Researchers at the US Department of Energy (DOE) and Lawrence Berkeley National Laboratory (LBNL) have done the math on California’s 1.5 million zero-emission vehicle (ZEV) mandate and found that the cars’ batteries can meet the goals of the state’s 1.3 GW energy storage mandates by absorbing a healthy amount of daytime overproduction and mitigating the early evening duck curve ramp.
