Hmm, maybe this is a "bug" or some intentional way this measurement is made, but when you view the carbon production over time, you can see that some low-carbon sources like wind & solar seem to vary in proportion to the energy being produced. So these aren't exactly zero-carbon because of production and maintenance and whatnot, but it's obviously very low. However, wouldn't this carbon production be annualised at a constant rate - solar power doesn't produce more carbon the brighter the sun shines (does it?) It makes sense that there's some lookup of X energy source being Y tons co2 per mwh, and this is probably correct when the vast majority of the co2 is coming from the fuel, and the construction + maintenance etc are a rounding error, but this wouldn't be the case for solar, wind, etc.
