The job of the grid is to deliver electricity to every customer at 120 volts and 60 hertz. This is accomplished by adding or removing current from the grid. A storage device helps by adding or removing current exactly when needed. Read on to learn how energy storage can strengthen the grid.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
