Cajon Valley Union School District electric school buses will support bi-directional energy flow with help from local technology provider Nuvve.  

On July 26, we joined Cajon Valley Union School District, Nuvve, local officials, and the media to celebrate the region’s first vehicle-to-grid (V2G) project. The project connects eight electric school buses to the grid through six bi-directional chargers. Outfitted with software from Nuvve, the new chargers will enable the buses to “fuel up” to run routes as needed and serve as batteries discharging energy back to the grid when parked. With larger batteries than standard electric vehicles and a predictable schedule of operations, electric school buses are an innovative way to help build energy resiliency – especially during the hot summer months. And because buses, like most vehicles, spend most of their day parked, Cajon Valley Union School District can opt to participate in our Emergency Load Reduction Program (ELRP) to earn financial incentives when they send energy back to the grid during times of critical energy needs, as defined by the California Independent System Operator (CAISO).
