Concept Vision

This proposed run-of-river concept will generate year-round and produce up to 12 MWs of power, depending on the season and associated river flow. Electricity and optical fiber would be provided to the communities of Dillingham, Aleknagik, Koliganek, New Stuyahok, Ekwok and Levelock, also supporting the electric and communications needs of Bristol Bay’s incredible wild salmon industry in these communities. Project generation potential has been estimated using over 60 years of federally collected site-specific flow data. Based upon this analysis, the seasonal generation capacity matches, or exceeds, the demand for power in these communities. This project will replace up to 1.5 million gallons of diesel fuel annually. Hydroelectric projects in Alaska have a successful history of providing electric rate reduction, reduced dependence on fossil fuels, carbon emissions mitigation and longevity. Several hydro facilities in Alaska have been in operation for more than a century and many more are currently displaying the same type of longevity potential. We believe the combination of renewable energy and increased broadband access will provide the basis for economic and social improvement and growth in the region for generations to come.

Concept Overview

This Nuyakuk River Concept location provides many advantages for low-impact hydroelectric development. Twenty Six feet of elevation drop occurs rapidly through a series of falls in a 2500’ stretch of river. The location of these falls at an oxbow (bend) would allow for a flow diversion of only 1500’ without the need for a dam. Our intent is to meet generation goals while at the same time having minimal negative impact on the environment. Key project characteristics include:

  • Natural topographic and hydrologic features that benefit diversion and reintroduction of flow
  • Vast upstream lake system that captures 1544 square miles of watershed and acts as a natural sediment trap
  • Low visual impact site with minimal project footprint
  • No disturbance of the natural course of the river
  • Short bypass reach (portion of the river that is affected) through falls area that possesses limited to no rearing or spawning habitat
  • Potentially positive impact for upstream fish passage through the bypass reach via reduction of high water velocities that currently create intermittent velocity barriers during key migration periods

UPDATES

The Revised Study Plan (RSP) was filed with FERC on August 1, 2022. The RSP describes the full suite of studies the Cooperative plans to conduct to evaluate Project feasibility. The Cooperative would like to thank everyone who participated in the study planning process via meetings/site visits and by providing written or verbal comments on the Proposed Study Plan (PSP). The study plan development has been a collaborative effort by all involved, and the Cooperative looks forward to implementation of the study program after the issuance of a Study Plan Determination by FERC. We will continue to provide you with updates and information regarding the project studies as we go forward. Comments on the RSP are due to be filed with FERC no later than 1pm AK time on August 15, 2022.
