GM will source wind power through an agreement with Renewable Energy Systems, a global renewable energy and energy storage development and construction company. GM will purchase 50 megawatts of power produced at Cactus Flats, a 150-megawatt wind farm being developed by RES in Concho County, Texas. When the contract begins in the first half of 2018, 6% of GM’s global energy use will be powered by renewable energy.

Starting in 2018, GM will source more than 193,000 MWh of electricity from wind annually, enough to power the Austin IT Innovation Center, a GM Financial office in Fort Worth and 13 parts warehouses. GM Arlington Assembly, which is already 50% powered by renewable energy, will have all of its electricity needs met with green power.

GM worked with Altenex, an Edison Energy Company and an independent renewable energy advisor, to identify renewable energy projects in the Texas market and execute the deal.

GM announced the purchase at a Business Renewables Center meeting at GM’s global headquarters at the Detroit Renaissance Center. GM is a founding member of the BRC, an organization backed by the Rocky Mountain Institute that streamlines and accelerates corporate purchasing of wind and solar energy.

In addition to an anticipated 114 megawatts of wind power, GM hosts 24 solar installations around the world and is the Nº 1 automotive user of solar energy in the US, according to a report released this month by the Solar Energy Industries Association.
