Demand response is a way to reduce the stress on the grid and high electricity prices. By curtailing or reducing the demand for electricity during certain time periods, demand response programs are able to cut prices by reducing the need to run high-cost generators. Instead of supply, or power plants, turning on in response to higher …
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.
