FAQS about What does electric energy storage capacity mean

What is an energy storage system?

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.

What is electricity storage & how does it work?

This measure will facilitate the deployment of electricity storage. The Bill amends the Electricity Act 1989 to, in effect, clarify that electricity storage is a distinct subset of generation, and defines the storage as energy that was converted from electricity and is stored for the purpose of its future reconversion into electricity.
