CO2 Emissions per kWh of Electricity Generated in France

RTE continuously provides an indicator of the carbon footprint of electricity generation in France, expressed in grammes of CO2 per kWh generated. The "real-time" indicators are based on telemetry readings and estimates. It is possible to simultaneously display data for one day up to 8 weeks.
 
 
 
 

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.

N.B.:

French Network  
sector Technology  
Gaz TAC 0,593
Co-geneneration 0,350
CCG 0,359
Other gasses 0,552
Fuel TAC 0,777
Co-geneneration0,459
Other fuels0,783
Coal Coal 0,956
Bioenergies Waste0,983
Biomass 0,983
Biogas 0,983

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 Calendrier

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).
