PUDL Infrastructure Roadmap for 2021

A couple of weeks ago I attended TWEEDS 2020 virtually (like everything this year) and talked about Catalyst’s ongoing Public Utility Data Liberation (PUDL) project, and especially the challenges of getting a big pile of data into the hands of different kinds of users, using different tools for different purposes. It ended up sketching out a bit of a PUDL infrastructure roadmap for the next year, and so we thought it would be a good idea to write it up here too.

We’ll have a separate post looking at our 2021 data roadmap.

The US Energy Information Asymmetry

PUDL is all about addressing a big information asymmetry in the regulatory and legislative processes that affect the US energy system. Utilities have much more information about their own systems than policymakers and advocates typically do. As a result, regulators often defer to the utilities on technical & analytical points. Commercial data exists, but it’s expensive. We want to get enough data into the hands of other kinds of stakeholders that they can make credible quantitative arguments to regulators, and challenge unfounded assertions put forward by utilities.

Heat Rate Calculation for EIA Generators

Catalyst is pulling together an estimate of the marginal cost of electricity (MCOE) for every natural gas and coal fired power plant in the US whose data we can get our hands on. We’re using data from the EIA 923, EIA 860, and FERC Form 1 to do it.  Getting the heat rate right for each generator is an important part of this calculation, but a lot of the required data is… not perfect. Here’s how we’re working through it.
