PG&E Electric Vehicle Automated Demand Response Study Report

The study, conducted on behalf of Pacific, Gas and Electric Company (PG&E), analyzed data of EV consumers to quantify the peak and overnight load management potential for EV charging control technologies. This data revealed that EV charging load is greatest overnight, and EV charging controls hold promise for mitigating EV overnight peaks. Opinion Dynamics also verified the EV load management capabilities of vendors that control chargers directly (ChargePoint® and Enel X®) as well as vendors that leverage vehicle telematics (Geotab Energy®) with a sample of PG&E EV owners through a technology field test. The field test results revealed that all vendors effectively curtailed EV charging during demand response (DR) events with minimal impact on the study participants.
