Caveats

  • Generation figures are net of plant use (station power), not gross generation.
  • The source file publishes megawatthours; every value here is that figure divided by 1000 to store gigawatthours, with no further rounding.
  • energy.net_generation and energy.net_generation_by_source cover 'Total Electric Power Industry' (all producer types: electric utilities, independent power producers and combined heat and power), not any single provider type.
  • energy.net_generation_by_source omits a source for a year when EIA collected no generation for it that year; the source does not publish an explicit zero row, so the set of categories present is not the same every year.
  • energy.hydro_share is not published by EIA; it is computed here as Hydroelectric Conventional generation divided by total net generation, times 100, rounded to one decimal place, and excludes pumped storage, which EIA reports as a separate energy source.
  • Hydroelectric output varies year to year with the water year (snowpack and runoff), so year-over-year changes in net generation and hydro_share reflect hydrology as much as demand or capacity.
  • All years through 2024 are EIA-final; the workbook's own sheet is named 'Net_Generation_1990-2024 Final' and nothing here is marked preliminary.
