Clock with text that reads Time of use is here!


TOU billing divides a consumer's electricity consumption into three different time periods; on-peak, mid-peak and off-peak. Each time period has a corresponding rate that will be charged for electricity used during that time. On-peak electricity rates are the highest, off-peak electricity rates are the lowest and mid-peak rates fall somewhere in between. While weekends and holidays are always off-peak, TOU periods for weekdays change seasonally.

Take a few minutes to look at the timing of your energy use at home or at your business. With TOU billing, small changes to daily routines can make a big impact. For example, running high-energy appliances like dishwashers, washing machines and dryers after 7 pm instead of earlier in the day shifts consumption from on-peak and mid-peak periods to an off-peak TOU period resulting in lower charges on your bill.

Time-of-Use Tips and Resources

Residential Customers

Make the shift. See if there are ways you can shift energy-intensive activities to off-peak hours to take advantage of TOU rates. Prices are lowest on weekdays between 7 pm and 7 am and all day on weekends and holidays.

Adopt some of these tips to help reduce or shift your energy consumption:

  • do some or all of your laundry on weekends or weekdays during mid-peak or off-peak times
  • wash in cold water and hang laundry out to dry when weather permits
  • set your dishwasher to run after 7 pm, always run full loads and use the eco-cycle if you have one
  • unplug battery chargers as soon as devices are fully charged or when the charger is not being used; this prevents the use of “phantom power”
  • avoid charging batteries during on-peak periods
  • plug large-screen TVs, DVD players, game consoles and computer equipment into a power bar and turn the power bar off when not in use
  • try using timers where possible to operate pool pumps, filters and heaters during off-peak periods
