Thanks to everyone who has helped make this project a reality!

Open Source Contributions

We’ve been lucky to have some financial support for PUDL over the last 3+ years, but a lot of the work has still been done on a volunteer basis, both by members of Catalyst Cooperative and open source contributors, including:

  • Karl Dunkle Werner, a PhD student at UC Berkeley, who did a lot of the integration work for EPA CEMS Hourly.

  • Greg Schivley, a recently minted PhD from Carnegie Mellon University, who has pointed us at lots of great open data resources, and integrated the EPA IPM data.

  • Priya Donti, a PhD student at Carnegie Mellon University, for user experience and documentation feedback.

  • Josh Rhodes, Brianna Cote, and Vibrant Clean Energy for submitting Github issues and offering valuable user feedback.

Grant Funding

The Alfred P. Sloan Foundation Energy & Environment Program has funded one year of concerted work on PUDL aimed at serving the academic research community (May 2019 - April 2020). Many thanks to Will Driscoll for providing feedback on and edits to our Sloan proposal.

The PUDL project has also received support from The Flora Family Foundation to make the processed data available in Published Data Packages.


We wouldn’t be here today without a long list of partners who have helped us along the way.

We’re thankful for the opportunity to participate as a pilot project in the Frictionless Data Reproducible Research program of the Open Knowledge Foundation. Open Knowledge also supported Catalyst to attend CSV,Conf,v4 in Portland, Oregon.

Our initial 2017 work on PUDL was done as part of a project to enable refinancing and early retirement of uneconomic coal plants, in collaboration with The Climate Policy Initiative Climate Finance Program. (See these white papers for some of the results.)

The EU based Open Energy Modeling Initiative and Open Power System Data projects have taught us a lot about how to wrangle this data for research purposes, and the importance of the legal and licensing dimension of the work.

Thanks to Matt Wassen and Jeff Deal at Appalachian Voices for giving us a copy of their archive of FERC Form 1 data that’s no longer available online.

Clean Energy Action in Boulder, Colorado gave several of us our first chance to get paid to do energy policy and data analysis work, organizing around Xcel Energy’s Colorado coal plants.

The Rocky Mountain Farmers Union and their Cooperative Development Center helped us incorporate as a worker cooperative in Colorado, and continue to offer us affordable legal support.
