"The mix may also include energy storage, depending on the economics of the proposals PNM receives through a solicitation that the company will conduct as described in the four-year action plan," PNM said in its plan. " New Mexico 's utility regulators have proposed to end all coal - fired energy generation by 2031 . The Integrated Resource Plan , initially proposed by the Public Service Company of New Mexico ( PBS ) , recommends the closure of the 847 MW San Juan coal plant by 2022 as well as winding up its ownership stake in the Four Corners coal plant by 2020 . The energy generation capacity is likely to be replaced by a combination of solar power and natural gas , making PNM close to 70 % emissions free by 2032 , while allowing it to move from expensive , fixed - cost coal schemes towards more load - flexible plans .
