60 MW DTE Energy Solar Farm

Lapeer, Michigan

J. Ranck Electric was the prime contractor for what was, at the time of construction, the largest solar project in Michigan and largest utility-owned solar array east of the Mississippi River. Located in Lapeer, this system consists of two separate arrays owned and operated by southeast Michigan power supplier DTE Energy on land leased from the City of Lapeer. The arrays included over 188,000 solar panels on nearly 420 acres of land with portions visible to drivers on I-69. With crews exceeding 120 workers and a total of 160,000 man-hours worked with zero OSHA recordable incidents, JRE safely met the aggressive project schedule with completion in 2017. The solar farm will generate enough power for 9,000 homes.
