The wind farm is expected to be up and running by the first half of 2015. Apex Clean Energy, a green power company in Charlottesville, Va., is building and running the project.
Steve Howard, chief sustainability offer at Ikea, said the investment will be good for the company's business and the nation's energy independence.
"The U.S has amazing wind and sun resources that will never run out," he said.
The wind farm will eventually produce enough energy to power 34,000 average U.S. homes or 18 percent of all the electricity used by the company around the world, Ikea said.
