Currently the Largest-Scale Form of Grid Storage Available
Last week, California's PG&E filed a request with regulators to study the feasibility of building a new "pumped hydro storage" facility in the Mokelumne River watershed in Amador County. It would store energy by pumping water from a low reservoir to another one that is at a higher elevation. This is done when there's a surplus of energy, such as when the wind is blowing hard at night, for example. Then when you need the energy, you open up the valves and let the water run through turbines like any other hydro station....
