Electric Thermal Storage

Electric Thermal Storage (ETS)


What’s Electric Thermal Storage?

Electric thermal storage, or ETS, is an electric home heating device containing ceramic bricks that can help lower your heating costs by storing heat when electricity costs less, and then releasing the heat throughout the day.

Our time-of-day (TOD) rates are what makes an ETS cost-efficient. TOD rates change depending on the overall power demand. During off-peak times—overnight, on weekends, and holidays—the demand for power is lower, resulting in a lower billable rate.
