PUDL v2025.9.1 is available

[zaneselvans]

This is a monthly release primarily focused on updating the EIA-860M, with other incremental changes coming along for the ride. Please drop a comment here or open a new discussion / issue if you find anything wrong with the release!

Things to be aware of

• User @mfripp identified a bug in how we were constructing detailed utility asset/liability and income/expense tables from FERC Form 1. This has been partially addressed, but the fix needs to be applied to a couple of additional tables. See Remove other rare non-total dimension's for out_ferc1__detailed* tables #4593.
• We are now producing GeoParquet outputs for tables that contain spatial data. This is a great new feature! But also potentially a breaking change, depending on what tools you’ve been using to read our Parquet outputs. GeoPandas and DuckDB’s spatial extension both work well.

For more details

• Check out the PUDL data access documentation for instructions on how to get the data.
• You can find it archived on Zenodo
