Description
This dataset represents the foundation construction and equipment installation for a single onshore wind turbine unit with a rated power of >=4, <5 MW. The process includes the construction and installation of wind turbine foundations, main transformers, array cables, and export cables. It is assumed that all construction materials and equipment are processed and installed at the wind farm. During the construction and installation stage, the main material inputs include concrete, steel, copper, aluminum, and resin, while energy consumption primarily consists of electricity used for construction and installation activities. Land occupation associated with wind farm construction is also considered. In the decommissioning and end-of-life treatment stage, it is assumed that metallic materials, including steel, iron, aluminum, and copper, are recovered at a rate of 90%. Materials such as resin are treated by incineration, while other materials are disposed of via landfilling. The data are primarily derived from publicly available literature and represent the average conditions of foundation construction and equipment installation for onshore wind turbines in China.
Activity Description
The process boundary involves raw material preparation, on-site construction and installation, as well as dismantling, recycling, and disposal phases, but excludes the operation and maintenance phase.

The infrastructure required for wind electricity generation and grid connection mainly includes wind turbine foundations, main transformers, array cables, and export cables. It is assumed that all construction materials and equipment are processed and installed at the wind farm. During the construction and installation stage, the main material inputs include concrete, steel, copper, aluminum, and resin, while energy consumption primarily consists of electricity used for construction and installation activities.
