Attribute "other fossil fuels" to Oil for NYISO? #4969

Open potash opened 1 year ago

potash commented 1 year ago

Hovering over the section of the real-time fuel mix pie chart here shows that NYISO lumps its reporting of coal and oil into "other fossil fuels."

However, there is also zero coal capacity in NY. So I think that all of the "other fossil fuels" category can be attributed to oil (as opposed to ignoring this data which seems to be the case currently?), making the map a tiny bit more accurate for NY.

Thanks for reporting this! I have looked into the issue and we do parse and store the data in the unknown category so it's not ignored. However since the page does say it's either oil or coal and there is a zero coal capacity (would need to verify this to be sure) we can probably attribute it to oil instead of unknown.

I'll leave it open for now until we have had time to verify the coal capacity and made the changes to the parser if applicable.

There's this confirming shutdown of coal: https://www.nyiso.com/documents/20142/2248793/2020-RNAReport-Nov2020.pdf PDF pages 15 and 19

https://www.eia.gov/state/analysis.php?sid=NY also confirms this, final shut down in early 2020

Thanks for looking into this as well @jarek. With the above sources I feel confident enough that the "other fossil fuels" can be attributed to oil only. If anyone of you want to make a PR for it feel free to do so otherwise I'll do it myself in the coming days.

EDIT: This should probably only apply for data after april 2020 when the coal plant shut down.
