AI summary The text discusses differences in snapback effects for various space heating equipment, particularly heat pumps, during curtailment events. It explains that heat pumps may experience more pronounced snapback due to the activation of heat strips when the compressor is unable to operate at lower temperatures. However, the overall impact may be mitigated due to the short duration of the snapback effect and potential use of supplemental fuels.
In situations where customers might use gas and other supplemental fuels for heating, snapback effect could be mitigated by some of the other fuel types being used for heating during the event period. For water heating load control, some p...
AI summary The text discusses the snapback effect in demand response (DR) programs, particularly for water heating load control.
