Opinion for the Court filed by Circuit Judge BROWN.
The Federal Energy Regulatory Commission certified intervenor Ormesa LLC (Ormesa) as a qualifying geothermal small power production facility, entitling it to certain privileges pursuant to Section 210 of the Public Utility Regulatory Policies Act of 1978 (PURPA), 16 U.S.C. § 824a-3. In particular, the certification permitted Ormesa to compel traditional utilities to purchase Ormesa’s net power output. Southern California Edison Co. (Edison), a utility that has a power purchase agreement with Ormesa, petitions for review, arguing the Commission acted arbitrarily and capriciously by permitting Ormesa to sell capacity in excess of its net output and by distinguishing between brine extraction and brine reinjection in calculating the net output in the first place. Finding no basis for upsetting the Commission’s order, we deny the petition for review.
I
Congress enacted Section 210 of PURPA, 16 U.S.C. § 824a-3, to encourage the development of cogeneration and small power production facilities.
FERC v. Mississippi
To counter traditional electric utilities’ reluctance to deal with these nontraditional facilities, the PURPA charges the Commission with implementing mandatory purchase and sell obligations, requiring electric utilities to purchase electric power from, and sell power to, qualifying cogen-eration and small power production facilities (collectively, “qualifying facilities” or “QFs”).
See id.
§ 824a-3(a)(l)-(2);
FERC v. Mississippi,
Hewing to the PURPA’s mandate, the Commission enacted regulations requiring a utility to purchase “any energy and capacity which is made available from a[QF],” 18 C.F.R. § 292.303(a), and to sell “any energy and capacity requested by the [QF],”
id.
§ 292.303(b). While the utility must sell electricity to a QF at regulated tariff rates, the utility must buy electricity from the QF at a rate equal to the utility’s full “avoided cost.”
See Conn. Valley Elec.,
The Commission certifies the amount of power (“qualifying output” or “qualifying power”) that a QF can require a utility to purchase. The Commission determines a QF’s quаlifying output by looking to the QF’s net output rather than its gross output.
Penntech Papers, Inc.,
48 F.E.R.C. ¶ 61,120, at 61,423,
By only certifying a QF’s net output (rather than gross output) as qualifying output, the Commission prevents a QF from purchasing power for its auxiliary load from one utility at retail rates and then attempting to sell its entire gross output to another utility at avoided cost rates. Penntech Papers, 48 F.E.R.C. at 61,423. This accords with the purposes behind the PURPA, as the Commission thus cеrtifies the amount of output that the QF actually contributes to the system — the amount that will displace electricity produced by traditional means. Id. The Commission has cautioned that “[all-lowing [a QF] to sell the gross output at one utility’s avoided cost rates while the [QF] purchases the auxiliary power at another utility’s retail rates may very well result in an economic distortion.” Id.
Until recently, a QF had to be “owned by a persоn not primarily engaged in the generation or sale of electric power (other than electric power solely from cogeneration facilities or small power production facilities).” 16 U.S.C. § 796(17)(C)(ii) (2000) (qualifying small power production facility);

§ 796(18)(B)(ii) (qualifying co-generation facility);

This changed, however, with the Energy Policy Act of 2005 (the Act), Pub.L. No. 109-58, § 1253(b), 119 Stat. 594, 970 (amending 16 U.S.C. § 796(17)(C) & (18)(B)), which eliminated the statutory ownership limitation. 3 Consequently, the Commission removed the corresponding regulation, noting that “[rjemoval of the ownership prohibition removes the bar to a QF selling non-QF electric energy while retaining QF status.” Revised Regulations Governing Small Power Production and Cogeneration Facilities, 71 Fed.Reg. 7852, 7864 (Feb. 15, 2006) (deleting 18 C.F.R. § 292.206).

Ormesa is a geothermal small power production facility located in Imperial County, California, with a gross capacity of 19.95 megawatts (MW). Ormesa was originally certified as a QF by the Commission in 1986.

Edison is an investor-owned electric utility that generates and purchases electric energy and resells it to consumers in Southern California. Edison purchases power from Ormesa under a power purchase agreement consistent with Commission regulations, see 18 C.F.R. § 292.101 et seq. The agreement requires Ormesa to maintain its QF status at all times.
On February 3, 2004, Ormesa filed an application for re-certification as a QF. Ormesa argued the auxiliary load consisted solely of the in-facility activities, such as
The Commission agreed in part with each party.

107 F.E.R.C. ¶ 61,043,
In a footnote, however-, the Commission granted Ormesa permission to sell an additional 1.35 MW of power in excess of its net output without imperiling its QF status, notwithstanding the ownership limitation. 7 Certification Order, 107 F.E.R.C. at 61,151 n.10. The Commission made this allowance insofar as “the 1.35 MW will be purchased from another QF,” and pointed to Connecticut Valley, 82 F.E.R.C. at 61,-418 & n.17, for the proрosition that “a sale in excess of net output would deprive a facility of its QF status unless the incremental sale consisted of power solely from cogeneration or small power production facilities.” Certification Order, 107 F.E.R.C. at 61,151 n.10.
Ormesa and Edison each unsuccessfully requested rehearing. See Ormesa LLC, 108 F.E.R.C. ¶ 61,299 (2004) {Rehearing Order). Edison now brings a timely petition for review.

We address Edison’s challenge to the Commission’s decision under the deferential arbitrary and capricious standard set forth in the Administrative Procedure Act. 5 U.S.C. § 706(2)(A);
Exxon Mobil Corp. v. FERC,
A
Edison first challenges the Commission’s application of the ownership limitation — specifically, the decision to grant Ormesa permission to sell more than its net output while maintaining QF status. As a preliminary matter, we must determine whether the Act and the subsequent Commission rule changes, which delete the statutory and regulatory ownership constraints, moot the petition for review with respect to this issue.
See Honig v. Doe,
We turn now to the merits, examining the Commission’s order in light of the ownership limitation as it existed at that time. Edison argues the Commission acted arbitrarily and capriciously in permitting Ormesa to sell, over and above its net output, an additional 1.35 MW — corresponding to an amount purchased from another QF to cover Ormesa’s brine-reinjection auxiliary load — without Ormesa’s jeopardizing its QF status. We disagree.
Per the now-defunct statutory ownership restriction, a QF had to be “owned by a person not primarily engaged in the generation or sale of electric power (other than electric power solely from cogeneration facilities or small power production facilities).” 16 U.S.C. § 796(17)(C)(ii)' (2000);
id.
§ 796(18)(B)(ii). In
Turners Falls,
the Commission construed this language to bar a QF from selling nonqualify-ing power over and above its certified net output, and held that such a sale would result in the loss of QF status altogether. 55 F.E.R.C. at 62,671-72. In that case, the Commission had certified the QF’s net output (gross less auxiliary load) as qualifying power.
Id.
at 61,665. However, the QF, which received its auxiliary load from a local utility, sought to sell the nonqualify-ing incremental amount (gross less net) as a nonqualifying facility seller.
Id.
at 62,-666. According to the Commission, such sales of nonqualifying power by QFs are prohibited because the QF would be selling electric power that does not fall within the parenthetical “other than” exception, despite the colorablе argument that even the incremental power — which after all was generated by the QF itself — was “electric power solely from cogeneration facilities or small power production facilities.”
Id.
at 62,667-68 (citation omitted). The Commission emphasized that, in analyzing whether the incremental sale transgresses the statutory ownership restriction, “the most important fact is that the incremental output of the Turners Falls facility
... is not ... qualifying output
eligible for the regulatory exemptions.”
Id.
at 62,671 (emphasis added). Later, in
Connecticut Valley,
the Commission, reiterating the statutory ownership restriction (including the exception thereto) and citing
Turners Falls,
stated that “a sale in excess of net output would deprive a facility of its QF status, unless the incremental sale was of power solely from cogeneration or small
In the present case, citing Connecticut Valley, the Commission determined that, although the 1.35 MW was not part of Ormesa’s net output, Ormesa could nonetheless sell it, provided it would be purchased from another QF. Certification Order, 107 F.E.R.C. at 61,151 n.10. The explanation given, as set forth in a footnote, is as follows:
Ormesa indicates that here the 1.35 MW will be purchased from another QF. In [Connecticut Valley, 82 F.E.R.C. at 61,-418 & n.17], the Commission found that a sale in excess of net output would deprive a facility of its QF status unless the incremental sale consisted of power solely from cogeneration or small power production facilities. Therefore, notwithstanding the discussion above, given that 1.35 MW will be purchased from another QF, Ormesa is permitted to sell an additional 1.35 MW from its facility without jeopardizing its QF status.
Certification Order, 107 F.E.R.C. at 61,151 n.10.
We are not persuaded this footnote represents an improper expansion of the exception to the statutory ownership requirement, as applied in Commission precedent. In citing to Connecticut Valley (which in turn cites Turners Falls), we under-stand the Commission to have extended permission to sell an additional 1.35 MW only insofar as Ormesa purchases a corresponding amount of power from the other QF’s supply of qualifying output. 8 Turners Falls highlighted that the touchstone is whether the incremental power is “qualifying output,” and in that case, unlike the present one, the sale of incremental power was prohibited precisely because it was not qualifying power. 55 F.E.R.C. at 62,671. Similar to Ormesa’s ability to sell its оwn qualifying power, the Commission reasonably permitted Ormesa to, in essence, sell another QF’s qualifying power without putting Ormesa’s QF status at risk. That is, consistent with Commission precedent, the Commission reasonably found that such a sale would not run afoul of the statutory ownership restriction but would instead fall within the exception thereto. Whether Ormesa subsequently exceeded the bounds of the Commission’s permission — by selling non qualifying power — is not a matter before us.

Edison next argues the Commissiоn acted arbitrarily and capriciously in making a distinction between power for brine extraction (which it determined is not part of the auxiliary load) and brine reinjection (which it determined is part of auxiliary load). Edison would adopt the Commission’s conclusion as to reinjection, while rejecting the conclusion as to extraction. Accordingly, Edison contends the Commission must reassess its GEO East Mesa precedent, which directly controlled the categorization of brine extraction. We again disagree.
In
GEO East Mesa,
the Commission held the auxiliary load includes power for those functions that are a “ ‘necessary and integral’ part of the power production process.” 55 F.E.R.C. at 61,813. The Corn-
Applying
GEO East Mesa
in the present case, the Commission concluded that Ormesa’s extraction and transportation activities were not part of the auxiliary load. Edison urges here, as it did before the Commission, that the Commission erred in not overturning
GEO East Mesa.
However, the Commission has adequately explained why it declined to do so, rejecting Edison’s contention that the brine should more properly be seen as “working fluid” (which presumably would have brought all extraction and transportation within the ambit of the auxiliary load), rather than as the “fuel” (for which only “essential fuel handling” functions are part of the auxiliary load).
See Certification Order,
107 F.E.R.C. at 61,151. The Commission determined thе “brine itself is not the working fluid of the facility”; rather, the “working fluid is isopentane.”
Id.
“The brine heats the isopentane and the isopentane functions as the facility’s working fluid, turning the turbines and generators.”
Id.
In short, the Commission offered a reasonable explanation for adhering to
GEO East Mesa. Cf. Southwest Gas Corp. v. FERC,
Edison’s argument that it would be more appropriate to analogize to nuclear and steam power production rather than to coal is unavailing. It is within agency discretion to reasonably analogize to one set of facts rather than another.
See New Charleston Power I, L.P. v. FERC,
Having thus determined, per GEO East Mesa, that brine extraction was not part of Ormesa’s auxiliary load, the Commission then explained its rationale for treating brine reinjection differently:
Following the removal of heat from the brine (to heat the isopentane), the brine is no longer fuel, but is effectively spent fuel. It is undisputed that spent fuel must be disposed of, and here is disposed of by reinjectionf. W]e find that given the type of QF and its configuration such disposal is “necessary and integral” to this QF’s power production process.

Notes
. Congress also sought to relieve some of the regulatory burdens that discouraged development of such facilities by exempting QFs from certain state and federal laws.
See
16 U.S.C. § 824a-3(e);
FERC v. Mississippi,
. This regulation read:
(a) General Rule. A cogeneration facility or small power production facility may not be owned by a person primarily engaged in the generation or sale of electric power (other than electric power solely from cogeneration facilities or small power production facilities),
ib) Ownership test. For purposes of this section, a cogeneration or small power production facility shall be considered to be owned by a person primarily engaged in the generation or sale of electric power, if more than 50 percent of the equity interest in the facility is held by an electric utility or utilities ....
. We offer no comment on the Act's amendments to 16 U.S.C. § 824а-3, which added new subsection (m), allowing for the mandatory purchase and sell requirements to be lifted in certain circumstances, and new subsection (n), directing the Commission to revise the criteria in 18 C.F.R. § 292.205 for new qualifying cogeneration facilities seeking to make sales pursuant to Section 210 of PURPA.

Pub.L. No. 109-58, § 1253(a),
. 19.95 (Gross) — 3.38 (ii) = 16.57(Net).
. 19.95 (Gross) — 3.24 (i) — 3.38 (ii) — 1.35 (iii) = 11.98(Net).
. 19.95 (Gross) — 3.38 (ii) — 1.35 (iii) = 15.22(Net).
. The Commission nowhere stated whether Edison was necessarily compelled to buy this additional amount, only that Ormesa was permitted to sell it without losing QF status. Cf. Connecticut Valley, 82 F.E.R.C. at 61,418 ("[T]he requirement of [18 C.F.R. § ] 292.303(a), that an electric utility purchase any energy and capacity made available from a QF, is limited to the energy and capacity а QF actually has available, which is its net energy and capacity.”).
. Although Ormesa never explicitly claimed in its recertification application that it would purchase the capacity from another QF, see, e.g., Joint Appendix 15-16 (Ormesa “uses power from another geothermal QF” for rein-jection (emphasis added)); id. at 20 (power for reinjection “is provided by another geothermal QF” (emphasis added)); id. at 22 (power for reinjection is ‘‘supplied by another QF” (emphasis added)), the Commission’s permission, by its own terms, only extends "if that additional 1.35 MW were purchased from another QF,” Rehearing Order, 108 F.E.R.C. at 62,514 (emphasis added).
. Although Ormesa argued in its motion for rehearing before the Commission that the Commission's distinction between extraction and reinjection was unsound, Ormesa has not sought our review of the Commission's conclusion that power for reinjection is part of the auxiliary load.
