Youngs Creek Hydro Project

In 2008, the PUD purchased the partially constructed Youngs Creek Hydroelectric Project. Construction of this project began in the mid-1990s but was never completed. It is located just south of the city of Sultan, Washington. The powerhouse is located above a natural impassible barrier to fish on Youngs Creek, which is a tributary of Elwell Creek.

The project went online in October 2011 with an estimated capacity of 7.5 megawatts with an annual production of 18,000 MWh — enough to power about 1,500 homes. It is the first new hydro project in Washington state in nearly 20 years.

The project received Renewable Energy World magazine’s 2012 Hydro Project of the Year award and the 2012 American Society of Civil Engineers’ Outstanding Achievement Award.
