Rate Design for Electric Vehicles in California
California’s ambitious state law SB 350 aims to increase renewable energy generation and achieve “widespread transportation electrification” across the state. Pursuant to this law, California’s largest investor-owned utilities are proposing to make over $1 billion in transportation electrification investments. These investments are accompanied by new rate designs to support adoption of electric vehicles (EVs) and encourage charging in a manner that is consistent with electrical grid conditions. Synapse was retained by NRDC to evaluate the utilities’ rate design proposals for public fast-charging facilities, commercial fleets, and residential customers.
