Dry Fork Station
Location: Gillette, WY
Output: 385 megawatts
Located 7 miles north of Gillette, Wyoming, the Dry Fork Station is a coal-based electric generation power plant owned by Basin Electric (92.9 percent), and the Wyoming Municipal Power Agency, Lusk, Wyoming. (7.1 percent).
Construction on the Dry Fork Station began in 2007, and commercial operation began in 2011. Among many significant milestones, the safety record during construction included more than 6 million man-hours worked without a lost-time accident. The power plant was built for $1.35 billion.
The majority of electricity produced at Dry Fork Station is sent via 125 miles of transmission line to substations in northeast Wyoming, where it connects to the transmission grid.
Sub-bituminous coal from the nearby Dry Fork Mine provides fuel for Dry Fork Station via a conveyor system approximately one mile in length. The station uses pulverized coal technology and the latest generation of pollution control technologies resulting in very low emissions.
The plant used an air-cooled condenser, technology chosen to conserve water resources. It is the largest in North America, and the first application of this kind of cooling technology in Basin Electric's generating fleet.
The water-to-steam-to-water cycle is a closed-loop process, and make-up water is added as needed to maintain water quality and quantity. Dry Fork Station is a zero-discharge facility.
