The Ordos Gushanliang 300MW/1,200MWh independent energy storage power station, jointly developed by Hunan Corun New Energy Co., Ltd. (CORUN) and members of a large-scale energy storage innovation consortium including Zhejiang Xingchen New Energy Technology Co., Ltd. (SNE), has successfully completed full “three-charge/three-discharge” process testing and acceptance, marking the project’s official commissioning and entry into operation.
Positioned as a core component of the broader Ordos Gushanliang 3GW/12.8GWh energy storage development, the facility is described as the world’s largest single-site grid-forming hybrid energy storage power station. The project combines lithium iron phosphate (LFP) batteries with vanadium flow batteries (VFBs) in a hybrid configuration designed to balance fast power response with long-duration operational stability.
Project highlights
- Global scale, strong grid support: 300MW/1,200MWh grid-forming hybrid energy storage system.
- Clean energy impact (estimated): ~400 million kWh of clean electricity delivered annually, equivalent to reducing fossil energy use by ~160,000 tonnes of standard coal and cutting nearly 400,000 tonnes of CO₂ per year.
- Grid-forming performance: millisecond-level provision of virtual inertia and damping, suppression of wide-band oscillations, and improved disturbance resilience; dual-mode capability for grid-connected and off-grid operation to support local power supply under extreme conditions.
- Designed for harsh conditions: wide-temperature electrolyte solutions, high-strength weather-resistant enclosures, and thermal management (winter insulation/summer heat dissipation) to mitigate sand, wind, and low-temperature impacts; optimized desert construction with support piles anchored into deeper load-bearing layers to reduce settlement risk.
Advancing grid-forming hybrid storage at utility scale
Compared with conventional “grid-following” storage, the Gushanliang project is positioned as an active “smart stabilizer” for the power system—delivering both proactive grid support and multi-timescale energy optimization through the coupling of grid-forming control and hybrid storage. The station is expected to enhance peak shaving, frequency regulation, and voltage support, while accelerating local renewable consumption and efficient power export from wind and solar resources.
Policy alignment and replicable industry value
The project is presented as closely aligned with recent China national guidance encouraging adoption of advanced grid-forming technologies and multi-resource coordinated control to improve system friendliness. In parallel, Inner Mongolia’s policy framework—covering independent storage definition, market positioning, and capacity compensation—supports scale-up of grid-forming storage. Under an expected 10-year policy support period, the project aims to achieve stable operation through a diversified revenue structure combining market trading + capacity compensation + ancillary services.
