DTE Energy in Detroit today announced the company is issuing a Request for Proposal (RFP) for new standalone energy storage projects totaling approximately 120 megawatts.
The projects will support DTE Electric’s CleanVision Integrated Resource Plan and Michigan’s new standard of 60 percent renewable energy by 2030, both of which will contribute to DTE’s overarching carbon reduction goals.
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-megawatt lithium-ion battery facility pilot in Trenton, is expected to be operational in January 2025. The Michigan Public Service Commission also recently approved DTE’s plans for a 220-megawatt energy storage project at the site of the former Trenton Channel Power Plant.
The RFP requires the standalone 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 or distribution-level transmission.
Interested bidders should register their company information on the PowerAdvocate website and, once registered, can attend a virtual pre-RFP conference on May 23. Bids are due by August 2 and DTE expects to execute contracts by Q1 2025.
“Energy storage facilities are imperative to Michigan’s clean energy transformation and a great complement to DTE’s growing renewable energy generation fleet,” says Chuck Conlen, vice president, clean energy and acquisitions, at DTE Energy. “DTE is proud to be a leader in the energy storage space as we continue developing a balanced energy fuel mix that delivers cleaner, reliable, and affordable energy to our customers.”
By 2042, DTE plans to have 2,950 megawatts of energy storage capacity in its portfolio, more than doubling the amount the company has today.
DTE Energy includes an electric company serving 2.3 million customers in southeast Michigan and a natural gas company serving 1.3 million customers across Michigan.
The DTE portfolio also includes energy businesses focused on custom energy solutions, renewable energy generation, and energy marketing and trading.
