How It Works

AC Saver was a voluntary demand response program available to residential customers with air conditioner (AC) units installed at their premise with SDG&E approved technology capable of curtailing the customers’ AC unit. After signing up for the AC Saver program, SDG&E would install a device on customer central air conditioning units at no cost. On select hot days, when conservation was needed, the installed device was activated to cycle your central air conditioner "on and off" for a period of two to four hours.

The program ran during the months of  April through October and activations could be called every day of the week, but only up to 25 events annually could be called with five events being reserved for emergency use only.
