Yunnan Unveils 1.9GW/7.6GWh Shared Energy Storage Project List
Yunnan Province has officially released its 2026 new shared energy storage project list, marking a significant milestone in the region's renewable energy infrastructure. The comprehensive list features 13 projects with a total planned scale of 1900MW/7600MWh, representing a 4-hour duration system designed to bolster grid stability and support new energy integration. This ambitious rollout reflects the province's aggressive strategy to integrate high proportions of variable renewable energy into its grid while maintaining reliable power supply.
Flagship 300MW Vanadium Flow Battery Project
At the forefront of this initiative is the massive independent battery energy storage project in Gengma County, Lincang City. This flagship project has officially completed its signing process, boasting a total investment of 1.5 billion RMB. With an installed capacity of 300MW/1200MWh (4-hour duration), it will utilize advanced all-vanadium redox flow battery technology.
As the largest project in Yunnan's 2026 new shared energy storage scale, the Gengma project is designed to operate in synergy with centralized photovoltaic power plants. This 'solar-storage coordination' model is expected to significantly enhance the regional power grid's regulation capabilities and mitigate the intermittency of renewable energy sources.
Boosting Regional Grid Stability
The rollout of these 13 shared energy storage projects underscores Yunnan's commitment to building a robust, flexible, and sustainable energy ecosystem. By leveraging long-duration energy storage (LDES) technologies like vanadium flow batteries, the province aims to maximize the utilization of its abundant solar and wind resources. Furthermore, the shared storage model allows multiple renewable energy generators to access storage capacity without the need for individual, capital-intensive infrastructure investments.
The Gengma project, with a capacity of 300MW/1200MWh, is the largest in Yunnan's 2026 shared energy storage scale, utilizing all-vanadium redox flow battery technology.
These strategic investments will not only accelerate the local energy transition but also provide valuable operational insights for large-scale LDES deployment across China's diverse geographical landscapes.
