Reference product: heat, district or industrial, other than natural gas [MJ]
Location: CZ - Czechia
This dataset represents the production of high voltage electricity and district heat in an average combined heat and power lignite power plant in Czech Republic 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 has been generated using the system model “Substitution, consequential, long-term". A system model describes how activity datasets are linked to form product systems. This consequential system model uses substitution (also known as "system expansion") to substitute by-product outputs. It includes only activities to the extent that they are expected to change in the long-term as a consequence of small-scale changes in demand, following a consequential approach, taking into account both constrained markets and technology constraints.
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)]
Lignite power plant input is a dataset which consists of a mix of 30% 100MW power plant and 70% 500MW power plant. The plants are used for basic load with 6000 hours of operation at full capacity per year. The plants are assumed to operate 200000 hours during its lifetime.
