This study investigates the demand response (DR) capability and potential of a controller which can lower the speed of variable speed pool pumps. The vast majority of incumbent pool pumps are single speed and can only be turned off for DR measures. Variable speed pool pumps have the ability to lower the pumping speed during DR events while maintaining minimum filtration rates and eliminating the risks of power cycling and health safety concerns. The target customers for this technology are single family residences (SFR); multi-family residences and public pools have regulations that limit DR measure effectiveness. According to appliance and census surveys, there are about 109,915 SFR pools in SDG&E territory and 1,094,939 California-wide. Previous study has found that virtually all these pumps are single speed and that the total SDG&E pool pump daily energy consumption is about 776 MWh. Replacing these single speed pumps with high-efficiency variable speed models and a DR-enabling controller could prove to be a significant energy savings and demand reduction opportunity.
