The 300 MW compressed air energy storage station in Yingcheng started operation on Tuesday.

With the technology known as "compressed air energy storage'', air would be pumped into the underground cavern when power demand is low while the compressed air would be released to generate power during times of increased demand.

Dubbed as a "super power bank", the station is expected to generate 500 million kWh power annually.
