Opinion for the Court filed by Circuit Judge STEPHEN F. WILLIAMS.
A cogeneration plant produces not only electric power but also steam or other thermal energy that can be used for various industrial or commercial purposes. 16 U.S.C. § 796. To encourage this source of energy, the Public Utilities Regulatory Policies Act of 1978, 16 U.S.C. § 824a-3 (“PURPA”), imposed a requirement on electric power utilities to purchase power from any qualifying facility (“QF”) — a cogeneration plant that meets PURPA’s QF standards. See 18 CFR §§ 292.101(b)(1), 292.203(b). The utility must pay for the power at a rate no greater than its “avoided cost” — the cost it would incur to generate an equivalent amount of power itself. See 16 U.S.C.§ 824a-3(b); 18 CFR §§ 292.304(a), 292.101(b)(6). Although the phrase “avoided cost” has the ring of an economically sound price, it was suggested without contradiction at oral argument that it has not so proved.
Niagara, a producer and seller of electricity in upstate New York and subject to the PURPA mandate, suspected that some of the facilities from which it buys may not actually qualify for QF status, and to pursue the matter filed a request with the Department of Energy (“DOE”) in 1995 under the Freedom of Information Act (“FOIA”), seeking information collected by DOE on forms that these facilities are required to file with DOE’s Energy Information Administration— Forms EIA-867. DOE disclosed some but withheld other information, invoking FOIA’s Exemption 4, 5 U.S.C. § 552(b)(4), which covers “trade secrets and commercial or financial information obtained from a person and privileged or confidential.” The information withheld relates particularly to quantities of fuel consumed and power generated, from which, given market prices for fuel, outsiders could go far to calculating a facility’s unit cost of power.
Niagara sued in district court to compel release of the withheld data. Independent Power Producers of New York, Inc., a trade group, and Sithe Energy Inc. (“QF Interve-nors” collectively) intervened in support of DOE. Both DOE and the QF Intervenors moved for summary judgment, supporting the motion with affidavits describing the QF industry. Niagara moved for discovery, and on the district court’s denial of its motion filed an opposition to the motion for summary judgment, attaching an affidavit depicting the industry in rather different terms. The district court granted summary judgment. It held that Niagara had failed to raise an issue of material fact against DOE’s position that the information was exempt because its release (1) would cause substantial competitive harm to the entities submitting the information (the QFs), and (2) would impair the agency’s ability to collect this information in the future. The court also rejected Niagara’s claim that no FOIA exemption could apply because the information was already publicly available.
The language of Exemption 4 protects from disclosure “commercial information” obtained from a. .non-government, source, so long as it is “privileged or confidential.” The only dispute here is over the last phrase. In
National Parks & Conservation Ass’n v. Morton,
In support of its claim that release would impair government interests, DOE offered two conelusory affidavits, claiming that disclosure would impair the EIA’s ability to collect such information in the future. See Walton Decl. 5739-43; Grutseh Decl., ¶10. The claim is inherently weak where, as here, the agency has secured the information under compulsion.
Critical Mass Energy Project v. NRC,
DOE insists that summary judgment is proper because Niagara did not controvert the assertions of impairment. But on a summary judgment motion, “[flacts not conclusively demonstrated, but essential to the movant’s claim, are not established merely by his opponent’s silence; rather, the movant must shoulder the burden of showing affirmatively the absence of any meaningful factual issue.” See
National Assoc. Of Gov’t Employees v. Campbell,
DOE fares no better in its effort to show that there is no genuine issue of material fact on the likelihood of substantial competitive harm. In
National Parks II,
we held that for the government to preclude disclosure based on a competitive injury claim, it must prove that the submitters “(1) actually face competition, and (2) substantial competitive injury would likely result from disclosure.”
Further, though implicitly accepting DOE’s and the QF Intervenors’ assumption that QFs’ competition with their steam hosts for the division of rents (quite apart from the long terms of the contracts) qualifies as “competition” for purposes of National Parks, Niagara contests the claim that they actually do so. See Cifaratta Decl. ¶ 14. (“[T]he arrangements between QFs and their steam hosts typically are not determined by ordinary market-based concerns ... QFs often provide steam to their hosts at very low rates, sometimes for free. Some QFs, in fact, subsidize their steam hosts in order to secure PURPA and PSL § 66-c benefits for themselves.”). While this struggle-free relation may seem unlikely, the contention directly contradicts the assertions on which the district court relied.
DOE’s other arguments relating to competitive injury are legally inadequate under the
National Parks
standard. For example, DOE argues that the QFs may face future or potential competition. But the test explicitly requires proof that the submitters face
actual
competition.
National Parks II,
As each legally sound theory offered by DOE is plagued by factual disputes, summary judgment was improper. On remand the district court will want to consider the Supreme Court’s observation that “categorical decisions may be appropriate and individual circumstances disregarded when a case fits into a genus in which the balance characteristically tips in one direction,”
U.S. Dep’t of Justice v. Reporters Committee for Freedom of the Press,
Niagara also claimed that Form EIA-867 information is already in the public domain — a proposition that if true would give, victory to Niagara independent of the matters discussed above. Niagara’s position here is a little odd: if the information is publicly available, one wonders, why is it burning up counsel fees to obtain it under FOIA? But the logic of FOIA compels the result: if identical information is truly public, then enforcement of an exemption cannot fulfill its purposes. See
Davis v. U.S. Dep’t of Justice,
Before this court, both DOE and the QF Intervenors claim that the information on Form EIA-867 is narrower in scope than that submitted on Form 556. But that claim is at odds with their position before the *20 district court. At argument on. the summary-judgment motion, counsel for the QF Inter-venors conceded that the information provided by QFs upon initial certification was “substantially identical to that found in form 867 and that information is public.” And DOE counsel supported this observation with equally emphatic language: “[The information] may be absolutely totally identical, but it’s projected. It’s not actual, and that’s the big difference.” Although obviously there is a world of difference between projected and actual data, -these positions either assert or assume that the information on the two forms is identical in scope.
The district court accepted DOE’s argument that while the certification information on Form 556 was only projected, the operational and performance information on Form EIA-867 was drawn from actual experience. Niagara did not dispute this, but countered by arguing that FERC regulations require QFs to make corrective filings once there are material changes in a QF’s operations. See 18 U.S.C. § 292.207(d)(1). But as the district court observed, such new information is required only when there are material changes in facts and representations included in the initial self-certification filing. Since these corrective filings are not necessarily made on an ongoing and continuous basis, Niagara seems to have initially failed to carry its burden.
But that is not the end of the story. After the district court’s holding in this case, the New York Public Service Commission rendered a decision authorizing electric utilities in New York to monitor the compliance standards set out in PURPA. See
Re Motion to Establish Programs for Monitoring Qualifying Facility Status,
Nos. 96-E-0775, 95-E-0264,
In response to the specific question why in light of this availability Niagara is still trying to obtain the Form EIA-867 information, Niagara responds that the Public Service Commission decision required information only from 1994 onwards, and that it wants to relieve itself (and in the end presumably its customers) from the costs of erroneous PURPA applications from earlier years. In fact, the time disparity is
worse
than that argument suggests, because the Federal Energy Regulatory Commission, though rejecting a claim by New York independent power producers that the New York decision was preempted by PURPA, denied it any effect as to data before the New York independents were on notice of the requirement,
1
on the ground that such a mandate would impose an undue burden on the producers. See
Independent Power Producers of New York, Inc.,
Before us DOE and the QF Intervenors try to undercut the relevance of the New York decision by arguing that the scope of information on Form EIA-867 is materially broader than that on Form 556. ■ But that was the scope claim that they effectively disavowed in district court; to allow them to raise it now for the first time on appeal would be grossly unfair to Niagara.
But Niagara is still by no means home free on this issue. For the period of most concern to Niagara, i.e., before the effective date of the Public Service Commission decision as modified by FERC, the New York mandate obviously fails to put the data into the public domain. But even as to those earlier data Niagara may have an argument on remand. 2 Even if the district court finds that the QFs are in competition that could be adversely *21 affected by disclosure of the earlier data if it alone were disclosed, those data may turn out to add so little to what is covered by the New York decision that its public disclosure will cause no additional competitive harm..
The district court’s order granting DOE’s motion for summary judgment is vacated and remanded.
So ordered.
Notes
. It is uncertain from FERC's decision, Independent Power Producers of New York, Inc., 80 FERC V 61,125 at 61,399 (1997), whether it regarded the QFs as being on notice from August 30, 1996, when the New York Commission made its initial declaratory ruling and order instituting the QF monitoring program, or from January 13, 1995, when FERC issued order No. 575, 60 Fed.Reg. 4831 (1995), which established FERC Form 556 and its data requirements, which were in turn picked up by the New York Public Service Commission.
. Since the New York decision issued after the judgment in this case, the district court never had an opportunity to consider it in evaluating Niagara's claims. Now it will.
