On October 22, 2014, the U.S. General Services Administration (GSA) announced that it is on track to meet the Administration's 2020 renewable energy goal after awarding a competitive power supply contract to a commercial wind developer for the purchase of 140 megawatts (MW) of clean wind energy. The energy will come from the Walnut Ridge Wind Farm, which is currently in development in northwest Illinois, and will add more than 500,000 megawatt-hours (MWhs) of electricity to the power grid annually. The ten-year contract was awarded to MG2 Tribal Energy – a joint venture between the Mesa Grande Band of Mission Indians, a federally-recognized Native American tribe, and Geronimo Energy, a commercial wind developer – and is the largest wind energy purchase from a single source in federal contracting history.
