Why do we need a grid-scale energy-storage system?
Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.
How does a power grid work?
