This is the best summary I could come up with:

Chinese developer ZCGN has completed the construction of a 300 MW compressed air energy storage (CAES) facility in Feicheng, China’s Shandong province.

Previously, the largest CAES facility was a 100 MW project switched on in October 2022 by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, also in China’s Hebei province.

It claimed that the facility was 30% cheaper than the 100 MW project built by the Institute of Engineering Thermophysics and said its overall efficiency is 72%.

The $207.8 million facility boasts an energy storage capacity of 300 MW/1,800 MWh and occupies an area of approximately 100,000 m2.

The facility has an estimated annual electricity generation of 600 TWh and is projected to save about 189,000 tons of standard coal consumption.

The project’s investor has disclosed plans to offer various ancillary services to generate revenue through participation in China’s electricity trading market.
