CFP The Fengning pumped storage power station in north China's Hebei Province, believed to be the largest of its kind in the world, started operations on Thursday. The project's construction started in May 2013. It has a total installed capacity of 3.6 million kilowatts and annual designed generating capacity of 6.612 billion kilowatt-hours.
Capable of harnessing the power of nature and storing and releasing energy as needed, the structure — Fengning Pumped Storage Power Station — is known as the world's largest "power bank". In the valley where the station stands, a pair of reservoirs have been constructed at different elevations.
The latest data from the National Energy Administration showed that as of the end of 2022, the installed capacity of new energy storage projects put into operation nationwide had reached 8.7 million kW, with an average energy storage time of about 2.1 hours, an increase of over 110 percent from the end of 2021.
Since being put into operation, the station has stored and generated 1.4 billion kilowatt-hours of electricity over the past 14 months, supplying electricity sufficient for a year's use for about 500,000 households.
