Caveats

  • Covers 2015-2025: 2014 and earlier ship in the legacy Excel binary (.xls) format, which this puller does not read.
  • A utility's price is its average revenue per unit sold (revenue divided by sales), not its tariff rate schedule; a residential customer's actual rate depends on usage tier, time of use and any riders.
  • A utility that files the abbreviated 861S short form (most of Idaho's smaller municipal and cooperative systems) reports one undivided total revenue, sales and customer count, with no residential, commercial or industrial split. No such split is estimated for it: this dataset's two measures below need a reported sector, so a short-form utility appears in the records table only, with its sector figures left blank.
  • EIA's own 'Adjustment' reconciling entry (Utility Number 99999) is excluded; it is a balancing-authority-level correction, not a utility.
  • Only Schedule 4 Part A (full-service, bundled) rows are kept; no Idaho utility reports a Part B, C or D (energy-only, delivery-only or power-marketer) row in this span.
