Compared with other states
Every state is compared on hydropower share of electricity use from the U.S. Energy Information Administration: Conventional hydroelectric generation inside the state as a percent of the electricity sold at retail in the state in the same calendar year, both from the EIA. Where EIA's by-source series is carried (Idaho and the nation) the hydro figure is read from it; for other states it is the hydro share of net generation times net generation. In-state hydro can exceed use, as it does in Washington, since some is sold out of state.

Generation by owner type
This breakdown is from U.S. Energy Information Administration, on a different basis than the headline figure above. Net generation from conventional hydroelectric plants in Idaho for the year, by sector (Electric utility or Independent power producer), from Form EIA-923. The two sectors sum to EIA's published Idaho hydroelectric total for the year.

| Owner type | 2025 (gwh) |
|---|---|
| Electric utility | 8,030.328 |
| Independent power producer | 820.337 |
- Form EIA-860 lists only plants of 1 megawatt of nameplate capacity or larger, so micro-hydro is absent.
- The operator named here is the Form EIA-860 respondent (the utility or company that reports the plant), not necessarily its owner; joint or non-operator ownership is not resolved here. A separate dataset on this site covers out-of-state plants an Idaho-based owner holds a share of.
- Which utility or market buys an independent power producer's output is not recorded in either form.
- A generator on standby (Form EIA-860 Status "SB") does not qualify its plant for this dataset even if Form EIA-923 later reports generation for it in the year; Little Wood Hydro Project (plant 54386, Blaine County) is the 2024 example, reporting 4,751 megawatt-hours on standby status.
- Two plants in the 2024 and 2025 lists have no matching Form EIA-923 generation row, so their net generation is left blank rather than shown as zero: El Dorado Hydro Elk Creek and Rock Creek II, both operated by Hydroland Omega LLC.
- The generation-by-owner-type figures are not a re-sum of this dataset's per-plant rows. They total every Idaho, water-fuel row in Form EIA-923, including generation Form EIA-923 attributes to plants EIA-860 does not list as operating that year and to EIA's own unattributed state-level residual, because that is what EIA's own published Idaho hydroelectric generation total (the Hydroelectric Conventional line of its net generation by state) is built from.
- A plant is in the dataset when at least one of its hydroelectric generators is marked operating (Status OP). Its nameplate capacity and first operating year then cover all of its hydroelectric generators EIA counts as operable, including units on standby or out of service at year end (Status SB, OS, OA), because Form EIA-923 credits their generation to the plant; a plant's other generators (a diesel backup unit, for example) are not counted.
- History runs 2014 to 2025; 2013 and earlier use a differently structured Form EIA-923 file this dataset does not read.

Caveats
- Generation figures are net of plant use (station power), not gross generation.
- The source publishes megawatthours; values here are divided by 1000 to store gigawatthours.
- The by-source breakdown is stored for Idaho and the US only; a source is omitted for a year EIA collected none.

- Dataset
- Hydropower share of electricity use (computed by Understand Idaho)
- Geography
- All 50 states, the District of Columbia and the nation, since the source file already covers every state. Net electricity generation by energy source is stored for Idaho and the nation only. The hydroelectric share of net generation covers every state, the District of Columbia and the nation, wherever the source reports a hydroelectric row for that place and year (49 of 52).

Caveats
- Computed by Understand Idaho from Net Generation by State (EIA-923) and Retail Sales and Price of Electricity by State (EIA-861); it is not a figure the publisher releases.
- Hydro share excludes pumped storage, which EIA reports as a separate energy source.
- The source publishes sales in megawatthours; values here are divided by 1000 to store gigawatthours.
- Total retail sales includes each geography's 'Other' sector sales (1990 to 2002); those are not broken out in the by-sector breakdown.
- Figures cover the Total Electric Industry (all provider types combined), not any single provider type.
Inputs: Net Generation by State (EIA-923) and Retail Sales and Price of Electricity by State (EIA-861).
