"For example, if an organization uses 100 mWh per year of electricity and purchases 75 mWh of clean energy, the remaining 25 mWh would be assigned the locational emissions rate, such that the total market emissions would be 25% of the total locational emissions."
Not sure if this part is exactly what GHG protocol recommends in its guidance. The 25 MWh should be multiplied by Residual Mix Factor and not the average grid emission factor. What do you think?
In the US there's no residual mix factor, so you have to use the grid average. IMO, the grid average makes more sense anyway because the residual mix, as it's calculated, is only for resources interconnected at the transmission level, which is obviously a small portion of the overall resource mix when considering distributed energy resources.
