Nuvve announced its GIVe software platform successfully aggregated Cajon Valley Union School District (CVUSD) buses into a virtual power plant (VPP) and discharged electricity back to the grid, according to the company's news release.
The aggregation took place during one of nine heat events in California, according to Nuvve. During the nine separate heat events, Nuvve said it used the buses to discharge 650 kWh of energy back to the grid.
This project is a collaborative effort between San Diego Gas and Electric (SDG&E), CVUSD, and Nuvve, according to the company's news release.
Nuvve said it received funding under SDG&E’s Electric Load Reduction Program (ELRP) for those energy exports which is shared with the CVUSD.
Nuvve recently interconnected its vehicle-to-grid (V2G)- capable charging stations in July 2022 to service an electric school (EBS) bus fleet owned by the CVUSD.
Through the partnership, electric school bus fleets (ESBs) equipped with V2G charging through Nuvve's GIVe platform can provide energy back to the grid during emergency load reduction events, allowing customers to participate in energy conservation efforts in the event of a grid emergency and get paid for their load reduction results.
“This pilot project with Nuvve is a great example of our region being at the forefront of testing and adopting innovative technologies to reduce greenhouse gas emissions and strengthen the electric grid," said Miguel Romero, SDG&E VP of energy innovation. "Electric fleets represent a vast untapped energy storage resource and hold immense potential to benefit our customers and community not just environmentally, but also financially and economically.”
According to Nuvve, there will be more of Nuvve’s V2G-capable charging stations that will interconnect in SDG&E’s service territory. The company said it will aggregate more ESB fleets as VPPs across multiple school districts for future California Independent System Operator (CAISO) emergencies.
“As a San Diego-based company, Nuvve cares about our community and about partnering with local school districts to provide clean transportation to students," said Gregory Poilasne, Nuvve CEO. "Electric school buses reduce the impact on the grid while parked, and ultimately help fight the effects of climate change.”
