- China has completed the deployment of all storage cabins for its largest electrochemical storage project, which was part of the first UHV transmission project.
- Sinexcel delivered PCS systems for this project and a 220-MW installation in Ningxia, enabling both sites to supply over 1,000 GWh of renewable energy annually.
In a significant stride toward renewable energy integration, China has completed the deployment of all storage cabins for its largest electrochemical energy storage project to date. The massive installation, totalling 600 MW/2,400 MWh, marks a critical milestone in the nation’s clean energy infrastructure.
Shenzhen Sinexcel Electric Co., Ltd announced the completion on Wednesday, June 11, highlighting its role as the 1,725-kW Power Conversion Systems (PCS) project provider. The installation is part of China’s first ultra-high voltage (UHV) transmission initiative that combines wind, solar, thermal, and battery storage technologies.
Meanwhile, the project’s first site now houses 240 battery containers and 60 PCS skids, enabling the integration of approximately 840 GWh of renewable energy into the national grid each year. According to Sinexcel, each full charge of the system stores up to 2.4 GWh of electricity, enough to significantly stabilise intermittent renewable output.
Significantly, this development enhances grid reliability and positions China at the forefront of scalable, integrated energy systems. By harnessing UHV technology, the project ensures efficient transmission of green energy across vast distances, supporting regions with less renewable generation capacity.
Simultaneously, Sinexcel has also completed the delivery and grid connection of PCS skids for a 220-MW/880-MWh energy storage project in Ningxia, a province renowned for its abundant solar resources. This facility is fully operational and expected to supply nearly 200 GWh of electricity annually. The project strengthens energy reliability in northwestern China while reducing dependence on fossil fuels.
With both projects now active, Sinexcel underscores its growing influence in China’s renewable energy transition. These advancements contribute to carbon reduction goals and set a new benchmark for large-scale battery storage integration globally.
As China continues to expand its clean energy capabilities, projects like these play a vital role in achieving a stable, resilient, and sustainable power grid for the future.
