Facts

• The case involves challenges to the Public Regulation Commission's (PRC) Final Order amending its Energy Efficiency Rules to comply with the Efficient Use of Energy Act (EUEA). The amendments were aimed at identifying and removing regulatory disincentives to public utilities' implementation of energy efficiency programs. The Attorney General (AG) and the New Mexico Industrial Energy Consumers (NMIEC) appealed the PRC's Final Order, leading to the consolidation of their appeals for this decision (paras 1-3).

Procedural History

Parties' Submissions

• Appellant Attorney General of the State of New Mexico: Challenged the PRC's Final Order on several grounds.
• Appellant New Mexico Industrial Energy Consumers: Similarly challenged the PRC's Final Order.
• Appellee New Mexico Public Regulation Commission: Defended its Final Order, arguing that the EUEA does not require adder rates to be cost-based and suggesting that the Legislature intended to allow rates created under the EUEA to ignore the cost-based requirement of rates created under the Public Utility Act (PUA) (paras 12-13).
• Intervenors (Public Service Company of New Mexico, Western Resource Advocates, and Coalition for Clean Affordable Energy): Their specific submissions are not detailed in the provided text.

Legal Issues

• Whether the PRC's Final Order amending its Energy Efficiency Rules to comply with the EUEA was arbitrary, not supported by substantial evidence, outside the scope of the agency’s authority, or otherwise inconsistent with law (para 9).
• Whether the adder rates contained in Alternative A were "just and reasonable" as required by law (paras 11-18).

Disposition

• The Supreme Court of New Mexico annulled and vacated the PRC’s Final Order due to the lack of a lawful basis in the record to support its decision (para 19).

Reasons

• The Supreme Court, with Justice Patricio M. Serna authoring the opinion, held that the PRC's Final Order was inconsistent with the law because it did not follow the required balancing test to determine if the rates were "just and reasonable." The Court found that the PRC concluded rates created under the EUEA do not need to be cost-based without inquiring into any of the utilities' revenue requirements or the traditional elements of the ratemaking process. This approach was deemed arbitrary and unlawful as it was not evidence-based, cost-based, nor utility-specific. The Court emphasized that both the EUEA and the PUA require the PRC to balance the public interest, consumers’ interests, and investors’ interests when setting rates. The decision was unanimous with Chief Justice Charles W. Daniels, Justices Petra Jimenez Maes, Richard C. Bosson, and Edward L. Chávez concurring (paras 12-18).
