Legal decision on Avangrid-PNM merger still pending

Sep. 16—The state Supreme Court said it will continue reviewing a Public Regulation Commission decision to reject Public Service Co. of New Mexico and energy giant Avangrid's proposed merger after listening to oral arguments in the case Friday morning.

The five court justices could have immediately ruled in a bench order on whether to uphold the PRC's December 2021 rejection of the merger, or instead remand the case back to the PRC for reconsideration. But the court said it will consider the evidence presented in Friday's oral arguments before reaching a final decision.

"The arguments were well done by all parties," Chief Justice C. Shannon Bacon told the court at the close of discussion. "We'll get you a decision as soon as possible."

That likely means a final court order won't be released for another three months or more, possibly by late December or early 2024, according to lawyers familiar with Supreme Court proceedings.

PNM and Connecticut-based Avangrid appealed to the Supreme Court in early 2022 to overturn the merger rejection by the previous five-member elected commission that ruled on the case in 2021. Those commissioners concluded that the deal was not in the best interest of New Mexico ratepayers. They said customers could face a deterioration in service based on allegedly "poor performance" by Avangrid utilities operating in some northeastern states.

Confidential reports submitted to the PRC about a criminal investigation in Spain involving one top-level executive at Avangrid's parent firm, Spanish company Iberdrola S.A., also heavily influenced the commissioners against the merger.

Avangrid and PNM, however, say the PRC based its conclusions on "hearsay" from out-of-state witnesses the merger partners never got a chance to cross-examine in PRC hearings, and on third-party reports submitted into the regulatory record by merger opponents.

Avangrid attorney Tom Bird told the justices that such "hearsay" is impermissible as evidence, and its influence on PRC commissioners merits remanding the case back to the PRC for rehearing.

In addition, Bird said the commissioners dismissed out of hand a broad number of merger benefits for ratepayers — plus structural agreements to hold Avangrid accountable regarding service performance — that were written into a settlement, or "stipulation" agreement, negotiated with many parties in the case. That stipulation led 23 of the 24 intervening parties to either directly support the merger or not oppose it.
