676 F.2d 763 | D.C. Cir. | 1982
Opinion for the Court filed by Circuit Judge WALD.
Petitioner, Consolidated Edison (“Con Ed”) challenges the Federal Energy Regulatory Commission’s (“FERC” or “Commission”) approval of an end use curtailment plan for natural gas that does not require customers who undergo below average curtailment to compensate those who are curtailed more than the average customer.
I. BACKGROUND
A. History of Curtailment Plans
Following natural gas shortages on a number of pipelines in 1970, the Commission
Two years after it first solicited curtailment plans, the Commission issued a policy statement stating its preference for end use curtailment plans. Order No. 467,49 F.P.C. 85 (1973). As modified by a subsequent order,
(1) Residential, small commercial (less than 50 Mcf on a peak day).
(2) Large commercial requirements (50 Mcf or more on a peak day), firm industrial requirements for plant protection, feedstock and process needs, and pipeline customer storage injection requirements.
(3) All industrial requirements not specified in (2), (4), (5), (6), (7), (8), or (9).
(4) Firm industrial requirements for boiler fuel use at less than 3,000 Mcf per day, but more than 1,500 Mcf per day, where alternate fuel capabilities can meet such requirements.
(5) Firm industrial requirements for large volume (3,000 Mcf or more per day) boiler fuel use where alternate fuel capabilities can meet such requirements.
(6) Interruptible requirements of more than 300 Mcf per day, but less than 1,500 Mcf per day, where alternate fuel capabilities can meet such requirements.
(7) Interruptible requirements of intermediate volumes (from 1,500 Mcf per day through 3,000 Mcf per day), where alternate fuel capabilities can meet such requirements.
(8) Interruptible requirements of more than 3,000 Mcf per day, but less than 10,000 Mcf per day, where alternate fuel capabilities can meet such requirements.
(9) Interruptible requirements of more than 10,000 Mcf per day where alternate fuel capabilities can meet such requirements.
Aside from the established physical fact that combustion of natural gas for raising steam in boilers and its subsequent conversion into electricity or mechanical energy results in a loss of roughly two-thirds of the heating value of the gas used — which we regard as unacceptably inefficient in time of shortage — we note also that those who use gas as boiler fuel generally can substitute other fuels more readily and at lower overall cost than other gas users; additionally, pollution control is more practical because of the large size of individual installations. Other fuels generally can be phsyically [sic] substituted in large boiler fuel applications with less inconvenience and less possible adverse consequences than in other industrial applications, such as direct fired uses, and other uses demanding precise temperature control, flame characteristics, instantaneous response and atmosphere quality.
Id. In addition to these efficiency concerns, the Commission found that its priority scheme would best protect “residential and small volume consumers who cannot be safely curtailed on a daily basis.” See 49 F.P.C. at 86.
End use plans were not without their critics. In a petition to this court, pipeline customers receiving below average percentages of their contracts argued that end use plans illegally reallocated natural gas among pipeline customers and were thus in violation of section 7(a) of the Natural Gas Act, 15 U.S.C. § 717f(a). We rejected this argument, ruling that section 7(a) only prohibits the Commission from ordering sales to new customers when to do so would impair service to existing customers. Since curtailment plans govern pipeline sales during retractions of service, rather than expansions of service, we held that section 7(a) is inapplicable to curtailment plans. See American Smelting & Refining Co. v. FPC, 494 F.2d 925, 936 (D.C.Cir.), cert. denied, 419 U.S. 882, 95 S.Ct. 148, 42 L.Ed.2d 122 (1974). Subsequently, in North Carolina v. FERC, 584 F.2d 1003, 1011 (D.C.Cir.1978), we discussed at greater length the scope of the Commission’s curtailment authority, explaining that discriminatory treatment of distributors is only justified to the extent that a curtailment plan reasonably reflects the actual impact that plan will have on ultimate consumers. Thus, we suggested that an end use plan based on a fixed-base period must be justified in terms of its current effects on preferred end users.
The Commission originally opposed compensation plans on the ground that it lacked jurisdiction to order such payments.
The curtailment plan at issue in this case has been working its way through administrative and judicial proceedings since 1973. On May 31, 1973, Texas Eastern Transmission Company (“Texas Eastern”) submitted its permanent curtailment plan
In the proceedings before the Administrative Law Judge (“ALJ”) on remand, two of Texas Eastern’s customers submitted compensation plans. Elizabethtown Gas Co. suggested that customers should be compensated for the excess cost they incurred in purchasing supplemental gas supplies (e.g., intrastate gas or synthetic gas).
The ALJ rejected both these plans and the Commission affirmed. The Commission began its analysis by distinguishing between two types of compensation claimants — low priority end users making direct purchases from Texas Eastern and distribution companies which buy from Texas Eastern and sell natural gas to low priority end users. In discussing the first group, the Commission referred to its past practices in certifying natural gas transportation for low priority end users. Under section 7 of the Natural Gas Act, 15 U.S.C. § 717f, certificates of public convenience and necessity are issued when they are “necessary or desirable in the public interest.” The Commission explained that when supplies were adequate, service to large low priority users met this standard because it benefited the entire pipeline. The low priority end user received cheap fuel and costs to the rest of the pipeline’s customers were reduced as a result of the increased load factor.
With regard to the distribution companies, the Commission found that compensation would unduly reward those companies that had successfully played the “load factor game” in the past by providing service to low priority end users. A distribution company’s “load factor” reflects the ratio of average demand to peak demand. See P. Garfield & W. Lovejoy, Public Utility Economics 153 (1964). The higher the load factor, or the more demand is pushed from peak to off-peak periods, the lower the distributor’s unit costs. Thus, distributors typically sought to raise their load factor: some by providing off-peak service to low priority industrial customers; and others by building storage facilities to hold gas purchased during off-peak periods for resale in periods of peak demand. Not all distributors, however, were able to employ either method for increasing their load factor. These distributors, who generally served small towns in rural areas, simply paid higher prices for natural gas supplies.
The Commission recognized that a consequence of these different methods for increasing load factor is that some residential end users are more severely affected by an end use curtailment plan than others. The heaviest curtailment-related costs fall on customers of distribution companies that had relied on low-priority industrials to increase their load factor. Due to their above average curtailment, these distribution companies must either purchase above average amounts of expensive alternative fuels — which would lead to higher retail prices — or else they must discontinue service to some customers — which would lead to higher unit costs for the remaining customers. In contrast, distribution companies that had invested in storage facilities to increase their load factor or had not played the “load factor game,” receive proportionately more natural gas during curtailment because proportionately more of their retail customers are residential users. As a result, these latter distribution companies are under less pressure to increase their retail prices during periods of curtailment.
The Commission found that these disparate effects of curtailment fairly reflect the past load factor strategy of distributors. It reasoned that customers of distributors without industrial loads had paid increased prices in the past due to low load factor or the distributor’s costs of constructing and maintaining storage facilities. It concluded “[n]o one earlier suggested during times of plentiful supplies that the benefits obtained from service to industrials should be shared by one distributor with another distributor who did not have an industrial load; and we find no cause to now engage in the reverse process.”
The Commission also found that Texas Eastern’s demand charge credit adjustment would partially mitigate the impact of end use curtailment on residential customers whose distribution companies had previously maintained a high industrial load. “Demand charges” allocate the fixed costs of a pipeline among its distributor customers. See 1 A. Priest, Principles of Public Utility Regulation 337-38 (1969). Through Texas Eastern’s demand charge adjustment formula, the demand charge for distribution companies that undergo above average curtailment is credited to reflect capacity that is no longer being served.
Turning finally to the particular compensation schemes offered by Elizabethtown and Con Ed, the Commission found that neither scheme would equitably allocate the economic hardship of a natural gas shortage. The Commission first noted that both plans sought to reallocate costs so as to require high and low priority customers to share equally in the economic hardship attending natural gas shortages — an objective the Commission had earlier rejected in its policy discussion. But even assuming that compensation would be appropriate in some circumstances, the Commission found the two proposed schemes to be defective. Elizabethtown’s plan, which would compensate curtailed customers for their most expensive supplemental supplies, placed no cap on costs that could be charged to the pipeline. The Commission explained that this plan contained a potential for abuse since customers curtailed at above average rates would have little incentive
Unlike Elizabethtown’s plan, Con Ed’s compensation scheme would not skew incentives to minimize costs. Con Ed’s plan would employ an index of substitute fuel costs — the price of No. 6 residual fuel oil— to determine the excess cost incurred by those customers undergoing above average curtailment. Regardless of the costs they actually incurred, curtailed customers would receive compensation computed by multiplying the difference between the price of fuel oil and the regulated natural gas price times the difference between the company’s pro-rata share of natural gas and the amount it actually receives.
In its petition for rehearing, Con Ed objected to the Commission’s reliance on the low priority historically placed on boiler fuel use as a rationale for denying compensation. It argued that “[ujntil the onset of deep curtailments in the early 1970’s . . . virtually every denial of a boiler fuel sale was reversed in subsequent actions by the Commission.”
The Commission’s certificate decisions, thus, do not evidence that neutrality on end-use which would have to be present in order to support utilization of pro rata principles in fashioning appropriate curtailment plans; and a key premise of proponents of compensation cannot be justified. The Commission’s certificate decisions support the conclusions that there are more preferred and less preferred end uses for natural gas, relative to alternative fuels which are available for those uses, and that a hierarchy based on end-use may be appropriate where a key conclusion in the certificate process, the adequacy of natural gas supplies, is no longer present. Because we are unable to find an indifference in the Commission’s certificate decisions to end-use, there is no need to balance end-use curtailment plans with compensation features predicated on pro rata concepts.25
In its petition for review, Con Ed argues that the Commission erred (1) by not basing its compensation decision on the premise that the economic hardship of curtailment should be allocated according to private contractual arrangements; (2) by relying on the NGPA; (3) by finding that demand and commodity charge adjustments are adequate compensation; (4) by finding that past benefits accorded to customers curtailed at above average rates offset any need for compensation;
II. ANALYSIS
A. Statutory Limitations on the Commission’s Curtailment Authority
Although Con Ed and the Commission often refer to the compensation issue as a matter of fairness,
The Supreme Court first ruled on the Commission’s curtailment powers in FPC v. Louisiana Power & Light Co., 406 U.S. 621, 92 S.Ct. 1827, 32 L.Ed.2d 369 (1972). Louisiana Power & Light had argued that the Commission’s authority over direct sale customers is limited to approving or denying certificates of public convenience. Rejecting this view, the Court ruled that the Natural Gas Act provides the Commission with independent grants of jurisdiction over “(1) the transportation of natural gas in interstate commerce; (2) its sale in interstate commerce for resale; and (3) natural gas companies engaged in such transportation.” Id. at 636, 92 S.Ct. at 1836 (quoting Panhandle Eastern Pipe Line Co. v. Public Service Commission, 332 U.S. 507, 516, 68 S.Ct. 190, 194, 92 L.Ed. 128 (1947)). The Court noted that only the second grant of jurisdiction is restricted in scope to sales for resale. Characterizing curtailment regulations as matters regarding transportation rather than rate-setting, the Court ruled that such regulations are within the Commission’s power. Turning to the scope of that power, the Court first stated that the Commission, as an “[agency] created to protect the public interest, must be free, ‘within the ambit of [its] statutory authority to
No natural-gas company shall, with respect to any transportation or sale of natural gas subject to the jurisdiction of the Commission, (1) make or grant any undue preference or advantage to any person or subject any person to any undue prejudice or disadvantage, or (2) maintain any unreasonable difference in rates, charges, service, facilities, or in any other respect, either as between localities or as between classes of service.
Con Ed urges there that Texas Eastern’s curtailment plan creates “undue” or “unreasonable” discrimination because it fails to treat all customers’ contracts equally.
We do not view section 4’s mandate against “undue” preferences and “unreasonable” discrimination so strictly. The mere fact that Texas Eastern’s plan treats different kinds of contracts for natural gas differently does not mean that the plan is “undu[lyj” preferential or “unreasonably]” discriminatory as to those whose contract rights are affected. As the Commission explained in its original policy statement endorsing end use curtailment plans, contractual commitments do not necessarily serve the public interest in efficiently allocating scarce natural gas supplies. Through its approval of end use curtailment plans, the Commission has sought to protect the public interest by funneling natural gas supplies to those who face the highest conversion costs or for whom curtailment represents the greatest hardship. Insofar as Texas Eastern’s curtailment plan properly serves that goal — an issue which has already been settled in a previous proceeding
Con Ed also cites as error the Commission’s rationale that its prior pattern of certification decisions as to the public interest served by low priority uses of natural gas supports its present policy of rarely, if ever, ordering compensation payments. Con Ed argues that while the Commission has designated certain uses of natural gas, such as boiler fuels, as “inferior uses” it has in fact routinely certified sales to boiler fuel facilities. Since end use was not, in fact, a controlling factor in these certification proceedings, it concludes, end use factors cannot now justify a policy of refusing compensation for contract holders who have been curtailed above the average for the pipeline system. Petitioner’s Brief at 26.
We think that Con Ed’s view of the significance of the Commission’s boiler fuel certification decisions misses the mark. Although there is no doubt that the Commission certified boiler fuel usage during times of more plentiful supplies, the reasoning of its certification decisions has considerable bearing on its refusal to require that curtailment plans include a compensation feature. If, indeed, low priority end uses were only certified when doing so would benefit higher priority users, compensation to the low priority users at the expense of the high priority customers would run against prior Commission policy by substituting “definite burdens . . . for the indirect benefit previously conveyed.” Respondent’s Brief at 40.
A review of past Commission decisions demonstrates that the Commission has historically distinguished among different end uses of natural gas, requiring lower priority end users to justify their receipt of natural gas by demonstrating offsetting public advantages.
The Commission’s past (and present)
C. Implications of the 1978 Energy-Acts
Con Ed also disputes the Commission’s reliance on the NGPA and the Fuel Use Act to support its denial of compensation. Con Ed argues that neither Act directly addressed the compensation issue, although the propriety of compensation provisions was at the time being vigorously contested before the Commission and in the courts. We agree with Con Ed that these Acts do not point clearly in favor or against compensation plans. We do believe, however, that these Acts generally support our conclusion that the decision whether to employ end use or pro rata concepts in allocating the economic hardship of a natural gas shortage is a matter of policy for the Commission.
The Commission sought support for its rejection of compensation schemes in the conference report accompanying the NGPA. It noted that in establishing agricultural uses of natural gas as a matter of relatively high priority
We find this argument unpersuasive. Although compensation payments would no doubt lead to increased prices for food, and
The Commission also seeks support for its refusal to require compensation in the Fuel Use Act’s provisions prohibiting power-plants from using natural gas as a primary energy source after 1990. See 42 U.S.C. § 8341 (Supp. IV 1980). The Commission found that while this prohibition is far more restrictive than a temporary curtailment, it limits “compensation” to cases in which the powerplant finds a purchaser for its right to receive natural gas, and even in such a case, limits the supply rights of the purchaser of the contract to those of its original holder. See 42 U.S.C. § 8441 (Supp. IV 1980). Thus, if the powerplant would have no right to receive natural gas during periods of curtailment, the purchaser of its contract would also have no right to receive natural gas during such periods. These provisions, however, do not seem to us to lend particularly weighty support to the Commission’s rejection of Con Ed’s compensation proposal. The Fuel Use Act says nothing about whether curtailed customers should receive compensation payments; it only says that those who do not have a right to the physical receipt of natural gas during periods of curtailment cannot create such a right in those to whom they sell their natural gas contracts. See 42 U.S.C. § 8441(g) (Supp. IV 1980). If we were to rule that curtailed customers had a right to receive compensation payments during periods of curtailment, they could no doubt pass that right along to those who purchase their natural gas contracts.
Thus, we cannot agree with the Commission that the Energy Acts provide direct support for its rejection of compensation schemes. We do find, however, that they support our conclusion that the provision of compensation is a matter of policy properly left to the Commission. Read as a whole, the Energy Acts indicate Congressional concern both with protecting high priority end users from cost increases,
D. Adequacy of Demand and Commodity Charge Adjustments
In its opinion rejecting Con Ed’s compensation scheme, the Commission relied in part on provisions in Texas Eastern’s curtailment plan that adjust the commodity and demand charges paid by distributor customers curtailed more than the system average. Con Ed argues that these adjustments are inadequate compensation since they do not account for fixed costs on the distributor’s system (which must be paid by the remaining customers) or the cost of alternative fuel. See Petitioner’s Brief at 31. Con Ed suggests that the distributor customer would rather receive the natural gas than such inadequate compensation.
We do not doubt that Con Ed has properly concluded that distributors would prefer receiving natural gas to receiving demand and commodity adjustments. As the Commission points out in its brief, this preference results from the difference between the regulated price of natural gas and its real value, as measured by the price of alternative fuels. While those who receive natural gas only pay the regulated price, curtailed customers such as Con Ed, are left to purchase alternative fuels in markets that are often unregulated. Since commodity and demand charge adjustments only compensate distributors at the regulated cost-based natural gas price, they may not provide sufficient funds to cover the cost of alternative fuels.
We disagree, however, with Con Ed’s suggestion that the Commission erred by finding Texas Eastern’s demand and commodity charge adjustments to be adequate “compensation.” The Commission’s consideration of these adjustments followed its policy conclusion that Con Ed was not entitled to full compensation for its replacement fuel costs. Having reached this policy conclusion, the Commission properly examined Texas Eastern’s tariff to ensure that Con Ed would not end up paying for natural gas that it would not receive.
E. Deficiencies in Con Ed’s Proposed Compensation Plan
Con Ed also contends that the Commission erroneously placed on Con Ed the burden of developing a workable compensation
If a compensation plan were necessary to render a curtailment plan just and reasonable, we do not doubt that the burden of establishing a workable plan would rest on the proponent of the plan. But we have previously held that curtailment plans may be reasonable without any compensation features. See City of Willcox v. FPC, 567 F.2d at 420; id. at 424-25 (Bazelon, J., concurring). Since compensation schemes are not a required part of a curtailment plan, we conclude that the Commission did not err by placing the burden of developing a workable plan on those-parties requesting compensation.
Turning to the specific plan proposed by Con Ed, we find that the Commission did not err by concluding that the plan was seriously defective. First, the plan was based on the unrealistic and rigid assumption that curtailed customers would convert to oil. Should oil prices rise by more than alternative fuels, Con Ed’s plan would provide windfalls to curtailed customers at the expense of higher priority end users. Indeed, the Commission found that Con Ed’s own experience in adjusting to natural gas curtailment indicated that this hypothesis was grounded in experience. Second, Con Ed’s plan provided no assurance that compensation paid to distributors would be directed to curtailed end users. Absent such assurance, the plan allowed for payments from one group of residential customers to another which would be disproportionate to any economic burdens associated with end use curtailment.
F. Constitutional Claim
In its petition for review, Con Ed argues for the first time that its contractual right to purchase natural gas from Texas Eastern is “property” within the meaning of the fifth amendment and that this property was “taken away” when the Commission approved a curtailment plan that allocates Con Ed’s natural gas entitlements to other pipeline customers.
Although we seriously doubt that Con Ed’s claim has any merit
No objection to the order of the Commission shall be considered by the court [of appeals on petition for review] unless such objection shall have been urged before the Commission in the application for rehearing unless there is reasonable ground for failure to do so.
49 U.S.C. § 717r(b) (emphasis added). As interpreted by the Court, this statute serves not only to bar petitioners from raising novel issues, but also serves to bar courts of appeals from raising, sua sponte, objections that were not pressed before the Commission. See FPC v. Colorado Interstate Gas Co., 348 U.S. 492, 498-99, 75 S.Ct. 467, 471, 99 L.Ed. 583 (1955).
Con Ed argues that section 19(b) should not bar its constitutional argument because the taking question is intertwined with its statutory argument, and, indeed, the Commission took note of this connection in its opinion.
We disagree. The Commission’s opinion specifically noted that Con Ed had not couched its compensation argument in constitutional terms, but had relied “solely on the Natural Gas Act.”
In conclusion, we find that the Commission has adequately justified its refusal to require Texas Eastern to provide compensation measured by replacement costs to customers curtailed more than the system average. We therefore affirm the Commission’s rulings in this case.

. Temporary curtailments of residential users are considered unsafe because of the danger that low gas pressure will extinguish pilot lights, thereby allowing gas to seep out into homes and create a danger of explosion. See M. Willrich, Administration of Energy Shortages 31-32 (1976). Temporary curtailments are also dangerous to public health and safety because it is not feasible for residential users to switch temporarily to other fuels and so they must endure cold homes during periods of curtailment. See Opinion No. 92 at 4, J.A. 76.
. The Commission takes the position that North Carolina does not control curtailment plans formulated under the Natural Gas Policy
.In these earlier proceedings, the Commission took the position that compensation payments are “rates” and that requiring only some pipeline customers to pay such “rates” would be discriminatory. The fifth circuit rejected this view in Mississippi Pub. Serv. Comm’n. v. FPC, 522 F.2d 1345, 1350 (5th Cir. 1975), cert. denied, 429 U.S. 870, 97 S.Ct. 181, 50 L.Ed.2d 149 (1976). The fifth circuit suggested that rather than being ordinary rates, compensation payments are surcharges “imposed in the context of a curtailment plan to insure that the burdens of curtailment are spread evenly and equitably among those affected by such plans. ... [Compensation payments are more analogous to the penalty payments included by the Commission in various curtailment pláns to deal with the problem of overtakes.” Id. (footnote omitted).
This circuit has not sought to classify compensation payments as either “rates” or “surcharges.” See Transcontinental Gas Pipe Line Corp. V. FPC, 562 F.2d 664, 668 n.5 (D.C.Cir.1976), cert. denied, 436 U.S. 930, 98 S.Ct. 2830, 56 L.Ed.2d 775 (1978) (“ ‘Surcharges’ and ‘penalty payments’ ... suggest limited application of a pricing mechanism for a short duration to achieve a clearly defined purpose; higher prices for gas sold as emergency relief or improperly taken in excess of curtailment, may not necessarily be analogous to varying permanent prices for gas allocated by the curtailment plan itself.”). Instead, this circuit has characterized the Commission’s authority to order compensation as within its “latitude to make ‘pragmatic adjustments which may be called for by particular circumstances.’ ” See Elizabethtown Gas Co. v. FERC, 575 F.2d 885, 888 (D.C.Cir.1978) (“Elizabethtown I”).

. We touched on this question briefly in City of Willcox v. FPC, 567 F.2d 394 (D.C.Cir.1977). In Willcox, we bypassed the jurisdictional question by finding that a compensation plan would not be appropriate under the facts of that case. In particular, we noted that no specific compensation scheme had been presented to the Commission for its consideration. In dicta, we also stated that compensation payments “would be inconsistent with the entire purpose behind [end use curtailment].” 567 F.2d at 420.
Willcox’s dicta does not withstand closer scrutiny. Indeed, there is nothing inherently inconsistent about allocating natural gas to those who are most in need of it while requiring the beneficiaries of such a plan to compensate those who must purchase more expensive alternative supplies. Cf. 15 U.S.C. § 3363(g) (requiring compensation, measured by replacement fuel costs, when gas is reallocated under the President’s emergency powers). Our conclusion that compensation would not be inconsistent with end use curtailment, however, does not mean that the Commission must require compensation payments. As we explain, infra, the absence of compensation payments does not by itself render an end use curtailment plan unduly preferential or discriminatory. Thus, so long as the Commission has not arbitrarily rejected the compensation schemes proposed here, we must uphold its approval of Texas Eastern’s curtailment plan.

.This objection is based on a misreading of the Commission’s opinion and is therefore easily disposed of. Con Ed argues that the entire pipeline benefited from industrial loads in times of sufficient natural gas supplies and that such sales were in the public interest. Thus, it concludes, it is inequitable to place on the distributor who supplied such pipeline-wide benefits the burden of paying for higher cost alternative fuels. But as the Commission explained, the benefits to the distributor who increased his industrial load were disproportionate to the benefits to the pipeline. See id. at 14-15; J.A. 235-36. It was this disproportionate benefit that led the Commission to conclude that “no legal, equitable, or policy reason supports un
. Con Ed argues that the Commission’s history of consistently rejecting compensation plans demonstrates that it was predisposed against requiring compensation here, and that it has shown that it will essentially reject compensation under all circumstances. As neither of these arguments has any merit, there is no need to discuss them extensively. The Commission’s prior erroneous belief that it lacked the power to order compensation surely does not bear on its judgment that compensation payments are unwarranted in this case or on its future actions in different circumstances. Since there is no doubt the Commission carefully considered Con Ed’s arguments, the only issue before us is whether its grounds for rejecting those arguments are adequate.
. This characterization of the compensation issue stems from dicta in Elizabethtown I:
The question of whether, and how, to provide compensation may well turn on the fairness of balancing the benefit accorded á high-priority purchaser with a charge that offsets, at least in part, the added expense imposed by a curtailment plan upon a lower-priority purchaser.
575 F.2d at 889 (footnote omitted). We proceeded, however, to note that “[t]he issue on fairness is an issue of policy for the Commission. Our function is only to consider the issue of law whether the Commission has the legal authority to implement that policy of fairness.” Id. n.3.
Now, of course, we are no longer asked to speculate about what considerations the Commission may take into account in deciding whether to employ a compensation plan. Instead, we are only concerned with whether the Commission has abused its discretion by approving an end use curtailment plan that lacks compensation provisions.
. In its brief, Con Ed argued that the Commission’s failure to employ pro rata considerations was arbitrary and capricious. See Petitioner’s Brief at 24-29. In its reply brief, Con Ed re-framed this argument in terms of undue discrimination. See Reply Brief at 11. The Commission viewed these two issues as one and the same. See Opinion No. 92 at 6; J.A. 78.
. See Elizabethtown II, 636 F.2d at 1333; note 6 supra.
.We do not read this court’s opinion in North Carolina v. FERC, 584 F.2d 1003 (D.C.Cir.1978) to require a different result. In North Carolina the Commission had rejected a compensation scheme because it assumed that it lacked jurisdiction to order compensation. Remanding that case to the Commission, we noted that “[bjecause of the lasting discrimination inherent in an end use permanent curtailment plan, the level of compensation accorded customers enduring heavier-than-average curtailment is a factor bearing on the reasonableness of the plan . . . .” See id. at 1017. The discrimina
An end use plan might be unduly discriminatory if it failed to treat those in similar circumstances similarly. In this case, however, there is no indication that Con Ed’s residential users are disadvantaged in comparison with other residential users except to the extent that they had previously received load factor advantages. See p. 769 supra. Indeed the Commission’s comparison of Con Ed’s and Brooklyn Union’s rates indicates that the evidence is to the contrary. See Opinion No. 92 at 50-51; J.A. 122-23. In any event, Con Ed has not made such a showing of discrimination in this case.
. We recognize that this court has previously held that the pattern of the Commission’s past certification decisions is not sufficiently clear to support a specific scheme of end use priorities. See American Smelting & Refining Co. v. FPC, 494 F.2d 925, 944-46 (D.C.Cir.), cert. denied, 419 U.S. 882, 95 S.Ct. 148, 42 L.Ed.2d 122 (1974) (discussing the Commission’s characterization of boiler fuel as an inferior use). Thus, in approving end use curtailment plans, we have required a more searching factual inquiry into the propriety of the Commission’s priority scheme. See id.; City of Willcox v. FPC, 567 F.2d 394, 405-07 (D.C.Cir.1977), cert. denied, 434 U.S. 1012, 98 S.Ct. 724, 54 L.Ed.2d 755 (1978) (affirming the Commission’s designation of boiler fuel as an inferior use on the basis of record evidence). Nevertheless, the Commission’s past policy of requiring less-preferred users of natural gas to justify their receipt of gas in terms of benefits to the system has some bearing on the issues in this case. We read the Commission’s opinion as relying on this latter policy, rather than any specific end use designation.
. See, e.g., Florida Power & Light Co. v. FERC, 598 F.2d 370, 380 (5th Cir. 1979).
. Whether the Commission might have determined that its policies in favor of contractual stability, see Permian Basin Area Rate Cases, 390 U.S. 747, 822, 88 S.Ct. 1344, 1388, 20 L.Ed.2d 312 (1968), outweigh policies in favor of protecting high priority end users from economic burdens occasioned by the presence of lower priority end users is not the issue before us. Recognizing that the balance to be struck between these conflicting policies is generally a matter within the Commission’s discretion, we decide only that the Commission’s chosen balance does not violate the substantive policies of the Natural Gas Act.
. The five energy acts of 1978 were: the Public Utility Regulatory Policies Act, Pub.L.No. 95-617, 92 Stat. 3117 (1978); National Energy Conservation Policy Act, Pub.L.No. 95-619, 92 Stat. 3206 (1978); Natural Gas Policy Act, Pub.L.No. 95-621, 92 Stat. 3350 (1978); Energy Tax Act, Pub.L.No. 95-618, 92 Stat. 3174 (1978); Powerplant and Industrial Fuel Use Act, Pub.L.No. 95-620, 92 Stat. 3289 (1978).
.Section 401(f) of the NGPA, 15 U.S.C. § 3391(f) (Supp. IV 1980), defines high priority users as:
(2) HIGH-PRIORITY USER. — The term “high-priority user” means any person who—
(A) uses natural gas in a residence;
(B) uses natural gas in a commercial establishment in amounts of less than 50 Mcf on a peak day;
(C) uses natural gas in any school, hospital, or similar institution; or
(D) uses natural gas in any other use the curtailment of which the Secretary of Energy determines would endanger life, health, or maintenance of physical property.
Under the NGPA, natural gas for essential agricultural uses may not be curtailed unless the only alternative is to curtail a “high-priority user,” and curtailment will not lead to natural gas deliveries for agricultural use below specified use requirements. See 15 U.S.C. § 3391 (Supp. IV 1980).
. Under the NGPA’s provisions for incremental pricing, for example, high priority end users are shielded from price increases caused by purchases of new natural gas. See 15 U.S.C. § 3343 (Supp. IV 1980). These provisions also protect some low priority end users from the effects of high new natural gas prices. See 15 U.S.C. § 3346(c) (Supp. IV 1980).
. Under 15 U.S.C. § 3363(g) (Supp. IV 1980) those from whom natural gas is taken under the President’s emergency reallocation authori
. See note 38 supra and pp. 775-776 supra.
. Although we find that the Commission erred in concluding that the Energy Act support its rejection of compensation schemes, there is no need to remand this case to the Commission. In its opinion, the Commission stated that each of its grounds for rejecting compensation supported its decision. See Opinion No. 92 at 1; J.A. 83. Thus even if one ground proves to be too weak, the Commission’s policy may still stand on its other rationales.
. Unless state commissions require distributors to forward compensation payments to curtailed low priority end users, those payments would lead to reduced rates for residential customers. These residential customers, however, are not the parties who will suffer the costs associated with purchasing replacement supplies. The only costs they will have suffered are their increased shares of the distributor’s fixed costs. There is no reason to suppose that these increased shares of the distributor’s fixed costs bear any relation to the compensation payments provided under Con Ed’s plan.
. Con Ed’s taking claim rests on the difference between its contractual entitlements under general principles of contract law and its entitlements under Texas Eastern’s Commission-approved curtailment plan. Con Ed recognizes that, in times of shortage, pipelines cannot fulfill all of their contractual commitments. But it argues that general principles of contract law would require a fair and equitable distribution of natural gas during a shortage. See, e.g., Terry v. Atlantic Richfield Co., 72. Cal.App.3d 962, 968, 140 Cal.Rptr. 510, 513 (1977). It concludes that when the government departs from a pro-rata scheme for allocating shortages, the parties’ underlying contractual rights require that those receiving less than their fair share of natural gas be compensated.
.There are a number of obvious weaknesses to Con Ed’s taking argument. First, it is far from clear that private contractual arrangements are “property” within the meaning of the fifth amendment. Although the Court has stated in broad dicta that “valid contracts are property whether the obligor be a private individual, a municipality, a state or the United States,” see Lynch v. United States, 292 U.S. 571, 579, 54 S.Ct. 840, 843, 78 L.Ed. 1434 (1934); see also L. Tribe, American Constitu
. See Opinion No. 92 at 5 n.4; J.A. 77.
. Id. at 5-6; J.A. 77-78.
. Con Ed’s failure to press its constitutional objection in its petition for rehearing is especially significant since the Commission had already done the job of explaining that the fairness issue could be raised in both statutory and constitutional terms. A different result might be appropriate when statutory and constitutional issues are closely intertwined and neither the parties before the Commission, nor the Commission itself, treats them as separable issues. Cf. NLRB v. Blake Construction Co., 663 F.2d 272, 283-84 (D.C.Cir.1980) (objections regarding scope of complaint, substantiality of evidence, and ALJ’s conduct of proceeding adequate to preserve due process objections).
