Electricity generation by source
Annual net electricity generation by state, provider type and energy source, compiled by EIA from the EIA-923 Power Plant Operations Report and predecessor forms EIA-906 and EIA-920.

Measures
| Measure | What it measures | Unit |
|---|---|---|
| Net electricity generation | Total net electricity generation from all producers and all energy sources, for a calendar year. | gwh |
| Net electricity generation by energy source | Net electricity generation from all producers, broken out by energy source, for a calendar year. Idaho only. | gwh |
| Hydroelectric share of net generation | Conventional hydroelectric net generation as a percentage of Idaho's total net generation from all sources, for a calendar year. Computed by the puller, not published directly by EIA. | percent |
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.
