Compressed Air Energy Storage, or CAES, is essentially a form of energy storage technology. Ambient air is compressed and stored under pressure in underground caverns using surplus or off-peak power. During times of peak power usage, air is heated (and therefore expands), which drives a turbine to generate power that is then exported to the
