Project description

A pioneering approach to wind turbine tower design, this 160M prestressed concrete filled steel tubular (CFST) lattice tower brings innovative engineering solutions to the renewable energy industry. Its three-section configuration reduced material use, speeded up construction and enabled high-hub-height turbines to operate efficiently in areas with limited wind resources. Small, independent foundations conserve agricultural land, while the project also serves as a showcase for knowledge sharing and the wider application of this technology.

Judge’s comments

A breakthrough in wind energy engineering, this use of a prestressed concrete filled steel tubular lattice tower allows the turbines to operate efficiently in low-wind areas. Its steel concrete composite transition and lightweight lattice form deliver exceptional strength, durability, and material efficiency. Independent foundations reduce land impact, while rapid construction methods and a commitment to sharing knowledge highlight the project’s potential for broad application.
