Black Hills Corp. (BKH) announced that Wygen III, Black Hills Power's 110 MW coal-fired generation facility near Gillette, Wyo., began commercial operations.
Construction of the facility took less than 24 months to complete. The mine-mouth coal-fired power plant is expected to be in service for 45 years.
On March 16, 2010, Black Hills Power completed a seven-year power purchase agreement with the City of Gillette, Wyo. which includes an option for Gillette to purchase 23 percent of Wygen III. Montana-Dakota Utilities previously purchased a 25-percent ownership interest in Wygen III in April 2009.
