On the western side of the Tianshan Mountains, the 75MW/300MWh all-vanadium flow battery ESS power station in Qapqal, Xinjiang, is operating stably. Sineng Electric has provided customized energy storage system solutions for the project, setting a benchmark model for new-type ESS in north-west China. As a key practice in building a new-type power system in Xinjiang, this ESS power station aligns deeply with the region's energy transition needs, achieving engineering breakthroughs in high-altitude and cold regions. Sineng Electric has innovatively developed customized centralized Power Conversion Systems (PCS) capable of full-power operation at DC voltage ranges of 700-1,500V, effectively addressing the wide DC voltage range adaptation requirements of flow batteries and providing critical equipment support for the all-vanadium flow battery ESS project. Since its commissioning, leveraging its 4-hour long duration energy storage (LDES) capability, the project has effectively mitigated the intermittency of wind and solar power output, continuously supporting the stable power transmission of Xinjiang's gigawatt-scale clean energy base.
