This dataset represents the construction of a wind turbine with a capacity of 750kW for onshore use. The term "wind turbine" inludes moving parts such as nacelle, rotor, rotor blades, transition piece as well as fixed parts such as the tower and the foundation.
The LCI model is based on collected data from the Wind Energy Technocentre in Quebec, that estimated the bill of materials in the different parts ot the turbine. The NEG Micon 750kW/48 has been taken as reference technology for wind turbines with a capacity lower than 1MW.
Some missing data were completed by extrapolation from 2MW turbine dataset.
Parts of the wind turbine are the following:
- Rotor: Rotor blades, rotor hub, extender
- Nacelle: The nacelle consists of the nacelle cover, which includes generator, gear, main shaft, yaw system, flanges etc.
- Electronics
- Tower (steel)
- Foundation
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
