Hoosiers frustrated by rising electric bills are increasingly looking for answers, as new reports suggest the state could see some of the steepest electricity price increases in the country in the coming years.

A recent analysis highlighted by consumer groups found Indiana’s electricity costs are projected to rise significantly, driven by a combination of infrastructure investments, power plant retirements and increased demand for electricity.

At the same time, a new online calculator launched by the Energy and Policy Institute estimates that a portion of Hoosiers’ monthly electric bills goes toward profits for the state’s investor-owned utilities.

According to the analysis, estimated profit margins embedded in residential bills range from roughly 4.5 percent for AES Indiana to nearly 20 percent for Northern Indiana Public Service Company (NIPSCO), with other utilities such as Duke Energy Indiana, Indiana Michigan Power and CenterPoint Energy falling somewhere in between.

Consumer and environmental groups say those numbers highlight the need for greater transparency and stronger protections for ratepayers.

Advocates argue that Hoosiers deserve a clearer understanding of how much of their monthly electric bill goes toward operating costs versus corporate profits.

But people familiar with Indiana’s energy industry say the rising costs are the result of several long-term trends affecting utilities across the country.

Sources say inflation, aging infrastructure and growing electricity demand are among the primary factors pushing electric rates higher.
