Massive Scale and Strategic Investment in Shanxi

The Shanxi Jinbei coal mining subsidence area new energy base has officially broken ground on a monumental 820MW/3280MWh energy storage project. Transforming a former coal mining region into a hub for clean energy, this project represents a total investment reaching 2.394 billion RMB. It marks a significant milestone in China's long-duration energy storage infrastructure, strategically designed to stabilize the regional grid and integrate high volumes of intermittent renewable energy into the local power network.

Innovative Hybrid Storage Architecture

A standout feature of this mega-project is its hybrid electrochemical storage model, specifically implemented at the Yunguang North Station. The station incorporates a combined scheme of 80MW lithium iron phosphate batteries and 20MW vanadium redox flow batteries. This innovative hybrid approach leverages the rapid response and high power density of LFP technology while utilizing the VRFB specifically for long-duration capacity. This ensures a prolonged, stable, and safe power supply during peak demand or low renewable generation periods, mitigating the risks associated with single-chemistry systems.

EPC Contracts and Aggressive Timeline

Construction momentum is already building rapidly, as EPC contracts for the project's three main sections were awarded in early September, totaling over 2.3 billion RMB. The massive construction responsibilities are shared among industry giants, including the China Energy Engineering Northwest Electric Power Design Institute, PowerChina Jiangxi, and PowerChina Northwest. The project operates on an aggressive timeline, with comprehensive plans to be fully grid-connected and commercially operational by December 31, 2026, demonstrating the rapid deployment capabilities of the energy sector. This deployment underscores the growing recognition of flow batteries in hybrid configurations for grid-scale resilience.

The project adopts a 4-hour electrochemical storage model, utilizing the VRFB for long-duration capacity to ensure prolonged power supply across the Jinbei new energy base.
