What is energy storage?

Energy storage is the capture of energy for use at a later time, and a battery energy storage system is a form of energy storage.

Battery energy storage has a variety of useful applications, such as balancing energy demand and supply for either the short or long term. This ensures the grid operates more efficiently. Plus, batteries are able to respond to changing supply or demand levels within a second.
