IEEE: a group of interconnected loads and Distributed Energy Resources (DER) with clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to enable operation in both grid-connected or island modes.

To accumulate energy produced by large, less

responsive thermal generation plants (also RE) and then re-dispatch it based on peak demand.

Storage facilities were largely financed by

arbitrage (buying energy at a low price and selling it at a higher price).

Energy storage currently contributes to

reliability, efficiency, power quality, transmission optimization, black-start functions, and support Demand Response (DR) function.
