Summary

San Diego Gas & Electric Cajon Valley Union School District Electric Bus System tests the technology that enables eight electric school buses to put electricity back on the grid when needed such as on hot summer days. A collaborative effort between SDG&E, the Cajon Valley Union School District and locally based technology company Nuvve, this is the first vehicle-to-grid (V2G) project to become operational in Southern California, helping to advance clean air and climate goals while also bolstering grid reliability.

Vehicle to Grid Charging

This is the first V2G project to come online in the nation, following the U.S. Department of Energy’s (DOE) vehicle-to-everything (V2X) initiative announcement in Los Angeles in April. SDG&E, which started on the project prior to the announcement, is a signatory to the department’s V2X memorandum of understanding (MOU). The agreement is designed to bring together resources from DOE National Labs, state and local governments, utilities, and private entities to unlock the potential of bi-directional charging to increase energy security, community resilience, and economic growth while supporting the nation’s electric system.

As part of the five-year pilot project, SDG&E installed six 60kW bi-directional DC fast chargers at Cajon Valley’s bus yard in El Cajon.

On average, cars are parked 95% of the time. California is home to 1.1 million EVs, the largest concentration of EVs in the nation. Starting in 2035, all new cars and passenger trucks sold in California are required to be zero-emissions. Many local agencies and local companies are working to transition to electric fleets under SDG&E’s Power Your Drive for Fleets program, which provides infrastructure support. In addition to Cajon Valley, SDG&E is also working with San Diego Unified and Ramona Unified School Districts on V2G projects.

With the bi-directional chargers now in operation, Cajon Valley can participate in SDG&E’s new Emergency Load Reduction Program (ELRP), which pays business customers $2/kWh if they are able to export energy to the grid or reduce energy use during grid emergencies.

V2G technology works by allowing batteries onboard vehicles to charge up during the day when energy, particularly renewable energy such as solar is abundant. The batteries then discharge clean electricity back to the grid during peak hours or other periods of high demand.

This V2G project is part of SDG&E’s extensive portfolio of clean transportation and fleet electrification initiatives. To learn more about SDG&E’s Power Your Drive for Fleet programs, please visit sdge.com/fleet.
