The largest coal plant in the Western United States will keep operating through 2019 after its owners received approval from the federal Bureau of Reclamation and Bureau of Indian Affairs to extend its lease on Wednesday. The plant's owners, including Reclamation and a group of utilities, had planned to close the 2,250 MW Navajo Generating Station (NGS) in 2018. The Navajo Nation, which owns the land on which the plant sits, voted to extend its lease until 2019, but needed final approval from the federal agency. Arizona utility Salt River Project (SRP) and other owners still plan to shutter the facility after its lease expires, citing competitive pressures from cheap natural gas. The Navajo Nation and coal supplier Peabody Energy are working to find a new owner for the plant.
