Google and DTE Energy to develop new data center in Michigan

DTE Energy has signed its first hyperscaler agreement to serve a 1.4 gigawatt (GW) data center, marking a 25% increase in its electric load and signaling significant growth potential in Michigan's data center sector. The utility's broader pipeline includes up to 7 GW of additional large-load projects, with total data center demand reaching 8.4 GW. DTE plans to invest $30 billion in generation, distribution, and infrastructure from 2026 to 2030 to support this growth, including $2 billion in energy storage solutions.

The agreement includes a 19-year power supply contract with minimum monthly charges and a 15-year energy storage arrangement, designed to ensure affordability for existing customers by selling excess capacity. However, experts caution that Michigan's aging grid, flat energy demand, and lengthy interconnection processes pose challenges to scaling this infrastructure. Additionally, local opposition remains a risk, as seen in Ypsilanti, where the city council is considering a data center moratorium despite no active proposals.

While Indiana Michigan Power has leveraged data center revenue to propose rate reductions for Indiana customers, similar benefits for Michigan residents remain uncertain. Ratepayer advocates warn that without safeguards, data center growth could shift costs to existing customers. Meanwhile, grid stability concerns persist, as sudden data center disconnections—like those in Virginia—could strain regional power systems. DTE's updated Integrated Resource Plan, expected in 2026, will outline how it intends to balance these challenges while expanding renewable and gas generation to meet rising demand.
