Location: CA-QC - Canada, Québec
This dataset represents the construction of a run-of-river hydropower power plant in Quebec. This dataset is based on study on the production, transmission and distribution of electricity in Quebec. It represents an average of all the run-of-river power plants that belong to Hydro-Quebec, which is the main electricity provider in the region (about 95% of the total electricity produced). The inventory is based on a sample of 42 run-of-river power plants that combine for 13787MW, with different capacity (from 1800 MW to 4MW) and all the dams and derivations that were built to ensure the operation of the plants. Lifetime is assumed to be 100 years for the plant. The data refers to plant construction of a mix of types of dams built between 1910 and 2014, therefore they might not be representative for an individual type of hydropower power plant. Lifetime is assumed to be 100 years for the plant and 50 for most of the equipments included (turbine-generator, valves, cranes, etc.)
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
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.
