of Richmond’s position at that stage — “that its broad questions on restructuring the industry must be resolved first.” Id. at 423.
. Application for Rehearing by Richmond Power & Light, supra note 33, at 10, J.App. 929.
. We are not faced with a claim that I&M’s failure to utilize its transmission capability fully or to purchase less expensive electricity for ' wheeling resulted in unnecessarily high jurisdictional rates. Compare Niagara Mohawk Power Corp. v. FPC, 538 F.2d 966, 971 (2d Cir. 1976). I&M had contemporaneous rate hearings pending, but Richmond refused to air its complaints in that proceeding.
