Hot weather can bring higher usage

AES Ohio prepares customers with ways to save during the summer months

May 7, 2025

Dayton, OH –  AES Ohio, a subsidiary of The AES Corporation (NYSE: AES), is helping customers to understand the reasons why bills are higher in hot weather and how their home uses energy. Planning ahead, tracking energy use and finding ways to reduce costs can help you manage your energy usage during the high heat months.

Over the past two years, the summer season in West Central Ohio has consistently recorded high temperatures, with several consecutive days reaching and exceeding 90°F and heat index values ranging from 100-110°F during the day. The hottest year on record was 2023 according to the Dayton Daily News.   

AES Ohio is considered a summer-peaking utility in Ohio. This means electricity demand typically peaks (2:00 PM to 6:00 PM) during the summer months due to increased usage of air conditioning and other energy-intensive devices.

Understanding home energy usage 

  • Heating and cooling account for over half your home’s energy usage. 
  • The number of days in each billing cycle can vary causing higher usage if there are more days.  

  • Wait until later in the evening to use heat-producing appliances, like the oven, clothes dryer and dishwasher. Many dryers and dishwashers have timers you can set so they turn on hours later. 

AES Ohio is committed to helping customers take control of their energy use and save money by following these hot weather energy efficiency tips: 

  • Help reduce cooling costs. Set your thermostat back at least 8 degrees each day - when you are at work and when you go to bed. Check out the AES Ohio Marketplace for more information and rebates on smart thermostats.
  • Don't set the thermostat lower than you want it, even if you're trying to cool your home quickly. It won't cool your home any faster, and it runs your system longer than necessary.
  • When using a ceiling fan, you an raise the thermostat setting a few degrees and still be comfortable. 
  • Shade south and west-facing windows during the hottest part of the day.
