v0.1.1
Summary of updates
This release (v0.1.1) patches several bugs that were affecting the quality of the data published in the initial release. A big thank you to user @ewezerek for bringing one of these bugs to our attention.
Consumed emission factors
Due to a mathematical error in the previous version of the code, the consumed emissions factors incorrectly accounted for the flow of electricity between regions, which was causing some consumed emissions factors to be reported as negative. We have fixed this error and also implemented validation checks to ensure that the published emissions factors are not negative. While fixing this bug, we also noticed a data quality issue with the EIA-930 input data for AZPS interchange with SRP prior to 6/1/2020, which has been manually corrected.
Impacted data: all carbon accounting data, certain regional power sector data
Sulfur Dioxide (SO2) emissions
Due to misunderstanding several of the assumptions for applying SO2 emissions factors, the SO2 emissions data derived from EIA-923 fuel consumption data were under-reported by several orders of magnitude. These calculations have been corrected, and the updated SO2 emissions totals have been validated as consistent with the SO2 emissions totals published in other data sources.
Impacted data: All SO2 emissions data for plants that don’t report SO2 emissions to CEMS (impacts all regional power sector and emissions accounting data)
Data Quality Metrics
This release adds NOx and SO2 data to the published data quality metrics, and adds information about the quality of the published CEMS data. Details on these updates can be found here.
