The Michigan Public Service Commission gave formal approval to power agreements between DTE Energy and Google on Oct 1, 2026, allowing the utility to move forward with the special supply arrangements for the planned data centre campus.

Under a 20‑year Primary Supply Agreement and a Clean Capacity Accelerator Agreement, Google will receive up to 1 GW of electricity, with the facility expected to start drawing power in Dec 2027 and reach its full contracted load by Dec 2028.

The data centre will occupy roughly 282 acres near Haggerty Road and I‑94, comprising nearly 1.5 million sq ft of building space.

DTE will provide the site with service under its Rate D11, a tariff designed for large‑scale electricity customers, and the contract requires Google to maintain a minimum billing demand equal to 80 % of the 1 GW capacity.

If Google terminates the agreement early, the contract includes cost‑recovery provisions to protect DTE’s existing customer base.

A new 345‑kV switching station and two high‑voltage transmission feeds, being built by ITC Transmission, will connect the campus to the Brownstown‑Wayne 345‑kV lines.

The first transmission feed is slated for service in late 2027, with the second feed following in late 2028; construction of the switching station is set to begin in Q1 2028 and finish by Q3 2028.

Google will fund up to 1,600 MW of renewable generation and 480 MW of battery storage as part of the agreement, linking its demand to new clean‑energy resources.

DTE’s resource planning must now account for the additional data‑centre load, ensuring the utility’s system can accommodate the new demand.

The MPSC approval clears a major state‑level hurdle, but the project still requires local township planning approvals and other development steps before construction can commence.
