China Launches First Phase Of 300 MW/1200 MWh Electrochemical Energy Storage Project

The first phase of China’s largest electrochemical energy storage station, with a capacity of 300 MW/1200 MWh, has been successfully commissioned. The project is powered by SINEXCEL’s 1725 kW utility-scale Power Conversion System (PCS), marking a major milestone toward full-capacity operation. This achievement is expected to improve grid stability and support the faster adoption of clean energy across the region.

The site represents one of the two locations being developed under the overall 600 MW/2400 MWh project. It includes 240 battery containers and 60 prefabricated cabins. Once fully completed, the entire project will operate as an integrated “wind–solar–thermal–storage–transmission” model. This approach is designed to maximize the use of renewable energy resources and strengthen system flexibility for long-term energy security.

SINEXCEL provided 60 prefabricated cabins equipped with 180 units of its 1725 kW PCS. The PCS delivers peak efficiency of up to 98.5% and uses advanced multi-string architecture to ensure improved battery protection. It supports flexible battery configurations with 1, 2, 4, or 8 strings and features a combined AC/DC output to simplify system control and allow for future expansion. The system includes IP54-rated outdoor cabinets and offers a rapid 10 ms response time to support real-time grid balancing. It also meets compliance standards in major global markets, including North America, Europe, Australia, Japan, and China.

SINEXCEL has deployed energy storage solutions in over 40 countries, with more than 5,000 installations and over 12 GW of cumulative storage capacity. Its participation in major landmark projects demonstrates the company’s strong technical capability and commitment to building a more resilient and sustainable energy future.
