PG&E's WatterSaver program, launched in March 2022, has generated a significant amount of data from participating heat pump water heaters (HPWH). SCE's SmartShift Rewards program, launched in May 2024, is building on the lessons learned from WatterSaver, with a strong equity focus. In this session, program implementers and utility representatives share lessons learned on connecting and controlling HPWHs from different manufacturers, outreach and engagement strategies for different target sectors, as well as the impact of customers' settings on load up strategy (Basic Load Up, BLU versus Advanced Load Up, ALU) and load shifting results, both from the utility and customer's perspective. Finally, we discuss progress needed to scale load shifting using thermal storage to meaningfully participate in the stabilization of the electric grid and the reduction of carbon emissions, in California and nationwide.
