Background 

• Currently, California Green House Gas (GHG) rules pertain to Heat Pump Water Heaters (HPWH) and are silent on Grid-Interactive Electric Water Heaters (GIEWH)
• The Self-Generation Incentive Program (SGIP) excludes most types of thermal energy storage (TES) and is overseen by the California Public Utilities Commission (CPUC)
• There is no approved methodology for evaluating TES benefits in the SGIP program 
• The recent UC Davis report (https://wcec.ucdavis.edu/thermal-energy-storage-valuation/) indicates the benefits TES brings to the grid is undervalued by current DR measuring methods.
