Residential Demand-Response Spinning Reserve Demonstrations at PG&E and SCE

Project Status: 

This project conducted first-ever demonstrations of the use of large fleets of residential load management technologies (radio-dispatched switches on central air conditioning units) to provide spinning reserves that met the operational dispatch requirements of the California ISO. Separate demonstrations were conducted with the Southern California Edison and Pacific Gas and Electric Companies, each using a different load management dispatch platform and 1000’s of air conditioning load control technologies. The demonstrations provided real-time visibility of aggregated load curtailments to system operators at the California ISO and explored a variety of technologies and methods for verifying aggregate performance following each dispatch event.
