The electricity grid is a complex system in which power supply and demand must be equal at any given moment. Historically, supply has been adjusted to meet changes in demand, from the daily patterns of human activity to unexpected changes such as equipment overloads, wildfires, storms, and other extreme weather events. ... Energy storage is ...
We also need a mixture of energy storage that is very-short-term (milliseconds to seconds) to stabilise the electricity grid and control voltage and phase, short-term (hours) to stabilise electrical energy systems and provide uninterruptible power supply, and long-term (days to years) to resupply the energy system.
