Giant batteries are transforming the way the US uses electricity

Giant batteries are delivering solar power after dark in California and helping to stabilize grids in other states.

California draws more electricity from the sun than any other state. It also has a timing problem: Solar power is plentiful during the day but disappears by evening, just as people get home from work and electricity demand spikes. To fill the gap, power companies typically burn more fossil fuels like natural gas.
