DTE Energy announced it will refrain from filing any new electric rate increase requests until at least 2028, provided its first data center project is operational by the end of 2027 and remaining approvals are secured. This two-year moratorium follows the company’s planned rate case submission to the Michigan Public Service Commission on April 28, 2026.

The company’s two data center contracts—one approved in Saline Township and another under review in Van Buren Township—are projected to contribute nearly $9 billion toward grid improvements through 2045. By spreading fixed costs across large new customers, DTE aims to lower per-customer bills and support ongoing investments without burdening existing ratepayers.

The April 28 rate case will formally request $474.3 million for grid and generation enhancements, kick-starting a roughly 10-month regulatory review process. A final decision by the commission is expected in late February 2027, with any approved rate changes implemented soon after.

DTE’s 2025 electric reliability performance was its best in nearly 20 years, cutting customer outage time by 60% versus 2024. The filing also underpins projects like the Belle River plant conversion to natural gas and the Trenton Channel battery storage facility, reinforcing cleaner energy goals while aiming to keep future bill growth among the nation’s lowest.
