Wygen III Power Plant, Wyoming

STATUS: Complete

TYPE: Coal

OPPOSITION: Sierra Club, Powder River Basin Council


BACKGROUND:  The developer proposed construction of a 110 megawatt, $255 million coal unit at an existing power plant near Gillette, Wyoming in 2006. In March 2007, the state Department of Environmental Quality (DEQ) issued a final air permit. In March 2008 the developer obtained a Certificate of Public Convenience and Necessity issued by the Wyoming Public Service Commission in March 2008 and began construction. Construction was completed in late 2009 and the unit was fully operational in April.

Sierra Club and others opposed the plant based on its alleged CO2 and hazardous air pollutant emissions, its water and wildlife impacts, and the increased electrical rates attributable to its construction.   The opponents, however, did not challenge the State approvals in court
