Energy storage can reduce costs for both grid operators and electricity consumers, simply by balancing peaks in consumption and surplus generation: Many electricity tariffs have time-of-use rates, where electricity prices are increased during high-demand periods. Power consumers with energy storage systems can shape their demand to avoid the
Flywheel Energy Storage: OE supported research, development and deployment of flywheel energy storage technology, most notably for a 25kWh/15-minute storage unit. A highlight of this effort is a pioneering ARRA-OE funded 20MW flywheel storage system for grid frequency regulation on the grid. in an array of 25kWh units.

One grid energy storage method is to use off-peak or renewably generated electricity to compress air, which is usually stored in an old mine or some other kind of geological feature. When electricity demand is high, the compressed air is heated with a small amount of natural gas and then goes through turboexpanders to generate electricity.
