LANSING, Mich. (Michigan News Source) – Michigan Attorney General Dana Nessel continues her role as a watchdog over DTE Electric.

Nessel’s office sent a press release claiming DTE has approved more than $1 billion in annual revenue increases since 2020 “despite continued reliability and affordability concerns.”

Nessel was prompted after DTE received approval Feb. 19 from the Michigan Public Service Commission for a $242.4 million rate increase, although it asked for a $574 million rate hike.

According to the most recent data from the U.S. Energy Information Administration, Michigan has the highest residential cost for electricity in the five-state East North Central region that includes Illinois, Indiana, Ohio and Wisconsin.

DTE is an electronic company that serves 2.3 million customers in Southeast Michigan and a natural gas company that serves 1.3 million customers in Michigan.

DTE said the rate increases will pay for infrastructure improvements.

“It will help support continued, targeted investments that are improving electric reliability and strengthening the grid across Southeast Michigan – reducing outages, speeding restoration and making the system more resilient in all weather conditions,” DTE said in a press release. “These investments are delivering real results: there was a 60% reduction in the time spent without power in 2025 – on top of the nearly 70% reduction achieved in 2024, with significantly fewer power interruptions and faster restoration when outages do occur.”
