IEA. Licence: CC BY 4.0. Globally, the pace of demand response growth is far behind the 500 GW of capacity called for in 2030 in the Net Zero Scenario, under which the need for electricity system flexibility – defined as the hour‐to‐hour change in output required from dispatchable resources – more than doubles to 2030.
Energy storage (ES) can mitigate the pressure of peak shaving and frequency regulation in power systems with high penetration of renewable energy (RE) caused by uncertainty and inflexibility.
