Date: 2024-11-12

Recently, the construction of the lower and upper reservoir dams for the Zhejiang Songyang Pumped Storage Power Station started, marking the beginning of a new phase in the power station’s development.

The Songyang Pumped Storage Power Station is designed with a total installed capacity of 1.4 million kilowatts. It will feature four single-stage reversible pump-turbine generator units, each with a capacity of 350,000 kilowatts.

Once operational, the station is expected to generate an average of 1.4 billion kilowatt-hours of electricity annually, with a pumping capacity of 1.9 billion kilowatt-hours.

The station, set to begin operations with its first unit in late 2027, will support peak load balancing, energy storage, and emergency backup for the power grid of east China's Zhejiang Province while also contributing to the stability of the East China grid.
