LBNL Report: EVs Could Achieve Same Goal as Storage in California, at Fraction of Cost
EVs support the state's renewable integration targets while avoiding much of the tremendous capital investment of stationary storage that can instead be applied towards further deployment of clean vehicles
May 30, 2018 -- California is in the process of deploying substantial amounts of renewable generation, targeting 50% of grid-supplied energy coming from renewables by 2030. A new study by researchers at the Lawrence Berkeley National Lab forecasts the significant grid challenges that arise as more renewables are deployed, specifically the increasing daytime over-generation, increasing evening peaks, and increasing up-ramp and down-ramps.
The study shows that EVs with only V1G capability provide renewables integration capability equivalent to 1.0 GW of stationary storage, a large fraction of the 1.3 GW Storage Mandate, but at a small fraction of the cost. With some vehicles being V2G capable by 2025, vehicles provide renewables integration capability far exceeding that of the Storage Mandate during critical days.
The results show that substantial capital investment, as much as several billion dollars, can be avoided if EVs are used in lieu of stationary storage. In other words, the California Storage Mandate can be accomplished through the ZEV Mandate, provided that controlled charging is also widely deployed. The capital investment for stationary storage can instead be redirected to further accelerate the deployment of clean vehicles and vehicle-grid integration, and could even be used to pay EV owners when their vehicles are grid-connected with controlled charging.
In this manner, the study finds that not only are clean vehicles an enabler for a clean electricity grid at substantially lower capital investment, but the avoided costs of supporting renewables with stationary storage can be used to further accelerate the deployment of clean vehicles.
