In order to cope with both high and low load situations, as well as the increasing amount of renewable energy being fed into the grid, the storage of electricity is of great importance. However, the large-scale storage of electricity in the grid is still a major challenge and subject to research and development.
Electrical energy is stored at times when electricity is plentiful and cheap (especially from variable renewable energy sources such as wind and solar), or when demand is low, and later returned to the grid when demand is high and electricity prices tend to be higher.
Instead, they store electricity that has already been created from an electricity generator or the electric power grid, which makes energy storage systems secondary sources of electricity. Energy storage systems use more electricity for charging than they provide when supplying electricity to the electricity grid.
Grid energy storage. Before we dive into the topic, it''s important to understand what it means to store energy. The job of the grid is to deliver electricity to every customer at 120 volts and 60 hertz. This is accomplished by adding or removing current from the grid. A storage device helps by adding or removing current exactly when needed.
