Rescuing Historical FERC Data

This week we discovered that decades worth of energy system data collected by the Federal Energy Regulatory Commission (FERC) had been removed from the agency’s website. They apparently have no plan to archive it or migrate it to another platform. We are attempting to obtain a bulk download of all this data so we can archive it alongside our other raw data sources on Zenodo.

This data records many financial, operational, and economic aspects of the US energy system. It is a unique and valuable resource for anyone trying to understand how public policy and market conditions have shaped our energy system over time. Simply deleting this data with no warning, no plan to archive it, or migrate it to another platform is completely unacceptable.

If you know someone within FERC who can help get us a copy of this data to archive publicly, please put us in touch: hello@catalyst.coop

PUDL v0.5.0: 2020 and Beyond

It’s been almost a month since we pushed out our first actual quarterly software and data release: PUDL v0.5.0! The main impetus for this release was to get the final annual 2020 data integrated for the FERC and EIA datasets we process. We also pulled in the EIA 860 data for 2001-2003, which is only available as DBF files, rather than Excel spreadsheets. This means we’ve got coverage going back to 2001 for all of our data now! Twenty years! We don’t have 100% coverage of all of the data contained in those datasets yet, but we’re getting closer.

Beyond simply updating the data, we’ve also been making some significant changes to how our ETL pipeline works under the hood. This includes how we store metadata, how we generate the database schema, and what outputs we’re generating. The release notes contain more details on the code changes, so here I want to talk a little bit more about why, and where we are hopefully headed.

If you just want to download the new data release and start working with it, it’s up here on Zenodo. The same data for FERC 1 and EIA 860/923 can also be found in our Datasette instance at https://data.catalyst.coop

New PUDL Software & Data Release: v0.4.0

In August we put out a new PUDL software and data release for the first time in 18 months. We had a lot of client work, and kept putting off doing the release, so a whole lot of changes accumulated. Some highlights, mostly based on the continuously updated release notes in our documentation:

New Data Coverage

  • EIA Form 860 added coverage for 2004-2008, as well as 2019.
  • EIA Form 860m has been integrated (through Nov 2020). Note that it only adds up-to-date information about generators (especially their operational status).
  • EIA Form 923 added the 2001-2008 data, as well as 2019.
  • EPA CEMS Hourly Emissions covering 2019-2020.
  • FERC Form 714 covering 2006-2019, but only the table of hourly electricity demand by planning area. This data is still in beta and the data hasn’t been integrated into the core SQLite database, but you can process it on the fly if you want to work with it in Pandas.
  • EIA Form 861 for 2001-2019. Similar to the FERC Form 714, this ETL runs on the fly and the outputs aren’t integrated into the database yet, but it’s available for experimental use.
  • US Census Demographic Profile 1 (DP1) for 2010. This is a separate SQLite database, generated from a US Census Geodatabase, which includes census tract, county, and state level demographic information, as well as spatial boundaries of those jurisdictions.
