The world’s largest manufacturer of office furniture will soon offset 70 percent of its total U.S. electricity usage with wind power from a long-term virtual power purchase agreement (PPA). Steelcase, based in Grand Rapids, Michigan, just announced an agreement with Apex Clean Energy for 25 MW of wind power. Under the 12-year PPA, Steelcase will support the production of power from Apex’s Grant Plains Wind Project, a 150-MW facility in Grant County, Oklahoma, scheduled to come online at the end of this year.

Apex Clean Energy was the market leader for new U.S. wind capacity additions in 2015, with 1,042 MW completed. Steelcase and Apex are member and sponsor, respectively, of RMI’s Business Renewables Center (BRC). With its members, BRC is streamlining and accelerating large-scale corporate renewable energy purchasing.
