Major Milestone in Energy Storage

On December 4, 2025, the first phase of what will become China's largest electrochemical energy storage station was officially commissioned. This groundbreaking project, boasting a capacity of 300 MW and 1200 MWh, leverages SINEXCEL's advanced 1725 kW Power Conversion System (PCS). This development is a significant milestone in the country's efforts to stabilize its energy grid and promote the adoption of clean energy sources.

Overview of the Project

Located in Shenzhen, this energy storage facility includes an impressive configuration of 240 battery containers alongside 60 prefabricated cabins. Its expansive setup is designed to eventually encompass a total capacity of 600 MW and 2400 MWh, which will play a vital role in an integrated energy model combining wind, solar, thermal, and storage capabilities. This sustainable approach is aimed at optimizing renewable energy utilization while enhancing overall system flexibility and reliability.

Technical Specifications

SINEXCEL has supplied 60 prefabricated cabins equipped with 180 units of its 1725kW PCS, which promises a peak efficiency of up to 98.5%. The PCS employs innovative multi-string technology, which not only enhances battery protection but also allows for flexible configurations that support either 1, 2, 4, or 8 battery strings. This advanced system controls both AC and DC outputs, paving the way for simplified operation and future expansion opportunities. NEMA 3R-rated cabinets ensure that the equipment remains reliable even in outdoor conditions. A remarkable response time of just 10 milliseconds enhances real-time grid balancing capabilities, conforming to compliance standards across several global markets, including North America, Europe, Japan, Australia, and China.

Positive Impacts on Energy Sustainability

The commissioning of this energy storage station provides significant benefits for the energy landscape in China, a country keen to reduce its carbon footprint and shift toward more sustainable energy practices. Once fully operational, this facility will bolster the stability of the local electricity grid, enabling better integration of renewable resources. The project represents a critical step in transitioning to a cleaner, more resilient energy future that aligns with global sustainability goals.
