Idaho Power - Ranking DamsLetter to Editor from Reed Burkholder of Boise
June 2, 1999 Idaho Mountain Express
It's important to understand where each household in Idaho gets its electricity.
Let's look at the Idaho Power Company which serves about 60% of Idaho. It is supplied mainly by 20 dams and coal fired plants that it owns all or part of. In order of importance, its power plants are Jim Bridger (a Wyoming Coal Fired Plant 1/3 owned by Idaho Power), Brownlee, Hells Canyon, Oxbow, C.J. Strike, Bliss, American Falls, Lower Salmon Falls, Upper Salmon Falls, Swan Falls, Milner, Lower Malad, Boardman, Twin Falls, Shoshone Falls, Upper Malad, Thousand Springs, Cascade, Valmy, and Clear Lake.
Where are the 4 lower Snake River dams -- Lower Granite, Little Goose, Lower Monumental, and Ice Harbor -- the dams being considered for partial removal in order to aid Idaho's endangered salmon and steelhead runs?
They do not make the top 20 list. Together these federal dams supply Idaho Power with about 1/6 of one percent of its electricity.

2 Includes purchases Idaho Power makes from power plants it does not own. Two examples of these are the little hydro facility at Barber Dam on the Boise about a mile upstream from the Barber Bridge. Another is the cogeneration facility at the Evergreen lumber mill between Council and New Meadows.

4 About 1/6 of one percent of Idaho Power's supply of electricity (14,878,000 MWHs in 1995) came from the 4 lower Snake River dams.
