Public Utility Data Liberation Project (PUDL) Data Release

v2025.10.0 (2025-10-14)

This is a regular monthly data release, primarily intended to ensure that PUDL has the most up-to-date EIA-860M data. It also happens to include final EIA-860 data for 2024, and some newly integrated EIA-923 financial data and PHMSA natural gas data. See below for details.

Expanded Data Coverage

EIA-860

• Updated EIA-860 with final release data from 2024. See issue #4616 and PR #4617.

EIA-860M

• Updated EIA-860M monthly generator report with newly published data for August of 2025. See issue #4639 and PR #4638.

New Data

PHMSA

• Added eight transformed table containing annual data from PHMSA natural gas distributors from 1970 to the present. Note that these containing mostly numeric values are named as _core - indicating that these tables have not been fully cleaned and validated. We’ve published these tables to make the 50+ years of PHMSA data we’ve extracted and mapped available for others to use and for contributors to more easily improve incrementally. See #3770 and #4005.

• The first cleaned table, core_phmsagas__distribution_operators has been added to our PUDL database. Thanks to @seeess1 for all of your work on this!

EIA 923

• Thanks to contributions from @alexclippinger, we’ve added cleaned EIA923 Schedule 8B Financial Information to the PUDL database as _core_eia923__yearly_byproduct_expenses_and_revenues. Once harvested, this table will be replaced with a well-normalized version of the same data, but it is being published in this form until then. See #4099 and #2448, and #4636.

Documentation

• Added data source pages for:

  • Population Estimates Program's (PEP) Federal Information Processing Series (FIPS) Codes; see issue #4375 and PR #4622.

  • U.S. Securities and Exchange Commission (SEC) Form 10-K; see issue #4329, #4347 and PR #4562.

New Data Tests & Data Validations

• After investigating some modest discrepancies between our imputed hourly electricity demand and prior work by @truggles & @awongel, we’re removing the “EXPERIMENTAL” warning label that we had on those tables. See our discussion about the imputation results in the PUDL Examples repo. The associated notebook is available on Kaggle

  This relates to the PUDL imputed demand values in following tables:

  • out_eia930__hourly_operations

  • out_eia930__hourly_subregion_demand

  • out_eia930__hourly_aggregated_demand

Deprecations

• We have finally shut down our long-suffering Datasette deployment, but are still working on achieiving feature parity in the new PUDL Data Viewer. We have an epic tracking our progress. See issue #4481 and PR #4605 for the removal of Datasette references within the main PUDL repo.
