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.

What it means for your bill
$
AES Indiana originally sought a 192.9 million dollar rate increase. After a settlement with industrial customers, Walmart and the City of Indianapolis, the IURC voted 3 to 1 on June 17, 2026 to approve a smaller 71 million dollar increase, an overall bill impact of about 3.7 percent phased in over two steps in July 2026 and January 2027. For a typical residential customer using 1000 kWh a month, each phase adds less than 5 dollars. The state consumer counselor and a citizens group asked the IURC to reconsider the decision in July 2026.
