Reference product: wind turbine, 4.5MW, onshore [unit]
Location: GLO - Global
This dataset represents the construction of a wind turbine with a capacity of 4.5MW 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.
Reference technology for this wind turbine is an Enercon E-112 turbine. The tower is made of reinforced concrete, a relatively new technology. LCI data are based on (Chataignere & Le Boulch 2003), supplemented with some own assumptions and adapted to the ecoinvent background database for this study. Parts of the wind turbine are the following:
- Rotor: Rotor blades (fibre-glass reinforced plastics), rotor hub, extender
- Nacelle (gearbox, generator, shaft and others)
Data are very rough since no real data were available for the tower and foundations mass balance, and since the detailed composition of the nacelle, blades and connection to the grid is derived from an Enercon E-66 1.5MW wind turbine.
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-models-in-ecoinvent-3.html)]
Technology: Enercon E-112 4.5MW wind turbine. This special type of wind turbine is not on the market any more, but the technology can still be taken as a good reference for wind turbines with a capacity of >3 MW built today.
