context_page_description: The Four Corners Generating Station is a coal-fired power plant located near Fruitland, New Mexico, on property located on the Navajo Nation that is leased from the Navajo Nation government.
context_section_description: The Four Corners Generating Station originally consisted of five units with a total rated generating capacity of about 2,040 megawatts. Units 1, 2, and 3 (permanently shut down in 2014 as part of a $182 million plan for Arizona Public Service Co. to meet environmental regulations) had a combined generating capacity of 560 megawatts while units 4 and 5 each have a generating capacity of 770 MW. Units 1, 2 and 3 opened in 1963–64 and Units 4 and 5 opened in 1969–70.
  The Arizona Public Service Company (APS) owned 100% of Units 1, 2, and 3, while Units 4 and 5 are operated by APS but owned by around five companies, with APS owning 70% in 2014, Public Service Company of New Mexico 13%, Salt River Project 10%, and Tucson Electric Power 7%. The station is cooled using water from Morgan Lake, which is man-made and is replenished by about 28 million gallons of water each day from the San Juan River. The plant burns sub-bituminous coal delivered from the nearby Navajo Coal Mine by the Navajo Mine Railroad.
  The Navajo Transitional Energy Company (NTEC) bought the mine from BHP, three mines in Montana and Wyoming, and 7% of Four Corners Generating Station. In 2020, Arizona Public Service announced plans to decommission the Four Corners Generating Station, leaving no prospect for the mine and the railroad.
