This is a proposed decrease, not an increase; I&M says new large industrial and data center customers are helping pay for the grid, letting it lower rates for everyone else, but the case still needs IURC approval.

After Amazon Web Services announced an 11 billion dollar data center campus near New Carlisle, Indiana, Indiana Michigan Power reached a settlement with AWS, Microsoft, Google, the state consumer counselor and the Data Center Coalition on how large new customers pay for the grid upgrades they require. The Indiana Utility Regulatory Commission approved the deal on February 20, 2025. It requires a 12 year minimum contract, requires large customers to pay for at least 80 percent of their reserved capacity whether they use it or not, and sets an exit fee that can exceed 1 billion dollars for a 1 gigawatt customer that leaves early.
What it means for your bill: This deal is meant to keep the cost of new substations and transmission lines for AWS's data centers off the bills of regular I&M customers by making the data center pay for capacity it reserves, not just power it actually uses.
