The operation of a conventional compressed air energy storage system is described as follows: excess electricity during off-peak hours is used to drive a 2-stage compressor with intercooling. After the compression, the compressed air (40–70 bar) is led to an after-cooler before it gets stored in an underground storage reservoir.
