Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in, and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 1960s to 1980s,.

The system allows storing excess wind-generated electricity in the battery when winds are strong, and discharging it when winds are weak to smooth out variability. This improves wind power stability compared to direct connection to the grid. . Energy from fossil or nuclear power plants and renewable sources is stored for use by customers. Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use.
