Michigan Attorney General Dana Nessel has urged the Michigan Public Service Commission (MPSC) to reduce DTE's proposed $237.5 million natural gas rate hike by 85%, potentially saving ratepayers tens of millions of dollars.

What changed
Michigan Attorney General Dana Nessel has filed testimony with the Michigan Public Service Commission (MPSC) opposing DTE's request for an 85% natural gas rate hike, which amounts to $237.5 million. The AG's office is advocating for a significantly reduced increase of $34.8 million, arguing that 85% of DTE's proposed expenditures are not justified by improvements in reliability, affordability, or customer benefit. This action is part of the AG's ongoing efforts to protect Michigan ratepayers from what she describes as "bloated, unjustified costs" and excessive expenses, including past instances of executive travel being passed on to customers.
Compliance officers should monitor the MPSC's decision in this case, as it will impact DTE gas customers in Michigan. The AG's intervention highlights the scrutiny applied to utility rate hike requests, particularly concerning the justification of expenditures and the prioritization of customer affordability. While this specific filing is an advocacy action by the AG, the MPSC's final determination will set the new rates and may influence future rate-setting proceedings for DTE and other utilities in the state. No specific compliance deadline is mentioned for regulated entities, as this is an advocacy action within an ongoing regulatory proceeding.
What to do next
- Monitor MPSC decision on DTE rate hike request
- Review AG Nessel's filed testimony for arguments against DTE expenditures

AG Nessel Seeks to Slash DTE Rate Hike by 85%
March 20, 2026
LANSING – Michigan Attorney General Dana Nessel has filed testimony in DTE’s latest natural gas rate hike case, urging an 85% reduction that could save Michigan ratepayers tens of millions of dollars. DTE filed its $237.5 million rate hike request with the Michigan Public Service Commission (MPSC) in November 2025, seeking to hike rates by an overall 10% increase for DTE gas customers, including at least an 8% hike for residential customers. This request follows DTE’s November 2024 natural gas rate hike of $113 million, less than half of what DTE initially sought after Attorney General Nessel intervened to protect Michigan ratepayers.
Attorney General Nessel sponsored testimony from four separate industry experts across multiple specialties on March 13 imploring the MPSC to limit the increase to $34.8 million. The recommendation prioritizes overall affordability for customers, fleet electrification studies, and payment options for low-income and vulnerable customers. The Attorney General found 85% of DTE’s proposed expenditures, for which it requests permission to bill its ratepaying customers, were not supported in its application as improving reliability, affordability, or providing meaningful customer benefit.
“DTE is raking in record profits while turning around and asking Michigan families to foot the bill for bloated, unjustified costs,” said Attorney General Nessel. “As no surprise, DTE has once again fattened its rate hike request with excessive and unwarranted expenses – this time by 85%. I implore the MPSC to stand up for Michigan ratepayers, prioritize affordability for customers, and not rubber-stamp the demands of utility corporations.”
Since taking office, the Attorney General has helped save Michigan consumers more than $4.1 billion by intervening in utility cases before the MPSC. Recent rate hike requests from DTE and Consumers Energy have included such inappropriate costs as private jet travel for executive staff and other unsupported expenditures that could not be demonstrated to be reasonable or prudent. Rate hike cases currently open before the MPSC include Consumers Energy’s electric rate hike request (U-21870) and a natural gas rate hike request (U-21981), SEMCO Energy Gas Company’s gas rate hike request (U-22002), Michigan Gas Utilities Corporation’s gas rate hike request (U-22007), and Upper Peninsula Power Company’s electric rate hike request (U-22032). DTE has also submitted a filing announcement, announcing its intent to file another electric rate hike in April.
DTE sells natural gas to 1.3 million customers across the state and electricity to approximately 2.2 million customers in Southeast Michigan.
