Recently, multiple new energy storage projects across China have reached important milestones. In Shandong, Xinjiang, Hebei, Qinghai, and Inner Mongolia, several 100-MW-level projects have either started construction or successfully connected to the grid. Technologies involved include flywheel storage, lithium iron phosphate (LFP) batteries, hydrogen storage, and more - together painting a rapidly emerging panorama of diversified and large-scale storage development.

Breakthrough in Grid Frequency Regulation: World's First 100-MW

Flywheel Storage Demonstration Project Commissioned

The world's first 100-MW independent flywheel frequency-regulation demonstration plant - the Boding Energy 100 MW Vacuum Magnetic Suspension Flywheel Independent Frequency Regulation Project (Phase I) - has officially been commissioned in Rushan, Weihai, Shandong. Sungrow's energy storage PCS integrated system introduced multiple hardware and software innovations tailored for flywheel storage, achieving key breakthroughs in response speed and operational reliability, and setting a new benchmark for frequency-regulation applications.

Phase I of the Rushan Bodin flywheel project was grid-connected in July, and Phase II has already been included in Shandong's 2025 New Energy Storage Demonstration Program. The project's successful commissioning verifies Sungrow's PCS stability and rapid system response in flywheel-based frequency regulation, enhances overall operational efficiency, and lays a strong foundation for large-scale deployment of flywheel energy storage in grid applications.

CGN's 200 MW / 800 MWh Independent Energy Storage Project in

Lop County, Xinjiang Breaks Ground

On November 16, CGN (China General Nuclear Power Group Co., Ltd.)'s 200 MW / 800 MWh independent energy storage project in Lop County, Hotan Prefecture, Xinjiang officially started construction. Located about 20 km from Luopu County, the project is invested in and developed by CGN New Energy Lop Co., Ltd., and constructed by China Energy Engineering Xinjiang Electric Power Construction Co., Ltd.. The project will build a centralized electrochemical storage station with a planned total capacity of 200 MW / 800 MWh.

Hebei Zhuozhou 200 MW / 800 MWh Independent Energy Storage

Project Starts Construction

On November 18, construction officially began on the 200 MW / 800 MWh independent energy storage station in Zhuozhou, Hebei. As a key pilot project supported by Hebei Province, it carries a total investment of over 1 billion RMB. Jointly developed by DURIA TECH, CORUN, CALB, and Guoxia Technology, the project establishes a full-chain closed-loop system from upstream materials to mid-stream equipment and downstream operations - advancing integrated “project development + supply chain security + full-cycle services.”

The project adopts a hybrid “lithium iron phosphate + nickel-metal hydride” storage technology route. Once completed, it will significantly enhance peak-shaving and frequency-regulation capability for the Beijing-Tianjin-Hebei grid, supporting efficient renewable-energy consumption and improving grid safety and stability.

150 MW / 600 MWh: SPIC Qinghai Haixi Grid-Side Storage Project

Breaks Ground

On November 13, Huanghe Hydropower Development Co., Ltd. Under the SPIC (State Power Investment Corporation Ltd.) held a groundbreaking ceremony for the Qinghai Haixi Tuosu grid-side electrochemical storage project at the Yixuan PV power station. The project is part of the supporting storage facilities for the first phase of the company's 2.2 GW multi-energy complementary project in Delingha. With a planned capacity of 150 MW / 600 MWh, the station will significantly enhance the grid's peak-shaving ability and its capability to absorb PV and other renewable generation.

The project includes a 100 MW / 400 MWh centralized storage system and a 50 MW / 200 MWh high-voltage cascaded storage system, both designed to provide reliable power support during peak demand periods.

300 MW / 600 MWh: Xinjiang's First Immersed Energy Storage

System Commissioned

On November 9, the energy storage project invested by Xinjiang Weilan New Energy Technology Development Co., Ltd. - the first large-scale electrochemical energy storage station in the Xinjiang Production and Construction Corps (XPCC) and the first immersed energy storage system in Xinjiang - successfully completed all equipment commissioning and was energized and put into operation.

The project turns “technological firsts” into “industry benchmarks,” adopting a mature immersed-system design paired with high-safety LFP batteries. As Xinjiang's first immersed-system energy storage project, it can control battery operating temperature differences within ≤2 °C. Combined with its large 300 MW / 600 MWh configuration, the project fills the technical gap for large-scale electrochemical storage within the XPCC.

100 MW / 400 MWh: Independent Grid-Side Storage Demonstration

Project in Huade, Ulaanqab (Inner Mongolia) Successfully Connected

On November 13, the electrochemical portion of the Huade County grid-side independent energy storage demonstration project in Ulaanqab, Inner Mongolia, was successfully connected to the grid. The project includes a total planned capacity of 100 MW / 400 MWh, adopting a hybrid “electrochemical + hydrogen storage” configuration:

Electrochemical storage: 90 MW / 360 MWh, providing second-level frequency regulation and short-term peak-shaving;

Hydrogen storage: 10 MW / 40 MWh, serving long-duration storage (scheduled for completion and grid connection in 2026).
