Facts

• The case revolves around the New Mexico Public Regulation Commission's (PRC) authority to consider expenses incurred by a public utility for energy efficiency programs when determining public utility electricity rates. The appellants, the New Mexico Attorney General and New Mexico Industrial Energy Consumers, challenged the PRC's final order that allowed Public Service Company of New Mexico (PNM) to earn returns on operating expenses from energy efficiency programs, arguing it was inconsistent with New Mexico law (paras 1, 13).

Procedural History

• N.M. Pub. Regulation Comm’n, Final Order Repealing and Replacing 17.7.2 NMAC, Case No. 08-00024-UT (April 8, 2010): The PRC adopted proposed Alternative A, revising energy efficiency regulations effective May 3, 2010 (para 5).
• N.M. Pub. Regulation Comm’n, Final Order Partially Adopting Recommended Decision, Case No. 10-00280-UT (June 23, 2011): The PRC issued a final order further reducing the Reduced Adder rates by sixty percent for PNM (para 6).
• Attorney General v. New Mexico Public Regulation Commission (AG v. PRC 2011), 2011-NMSC-034: The Supreme Court vacated the PRC’s Case 024 Final Order for not adequately balancing investors' interests against ratepayers' interests (para 7).

Parties' Submissions

• Appellants: Argued that the PRC's final order permitting PNM to earn returns on energy efficiency program expenses is inconsistent with New Mexico law and the Supreme Court's previous ruling in AG v. PRC 2011. They contended that the PRC acted outside its authority and that the order was unsupported by substantial evidence and arbitrary (paras 8, 13, 28).
• Appellee (PRC): Defended the final order, asserting it was consistent with the PRC’s ratemaking authority under the New Mexico Public Utility Act and the New Mexico Efficient Use of Energy Act. The PRC argued that the order was evidence-based, cost-based, utility-specific, and balanced the interests of the public, consumers, and investors (paras 12, 17, 18).

Legal Issues

• Whether the PRC has the authority to consider expenses incurred by a public utility for energy efficiency programs when determining public utility electricity rates (para 1).
• Whether the PRC's final order is consistent with New Mexico law, specifically the New Mexico Public Utility Act and the New Mexico Efficient Use of Energy Act, and the Supreme Court's ruling in AG v. PRC 2011 (paras 13, 19).
• Whether the PRC's final order is supported by substantial evidence and is neither arbitrary nor capricious (paras 28, 32).

Disposition

• The Supreme Court affirmed the PRC's final order, holding that it is consistent with the PRC’s ratemaking authority, supported by substantial evidence, and neither arbitrary nor capricious (para 35).

Reasons

• The Supreme Court, per Justice Charles W. Daniels, concluded that the PRC's final order was lawful and reasonable. The Court found that the PRC's decision was within its authority under the relevant statutes, was based on a proper balancing of interests, and was supported by substantial evidence from the record of a related case. The Court clarified that the PRC has discretion in determining the appropriate method for establishing just and reasonable utility rates and that the PRC lawfully exercised its discretion in this case. The Court rejected the appellants' interpretation of the term "profit" and affirmed the broader ordinary meaning, which does not necessarily tie profit to capital investment. The decision underscores the PRC's broad discretion in ratemaking and its mandate to balance various interests while promoting energy efficiency (paras 12-34).
