The CO2e values
The figures for the different types come from "Comparison of Lifecycle Greenhouse Gas Emissions of Various Electricity Generation Sources" units are tonnes CO2e/GWH

Pumped Hydro415 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
Interconnectors273These 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)
Other273I do not currently have the break down of this
so have used the use the calculation (CCGT/2)+(((Nuclear+Biomass+Wind+Solar)/4)/2).
