Corridor Business Journal: Alliant Energy has announced the completion of its plan to add 1,000 megawatts of wind production in Iowa, several months ahead of schedule. The milestone comes as the company completes its 130-MW Richland Wind Farm in Sac County in west-central Iowa. Alliant now counts five wind projects in the state, producing nearly 1,300 MW in total – roughly enough to power 430,000 Iowa homes, and making it the third-largest utility owner-operator of regulated wind in the United States.
