In June 2026, the Indiana Utility Regulatory Commission approved a $71 million rate increase for AES Indiana. The decision affects more than 500,000 customers currently served by the utility in Indianapolis.
Why it matters
The Indiana Utility Regulatory Commission opted to revisit the case following direct criticism from Governor Mike Braun. This reconsideration process remains active, leaving the final structure of the utility rates and potential customer refunds uncertain.
The approved $71 million rate increase reflects a 3-1 commission vote. AES Indiana serves over 500,000 customers, with the first phase adding less than $1 monthly and the second phase estimated at $8.50 per month for 1,000 kilowatt-hour users.

Market Landscape
This regulatory move reflects the broader tension between utility infrastructure investment and consumer affordability in the state. It highlights how political oversight can shift the competitive environment for major providers like AES Indiana.
Most Indianapolis residents will see their monthly utility bills increase by approximately $8.50 starting in January 2027. If the rehearing process results in an overturned order, customers may be eligible for financial refunds.
