DTE Energy is looking for proposals for 1 gigawatt of renewable power projects in Michigan, a new round of wind and solar development that could shape how the utility adds clean electricity over the next several years. The company said the projects must be completed by Dec. 31, 2029, and connect either to the Midcontinent Independent System Operator or to the DTE distribution system.

The schedule is already set. DTE will hold a pre-request for proposal conference on May 26, project bids are due on Aug. 13, and contracts are expected to be executed in early 2027. The utility said the projects will support DTE Electric’s Clean Vision Integrated Resource Plan, the roadmap behind its long-term power mix.

The scale matters because DTE’s current renewable output already powers more than 900,000 homes. The company wants that to reach 6 million households by 2042, a target that depends on building far more wind and solar capacity than it has today.

That makes this solicitation more than a routine procurement. It is a direct test of how quickly DTE can turn planning goals into steel, panels and turbines on the ground, while still meeting the interconnection and completion deadline it has set for the end of 2029.

The pressure is on the timeline as well as the supply chain. Bidders will have to line up projects that can clear the planning, financing and grid-connection hurdles in time for early 2027 contracts, then move fast enough to bring the projects online before the end-2029 cutoff. For Michigan, the result could add a large block of new renewable power to a grid that is already being asked to do more in every direction.
