Construction of SW China mega pumped storage hydropower project underway

In addition to water pumped from the lower reservoir to the upper reservoir, the project under construction will also use natural water sources, such as rainwater and river runoff -- that flow into the upper reservoir -- to produce electricity.

Four reversible hydro-generator units, each with a capacity of 300,000 kW, are planned to be installed. Combined with the existing 3-million-kW installed capacity of the Lianghekou hydropower plant, the total installed capacity of the new project is expected to reach 4.2 million kW.
