Powering a reliable, affordable, and sustainable energy future
AES Indiana filed a Regulatory Rate Review with the Indiana Utility Regulatory Commission (IURC) on June 3, 2025. AES Indiana is committed to making investments that will support Central Indiana and the customers we serve with cost-effective and reliable electric service now and well into the future.
Why AES Indiana is requesting a rate review
Rising costs
Like many industries, AES Indiana is facing higher costs for materials, labor, and services due to inflation and market conditions. These increases impact core areas like trimming trees away from our power lines and storm restoration.
Grid resiliency and reliability
We're making strategic investments to modernize the grid and make it more reliable by strengthening infrastructure and implementing new technology - especially in response to more frequent and severe storms.
Sustainability
AES Indiana continues to deliver on our decade-long energy transition, including generation investments such as natural gas, wind, solar, and battery storage.
What to expect: timeline and impact
If approved, AES Indiana's rate request will be implemented in two phases:
- Phase 1 - Q1 2026: Estimated increase of up to $12 or 7.5% for a residential customer using 1,000 kWh per month.
- Phase 2 - January 2027: Estimated increase of op to $9 or 6% for a residential customer using 1,000 kWh per month.
- Total estimated increase by January 2027: Up to $21 per month or 13.5% as compared to what bills would otherwise be at the time.
How do I plan for this change?
Customers can use the AES Indiana Bill Calculator to estimate how the proposed rates may impact your household based on energy usage.

How this rate change affects your bill
Enter the number of kilowatt-hours (kWh) usage from your most recent bill in the field below to estimate your monthly increase. (A kilowatt-hour is the unit of measurement for the amount of electricity used in a household. One kilowatt-hour is comparable to ten hours of TV-watching, or vacuuming for one hour.)
Please have your AES Indiana bill in front of you or log into your AES Indiana account to look at your most recent bill.
Step 1
What is your rate code?
Whether you receive a paper bill or pay online, your rate code is listed as a line item on your bill under the section called “Metered Electric and Other Services.” It appears under the label “Rate.” Common rate codes are 2- or 3- letter abbreviations, for example “RS.”
Step 2
What is your monthly kWh usage?
Whether you receive a paper bill or pay online, your monthly kilowatt-hours (kWh) usage is listed as a line item on your bill under the section called “Meter Reading Detail.” It is most commonly a 3- or 4-digit number (example: 1232) and it appears under the label, “Usage.” Use your most recent bill to get the most accurate increase estimate.

* Your estimated monthly increase total is only an estimate; the Indiana Utility Regulatory Commission is in the process of reviewing the rate increase request and the final increase amount has not been determined. This estimate includes the “kWh Usage” figure only; taxes are excluded. Please note that rates will be implemented in two phases, and the estimated monthly increase represents the cumulative increase a customer may experience as a result of both phases. Please note that this tool compares estimated future bill amounts using the rates proposed by the Company in its rate review with Adjusted Test Year base and tracker revenues at present rates.

Your questions answered
We’re aligning rates with the increased cost of providing electric service – including grid maintenance, infrastructure improvements, and the transition to cleaner energy sources. These changes help ensure reliable, resilient service while preparing for future energy needs.
Yes. AES Indiana has consistently offered some of the lowest residential rates among Indiana investor-owned utilities and remains committed to affordability. Even with new rates implemented, AES Indiana anticipated remaining among the lowest rates among investor-owned utilities in Indiana.
Our energy efficiency programs are available year-round and help customers understand and control their energy usage. Learn more here.
We’ve made significant investments to strengthen infrastructure, speed up storm recovery, and avoid outages. For example:
-
During our most recent Level III storm on April 2, 2025, our upgrades helped avoid 39,400 customer outages.
-
During Hurricane Helene in 2024, we avoided close to 30,000 additional outages through smart grid technologies.
Vegetation, like overgrown trees, is the leading cause of outages accounting for approximately 30% of service interruptions. Rising costs and expanded tree trimming programs are necessary to protect reliability.
We understand customers count on us to keep costs as low as possible and increasing bills can be a financial challenge for our customers. For more information, visit aesindiana.com/payment-assistance.
