The Phase I 100MW/200MWh Nanlang energy storage power station, supplied by Sineng Electric, has now been successfully commissioned and put into operation. As the first large-scale standalone energy storage project on the grid side to be completed and commissioned in Zhongshan, China, the facility not only injects enhanced flexibility into the regional power grid, but establishes efficient and reliable revenue mechanism through an innovative frequency regulation service model.
Grid-Forming Foundation, Intelligent Frequency Regulation
The project was invested in and developed by Shennan Dianxiwan (Zhongshan) Company, with Sineng Electric providing the core equipment, 1,250 kW centralized energy storage PCS units. The system is equipped with Sineng Electric’s second-generation enhanced hybrid grid-forming technology, incorporating globally leading IGBT drive technology and advanced intelligent control algorithms. As a result, the solution demonstrates significant advantages in three critical areas including response speed, command latency, and control accuracy, with its comprehensive frequency regulation performance index (K value) ranking among the best in the industry.
Since entering commercial operation six months ago, the power station has become an indispensable “gold-standard auxiliary service provider” for the regional grid. Supported by Sineng Electric’s energy storage PCS as the core equipment, the station has repeatedly delivered high-quality secondary frequency regulation services, effectively smoothing grid frequency fluctuations. The PCS offers flexible, on-demand adjustable ramp rates, reaching up to 50Pn/s, with a response time of ≤5 ms and a control accuracy error of no more than 0.5%. Much like a “speed stabilizer” for a high-speed power system, the solution significantly enhances the stability and reliability of electricity supply for thousands of households.
Sineng Electric has also confirmed its participation in the 14th Energy Storage International Conference and Expo (ESIE 2026), register now to attend Asia’s Largest Energy Storage Trade Show for free:
