DTE Energy is issuing a Request for Proposal (RFP) for new standalone energy storage projects totaling approximately 120 MW.

These projects will support DTE Electric’s CleanVision Integrated Resource Plan and Michigan’s new standard of 60% renewable energy by 2030, both of which contribute to DTE’s overarching carbon reduction goals.

The RFP requires the energy storage projects to achieve commercial operation by March 31, 2027. Projects must be located in Michigan and interconnected to the Midcontinent Independent System Operator (MISO) or distribution-level transmission.

DTE currently owns and operates three energy storage facilities in Michigan, including the Ludington Pumped Storage Plant, a hydroelectric plant and long-duration storage facility on the shores of Lake Michigan co-owned with Consumers Energy; and two battery storage facilities located at solar energy sites.

Additionally, DTE’s Slocum Battery Energy Storage System, a 14 MW lithium-ion battery facility pilot in Trenton, Michigan, is expected to be operational in January 2025. The Michigan Public Service Commission also recently approved DTE’s plans for a 220-MW energy storage project at the site of the former Trenton Channel Power Plant.

By 2042, DTE plans to have 2,950 MW of energy storage capacity in its portfolio, more than doubling the amount the company has today.
