DETROIT, Apr. 22, 2026 – DTE Energy (NYSE:DTE) today announced the company is issuing a Request for Proposal (RFP) for new standalone energy storage projects totaling up to 480 megawatts.
The RFP requires the standalone energy storage projects to achieve commercial operation by Q1 2029. 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 4, 2026. Bids are due by July 8, 2026, and DTE expects to execute contracts by Q1 2027.
The new projects will be key assets within DTE’s growing energy storage portfolio, which includes the 14-megawatt Slocum Battery Energy Storage System and the 220-megawatt Trenton Channel Energy Center, both located in Trenton, Michigan. When complete later this year, the Trenton Channel Energy Center is expected to be the largest standalone battery energy storage facility in the Great Lakes region.
