Following more than 25 years of efforts to develop the project on a nearly 100-year-old dam, power has begun flowing from the Arrowrock Hydroelectric Project located on the Boise River in Idaho.

Clatskanie People’s Utility District (PUD), along with five Boise area irrigation districts including Boise-Kuna, Nampa and Meridian, New York, Wilder of Idaho and Big Bend of Oregon developed the 18-megawatt project, with Clatskanie obtaining the 91,000-MWh of electricity expected to be produced in an average year, satisfying approximately eight percent of Clatskanie’s current energy needs, roughly equal to the electrical consumption of 7,500 typical households.

Construction of this project took less than 18 months and was done within the budget.

"It can be touted as perhaps the most modern and green hydroelectric project in the world,” says Greg Booth, PUD general manager. "We chose to invest in this wonderful hydro opportunity, which on a capacity basis is comparable in cost to wind projects but we’ll receive twice as much energy.”

The addition of Arrowrock to Clatskanie’s power portfolio will help meet Oregon Renewable Energy mandates, which requires mid-size utilities to get 10 percent of their power from qualifying renewable energy resources by 2025. It will also help to maintain Clatskanie’s ability to provide among the lowest electrical rates in the nation.
