The Rise of Full Storage Technologies in China

In recent years, China has emerged as a global leader in energy storage technologies, particularly with the advent of the world’s largest pumped storage power plant, the Fengning Pumped Storage Power Station. This facility, which reached full operational capacity at the end of 2024, is pivotal in supporting the country’s renewable energy infrastructure, particularly solar and wind energy. As the demand for efficient energy storage solutions increases, understanding the technical features and different types of storage technologies becomes essential.

Comprehensive Insights into Pumped Storage Technology

Pumped storage is a well-established method for energy storage that utilizes two water reservoirs at different elevations. During periods of low electricity demand, excess energy is used to pump water from the lower reservoir to the upper one. When energy demand peaks, the stored water is released back down through turbines to generate electricity.

The Fengning Pumped Storage Power Station has a total installed capacity of 3.6 GW, featuring 12 reversible pump-turbine units. It is designed to generate 6.61 terawatt-hours (TWh) annually while consuming 8.71 TWh for pumping operations. This facility plays a crucial role in stabilizing China’s power grid, particularly with the increasing share of renewable energy in the generation mix.
