For nuclear power plants, the conversion efficiency from nuclear heat shall be assumed to be 33 % or data provided by Eurostat or a similar, accredited source.
No fuels are associated with electricity production from renewables that include hydro, solar, wind and geothermal.
The emissions from the construction and decommissioning and waste management of electricity producing facilities are not considered.
Thus, the carbon equivalent emissions associated with the renewable electricity (wind, solar, hydro and geothermal) production are considered to be equal to zero.
The CO2 equivalent emissions from gross electricity production shall include upstream emissions from JEC WTW v5 (Prussi et al, 2020) listed in Table 3 and the default emission factors for stationary combustion from IPCC Guidelines for National Greenhouse Gas Inventories (IPCC 2006) listed in Tables 1 and 2.
The upstream emissions for supplying the fuel used shall be calculated applying the JEC WTW v5 upstream emission factors (Prussi et al, 2020).
The calculation of the carbon intensity of electricity shall be done following the formula: k
egross prod ¼ ∑i¼1 ðci – ups þ ci – comb Þ×Bi where: egross_prod =
2
CO equivalent emissions ½gCO2eq �
ci – ups =
upstream CO2 equivalent emission factors
ci – comb =
� � gCO2eq MJ
CO2 equivalent emission factors from fuels combustion
Bi =
fuel consumption for electricity generation ½MJ�
i ¼ 1…k =
fuels used for electricity production
� � gCO2eq MJ
The amount of net electricity production is determined by the gross electricity production, own electricity consumption in the power plant and the electricity losses in pump storage.
Enet 1⁄4 Egross – Eown – Epump where: Enet =
net electricity production ½MJ�
Egross =
gross electricity production ½MJ�
Eown =
own internal electricity consumption in power plant ½MJ�
Epump =
electricity for pumping ½MJ�
The carbon intensity of net produced electricity shall be the total gross GHG emissions for producing or using the net electricity: CI ¼
egross prod Enet
� � gCO2eq where: CI = CO2 equivalent emissions from electricity production MJ
Electricity production and fuel consumption data Data on electricity production and fuel consumption shall be sourced from IEA Data and statistics that provides data on energy balances and electricity produced using various fuels, e.g. from IEA website, Data and Statistic section (‘Energy Statistics Data Browser’) (6).
