Weekly Updates on Energy Storage Projects (May 6, 2025 – May 9, 2025)

Recently, several energy storage stations have made significant progress. Below is a summary of the developments in energy storage projects from May 6 to May 9, 2025:

• 200MW/400MWh Shared Energy Storage Project in Qujing, Yunnan began operations on April 29. This is the first shared energy storage project in Qujing City, successfully connected to the grid. The first phase has an installed capacity of 200MW/400MWh and includes a 220kV energy storage boosting station, connecting to the Shalin substation via a 40-kilometer transmission line. The storage system consists of 8 subsystems and 40 storage units using advanced lithium iron phosphate technology, equipped with an efficient energy management system (EMS) for flexible participation in grid peak shaving and frequency regulation.
• 200MW/400MWh Independent Shared Energy Storage Project by Datang Yunnan successfully connected to the grid on April 30. Located in Yuxi City, the project occupies 61.386 acres and utilizes a lithium iron phosphate battery storage system, installing 80 battery cabins and 40 integrated boosting converter units. It includes a new 220kV boosting station connected to the 220kV Xinpingsubstation through a 1.336-kilometer overhead line.
• World’s Largest High-Temperature Superconducting Energy Storage Device began construction in Zhongshan on April 30, with an expected completion date in November. This project is a demonstration of the national key research and development plan for high-performance superconducting materials and magnetic storage applications, located near the 110kV Binhai substation.
• 100MW/200MWh New Shared Energy Storage Project in Maliqipo, Yunnan was fully connected to the grid on April 30. This project employs a hybrid storage solution combining lithium iron phosphate and all-vanadium flow battery technology, marking Yunnan’s first batch of new energy storage pilot projects.
• 300MW/600MWh Independent Energy Storage Station in Wuzhou, Guangxi began construction on April 30, as part of a major project rollout. This station, developed by Wuzhou Zhongteng New Energy Technology Company, represents a total investment of 1 billion yuan and will occupy approximately 33,360 square meters, with plans for completion by November 2025.
• Shared Energy Storage Station in Pingtan, Fujian successfully completed network tests and began commercial trials recently. This facility, with a capacity of 120MW/240MWh, is the largest of its kind in the province and is expected to help regulate approximately 300 million kWh of electricity annually, promoting renewable energy consumption.
• 100MW/400MWh Iron-Chromium Flow Battery Storage Project in Changzhou, Jiangsu was announced on May 6, with a total investment of 1.8 billion yuan. This project is expected to provide significant peak shaving capacity and consume over 500 million kWh of renewable energy annually.
• 300MW/1200MWh Lithium Iron Phosphate Independent Energy Storage Station in Hebei was connected to the grid on May 7, marking the largest of its kind in the province.
• 100MW/400MWh Energy Storage Station in Inner Mongolia was connected to the grid on May 7, marking the first entirely privately funded independent energy storage project in the region.
• 500MW/2GWh Energy Storage Projects in Xinjiang received approval on May 7, with a total planned investment of 134 million yuan across three projects.
• 100MW/1000MWh Compressed Air Energy Storage Project successfully connected to the grid on May 7, incorporating a 220kV boosting station, which will enhance grid stability and renewable energy consumption.
• 660MW Compressed Air Energy Storage Project in Dunhuang passed feasibility review on May 8, marking progress in the sector.
• 100MW/50.43MWh Independent Hybrid Energy Storage Station in Shanxi commenced operations on May 8, combining flywheel and lithium iron phosphate battery storage technologies.
• 200MW/101.1MWh Independent Hybrid Energy Storage Project in Shanxi signed a cooperation agreement on April 29, with an estimated investment of 800 million yuan.

These developments reflect the ongoing growth and innovation within the energy storage sector, contributing to a more sustainable energy future.
