On the one hand, I updated our parquet schema checks to be able to run on even the 5-billion row EQR transactions table. On the other hand, this just revealed that none of the primary keys FERC identifies in their data dictionary are actually unique.

Sorry but this isn't really true - the March solar export spike was due to the Chinese export tax rebate ending as the title mentions, the exports were down again in April and May. We do expect effects, but mostly longer term except in a very few markets.

Electricity affordability and cost drivers are big news these days, so we made a dashboard that lets you explore related FERC & EIA data in PUDL. It's not *simple* but the rate-base composition is pretty interesting. #EnergySky #DataViz #OpenData #Electricity data.catalyst.coop/dashboards/r...
A stacked bar chart showing the composition of the rate-base of US electric utilities over the last 30 years, based on FERC Form 1 data. There are many categories, but the transmission and distribution slices are quite large, and have been growing over time. Note these numbers are not adjusted for inflation.
