A proposed rate increase from Indiana Michigan Power is getting pushback from Michigan Attorney General Dana Nessel. Her office says Nessel last week filed a notice of intervention as I&M seeks to raise electric rates by 18.9% in order to generate $58.5 million. I&M filed a request for the rate increase with the Michigan Public Service Commission after announcing its plans last month. Nessel issued a statement Wednesday, saying “On the heels of a 20-percent rate increase for customers just last year, I&M has no business looking for another exorbitant rate hike on the backs of our residents. This increase is simply unsupportable and unreasonable on its face.” Nessel is also intervening, or planning to intervene, in rate increase attempts being made by Consumers Energy, SEMCO, and DTE Electric Company.
