Duke Energy Indiana Rate Request Update

On Jan. 29, 2025, the Indiana Utility Regulatory Commission (IURC) issued an order on Duke Energy’s rate request submitted on April 4, 2024. The order enables us to adjust base rates to continue making investments in a modernized electric grid that is more resistant to power outages, increasing reliability at our power plants, constructing hundreds of miles of new power lines, complying with evolving environmental responsibilities and improving electric grid security.

Duke Energy customers will see an overall average bill increase of approximately 11% that will be added to bills in two steps: approximately 8% on Feb. 27, 2025, and approximately 3% in early 2026.* The increase will vary among consumers depending on the cost to serve different types of customers, such as residential and business. The total monthly bill impact of the two steps for an average residential customer using 1,000 kilowatt-hours (kWh) a month is about 13%, or $18.76 a month.

Impacts by rate class

Some of the customer benefits that are part of this rate order include:

A stronger, more resilient electric grid

  • We have been installing state-of-the-art sensors on power lines that can automatically detect problems. Much like the GPS in a car that can identify an accident ahead and reroute a driver around the incident, the technology can quickly identify power outages and alternate energy pathways to restore service faster for customers when an outage occurs. For a video of how the technology works, visit our self-healing technology page.
  • We are continuing to harden our system against severe weather to reduce power outages, including changing wood poles to steel, undergrounding power lines in targeted, outage-prone areas and rebuilding miles of overhead power lines.
  • In the wake of physical attacks to the electric grid nationally, we are taking steps to improve physical security and protections at some of our key infrastructure delivering power to Indiana communities.

Powering a growing state

  • Our state’s economy is growing, with more than 60,000 new residential and business customers in our service territory. We are adding 345 miles of new power lines and additional infrastructure to serve them.

Environmental obligations driving cleaner operations

  • Federal rules require changes to the way we manage coal ash generated from electricity production and stored at our power plant sites. We are closing ash basins responsibly and in compliance with environmental regulations.

Providing customers with more convenience

  • We need to keep pace with evolving customer needs and expectations and have installed new systems, such as the ability for customers to initiate service at a new location online and receive service the same day.

New rate options

  • To help customers manage their electric bills, we are offering time-of-use rates where customers can shift some of their power use to times of day when energy is less expensive. This is a voluntary program for residential, commercial and industrial customers interested in participating.

*These rates are being implemented on a subject-to-refund basis, pending the outcome of a petition for reconsideration and rehearing before the IURC.
