Permanent Load Shifting

Earn an incentive to help offset the initial investment in a mature Thermal Energy Storage system. By storing energy that is produced for cooling when energy costs are lower (off-peak), and then distributing that stored, cooled air during on-peak periods, you can save money on your bill.

SDG&E’s Permanent Load Shifting program requires you to shift energy use for cooling during the summer peak hours to off-peak hours. These incentives are open to all SDG&E customers. To be eligible you must:

  • Be on a Time-of-Use (TOU) rate
  • Have an SDG&E smart meter or an approved interval meter
