Who would have guessed?… The city of Boulder is a hydroelectric power generator. On May 21, 2018 the city signed a contract with Tri-State Generation and Transmission Association for the sale of hydroelectric power generated at the Boulder Canyon, Orodell, Sunshine, Maxwell and Kohler hydroelectric plants. The estimated revenue of $500,000 a year will be used for water utility capital improvements and operating costs.
The City of Boulder owns and operates eight hydroelectric power plants, with one purchased and seven constructed since 1985. These facilities were installed on existing water supply pipelines without any additional dams or overhead transmission lines. Total generation for 2016 was 40,798,941 kilowatt hours (kWh)
Tri-State is the not-for-profit, cooperative power supplier to 43 electric distribution cooperatives and public power districts in Colorado, Nebraska, New Mexico and Wyoming.
