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...
eGRID reports mercury (Hg) emissions, although the technical guide notes that: > However, while electric generating units started to report mercury data to CAMD’s Power Sector Emissions Data in 2015,...
The eGRID2020 technical guide notes that: > The emission factors are primarily from the default CO2 emission factors from the EPA Mandatory Reporting of Greenhouse Gases Final Rule (EPA, 2009,...
The eGRID2020 technical guide notes: > The CO2 emissions for units with a fuel cell prime mover are also assumed to be zero. However, as noted by several sources, fuel...
The eGRID technical guide mentions digester gas (DG) several times, although this energy source code does not seem to appear in any static tables or EIA data. - [ ]...
The eGRID 2020 technical guide notes: > Emissions adjustments for NOx , SO2 , CH4 , and N2O emissions are only conducted for landfill gas in eGRID. This adjustment is...
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...
Our published carbon accounting emission factors do not yet consider transmission losses as part of the calculation, which would account for losses between the points of generation and points of...
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...
