Site description

Cherokee Station is an 801-MW facility owned and operated by Xcel Energy. Built in 1968, it was previously composed of four coal-fired units: Units 1 and 2 were shut down in 2011-2012 to be converted to natural gas in 2015; Unit 3 was shut down in 2015; and Unit 4 was converted to natural gas in 2017. Cherokee station is in Denver, Colorado in Denver County where 61,559 people live within a 3-mile radius of the plant. The plant has four units regulated under the federal coal ash rule: the West, Center, and East bottom ash impoundments, which closed in 2018, and the Cooling Tower Retention Pond, which closed in 2017.
