Investor-owned utility (IOU) Public Service Company of New Mexico (PNM) is seeking regulatory approval of two Energy Storage Agreements (ESA) and a Certificate of Convenience and Necessity (CCN) covering 350MW of energy storage capacity across three projects.

The projects were selected by PNM after a “robust and competitive” RFP process issued by the IOU to meet summer 2028 retail customer needs in the most cost-effective and reliable way. PNM lodged a filing with the New Mexico Public Regulation Commission (NMPRC) containing details of the agreements on 22 November 2024.
