China launches first phase of 300 MW storage station

China has completed the commissioning of the first phase of an electrochemical energy storage station with a capacity of 300 MW/1,200 MWh. This project represents half of a total 600 MW/2,400 MWh programme, backed by public investment aimed at strengthening the reliability of the national power grid. The facility uses a 1,725 kW Power Conversion System (PCS) supplied by SINEXCEL to support large-scale grid response.

A project supporting national energy integration

The site includes 240 battery containers and 60 prefabricated cabins. Once fully operational, the project will combine wind, solar, thermal and storage capacities into a single integrated system. Authorities consider this approach a way to accommodate increasing renewable output while ensuring reliable supply continuity for consumers.

The equipment supplied by SINEXCEL comprises 180 PCS units across 60 cabins to manage the installed capacity. Its built-in multi-string technology protects batteries and supports multiple configurations, allowing future system expansion.

Infrastructure meeting global standards

The PCS cabinets are IP54 certified for continuous outdoor operation, even in challenging environments. A 10-millisecond response time ensures immediate frequency stabilisation in the event of significant grid fluctuations. The equipment complies with regulations across North America, Europe, Australia, Japan and China, enabling potential wider deployment.

SINEXCEL reports an operational footprint in over 40 countries and more than 5,000 installations worldwide. The company’s total deployed storage capacity exceeds 12 GW, covering public infrastructure and industrial networks. This commissioning supports national objectives to enhance grid management capabilities through publicly funded large-scale storage initiatives.
