On the longevity end, you'll discover trailer-sized stream batteries like vanadium redox and zinc-bromide and high-temperature batteries like sodium-sulfur. These techniques cannot ship huge electricity to prospects all day, like pumped hydroelectric and CAES can. Storage devices make and use current cleverly -- for a process that may be reversed to give the current back. This scenario sets utilities up to make kind of electricity than prospects use.

It spikes when utilities make extra electricity than clients use and dips when utilities make less.
