Why does my power bill rise with the summer heat?

Summer outside

You’re probably used to receiving a higher bill during the hot months. But there are still ways you can save energy even as the temperature rises. Here are two reasons for that higher bill, along with a few of our favorite ways to help keep it from climbing.


It can be difficult to keep your home at a comfortable temperature during the dog days of summer. Even if you keep your thermostat at the recommended 78 degrees in the summer, when it is 95 degrees outside your air conditioner must run longer than when it is 80 degrees outside. This leads to a higher energy bill.

Closing curtains and blinds can help your home stay cool by blocking sunlight from warming rooms in your home. Also, installing a smart thermostat that can automatically schedule your air conditioner to run before you arrive home instead of cooling your home all day will help you save energy and money. Plus, our smart thermostat savings program offers a $50 rebate when you join with your Nest or Ecobee! Learn more at pemc.coop/thermostat.

Energy use changes

For many families, summer signals the end of the school year and the beginning of pool time.

You might see a spike in your energy use if your kids are home during the day in the summer. The hours of video games and countless searches for snacks in the fridge can add up to a noticeable difference on your power bill. Encourage your family to unplug all appliances when not in use and to limit their time with the fridge door open to conserve energy.

Home pools can also contribute to a higher energy bill in the summer. Consider upgrading your pool pump to an energy-efficient, variable speed version and clean the filter regularly.
