World's Largest Single-Unit Hybrid Energy Storage Power Station Deployed in China

The Tunnel Engineering Co. Ltd., a leading Chinese construction company, has successfully connected the world's largest single-unit "supercapacitor + lithium battery" hybrid energy storage power station to the grid. The power station, located in the northwest Shanxi region, is designed to stabilize the grid frequency and facilitate the consumption of new energy sources. By combining the strengths of supercapacitors and lithium-ion batteries, the power station can provide millisecond-level response speed and ultra-precise output, addressing the limitations of traditional thermal power generation.

Key Takeaways:

The China Power Jingu Pianguan Hybrid Energy Storage Independent Frequency Regulation Power Station is the world's largest single-unit "supercapacitor + lithium battery" hybrid energy storage power station, designed and constructed by Tunnel Group Shanghai Energy Construction.
The power station will participate in grid frequency regulation with a "second-level response" speed, establishing an efficient and stable "green channel" for new energy consumption in northwestern Shanxi.
The hybrid energy storage power station combines the strengths of supercapacitors and lithium-ion batteries to provide millisecond-level response speed and ultra-precise output, overcoming the limitations of a single energy storage technology.
The power station can stabilize the grid frequency and facilitate the consumption of new energy sources, such as wind and photovoltaic power, with a response speed that is 60 times faster than traditional thermal power units.
The average output error of energy storage is less than 1%, which can further improve the output accuracy of battery energy storage frequency regulation and enhance the frequency regulation effect.
The hybrid energy storage solution can reduce the adverse damage caused by frequent battery charging and discharging, significantly improving the overall profitability of the power station.
The project is estimated to generate annual revenue exceeding 100 million yuan and provide significant economic benefits, taxes, and a replicable model for the absorption of new energy nationwide.
The project is an active response and effective implementation of the policy guidance in the "Guiding Opinions on Accelerating the Development of New Energy Storage" issued by the National Development and Reform Commission and the National Energy Administration.
