Access huge amounts of energy when you need it. Compressed air energy storage (CAES) is a proven large-scale solution for storing vast amounts of electricity in power grids. As fluctuating renewables become increasingly prevalent, power systems will face the situation where more electricity is produced than it is needed to cover the demand.

One function the Compressed Air Energy Storage (CAES) technology is very good at is load shifting. Load shifting is achieved by storing energy during periods of low demand and releasing the stored energy during periods of high demand. The NETL (2008) study notes that load shifting comes in several different forms.
