Our residential Time-of-Use Opens pdf pricing plan offers an opportunity to reduce your monthly bill by shifting the majority of your electricity usage to off-peak hours.

How does Time-of-Use work?

Our Time-of-Use plan includes higher “on-peak” rates during periods when UES customers typically use the most power and lower “off-peak” rates the rest of the day. In this way, the plan rewards customers who shift their usage away from peak usage periods.

What are the potential advantages of this plan?

Customers on this plan have more control over their energy costs by choosing when they use electricity. Use most of your electricity during off-peak time periods, and you could significantly lower your monthly bill.

Time-of-use is designed to reward customers who do their part to reduce demand on the electric grid, particularly during peak usage periods. Reducing the peak energy demand promotes more efficient use of our energy resources and can help limit future rate increases.

What are the potential disadvantages of this plan?

If you use a lot of power during on-peak hours, your energy costs could increase under our Time-of-Use plan. Changes in your household’s energy habits may be necessary to achieve bill savings. The more you are able to shift your usage away from peak hours, the more you can save. Your savings will vary based on your usage patterns.

How can I shift my electric usage to off-peak time periods?

  • Operate washing machines, clothes dryers, dishwashers and other large appliances during off-peak hours.
  • Adjust your thermostat to reduce heating and cooling during on-peak hours or when you are not at home.
  • Install timers on electric water heaters and recirculation pumps so they operate mainly during off-peak hours.
  • Set timers on pool and spa pumps to run during off-peak hours.
  • Turn off all but essential lights during on-peak hours.
  • Enjoy electricity-consuming hobbies during the off-peak hours.
  • If you have an electric vehicle, charge it during off-peak hours.
