Generally, our linear equation for regressing gross to net generation seems to fit the data very well (in some cases almost exactly). However, in the future we may want to...

We do not currently calculate nonbaseload emission rates, which are a type of marginal emission factor estimate. In eGRID, nonbaseload emission rates are calculated based on the plant-level capacity factor....

We currently exclude Puerto Rico data, although this data was added to eGRID starting with eGRID 2019. The challenge is that Puerto Rico data is only reported at the monthly...

For fossil generation for which we are missing EIA-930 profile data, we are currently assuming a flat profile (essentially using the monthly average value). However, in some cases, it would...
