LANSING, Mich. (Michigan News Source) – Attorney General Dana Nessel has filed a notice of intervention to contest proposed annual electric rate hike of $436 million by Consumers Energy.

If the rate hike is approved by the Michigan Public Service Commission, it would take effect in May 2026. Nessel said in a June 2 press release the rate hike was likely the largest in decades. The Michigan Public Service Commission approved a $154 million rate hike for Consumers Energy in March. That rate hike hit customers bills on April 4, 2025.
