Customer count 2. Energy sales (kwh for electrical utilities, therms for gas utilities.) ## Why 1. So Rewiring America and Switchbox can understand the details of the assignment algorithm 2. So we can use the summary stat comparison to see how accurate this assignment algorithm is, and the impact of any tweaks to this algorithm ## How * Compare electric utility customer residential customer counts and kWh sales to [EIA 861 data](https://catalystcoop-pudl.readthedocs.io/en/latest/data_sources/eia861.html), by joining on EIA id * Compare gas utility customer residential customer counts and therm sales to [EIA 176 data](https://catalystcoop-pudl.readthedocs.io/en/latest/data_sources/eia176.html), by joining on EIA id ## Deliverables * PDF write-up, posted as a comment on this issue
