GB Electricity National Grid CO2e Output per Production Type

last update GMT

    The CO2e values
    The figures for the different types come from "IPCC Annexe 3" units are tonnes CO2e/GWH
    Fuel TypeValuesource
    CCGT490Median value from above publication
    Nuclear12Median value from above publication
    Biomass505Average of the 2 Biomas Median values from above publication
    Coal820Median value from above publication
    Wind11Median value from above publication
    Solar48Median value from above publication
    Oil733Value from "Comparison of Lifecycle Greenhouse Gas Emissions of Various Electricity Generation Sources"
    OCGT588Median value from above publication for ccgt + 20%
    HydroElectric24Median value from above publication
    Pumped Hydro477 Assumes that the plant produces 70% of the energy needed to pump the water to the higher resevoir.
    The co2 for this will come from other fuels so a calculation is made with CCGT being 50% of the co2 and the rest being split between Nuclear,Biomass,Wind and Solar.
    TO this figure is added the Co2 of a Non Pumped HydroElectrical.
    (( 100/70 )* (( CCGT/2 )+((( Nuclear +Biomass +Wind +Solar )/4)/2))) +Hydroelectric
    Interconnectors317These use the calculation ( CCGT/2 ) +((( Nuclear +Biomass +Wind+Solar )/4)/2).
    There is likely scope to attribute different values to each interconnector as the mix of fuels will differ
    (ie The French Interconnector will use a high percentage of Nuclear)
    Only interconnectors importing are added to the total as the co2e produced for exporting is already accounted for under each fuel.
    Other317I do not currently have the break down of this
    so have used the use the calculation (CCGT/2) +((( Nuclear +Biomass +Wind +Solar) /4) /2).

    If you have an alternative source for CO2e information please let me know.
