Duke Energy says it has brought a 99-megawatt wind farm on line in Converse County.
The Campbell Hill project's 66 turbines produce enough electricity to power about 30,000 homes each year.
Duke says the project will supply wind energy to PacifiCorp under a 20-year purchase agreement.
Duke Energy also has announced plans to build a 200-megawatt wind power project near Casper next year.
