N.M. Att’y. Gen. v. N.M. Pub. Regulation Comm’n

The Public Regulation Commission (PRC) granted Southwestern Public Service Company’s (SPS) application to: (1) include a prepaid pension asset in its rate base in order for SPS to earn a return on this asset; and (2) obtain a renewable energy cost rider to recover approximately $22 million of renewable energy procurement costs from those customers who did not have a legislatively imposed limit on their renewable energy costs (non-capped customers). The Attorney General appealed the PRC’s final order granting SPS’s application, arguing that the approved rates were unjust and unreasonable because the inclusion of the entire prepaid asset in the rate base was not supported by substantial evidence, and the PRC acted contrary to law in allowing SPS to recover the aforementioned renewable energy costs from non-capped customers. After review, the Supreme Court affirmed the PRC because: (1) SPS was entitled to earn a reasonable rate of return on the investor-funded prepaid pension asset; and (2) SPS could recover its renewable energy costs in excess of the large customer cap from non-capped customers because such a recovery mechanism was the only viable method of cost recovery that was consistent with the purposes of the Renewable Energy Act.
