Caveats

  • Retail price is revenue divided by sales, expressed in cents per kilowatthour; for 2010-2024 EIA publishes this ratio directly, and for 1990-2009 the puller computes it the same way from EIA's own revenue and sales figures because that older file has no direct total-price column.
  • The source publishes sales in megawatthours; every gwh value here is that figure divided by 1000, with no further rounding. Revenue and price are stored as published (or as computed above), with no unit conversion.
  • energy.retail_sales (Idaho, all years) includes Idaho's 'Other' sector sales, which EIA collected from 1990-2002 (schools, street lighting and similar non-standard loads); those Other-sector sales are folded into the total but are not broken out as a category in energy.retail_sales_by_sector, which tracks only Residential, Commercial, Industrial and Transportation.
  • energy.retail_sales_by_sector has no Transportation observation for Idaho before 2003: EIA did not collect a Transportation sector for any state until 2003, replacing the Other sector it had collected through 2002.
  • Figures cover the 'Total Electric Industry' (all provider types combined: full-service, energy-only, delivery-only and competitive), not any single provider type.
  • All years through 2024 are EIA-final; nothing here is marked preliminary.
