Residential smart-charging pilot program in Toronto: Results of a utility controlled charging pilot

Thirty plug-in electric vehicle (PEV) owners in Toronto participated in the 15-month Charge TO program, which actively curtailed their vehicles during charging. The intent was to demonstrate the technical feasibility of the smart-charging system and evaluate its limitations, quantify the real-world curtailment availability of the PEVs, and to capture the participant's impressions and response to various incentive structures. A key feature of this program was the use of vehicle-side data, namely battery state-of-charge (SOC), to ensure that charge curtailments did not negatively affect the participants. This paper summarizes the findings from the ChargeTO program.
