Location: PL - Poland
This dataset represents the production of high voltage electricity and district heat in an average combined heat and power lignite power plant in Poland in 2012. 'Lignite' is used as representant for 'brown coal', which includes sub-bituminous coal and lignite according to the definition of the IEA electricity information 2014. (IEA. 2014. Electricity Information 2014. ISBN 978-92-64-21692-1. International Energy Agency (IEA), Paris Cedex (FR).)
All exchanges in this dataset except for emissions of SO2, NOx and particles are production-weighted averages of the figures in the datasets in ecoinvent version two, which are valid for the following 10 countries: AT, BA, CZ, DE, ES, FR, HU, PL, SI, SK. The exception values are production-weighted averages of version 2 countries and the new countries in version 3 (AU, CA, CL, ID, IN, KR, MX, MY, PE, RU, TH, TR, TW, TZ, UA, ZA)
Comments on the inventory data of emissions:
- for the assessment of main characteristics (sulphur and ash content of coal, efficiency of the plant) and CO2 a bottom-up approach has been used. It consists in the collection of information about single plants.
- Halogene emissions have been estimated on the basis of the content of the species in the country-specific coal input mix, assuming average retention rates.
- For CO and particle emissions average values for the former UCTE are included (Union for the Coordination of the Transmission of Electricity, since 2009 replaced by ENTSO-E European Network of Transmission System Operators for Electricity).
- The country specific emissions of N2O depend on the share of DeNOx. - Emissions of trace elements were calculated by means of a formula (CORINAIR) using the ash content in the country-specific coal input mix and average transfer coefficients for coal power plants, taking into account the share of DeSOx installed.
- Emission of uranium and thorium radioactive isotopes were assumed proportional to the corresponding element emitted with particles; the other non-gaseous radioactive isotopes of the uranium and thorium decay chain were assumed proportional to the emitted U-238 or Th-232.
- The emission of gaseous radon and K-40 are taken from the literature.

[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.
