New Mexico regulators on Wednesday unanimously approved a plan to add renewable energy and storage to replace a portion of the San Juan Generating Station’s capacity owned by Public Service Company of New Mexico (PNM). The portfolio includes 650 MW of new solar resources and 300 MW of battery storage, totaling over $1 billion in investments within the districts impacted by the San Juan plant closure. PNM, the state’s largest utility and majority owner of the San Juan plant, had recommended a “hybrid” replacement scenario that would have allowed the utility to add 280 MW of gas-fired power alongside wind, solar and battery storage to replace its 497 MW retail share of the plant. Regulators’ decision to choose the all-renewables portfolio was “basically unavoidable,” Public Regulation Commissioner Cynthia Hall told Utility Dive. A 100% renewables portfolio was the only replacement option that fully satisfied the state’s Energy Transition Act (ETA), passed last year, which requires the state to make an economically just transition to 100% carbon-free energy by 2045, she said.
