Sustainable Solutions: 48 MW / 96 MWh Energy Storage Station in Xuwei New District

On July 25, 2024, Ceepower contributed to the full-capacity grid integration of a 48 MW / 96 MWh energy storage station in Lianyungang's Xuwei New District. As the region's first large-scale electrochemical storage system, it marks a key step in the district's move toward sustainable energy.

With its rapidly growing energy demands, Xuwei New District needed a reliable energy storage solution to support its green development goals. The challenge was to seamlessly integrate the system into the existing grid while ensuring long-term efficiency.

Ceepower Xiangrui Electrical Engineering Co., Ltd., a subsidiary of Ceepower, provided EPC services for the project, while Beijing Ceepower Xindian Technology Co., Ltd., another Ceepower subsidiary, handled secondary equipment integration and technical support.

The energy storage station, spanning approximately 7,000 square-meter, is designed with an outdoor prefabricated cabin layout. It includes 12 PCS integrated units and 24 battery cabins, creating 24 storage units that connect to the 110 kV step-up substation at Nacha Riverbank via two 35 kV collection lines. This compact and efficient design ensures optimal performance and reliability.

At the core of the system lies Ceepower's independently developed Energy Storage Station Monitoring and Energy Management System, delivering real-time monitoring and management to guarantee the long-term efficiency and safety of the battery systems.

The successful commissioning of this energy storage station is a major step forward for Xuwei New District in building a modern, integrated power system that supports renewable energy.

The project is expected to generate 390 GWh of green electricity annually, reducing carbon dioxide emissions by 340,000 tons, sulfur dioxide by 185 tons, and nitrogen oxides by 169 tons each year. This initiative enhances energy security while advancing the district's environmental objectives.
