Horseshoe Bend
Technical data
The Horseshoe Bend Facility uses the motive force of the water from the
Payette
River
which hydrographic basin stretches some 5,776 square-kilometres upstream. Three rivers, the North Folk, Middle Fork and South Fork, as well as two reservoirs feed the
Payette
River
.
The source of the water in these rivers comes from the high peaks at the North of Idaho.
Two Kaplan turbines give the Horseshoe Bend Facility an installed capacity of 9.5 MW. The expected annual production of electricity is 46,800 MWh, or the equivalent to fill the needs in electricity of more than 2850 households in
Idaho
.

From an environmental standpoint, the site of the project includes a by-pass canal for kayakers and fishes as well as other aquatic species in order to maintain the navigation on the river and preserve the ecosystem.
In addition, efforts were deployed to recreate wetlands that were partly dried at the time of construction of the facility in the 90’s. In order to be compliant with the Wetlands Protection Program of the US Army – Corps of Engineers, almost 67 acres (27 hectares) will be covered by cottonwood.
