Ford’s retooled Michigan Assembly Plant in the city of Wayne is home to one of the largest solar arrays in Michigan. Detroit Edison, Xtreme Power, Inovateus Solar, Nova Consultants, and the state teamed up with Ford to install a 500-KW solar array along with a 750-KW battery system with 2 megawatt-hours of energy–enough to power 100 average homes in Michigan for a year.
