ERCOT INR link to EIA Plant ID?

[edhenigin]

I was wondering if anyone's done the work to link ERCOT's INR IDs to EIA Plant IDs.

And/or your thoughts on the wisdom or desire for that linkage.

From what I can see, I don't think you can do that with any real confidence. I guess I'm partly wondering if there's a data source out there that would make it feasible.

I just did a manual test, focusing only on Travis County. Out of the 46 operating plants in September 2025 EIA-930M EIA-860M, was only able to find INRs in all of ERCOTs GIS files for 3 of them. Probably pointless.

I'm not familiar with ERCOT's INR IDs. Did you really mean the EIA-930M? Is there any EIA-930 data that has plant-level data? We've only worked with the hourly generation data.

I would think the EIA-860 would be the place to look for IDs. Also, if you have lat/lon for the ERCOT plants, you could probably do a spatial join on the lat/lon of the EIA plants and get a lot of matches.

oops I mean EIA-860M

I can't find any publication of lat-lon tied to ERCOT tracking, just the EIA-860 stuff
