Executive summary Batteries are an essential part of the global energy system today and the fastest growing energy technology on the market Battery storage in the power sector was the fastest
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. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed. They further provide essential grid services, such as helping to restart the grid
