Powered by Zhongchu Guoneng Technology Co., Ltd. (ZCGN) is the world’s largest compressed air power storage undertaking in China. The $207.8 million power storage energy station has a capability of 300 MW/1,800 MWh and makes use of an underground salt cave.
Chinese developer ZCGN has accomplished development of a 300 MW compressed air power storage (CAES) facility in Yingcheng, Hubei province in China.
The firm says the storage plant is the most important CAES system on this planet so far. Previously, the most important CAES facility was a 100 MW undertaking that was turned on in October 2022 on the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, additionally in China’s Hebei province.
ZCGN mentioned the brand new system consists of a multi-stage wide-load compressor and high-load turbine expander, in addition to a high-efficiency supercritical warmth exchanger know-how and built-in management know-how. It claims the power is 30% cheaper than the 100 MW undertaking constructed by the Institute of Engineering Thermophysics and says its total effectivity is 72%.
The $207.8 million facility has an power storage capability of 300 MW/1,800 MWh and occupies an space of roughly 100,000 m2. According to ZCGN, will probably be in a position to present uninterrupted discharge of electrical energy for six hours, making certain electrical energy provides between 200,000 and 300,000 native households throughout peak consumption.
The station makes use of an underground salt cave with wells that attain a depth of as much as 1,000 meters. The cave has a gasoline storage capability of greater than 500,000 cubic meters.
The facility has an estimated annual electrical energy technology of 600 TWh and is projected to avoid wasting about 189,000 tons of ordinary coal consumption. This is reported to scale back carbon dioxide emissions by roughly 490,000 tons per yr.
The undertaking’s investor has revealed plans to supply quite a lot of ancillary companies to generate income by collaborating in China’s electrical energy buying and selling market. The undertaking is predicted to yield an inner fee of return on capital of about 16.38%, with a payback interval of about 7.1 years.

The May version of the pv journal examines international polysilicon oversupply and China’s tightening funds, seems on the burgeoning US photo voltaic glass business, updates readers on the most recent perovskite developments, and considers easy methods to enhance PV when the bullets are flying. All these further elements come from Turkey, Italy, Azerbaijan, and many others.
It is predicted to supply necessary energy regulation capabilities within the energy grid of Shandong province, together with peak shaving, frequency stabilization, section shifting, and standby energy.
