Also see reporting instructions for more information about steam load data: https://www.epa.gov/system/files/documents/2024-03/ecmps_emissions_reporting_instructions_0.pdf, found at https://www.epa.gov/power-sector/ecmps-reporting-instructions. It looks like the conversion from klb steam to MWh is approximately 0.3-0.35 MWh per...

Specifically, the old column format included `.NG.ALL-H`, but it looks like the new format is `E_BA_NG`

Also, there are two sources of data for LFG emission factors. One being the Electric Power Annual Table A-2, and one being table 2.4-4 in the EPA's AP-42 (https://www.epa.gov/sites/default/files/2020-10/documents/d02s04_0.pdf)

This issue is also relevant to SO2 factors

Also, EIA-923 collects a CHP Efficiency field. As per the EIA-923 [instructions](https://www.eia.gov/survey/form/eia_923/instructions.pdf): > CHP Plant Efficiency: If the CHP checkbox is “YES”, enter the efficiency of the combined heat and...

I have confirmed that the reported steam load data in CEMS is not necessarily related to CHP: https://github.com/singularity-energy/open-grid-emissions/issues/216

One paper that explores CHP allocation methods is https://ieeexplore.ieee.org/document/8352048/

Whenever we add new years of data, there are a few things we need to do: - Check whether the data to be downloaded uses the same url pattern as...

For now, we can take the following approach: - If a plant is assigned to a BA that retired prior to the current year, set its BA as missing so...

Currently, the EIA allocation process uses the separate fuel types when available, but when assigning fuel types to CEMS data using the power sector data crosswalk, this only includes fuel...
