Distributed energy storage is considered as the key piece of technology for the smart grid. The distributed energy storage systems (DESSs) can be strategically located and controlled and thus a buffer can be created between utility and nonutility-controlled assets.

Widespread Application of Energy Storage
The advantages and uses of energy storage systems can be :
-relieving overloaded assets on a section of the grid,
-dynamically restoring power to customers during an outage,
-allowing utilities to form capacity from customer-controlled generators

There is a a certain range of power and discharge time performance for the battery used.

Storage for Transmission
and Distribution
Benefits of Electricity Storage

Some storage applications can offer a range of multiple values. If all the available benefits of energy storage could be converted into money by the energy generating companies, they could cover the costs several times. The benefits include:
-mproved reliability
- load leveling
-financial gains from energy arbitrage
- frequency regulation
The above points include both both service- and market-related benefits.
