Hayden Station

Location: Hayden, Colorado

Plant Description: Hayden Station is a coal-fired, steam-electric generating station with two operating units. The plant has three owners, with operational responsibilities held by Xcel Energy. Ownership is as follows: Unit 1 – Xcel Energy (75.5%), PacifiCorp, Portland, Oregon (24.5%) Unit 2 – Salt River Project, Phoenix, Arizona (50%), Xcel Energy (37.4) and PacifiCorp, (12.6%)

Power Production Capabilities: 446 megawatts (MW): Unit 1 – 184 MW and Unit 2 – 262 MW

Fuel Source: Low-sulfur coal trucked from Peabody Coal’s Twenty Mile mine.

Plant History: Unit 1 construction began in 1962, and the unit became operational in 1965. Unit 2 construction began in 1972, and it was placed into service in 1976. Hayden Station was acquired by Public Service Co. of Colorado, a predecessor to Xcel Energy, and the other owners in 1992 from the Colorado-Ute Electric Association.

Interesting Features: Hayden Station discharges no water offsite. The plant is also one of the cleanest coal-fired generating stations in the region with advanced emissions control equipment.

Environmental Highlights: Both units at Hayden Station have three different emissions control systems, including baghouses, dry scrubbing systems and low-NOx burners. Baghouses act like giant vacuum cleaners, removing particulate emissions from the flue gas by more than 99 percent. Dry scrubbing systems reduce sulfur dioxide (SO2) emissions by about 85 percent, and over-fire air equipment reduces nitrogen oxide (NOx) emissions by up to 50 percent.

Community Involvement: Hayden Station employees make significant contributions to the local community through donations to the United Way and by serving on local boards, coaching sports and working as volunteer firefighters, emergency medical technicians and search and rescue team members. The plant also supports a variety of community projects each year in both Routt and Moffatt counties.
