Your AES bill has three basic parts. The base rate makes up most of your bill and is like a self-serve frozen yogurt place – you pay based on how much you use. The base rate requires approval from the Indiana Utility Regulatory Commission to change. Sales tax is added to your total, which is 7% of your bill.
Trackers
Trackers are smaller charges that make up a lower percentage of your bill than the base rate. AES has seven trackers, which can change up to four times every year. Trackers are charges that companies use to recover some costs outside of the base rate. For example, AES customers are likely seeing more expensive bills this summer because of an increase to the fuel adjustment charge.
To stay on top of exactly how and why your bill is changing, you can look at a yearly survey from the regulatory commission. The survey shows how much each company charges based on how much energy is used, and you can also find a list of trackers and their prices.
The regulatory commission’s case portal is the most comprehensive resource for keeping track of what a utility company is doing. You can search for a specific cause number or company to find the information you need.
