CO2 Emissions per kWh of Electricity Generated in France
How are these data calculated?
RTE supplies a continuous indicator of carbon emissions generated by electricity production in France, expressed in grams of CO2 per kWh produced.
Definitive consolidated data:
This indicator is calculated for each type of technology using two elements:
- The thermal emission factor of g/CO2 per kWh given by the Centre Interprofessionnel Technique d’Etude de la Pollution Atmosphérique (CITEPA) [The Inter-professional Technical Centre for Studies on Air Pollution],
- An estimation by RTE of the output between thermal kWh and electric kWh.
A pro rata of the MWh produced by technology is then carried out to calculate the indicator per sector.
- CITEPA emissions factors are used by ENTSO-E, the European Association of Transport Network Managers, in its publications. These values are also used by the International Energy Agency (IEA) for its own publications.
- Values used for this indicator can be accessed on the RTE éCO2mix site at the following address: http://www.rte-france.com/fr/eco2mix/eco2mix-co2
Real time data
We currently do not have data broken down per technology in real time. We have thus calculated a mean coefficient per combustible.
The contribution of each production sector to CO2emissions is given below:
- 0.96 t/MWh for coal groups,
- 0.80 t/MWh for fuel groups,
- 0.36 t/MWh for gas groups,
- 0.98 t/MWh for bioenergies,
These values will be regularly updated to reflect technical changes in production means as well as the share of different technologies within a sector.
The indicator displayed illustrates only CO2 emissions generated by consumption of the primary combustible of production power stations in France. CO2 emissions calculated by RTE do not take into account carbon emissions generated during construction of production means, or carbon emissions generated during the extraction / transformation / or transport cycle of combustibles employed. Lastly, CO2 emissions per kWh in France do not take into account energy exchanges with imports or exports of electricity.
About historical data
Historical data records are adjusted twice after they are first published:
- During the following month, indicators are consolidated ("consolidated data", shown in green, based on the available metering data).
- During the first half of the following year, indicators are finalised ("final data", shown in blue, based on all metering data).
