12 hours of energy storage enough for U.S. to run on 80% solar+wind
Scientists in California have modeled a solar-heavy/wind power electricity grid, without nationwide HVDC, that could reliably deliver 80% of U.S. electricity needs. 100% of needs would require 3 weeks of energy storage.
California regulators emphasize solar, batteries in utility planning framework
CPUC’s guidance calls for an additional 9 GW of solar and 2 GW of battery storage as the standard against which to compare utility and CCA Integrated Resource plans, and says that new fossil fuel plants must prove a need.
