Time-of-use

Pre-cool before the peak

On many time-of-use plans, electricity costs most in the late afternoon and evening. Cooling the house a little earlier, then letting it drift a few degrees, can shift much of that use out of the peak.

Plan your schedule

  • Before the peak

    Cool a couple of degrees below your usual setting.

  • During the peak

    Let it drift up a few degrees; the house holds the cool.

  • After the peak

    Back to your normal setting for the evening.

FAQ

Questions

What is pre-cooling?

Cooling the house a couple of degrees below your usual setting before the peak rate period, then letting it drift up a few degrees during the peak. The house holds much of the cool.

Which hours are peak on my plan?

It depends on your plan and utility. Many time-of-use plans have a 4pm to 9pm peak; check your bill. Some Corona addresses are served by the city utility rather than SCE.

Will pre-cooling save me money?

It can shift cooling out of the most expensive hours, but results depend on your plan, your home and your habits. We do not promise a set saving.

Do you work on commercial buildings?

Yes. Warehouse offices, showrooms, retail, restaurants and offices, with rooftop units, controls and maintenance plans.
