Water Heating

Control your water heater and save

We offer two ways to save on your water heating costs—a $4 monthly water heating credit with a simple low-cost connection process, or our discounted water heating controlled service rate for locations with a secondary meter and service panel. Both options let us control energy during peak periods while lowering your energy bill.

How it works

Water heating credit for standard general service

The water heating credit is a way to save money on your water heating costs without having to install a separate meter and service panel.

You’ll need to have an electrician connect your electric water heater to your existing general service meter and provide a wire for us to use to make a connection. Then, we’ll install a radio receiver at no additional cost.

During peak energy periods, we’ll signal the receiver to control energy to your water heater. Once the peak period has passed, it returns to normal operation. For participating in energy control, you’ll receive a $4 credit on your monthly bill.

Water heating controlled service rate

You’ll need to have an electrician connect your electric water heater to an off-peak electrical service panel and provide a wire for us to use to make a connection. Then, we’ll install a radio receiver at no additional cost.

During peak energy periods, we’ll signal your meter to control energy to your water heater. Once the peak period has passed, we'll restore normal service.

The water heating controlled service rate gives you greater cost savings on your water heating (you’ll save about 25% on your monthly bill, compared to our standard electric rates), while helping us reduce our energy load during peak periods.

For the greatest savings, you also can add an electric water heater to your heating service panel to take advantage of one of our other low off-peak rates, such as Deferred Load, Dual Fuel, or Residential Demand Control.

If you don’t currently have an electric water heater or are planning to replace your current system and would like to take advantage of off-peak savings, rebates are available.
