Recent Releases of The Public Utility Data Liberation Project

The Public Utility Data Liberation Project - PUDL v2025.2.0

This is our regular quarterly release for 2025Q1. It includes updates to all the datasets that are published with quarterly or higher frequency, plus initial versions of a few new data sources that have been in the works for a while.

One major change this quarter is that we are now publishing all processed PUDL data as Apache Parquet files, alongside our existing SQLite databases. See Data Access for more on how to access these outputs.

Some potentially breaking changes to be aware of:

Many thanks to the organizations who make these regular updates possible! Especially GridLab, RMI, and the ZERO Lab at Princeton University. If you rely on PUDL and would like to help ensure that the data keeps flowing, please consider joining them as a PUDL Sustainer, as we are still fundraising for 2025.

See the v2025.2.0 release notes in our documentation for more details.

The Public Utility Data Liberation Project - PUDL 0.4.0

The Public Utility Data Liberation Project - v0.3.2: Integration of EIA 860 data for 2009-2010

The primary changes in this release:

  • The 2009-2010 data for EIA 860 have been integrated, including updates
    to the data validation test cases.
  • Output tables are more uniform and less restrictive in what they
    include, no longer requiring PUDL Plant & Utility IDs in some tables.
  • This release was used to compile v1.1.0 of the PUDL Data Release, which is archived at Zenodo under this DOI: https://doi.org/10.5281/zenodo.3672068

With this release, the EIA 860 & 923 data now (finally!) cover the same span of time. We do not anticipate integrating any older EIA 860 or 923 data at this time.
