Jointly constructed by China Gezhouba Group, a subsidiary of Energy China(@EnergyChinaNews), the lower reservoir of Fengning Pumped Storage Power Station officially began storing water. With an installed capacity of 3,600 MW, the project has been under construction from May 2013, and will be the largest pumped-storage power station in the world after completion. Moreover, every year, it will store 8.8 billion kWh of excess electricity, generate 6.612 billion kWh of power, save 480,800 tons of coal and reduce 1.2 million tons of carbon emissions (equivalent to more than 160 square kilometers of afforestation).
