Dry Fork Station, owned by Basin Electric Co-Op and Wyoming Municipal Power Agency in Gillette, Wyo.
Runner Up, Dry Fork Station PRB Coal Fired Power Plant
The $1.35 billion Dry Fork Station was commissioned on November 1, 2011 and is a greenfield leading edge coal-fired power plant. It was built to add capacity to meet the needs of the 134-member co-ops of Basin Electric and WMPA. The minemouth plant uses Power River Basin coal. The project had a construction and commissioning timeline of 45 months and finished on budget and two months ahead of schedule.
The project used circulated fluidized boiler (CFB) scrubber technology relatively unknown in the U.S. and untried worldwide at this size. An air cooled condenser minimizes water usage with 45 fans 100 feet off the ground condensing steam for reuse. The plant also uses an advanced control protection technology using foundation field bus for all station-wide systems to protect personnel, cost control and reliability requirements.
