Procedural History

• District Court, May 16, 2019: Issued the decision under analysis, which is an appeal from the New Mexico Public Regulation Commission granting part of the increase in retail electric rates sought by PNM (para 1).

Parties' Submissions

• Appellant (PNM): Argued that the Commission’s denial of recovery for certain costs and decisions regarding rate adjustments were unreasonable and unlawful.
• Appellee (New Mexico Public Regulation Commission): Defended its final order as a lawful and reasonable exercise of its regulatory authority.
• Interveners-Appellees/Cross-Appellants (Various): Raised issues with the Commission’s final order, including challenges to decisions on specific energy generating stations and rate adjustments.

Legal Issues

• Whether the Commission’s decisions regarding Palo Verde, San Juan Generating Station, Four Corners Power Plant, Rate 11B, the prepaid pension asset, and the adoption of Method A were lawful and reasonable.
• Whether the denial of any future recovery for nuclear decommissioning costs violated PNM’s right to due process of law.

Disposition

• The Supreme Court of the State of New Mexico vacated and annulled the Commission’s final order in its entirety due to a violation of PNM’s right to due process of law concerning the denial of any future recovery for nuclear decommissioning costs.

Reasons

• The Supreme Court found that the Commission’s decisions were largely supported by substantial evidence and within its authority, except for the denial of any future recovery for nuclear decommissioning costs, which violated PNM’s right to due process of law. The Court concluded that the Commission’s decision on Palo Verde was supported by substantial evidence and that its remedies for PNM’s imprudence were reasonable and lawful. However, by denying PNM any future recovery for its nuclear decommissioning costs related to the Palo Verde capacity, the Commission denied PNM due process of law, necessitating the annulment and vacation of the final order in its entirety. The case was remanded to the Commission for further proceedings consistent with the opinion.
