Opinion for the Court filed by Circuit Judge ROGERS.
Arkansas Electric Energy Consumers and others
1
рetition for review of Opinion Nos. 385 and 385-A of the Federal Energy Regulatory Commission. In those opinions the Commission approved the merger of the Entergy and Gulf States systems under § 203 of the Federal Power Act (“FPA”), 16 U.S.C. § 824b, and an amendment to the Entergy System Agreement under FPA '§ 205, 16 U.S.C. § 824d, to add Gulf States as an Entergy Operating Company upon approval and consummation of the merger.

Opinion No. 385,
I.
Opinion Nos. 385 and 385-A respond to the 1992 filing by Entergy and Gulf States of a joint application under § 203 for authorization to merge their adjacent systems. Entergy simultaneously filed, pursuant to § 205, a proposed amendment to the System Agreement to add Gulf States as an EOC upon approval and consummation of the merger. The background to these proceedings need not be repeated.
See City of New Orleans v. FERC,

The FPA provides for rehearing of a Commission order, provided the request is

filed within 30 days of the order. 16 U.S.C.’ § 8252(a). Thereafter, a party or othеr person aggrieved has 60 days from the denial of rehearing to seek judicial review.

§ 8252(b). Application for rehearing by the Commission is a prerequisite to seeking judicial review.
Id.
§ 8252(a). No objection to the Commission’s order may be raised on appeal to the court unless it was urged before the Commission on rehearing “unless there is reasonable ground for failure to do so.”

See FPC v. Colorado Interstate Gas Co.,
In the order setting forth the issues to be addressed at an evidentiary hearing, the Commission stated, in relevant part, that the § 205 inquiry would “focus solely on whether the Operating Companies and their customers will be adversely affected by Gulf States’ integration into the existing System Agreement. ...”

Upon determining that, in petitioners’ view, the opinion of the Administrative Law Judge (“ALJ”) following the eviden-tiary hearing,
Initial Decision,
In now contending that petitioners are making an impermissible collateral attack on the “adverse effects” test established in the Hearing Order, the Commission relies on
Bluestone Energy Design, Inc. v. FERC,
Because petitioners have argued throughout the proceedings before the Commission, on the appropriate occasions, that its members will be “adversely affected” unless intrasystem adjustments are made, we hold that petitioners have preserved their §§ 203 and 205 contentions for judicial review under 16 U.S.C. § 825Z(b).
III.
Section 205(a) of the FPA provides that “[a]ll rates and сharges made, demanded, or received by any public utility for or in connection with the sale of electric energy subject to the jurisdiction of the Commission ... shall be just and reasonable, and any such rate or charge that is not just or reasonable is hereby declared unlawful.” 16 U.S.C. § 824d(a). Section 205(b) provides that it shall be unlawful for a public utility, with respect to any transmission or sale subject to the jurisdiction of the Commission, to “(1) make or grant any undue preference or advantage to any person ... or (2) maintain any unreasonable difference in rates, charges, services, facilities, or in any other respect, either as between localities or as between classes of service.” Id. § 824d(b). Petitioners contend that in approving the addition of Gulf States to thе System Agreement without modifying the Agreement’s rate formulas to reflect Gulf State’s lack of prior contribution to the costs of the Entergy system, the Commission acted unlawfully in violation of § 205. Petitioners point to Opinion Nos. 234 and 292 2 where, they maintain, the Commission set forth the principle that prevention of undue discrimination requires attention to historical patterns of cost-bearing on the Entergy system. Because the EOCs share a common history of planning and cost-sharing for system generation facilities, petitioners maintain that to avoid undue discrimination Gulf States should not be permitted to benefit from the advantageous rate schedules in the System Agreement after most of the depreciation costs have been paid. Specifically, petitioners proposеd to the Commission that Gulf States be required to make MSS-1 3 payments to the “long” EOCs 4 of approximately $80 million while receiving fuel benefits from the EOCs’ coal units of approximately $115-223 million, and that *367 the EOCs, as to MSS-3, 5 be given first priority to low-cost energy in the system pool. In sum, petitioners contend that in rejecting this proposal, the Commission arbitrarily disregarded its precedent and the relevant historical setting.
In reviewing the Commission’s deсisions, the court’s role is limited to determining whether the Commission complied with the relevant FPA standards and demonstrated that it has made a reasonable decision based on substantial evidence in the record.
See Sithe/Independence Power Partners, LP v. FERC,
The Commission found, and petitioners do not dispute, that the merger would produce net benefits to all of the EOCs and to Gulf States, including significant savings of net production costs and non-fuel operations and management expenses.
Opinion No. 385,
Petitioners rely on
Alabama Elec. Coop. v. FERC,
As evidence of undue discrimination, petitioners point to their lost opportunity to benefit from open market sales of excess capacity, instead of being obligated under the System Agreement to afford Gulf States access to such capacity through the system pоol at below-market rates. They also point to the loss of their ability to take advantage of depreciation avoidance, whereby, for example, Arkansas Electric Energy Consumers asserts that it has fully depreciated generating plants, the front-end costs of which have been borne by the EOCs’ ratepayers. Yet these circumstances do not demonstrate unduly dispаrate treatment between Gulf States and the Entergy EOCs with respect to intrasystem energy exchanges or capacity equalization payments. As the ALJ pointed out, petitioners ignore the generation that Gulf States brings to the Entergy power pool.
Initial Decision,
Nor do petitioners show exceptional cost circumstances here (namely, enormous disparities in per-megawatt costs) as were at issue in Opinion Nos. 234 and 292, when the Commission imposed a rough equalization of each operating company’s investment in the system’s nuclear generating facilities due to exorbitant and unforeseen cost overruns at the Grand Gulf facility.
See Mississippi Indus.,
Nor, contrary to petitioners’ contention, does the Commission’s rejection of petitioners’ proposed modifications to the amended System Agreement indicate that the Commission unlawfully applied a § 203 standard to a § 205 issue. Although the Commission’s rationale in Opinion No. 385 for rejecting petitioners’ MSS-1 and MSS-3 proposals is at times turgid,
see, e.g., Opinion No. 385,
Thereforе, because the Commission adhered to established practice on the Enter-gy System in subjecting Gulf States to virtually the same System Agreement terms as the EOCs, and petitioners fail to show, given the relationship of the System Agreement amendment to the merger, that the Commission’s decision was unreasonable, not based on substantial evidence in the record, or otherwise unclear in the path of its reasoning,
see Sithe,
IY.
Petitioners’ contention that the Commission improperly disposed of the competition ■ issue without an evidentiary hearing is also unavailing. Petitioners identify no material issue of fact that could not be properly resolved by the Commission on the written record and thus fail to show that its decision to forego an eviden-
*370
tiary hearing was an abuse of discretion.
See Moreau v. FERC,
Consistent with the public interest standard for mergers, 16 U.S.C. § 824b(a);

Accordingly, we deny the petitions for review.
