Since 2025 was the first year of funding our PUDL through contributions from sustaining members, we decided to write an annual report summarizing how it went in terms of the finances, the technical work, and some usage & impact metrics:

https://catalyst.coop/2026/02/20/2025-pudl-annual-report/

It also lays out the work plan and budget for 2026, and highlights how outside grant, client, and internal funds helped us improve and expand PUDL over the year, which increased the impact of contributions from our sustaining members. We hope the report makes it clear that the resources you entrusted us with were put to good use, and maybe even inspires you to keep supporting PUDL in 2026.

This is the first time we've done a report like this, so please let us know if you have any feedback or questions. You can email the PUDL maintainers at [email protected], hit us up on social media, start a GitHub Discussion, or respond right here on OpenCollective.

Thank you for supporting open data, open source software, our worker cooperative, and the transition away from fossil fuels!
