300 MW / 1,200 MWh Grid-Forming Energy Storage Power Station in Ordos Achieves Commercial Operation with Sineng Electric’s Advanced Energy Solution – EQ
Ordos, China – Sineng Electric has supported the commercial operation of a 300 MW / 1,200 MWh energy storage power station in Ordos City, China, after the successful completion of rigorous three-charge/three-discharge performance validation testing. Powered by Sineng’s 1250 kW central PCS featuring next-generation enhanced grid-forming technology, the project represents the world’s largest single-site grid-forming hybrid energy storage power plant, integrating multiple energy storage technologies and operating modes.
As a key part of the region’s 3 GW / 12.8 GWh energy storage deployment, the facility employs a hybrid configuration combining Lithium Iron Phosphate (LFP) batteries with Vanadium Flow Batteries (VFBs), balancing fast power response with long-duration energy stability. Sineng’s next-generation central and string PCS solutions support grid-forming, grid-following, and off-grid operation modes, ensuring operational flexibility across complex and variable grid conditions.
Equipped with enhanced grid-forming technology, Sineng’s energy storage solution provides millisecond-level power support, virtual inertia and damping support, suppressing wide-frequency oscillations under both major and minor grid disturbances. In grid outage scenarios, the solution enables minute-level black-start functionality, allowing rapid power restoration and strengthening overall grid resilience.
Leveraging Sineng Electric’s grid-forming solution and AI-powered intelligent energy management system, the plant optimizes energy dispatch, maximizes system efficiency, lifecycle performance, and economic returns—creating sustained long-term value for customers.
Notably, Sineng Electric has successfully completed whole-station-level grid-forming testing, further validating the reliability and large-scale applicability of its advanced grid-forming technology. This achievement underscores Sineng Electric’s leadership in energy storage and its role in advancing a stable, resilient, and sustainable power system.
