en.Wedoany.com Reported - On June 24, the CSSC Technology Hami Yiwu Naomaohu 150MW Wind-Storage Integration Project successfully completed its reverse power transmission test and achieved full-capacity grid-connected power generation. This project is a park-level wind-storage demonstration project implemented by CSSC Technology in Xinjiang, following the Hami Shisanjianfang 1GW Wind-Storage Base. Leveraging self-developed wind-storage coordination technology and experience from Gobi desert project construction, it possesses both economic and ecological value, creating a replicable model for comprehensive energy development in sandy, Gobi, and barren areas.
Hardcore Technology Support
Setting a Benchmark for Gobi Wind-Storage Projects
Located in the Naomaohu area of Yiwu County, Hami City, the project has a total installed capacity of 150MW, all utilizing the self-developed H220-10MW customized onshore wind turbine. It is equipped with a 15MW/30MWh energy storage system, a 220kV step-up substation, and a 26-kilometer transmission line, forming a one-stop integrated solution of "large wind turbines + high-proportion energy storage + park-level consumption."
The project site has an average annual wind speed of 7.04 m/s at a hub height of 125 meters, indicating superior wind resources. After economic calculations for multiple turbine models, the H220-10MW onshore wind turbine, specifically developed by CSSC Technology for sandy, Gobi, and barren scenarios, was selected. This turbine is a representative product of the large-megawatt, low-cost technical route for onshore wind power. It features enhanced wind and sand resistance and temperature difference tolerance design, with excellent high and low voltage ride-through capabilities, suitable for the extreme climate of -40°C to 50°C in sandy, Gobi, and barren areas. It has been successively applied in several large wind power bases, including Huadian's Northern Tianshan Mountains, Balikun, and Jingneng's Ximeng UHV project.
The project is equipped with an independent self-developed wind-storage coordinated control system. The energy storage system achieves peak shaving and valley filling, smoothing power generation fluctuations, effectively controlling the project's curtailment rate within 15%. It stores surplus electricity for peak-shifting supply to park enterprises, enhancing clean energy consumption capacity.
The project construction phase coincided with the window period for wind power installation in Hami, facing multiple challenges such as a shortage of lifting equipment and strict controls on the transportation of large components like blades and towers across the Tianshan Mountains. The project team proactively coordinated lifting resources from multiple sources, simultaneously dispatched technical personnel to tower factories to supervise capacity improvement, optimized the scheduling process for nighttime large-component transportation, efficiently compensated for supply delays, and completed the installation of all turbines on schedule. This formed a comprehensive set of management experiences for new energy projects in remote Gobi areas, covering equipment supply assurance, large-component transportation, and cross-construction operations.
Multiple Benefits Highlighted
Empowering Regional Green and Low-Carbon Development
Leveraging the advantages of the CSSC Group's full industry chain, CSSC Technology has successively built three wind-storage integration projects in Hami: the Shisanjianfang 1GW large-scale wind-storage base, the Shisanjianfang 500MW project, and the Naomaohu 150MW park supporting project. The Shisanjianfang project, as the largest single wind-storage integration project in Xinjiang, completed the full technical verification of a million-kilowatt clean energy base. The Naomaohu project focuses on the low-carbon transformation needs of industrial parks, creating a standardized implementation model for small and medium-sized wind-storage projects. Technical achievements and construction experiences are shared among the projects, forming a development system with complementary scales and full scenario coverage.
After operation, the Naomaohu project is expected to output an average of 341 million kWh of clean electricity annually, with an equivalent annual utilization hours of 2,266 hours. It can save 109,300 tons of standard coal and reduce carbon dioxide emissions by 273,000 tons per year, significantly decreasing emissions of pollutants such as soot, sulfides, and nitrogen oxides. The project's green electricity is prioritized for supply to high-energy-consuming enterprises in the Yiwu Industrial Park, accelerating the low-carbon substitution of industrial energy use. The site is located in a Gobi area, avoiding the occupation of farmland, and is accompanied by windbreak and sand-fixation measures, balancing economic and environmental benefits and providing support for local green and low-carbon development.
In the next step, CSSC Technology will continue to deeply cultivate the northwest new energy market. Leveraging the accumulated experience from the construction and operation of the Hami wind-storage projects, it will continue to expand multi-energy integration projects combining wind, solar, hydrogen, and storage. By leveraging its integrated full-chain advantages in wind turbine R&D, EPC contracting, energy storage supporting, and smart O&M, it will help accelerate the construction of Xinjiang's new power system.
