On July 26, 2022, San Diego Fuel & Electrical (SDG&E) introduced that it had efficiently deployed an modern expertise that permits eight electrical faculty buses to place electrical energy again on the grid when wanted akin to on sizzling summer time days. A collaborative effort between SDG&E, the Cajon Valley Union College District and regionally primarily based Cleantech San Diego firm Nuvve, that is the primary vehicle-to-grid (V2G) mission to change into operational in Southern California, serving to to advance clear air and local weather targets whereas additionally bolstering grid reliability.


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


As a part of the five-year pilot mission, 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 mission companions and San Diego County District Two Supervisor Joel Anderson.


“This pilot mission is a superb instance of our area being on the forefront of testing and adopting modern applied sciences to scale back greenhouse fuel emissions and strengthen the electrical grid,” SDG&E Vice President of Vitality Innovation Miguel Romero stated. “Electrical fleets characterize an enormous untapped vitality storage useful resource and maintain immense potential to learn our clients and group 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 most important focus of EVs within the nation. Beginning in 2035, all new automobiles and passenger vans offered in California are required to be zero-emissions. Many native companies and native firms are working to transition to electrical fleets below 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 tasks.


“Pilots like these are crucial to advancing trade data and commercialization of latest applied sciences that assist create jobs and construct a clear vitality future,” stated Workplace of Know-how Transitions Commercialization Government Rima Oueid. “I’m thrilled to see this mission 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 vitality to the grid or scale back vitality use throughout grid emergencies.


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


V2G expertise works by permitting batteries onboard autos to cost up through the day when vitality, notably renewable vitality akin to photo voltaic is considerable. The batteries then discharge clear electrical energy again to the grid throughout peak hours or different intervals of excessive demand.


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


This V2G mission is a part of SDG&E’s in depth portfolio of fresh transportation and fleet electrification initiatives. To study extra about SDG&E’s Energy Your Drive for Fleet packages, please go to
