What is an Energy Storage System
A battery energy storage system is a sub-set of energy storage systems, using an electro-chemical solution. In other words, a battery energy storage system is an easy way to capture energy and store it for use later, for instance, to supply power to an off-grid application, or to complement a peak in demand.
