This dataset represents the production of high voltage electricity at a grid-connected oil power plant with a capacity of 500 MW. This activity is only used in the consequential version of the database; currently, oil power plants are not used for power generation in this country, but they are supposed to contribute to capacity replacement/expansion until 2030.
Emissions are in general calculated/estimated based on the fuel oil type S, European quality. This dataset has been built on the basis of oil electricity production datasets in version 2 of the ecoinvent database which were elaborated by N. Jungbluth 2007 (see main publication in modelling and administrative). The values and emissions are a weighted average of emissions in all datasets in version 2 (which are considered as the global values) multiplied with an efficiency scaling factor. The datasets in version 2 were valid for the following countries: AT, BE, BR, GR, CN, CS, CZ, DE, DK, ES, FI, FR, GB, GR, HR, HU, IE, IT, JP, MK, NL, NO, PT, PL, SE, SI, SK. Weighting was made with electricity production data in those countries based on IEA/OECD 2010. The weighted averages are taken as global values and then scaled with a factor derived from the comparison of the global average efficiency and the efficiency valid for this dataset in order to account for a higher or lower fuel input for the production of 1 kWh, respectively. Nothing else than the efficiency has been adjusted in this dataset; besides that no new data collection has taken place
Comments:
- sulfur content of the oil is not adapted to local/average conditions.
- CO2 emissions are presented for the combustion and for the flue gas treatment
- Extensive comments on emissions can be found in Jungbluth 2007, on which this dataset is based on.
Emissions to the water are from flue gas treatment. Most of these data come from two power plants in Portugal (EDP 2001) and data from Slowakia

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.
