California Energy Storage Showcase
AIR FORCE VEHICLE-TO-GRID DEMONSTRATION

Plug-in hybrid and electric vehicles with bi-directional charging stations provide transportation capabilities and grid reliability.

The vehicle-to-grid (V2G) demonstration project at Los Angeles Air Force Base uses a non-tactical fleet of 34 light- and medium- duty plug-in electric and hybrid vehicles (PEVs/PHEVs) and their bi-directional charging stations to provide normal daily vehicle capabilities, and reliability to the grid. The vehicles use the grid to recharge the batteries, and the battery-stored energy on board the vehicles becomes an available power grid asset.

This venture represents the first large-scale, market-integrated project to demonstrate full V2G capability, which allows PEV/PHEV owners to earn revenue by making stored energy available to the power grid.

Following the V2G demonstration, some batteries will be removed from the PEVs/PHEVs to evaluate and quantify potential impacts to the batteries from V2G operational cycles and to predict potential long-term impacts. This analysis will provide real-world data on the viability of V2G cost for PEVs/PHEVs, and fill gaps in understanding the potential impacts of V2G operations on PEV/PHEV batteries.
