This dataset represents the production of high voltage electricity at onshore grid-connected wind power plants with a capacity between 1 (excluded) and 3 (included) MW in China - Shaanxi in 2012. It includes operation and maintenance expenditures as well as infrastructure inputs. Wind load hours have been adapted to local conditions (see parameters).
At the moment, the class of onshore 1-3MW wind turbines is approximated with a 2 MW onshore wind turbine consisting of the infrastructure datasets for the 'wind turbine construction' and the 'network connection construction'. The wind turbine's parts are defined to be everything except for the network connection, i.e. rotor, nacelle, tower, and foundation.
According to The Wind Power Database (2014), total installed wind capacity on-and offshore in China - Shaanxi in the end of 2014 amounted to 65268.61 MW. Out of it, 1.9% were installed offshore, which are modelled with a 2 MW wind turbine. Percentages of the three onshore wind power plant classes modelled in ecoinvent referring to the total installed capacity (725 windfarms by 12/2014): <1MW 15.5%; 1-3MW 44.8%; >3MW 37.8% [Retreived from The Wind Power. 2014. Wind power and wind farms database. www.thewindpower.net, Status December 2014]. Values are valid for TOTAL China, not for this specific province. The offshore plants are located in the provinces Jiangsu, Liaoning, Shanghai, Guangdong and Shandong.
[This dataset is meant to replace the following datasets:]
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.
