what is small energy storage

Energy Storage | Electricity Canada
With energy storage, we can capture electricity during times of low demand and return it to the grid during periods of greater need. Convenient and economical energy storage can: Increase grid flexibility. Simplify the integration of distributed generation and electric vehicles. Improve power quality. Limit periods of asset overload.
