Indiana Michigan Power says Indiana customers will see lower electric bills beginning with the June 2026 billing cycle.

According to the utility, the average residential customer using 1,000 kilowatt hours of electricity each month will see bills drop by about 3.6%, or roughly $6 per month.

The decrease comes after the Indiana Utility Regulatory Commission approved I&M’s request to reduce a monthly charge tied to how the company manages and sells energy in the regional power market. The charge appears on customer bills as the “Off System Sales Margin Sharing/PJM Cost Rider.”

I&M says the lower charge is partly due to additional revenue expected from selling excess power in 2026. The company says those savings are passed along to customers through reduced rates.

The utility also pointed to broader efforts aimed at keeping energy costs affordable. Earlier this year, I&M announced plans to file a Customer Benefits Plan later this summer that would reduce base rates for Indiana customers and freeze non-fuel rates over multiple years.

Company officials say increased demand and revenue from large customers, including data centers, are helping support those plans.

As a regulated utility, Indiana Michigan Power must submit proposed rate changes and customer programs to the Indiana Utility Regulatory Commission for approval.
