Draft stipulation agreement reflects interests of PNM, AVANGRID and 13 other signatories to bring over $270 million in benefits to New Mexico;

New Mexico regulatory approval is last remaining approval required for merger

On Friday, May 28, the Hearing Examiner for the New Mexico Public Regulation Commission (NMPRC) set the remaining procedural schedule for the amended stipulation in the merger application between the parent company of the Public Service Company of New Mexico (PNM), PNM Resources, Inc. (NYSE: PNM) and AVANGRID, Inc. (NYSE: AGR). This schedule comes after AVANGRID submitted materials that addressed the Hearing Examiner’s questions about its Northeastern regional utility subsidiaries regarding service quality standards, including details on routine management audit reviews that are typical for investor-owned utilities in those jurisdictions. The filing demonstrated that AVANGRID utilities’ storm preparedness and response compared favorably to other utilities in the region.

“We are very pleased with the hearing examiner’s decision to allow the stipulated agreement to be heard,” said Dennis V. Arriola, CEO of AVANGRID. “The support of so many entities from New Mexico as well as individuals is encouraging. We continue to listen to stakeholders and we hope additional parties will sign on to the stipulation in support of the merger.”

The procedural schedule sets August 11 – 20, 2021 as the dates for evidentiary hearings on the stipulated agreement among PNM, AVANGRID and 13 other parties representing diverse interests which will bring many benefits to the state, including over $270 million in benefits to New Mexico.

Parties supporting the amended stipulated agreement include: the Attorney General of the State of New Mexico, Western Resource Advocates, the International Brotherhood of Electrical Workers Local 611, Dine Citizens Against Ruining Our Environment, Nava Education Project, San Juan Citizens Alliance, To Nizhoni Ani, the Coalition for Clean Affordable Energy, Interwest Energy Alliance, Walmart, Inc., Onward Energy Holdings, LLC, M-S-R Power and Los Alamos County.

The customer benefits in the stipulation include:

• $50 million in customer rate credits over three years;
• $6 million in COVID arrearages relief for customers;
• $15 million for low-income customer energy-efficiency assistance; and
• $2 million to bring electricity to low-income, remote customers.

The stipulation includes additional economic development for New Mexico:

• 150 new full-time jobs over three years that will remain no less than five years thereafter;
• $7.5 million in additional economic development funds;
• $12.5 million in economic development contributions to community groups in the Four Corners region over five years ($2.5 million/year);
• Improvements to the energy transition displaced worker assistance fund relating to the closure of the San Juan Generating Station; and
• Free access to streetlighting poles for local governments for wireless internet access for three years.

To date, AVANGRID has received six governmental approvals for the merger. Five federal agencies and the Public Utility Commission of Texas have already completed their reviews and approved the proposed merger, leaving the NMPRC as the only remaining approval necessary for the merger. The original application before the NMPRC was filed in November 2020.
