Microsoft Corp. will buy wind power from a new Illinois wind farm for the next 20 years to offset its power needs, part of a plan by the technology company to become offset its carbon output.
The 175-megawatt wind farm is under construction 60 miles outside Chicago at the border of Kankakee and Iroquois Counties. It's 96 percent owned by EDF Renewable Energy, a U.S. subsidiary of French utility Electricite de France SA.
The wind farm will flow power onto the same same electric grid that powers Microsoft’s Chicago area datacenter and is expected to begin operating in 2015. The project is expected to supply enough electricity to power 70,000 homes in Illinois.
