It seems that based on [this comment](https://github.com/jdechalendar/gridemissions/issues/8#issuecomment-1207360498), this method was implemented in `gridemissions` out of convenience rather than necessity, so it should be possible to update that repo as part...
So it seems like using `GGL = Losses / (Disposition - Resales)` leads to a national average GGL value of 5.4%, but it also leads to really high values in...
Currently, these regression values are not currently used in the data pipeline, although the linear model seems to fit the data well (r2-adj > 0.9). See [this documentation](https://singularity-docs.stoplight.io/docs/open-grid-emissions-docs/branches/v0.1.0/gross_to_net-background-of-gross-generation-and-net-generation) for background...
Picking this PR back up on 11/22/23 after months of inactivity. At this point, just merged the most recent development branch in and did a test run of the pipeline...
It looks like this issue is causing a large discrepancy in SO2 emissions between OGE and eGRID.
Our NOx and SO2 calculation methodology implemented in https://github.com/singularity-energy/hourly-egrid/pull/152 currently assumed zero NOx and SO2 emissions from natural gas consuming fuel cells. We should research and refine this assumption.
As part of https://github.com/singularity-energy/open-grid-emissions/pull/273, we started using these default prime-mover based factors as the backstop gross to net generation ratio if no other methods worked. However, there are several ways...
One simple fix could be to use non-missing data to calculate a unit-specific average nox rate and use that to fill in the missing hours
The eGRID technical guide also notes that for geothermal emissions: > The three pollutants’ [CO2, SO2, NOx] emission factors, obtained from a 2007 Geothermal Energy Association environmental guide (GEA, 2007),...
IPCC Factors come from Chapter 2: https://www.ipcc-nggip.iges.or.jp/public/2006gl/pdf/2_Volume2/V2_2_Ch2_Stationary_Combustion.pdf, Table 2.2 To convert from (kg of greenhouse gas per TJ on a Net Calorific Basis) to lb/mmbtu, you must multiply by 0.002326
