Tools for producing high-quality hourly generation and emissions data for U.S. electric grids
In the EIA data, only a single official balancing authority is associated with Hawaii. However, according to [this 2016 report](http://energy.hawaii.gov/wp-content/uploads/2011/08/FF_Nov2016.pdf) from the Hawaii state energy office, "Each of Hawaii’s six...
Generally, plants report data to EIA-923 for all of their parts at a single frequency: monthly data or annual data. However, certain plants appear to report some of their data...
During peer-review of the hourly shaping methodology, a question was raised about whether the assumption behind the partial cems shaping methodology is robust (namely that all units within a subplant...
The SO2 emission factor used by eGRID for SUB coal is 35\*S, while the emission factor for BIT coal is 38\*S for all boiler firing types (see Table C-3 of...
Some generators report fuel consumption data to both EIA-923 and to CEMS, and these numbers are not always consistent with each other. Currently, we trust the CEMS data over the...
Related to LFG emissions factors and issue #69 and #150: eGRID uses two sources of data for their SO2 emisisons factors: EPA's AP-42 document, and the EIA electric power annual...
Although final, validated EIA form data is typically not available until the autumn following the end of each year, the EIA does publish preliminary, monthly files on only a several...
There is interest among some stakeholders in marginal emissions estimates being included in the OGE results. There are many different methods for estimating marginal emissions, so one value add that...
Particulate matter emissions could be added to the OGEI data. It appears that doing so would require integrating data from the national emissions inventory (NEI). Background information can be found...
Zooming in on the eia930 profile for nuclear, I noticed that the nuclear profile seems to be pretty variable:  However, looking at the reported EIA-930 data for nuclear in...
