Grid energy storage is used to shift generation from times of peak load to off-peak hours, helping to balance supply and demand. Power plants can run at their peak efficiency during nights and weekends, and this strategy can also reduce the cost of supplying peak power or compensate for the intermittent generation of wind and solar power.
Grid energy storage, also known as large-scale energy storage, is a collection of methods used for energy storage on a large scale within an electrical power grid.
Energy storage technologies can potentially address grid concerns viably at different levels. This paper reviews different forms of storage technology available for grid application and classifies them on a series of merits relevant to a particular category.
