Usage Warnings
Some columns contain subtotals; use caution when choosing columns to aggregate.
Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.
Additional Details
Note that according to RUS, 'underbuild in overhead lines or joint runs in underground installations do not increase the number of line miles except for distribution underbuild on transmission poles. In such cases, distribution pole line miles would be increased by the number of underbuild miles involved.'
