On July 26, 2022, San Diego Gasoline & Electrical (SDG&E) introduced that it had efficiently deployed an progressive know-how that permits eight electrical college buses to place electrical energy again on the grid when wanted reminiscent of on sizzling summer season days. A collaborative effort between SDG&E, the Cajon Valley Union College District and regionally based mostly Cleantech San Diego firm Nuvve, that is the primary vehicle-to-grid (V2G) undertaking to grow to be operational in Southern California, serving to to advance clear air and local weather objectives whereas additionally bolstering grid reliability.


That is additionally the primary V2G undertaking to return on-line within the nation, following the U.S. Division of Power’s (DOE) vehicle-to-everything (V2X) initiative announcement in Los Angeles in April. SDG&E, which began on the undertaking previous to the announcement, is a signatory to the division’s V2X memorandum of understanding (MOU). The settlement is designed to deliver collectively assets from DOE Nationwide Labs, state and native governments, utilities, and personal entities to unlock the potential of bi-directional charging to extend power safety, neighborhood resilience, and financial progress whereas supporting the nation’s electrical system.


As a part of the five-year pilot undertaking, SDG&E put in six 60kW bi-directional DC quick chargers at Cajon Valley’s bus yard in El Cajon. The pilot was celebrated at an occasion on July 26 with undertaking companions and San Diego County District Two Supervisor Joel Anderson.


“This pilot undertaking is a good instance of our area being on the forefront of testing and adopting progressive applied sciences to cut back greenhouse gasoline emissions and strengthen the electrical grid,” SDG&E Vice President of Power Innovation Miguel Romero mentioned. “Electrical fleets characterize an unlimited untapped power storage useful resource and maintain immense potential to learn our clients and neighborhood not simply environmentally, but in addition financially and economically.”


On common, automobiles are parked 95% of the time. California is house to 1.1 million EVs, the biggest focus of EVs within the nation. Beginning in 2035, all new automobiles and passenger vehicles offered in California are required to be zero-emissions. Many native companies and native corporations are working to transition to electrical fleets beneath SDG&E’s Energy Your Drive for Fleets program, which offers infrastructure help. Along with Cajon Valley, SDG&E can be working with San Diego Unified and Ramona Unified College Districts on V2G initiatives.


“Pilots like these are vital to advancing trade information and commercialization of recent applied sciences that assist create jobs and construct a clear power future,” mentioned Workplace of Expertise Transitions Commercialization Govt Rima Oueid. “I’m thrilled to see this undertaking go reside lower than three months after the DOE launched our V2X initiative, validating the worth of public-private partnership.”


With the bi-directional chargers now in operation, Cajon Valley can take part in SDG&E’s new Emergency Load Discount Program (ELRP), which pays enterprise clients $2/kWh if they can export power to the grid or scale back power use throughout grid emergencies.


“We jumped on the alternative to be a part of this pilot undertaking due to its potential to assist us construct a more healthy neighborhood and higher serve our college students,” mentioned Assistant Superintendent Scott Buxbaum. “If we’re in a position to scale back our power and car upkeep prices on account of this undertaking, it frees up extra assets for our colleges and college students.”


V2G know-how works by permitting batteries onboard autos to cost up through the day when power, significantly renewable power reminiscent of photo voltaic is considerable. The batteries then discharge clear electrical energy again to the grid throughout peak hours or different durations of excessive demand.


“College buses are a wonderful use case for V2G,” mentioned Nuvve Co-Founder, Chair and CEO Gregory Poilasne. “They maintain bigger batteries than customary autos and may spend peak photo voltaic hours parked and plugged into bi-directional chargers. Nuvve’s know-how permits the grid to attract power from a bus when it’s wanted most, but nonetheless making certain the bus has sufficient saved energy to function when wanted.”


This V2G undertaking is a part of SDG&E’s intensive portfolio of unpolluted transportation and fleet electrification initiatives. To be taught extra about SDG&E’s Energy Your Drive for Fleet applications, please go to
