Hi Don,
I'm trying to compare yearly changes of the anticipated grid CI (specifically BC) in 5.02c. I'm sourcing the grid CI value from cell C55 on the Elec Emissions sheet, but that number seems high relative to the NIR 2023 published data. For example, running the BC grid in 2025 appears to give an electricity CI of 42.7 gCO2e/kWh but the NIR uses a value of 18. This makes me think I'm not looking at the correct cell for grid CI - is there somewhere I can see the overall value of the grid mix I supply from the Input B4?
Also, my understanding is GHGenius uses the CER's Energy Future Report (I assume also the 2023 version) - could you please confirm?
Thank you.

You are looking at the right cell in 5.02 but not the right comparator. The NIR does not report the lifecycle CI for electricity. It excludes any fuel production emissions (small for BC) and all methane emissions. from hydroelectric reservoirs.
The GHGenius value is very close to the value that ECCC has in the CFR database and those two have equivalent system boundaries.
It is the 2021 Energy Futures report that is used in 5.02.

Thank you for the quick reply! Just to clarify, when I pull the ECCC BC grid value (not temporally bound) I get 30.26 gCO2e/kWh as compared to GHGenius' 43.4 g/kWh in 2025. Are you able to expand on why the values are different beyond using a forward-facing forecast in GHGenius as opposed to ECCC's NIR stagnant value?

The BC Grid CI in the ECCC CFR database is 39 g CO2eq/kwh. That is based on the 2021 electricity mix.
I am not sure where the 30.26 g/kWh value that you mention is found.
