Located seven miles northwest of Beulah, North Dakota, the Antelope Valley Station's two units, each rated at 450 megawatts, began commercial operation in 1984 and 1986, respectively. The power plant was built for $1.9 billion.
Because of its location next to a lignite coal mine (The Coteau Properties Company's Freedom Mine) from which it receives its fuel, Antelope Valley Station is referred to as a "mine-mouth" facility.
Antelope Valley is part of a $4-billion energy complex that includes the Great Plains Synfuels Plant and the Freedom Mine. A majority of Antelope Valley Station's fuel supply is provided by the Great Plains Synfuels Plant in the form of lignite fines - particles of coal too small for use in the gasification process.
The water source for Antelope Valley Station is Lake Sakakawea, a large reservoir on the Missouri River. Water is used efficiently, and a plant-water balance system is based on a philosophy of maximum reuse.
