Antelope Valley Station (AVS) is a lignite-based electric generating station with two pulverized tangentially fired boilers. AVS provides baseload electric service, operating 24 hours a day, seven days a week. AVS is owned and operated by Basin Electric Power Cooperative, headquartered in Bismarck, ND.
Power production capability:
900 megawatts. The station has two units rated at 450 megawatts each.
AVS annually consumes more than 5 million tons of lignite supplied from the nearby The Coteau Properties Company.
AVS was constructed at a cost of $1.9 billion. The first unit began commercial operation in July 1984 and the second unit in June 1986.
Antelope Valley Station was designed to be environmentally sound. More than $319 million has been invested for environmental controls. Dry scrubbers use lime to capture and remove up to 90 percent of sulfur dioxide emissions from stack gases. Fabric filter bag houses capture and remove up to 99 percent of particulate matter. Each bag house contains more than 8,000 35-foot tall bags. Antelope Valley is a “zero-discharge” facility. Water is used efficiently. The only way water that leaves the plant site is through evaporation.
In 2009, AVS received a $100 million cooperative grant from the U.S. Department of Energy to implement a technology to capture carbon dioxide from one of the units.
