Electrical Energy Storage: an introduction
Introduction. Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years.

Electric Energy Storage
The use of electric energy storage is limited compared to the rates of storage in other energy markets such as natural gas or petroleum, where reservoir storage and tanks are used. Global capacity for electricity storage, as of September 2017, was 176 gigawatts (GW), less than 2 percent of the world''s electric power production capacity.
