The 200-megawatt (MW) wind farm, located in Converse County, supplies wind energy to PacifiCorp under the terms of a 20-year power purchase agreement. The 110 wind turbines that comprise the Top of the World project are capable of producing enough electricity to power approximately 60,000 homes.
Top of the World is Duke Energy's fourth – and largest – wind farm in Wyoming. The company's 99-MW Campbell Hill Windpower Project in Converse County came on line in 2009. Duke Energy also owns and operates two wind farms near Cheyenne: the 29-MW Happy Jack Windpower Project, which began commercial operation in 2008, and the 42-MW Silver Sage Windpower Project, which came on line in 2009.
