What are on-peak hours?

On-peak is defined as the hours during the day when electricity is most used and more expensive.

GCEA's on-peak hours occur from 5pm to 10pm Monday through Saturday.

How to cut down on energy during the on-peak hours:

- Adjust your thermostat
   - Consider investing in a programmable thermostat
   - Program your thermostat to come on early enough to have your home warm by 5 pm

- Limit hot water use
   - Consider placing a timer on your water heater that will help shift energy load

- Use high-wattage appliances before or after the on-peak hours
   - Dryer​
   - Washer
   - Oven
      - Use a toaster oven instead
   - Stove top
   - use the delay on dishwasher
