Green Power - Nature’s Energy

Energy generated by water is clean and reliable.

Two of the Cooperative’s hydroelectric facilities were the first certified low-impact hydropower projects in Idaho. We know fishing on our area’s rivers and stream is important to our members and our economy. That is why Fall River invested in projects at our hydroelectric facilities to enhance our fisheries, while making the clean power you rely on.

Your Cooperative also co-owns the Coffin Butte Resource Project in central Oregon. Coffin Butte uses methane gas, discharged by a landfill, to produce renewable energy. Methane gas is naturally released during decomposition and it is 21 times worse than carbon dioxide in terms of preventing heat loss from the atmosphere. Your Cooperative receives renewable energy credits for 3 percent of the total power produced at Coffin Butte, roughly 1.2 megawatts annually.

Island Park Hydropower Project

In 2001, the Island Park Hydropower Project became the first project in Idaho certified low-impact by the Low-Impact Hydropower Institute (LIHI). LIHI renewed its certification in 2006. The Island Park Hydropower plant is on a dam constructed in 1939 for irrigation. The hydropower facility does not effect dam operations or flows released from Island Park Reservoir.

The Cooperative installed an aeration basin below the dam to oxygenate water as it comes over the dam’s large drop. The aeration basin promotes fish survival below the dam and a fish screen on the turbine intake keeps fish from becoming entrained in the hydropower facility. Island Park Hydro produces roughly 20,000 megawatts of clean power each year, 86 percent of the power available through the Green Power Program.

Buffalo River Hydropower Project

In 2006, the Buffalo River Hydropower Project became the second project certified in Idaho by the Low-Impact Hydropower Institute. The Cooperative installed a 270 foot-long fish ladder to allow fish to move upstream over the 12 foot-high dam and into the Buffalo River’s habitat. Fish screens on the turbine intake promote survival of fish passing downstream.

The Henry’s Fork Foundation, a private non-profit organization, monitors fish moving upstream and downstream through the facility. Monitoring data shows the fish passage infrastructure installed by the Cooperative is successful. You can find out more about long-term monitoring of the project at

The Buffalo River Hydro produces roughly 2,000 megawatts of clean power each year, roughly 9 percent of the power offered through the Green Power Program.
