A invoice presently making its method by way of the California legislature would require all new EVs bought within the state to be outfitted with bidirectional charging functionality by 2027. SB 233, which has handed the Senate Vitality Committee and might be heard earlier than the Senate Transportation Committee on April 25, would additionally set up state objectives for bidirectional charging, enhance funding for bidirectional infrastructure, and promote interoperability testing.
“EVs are power storage on wheels. Why waste that battery, given how few miles most individuals use the automobile in any given day?” stated the invoice’s sponsor, State Senator Nancy Skinner (D-Berkeley). “However we have to make it as straightforward as doable.”
By most accounts, a 60 kWh EV battery may present backup energy to a median US family for at the least two to 3 days. Such a V2H characteristic may very well be extremely helpful in California, the place residents face a rising risk of rolling blackouts during times of peak demand.
California’s vehicles could have 60,000 megawatts of saved power in batteries by 2030, Siva Gunda of the California Vitality Fee advised GovTech. If simply 10% of that may very well be returned to the grid, “we are able to get by way of what we went by way of final yr with out turning on the backup turbines.”
Utility PG&E says it’s making ready the grid for the bidirectional future, however warns that the state isn’t prepared for rapid widespread adoption. “It represents a brand new path. We wish to lead the nation in reliability, resiliency and lowered emissions,” stated Aaron August, VP of PG&E’s Utility Partnerships and Innovation, including that requirements to assist V2X functions at the moment are in improvement.
Gregory Poilasne, the CEO of bidirectional charging pioneer Nuvve, lately testified earlier than the California Senate Vitality, Utilities and Communications Committee in assist of the proposed laws. “California should strategy V2G the identical method it has handled rooftop photo voltaic or EV adoption—with objectives, incentives and fostering stakeholder collaboration,” he advised lawmakers. “SB 233 does all three, and can assist rework right this moment’s kilowatts and megawatts of cell grid storage into tomorrow’s gigawatts.”
