Sany New Energy's first hybrid tower EPC - Yucheng project is connected to the grid at full capacity

On May 20, 2025, with the successful connection of the last wind turbine to the grid, the Yucheng 48MW wind power project will be connected to the grid at full capacity. The project uses 8 SI-200625 wind turbines with a hub height of 170m, with an estimated annual power generation capacity of 139 million kWh, which can save 42,000 tons of standard coal and reduce carbon dioxide emissions by 110,000 tons per year, injecting strong impetus into the transformation of the energy structure in Dezhou.

The Yucheng project is a benchmark project for ultra-high hybrid towers carefully built by Sany New Energy, a wholly-owned subsidiary of Sany Renewable Energy. With the full support of the company, the project team innovated the process and construction method, strictly controlled the quality and safety, and successfully completed the hoisting task of 8 ultra-high mixed towers, all of which reached the industry-leading level. Among them, the verticality of the 170m high mixing tower is strictly controlled within 10mm, breaking the industry record. In addition, it also avoids common problems in the industry such as easy water leakage and easy cracking; The aesthetic design scheme of the new mixed tower adopted gives the steel giant a sense of rhythm that blends with the land of Qilu. Through the innovation of the ultra-high hybrid tower construction system (design-manufacturing-construction-operation and maintenance), we pursue high quality and new technologies to lay the foundation for the sustainable development of the industry. Relying on this project, 4 invention patents and 11 utility model patents have been authorized, and it has won the first prize of Hunan Renewable Energy Science and Technology Progress Award, and the R&D results have been incorporated into the national standard "Design Standards for Onshore Wind Farms" GB51096 revised.

Since the start of construction in September 2024, the project team has faced multiple challenges such as technological innovation, extreme weather, complex terrain, and large-scale transportation, and achieved grid connection from construction to full capacity in only 9 months without internal experience to follow. Through the mode of "dynamic construction scheduling + modular equipment transportation", the industry-leading speed of hoisting the whole machine of 5 wind turbines in a single month is realized, and the mixed tower hoisting process independently developed by the project breaks the record of the same type of project with the construction efficiency of 11 rings in a single day, showing the "Sany speed" and "Sany accuracy" of efficient collaboration.

Looking back at the mid-term node of the "dual carbon" goal, the significance of the Yucheng project is just like the metaphor of the mixed tower: the concrete symbolizes the solid commitment to take root in the earth, and the rotating impeller shows the innovative passion for looking up at the starry sky. In this marathon of energy revolution, Sany New Energy is taking benchmark projects as the guidepost to write the evolution theory from "scale development" to "standard leading"; In the future, more high-quality projects will be built to help the country's energy transition and sustainable development.
