Idaho electricity generation

20,035 GWh

Net electricity generation by plants inside Idaho, 2024

+12.3% since 2023 (17,842 GWh); +8.8% since 2019 (18,408 GWh); +31.9% since 2014 (15,184 GWh)

Source: U.S. Energy Information Administration, Net Generation by State (EIA-923). Data period 2024. Published .

Total net electricity generation from all producers and all energy sources by plants inside the state, for a calendar year. Electricity imported from other states is not included; a state can use far more than it generates.

Change and comparison

From 1990 (9,691 GWh) to 2024 (20,035 GWh), the change was +106.7%.

The latest figure, 2024, is the highest in the series, which begins in 1990.

Among 50 states and the District of Columbia, Idaho ranked 43rd highest in 2024. Texas was highest at 566,503 GWh and the District of Columbia lowest at 187.195 GWh.

Idaho is lowest among its neighboring states at 20,035 GWh; Montana is next above at 26,873 GWh.

Idaho's figure is 0.5% of the national figure of 4.31 million GWh.

Share from hydro, wind, solar, geothermal and biomass

68.3% in 2024. Idaho net electricity generation from Hydroelectric Conventional, Wind, Solar Thermal and Photovoltaic, Geothermal, Wood and Wood Derived Fuels and Other Biomass, summed and divided by total net generation from all sources, times 100, for a calendar year, both from the EIA. Follows EIA's own definition of renewable: hydro, wind, solar, geothermal and biomass.

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

  • 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.

Caveats

  • Computed by Understand Idaho from Net Generation by State (EIA-923); it is not a figure the publisher releases.
  • The by-source breakdown is stored for Idaho and the US only; a source is omitted for a year EIA collected none.
