Facts

The Public Service Company of New Mexico (PNM) sought regulatory abandonment and decertification of its 26.10% interest in Unit 4 of the San Juan Generating Station (SJ-4) and related facilities. PNM argued that the asset was excluded from its rate base due to excess capacity and was no longer required for public convenience and necessity. SJ-4, which began operation in 1982, was initially certified with a projected useful life of 40 years, but PNM faced excess capacity due to overestimated demand and long-term power purchase commitments (paras 1-2, 5).

Procedural History

• Re Public Service Co. of New Mexico, 101 PUR4th 126 (N.M.(P.S.C.) 1989): The New Mexico Public Service Commission excluded certain assets, including 130 megawatts of SJ-4, from PNM's rate base due to excess capacity (para 4).
• Public Service Co. of New Mexico v. New Mexico Public Service Commission, 111 N.M. 622, 808 P.2d 592 (1991): The New Mexico Supreme Court affirmed the Commission's decision in the excess capacity case (para 4).

Parties' Submissions

• Appellant (PNM): Argued that the exclusion of SJ-4 from its rate base in the excess capacity case necessitated its decertification. PNM claimed that continued regulation of SJ-4 was inconsistent with its exclusion from the rate base and violated due process and takings clauses under the New Mexico and U.S. Constitutions. PNM also contended that the Commission improperly applied the "public convenience and necessity" standard and failed to consider alternative energy sources (paras 7, 10, 16, 20, 23).
• Appellee (New Mexico Public Service Commission): Asserted that PNM failed to meet its burden of proof to show that SJ-4 was no longer required for public convenience and necessity. The Commission argued that SJ-4 remained a valuable resource for future energy needs and that continued regulation was consistent with constitutional standards. It also emphasized that PNM did not provide sufficient evidence of financial harm or viable alternatives to SJ-4 (paras 8, 18-19, 30).

Legal Issues

• Whether PNM met the statutory requirements for decertification under NMSA 1978, Section 62-9-5 (para 9).
• Whether the Commission's refusal to decertify SJ-4, while excluding it from PNM's rate base, violated due process or constituted an unconstitutional taking under the New Mexico and U.S. Constitutions (para 9).

Disposition

• The New Mexico Supreme Court affirmed the Commission's decision to deny PNM's application for regulatory abandonment and decertification of its 26.10% interest in SJ-4 (para 31).

Reasons

Per Ransom J. (Sosa C.J. and Baca J. concurring):

• Statutory Requirements for Decertification: The Court held that PNM failed to meet its burden under Section 62-9-5 to demonstrate that public convenience and necessity no longer required regulation of SJ-4. The Commission reasonably applied the "public convenience and necessity" standard, including the four factors from Commuters' Committee v. Pennsylvania Public Utility Commission, which balanced the utility's losses against public hardship and the availability of alternatives. The Court found the Commission's interpretation of the statute to be a permissible exercise of its legislative mandate (paras 10-12, 15-19).

• Constitutional Claims: The Court rejected PNM's due process and takings arguments. It found no evidence of financial harm or uncompensated taking resulting from continued regulation of SJ-4. The Court applied the "end result" test from Federal Power Commission v. Hope Natural Gas Co. and Duquesne Light Co. v. Barasch, concluding that the Commission's actions were neither arbitrary nor discriminatory. The Court also dismissed PNM's reliance on the outdated "public interest" test from Munn v. Illinois, emphasizing that modern due process analysis under Nebbia v. New York focuses on whether regulation is reasonable and not arbitrary (paras 20-28).

• Public Interest in SJ-4: The Court agreed with the Commission's finding that SJ-4 remained an economical and valuable resource for future energy needs. Decertification would deprive consumers of its benefits, and PNM failed to provide sufficient evidence of viable alternatives or financial harm. The Commission's decision to retain regulatory control over SJ-4 was consistent with its broader mandate to balance the interests of utilities and consumers (paras 29-30).

The Court affirmed the Commission's decision, finding it to be a reasonable and lawful exercise of its regulatory authority (para 31).
