CAES involves compressing air and storing it in large repositories such as underground caverns.
CAES is a technology that allows bulk electrical power to be stored on a utility scale and withdrawn on demand when the power is needed. When in compression mode, it also provides a vital load source that prevents the curtailment of intermittent renewable technologies such as wind and solar power, making them easier to integrate into the grid. Second in size only to pumped storage hydropower as a means of bulk energy storage, CAES has the potential to be the lowest cost large-scale energy storage system available.
