Indiana Michigan Power (I&M) has proposed a EUR 51 million rate cut for residential customers in Indiana, driven largely by rising revenue from data centers and other large industrial users. The utility, which serves more than half a million residential customers across Indiana and Michigan, describes the effort as one of the nation’s largest base rate reduction plans.
Under the proposal, Hoosiers would collectively save roughly EUR 51 million on electric bills by 2027. For a typical household using about 1,000 kWh per month, that amounts to approximately EUR 86 in annual savings. I&M also wants to freeze rates for the next three years, giving customers a measure of stability at a time when data centers are projected to consume 20% of U.S. power by 2035.
How the rate cut would work
The plan remains under review by the Indiana Utility Regulatory Commission (IURC), with a decision expected by June 2027. If approved, residents would begin seeing savings by the summer of that year. This would not be the first round of relief in the state: I&M already reduced its rates twice during the first half of 2026, easing pressure from rising electricity costs tied to surging AI demand.
PJM Interconnection, which operates the grid I&M relies on, has implemented price increases of up to 76% that it has described as irreversible. Even so, I&M says it has been able to shield its ratepayers from those higher costs. The utility credits load growth that lets it recover capital investments on grid upgrades more quickly, along with increased revenue from heavy consumption by large customers such as data centers.
“As Indiana continues to experience unprecedented growth, we are taking action to help our customers benefit from that growth through lower costs, enhanced value and continued investments to strengthen our system,” said I&M president and chief operating officer Maryam S. Brown. She added that the company is joining state leaders to advance economic development and make energy more affordable while maintaining reliability upgrades.
Other states following the trend
Indiana is not alone in passing savings to residential users as large customers shoulder more of the load. Oregon approved a 1.3% reduction in residential electricity prices in early July, while customers drawing 20 MW or more saw a 30% increase in their utility bills. Virginia, home to a large concentration of data centers, is following a similar path, with regulators requiring companies to pay for the dedicated upstream electrical infrastructure built to serve their operations.
These measures could help some Americans see slightly lower bills and address a common concern raised when a new data center is proposed nearby. Even so, other issues tied to these projects remain, including impacts on water supply and noise pollution, which continue to fuel community resistance to new developments.
