A 240 MWh energy storage facility has been commissioned in the city of Taizhou, Jiangsu Province, marking a new milestone for autonomous energy projects in China. Developed by Jingjiang Taifu New Energy, the system is directly connected to the Jingjiang Special Steel site and is now the largest operational behind-the-meter storage infrastructure in the region, with an output capacity of 120 MW.
Direct support for critical industrial needs
The installation is designed to stabilise the industrial site’s energy supply while reducing pressure on the local grid. It can provide 120 MW of frequency regulation and peak shaving, particularly during summer demand peaks. The integration of grid-forming inverter technology ensures rapid responsiveness, enabling flexible operation and better adaptation to load variations.
The system is expected to integrate up to 168 million kilowatt-hours of renewable electricity annually. This volume corresponds to an estimated replacement of 20,700 metric tons of standard coal and an annual reduction of approximately 51,500 metric tons of carbon dioxide emissions. The facility promotes the local use of intermittent sources while reducing dependence on the main grid.
A targeted strategy led by State Grid
This deployment is part of a coordinated strategy led by State Grid Taizhou Power Supply Company and the Marketing Service Center of State Grid Jiangsu Electric Power. By applying a model to assess on-site storage potential, the teams identified energy-intensive industrial consumers with high economic value for such systems. The approach included detailed consumption analysis and full technical support up to grid integration.
To date, total operational behind-the-meter storage capacity in Taizhou exceeds 220 MW. This momentum also relies on the Urban Energy Storage Cloud Platform, a digital platform launched in April 2025, which enables real-time supervision of all connected assets. Forty-two storage units are currently integrated, with a combined capacity of 188 MW.
Towards a replicable model for heavy industry
The Jingjiang Special Steel site also serves as a demonstration project for future initiatives combining energy storage and distributed generation. The initiative aims to support the emergence of optimised industrial microgrids capable of coordinated operation and enhancing the local reliability of power supply. The project also increases the grid’s capacity to absorb surplus renewable energy.
By multiplying on-site infrastructures, industrial operators can now secure their supply, optimise energy costs, and contribute to the modernisation of the regional energy landscape without relying solely on national transmission capacity.
