Project Overview

Located on private land zoned for energy development, the Goldendale Energy Storage Project is a proven, cost-effective solution for storing energy and generating power when it’s needed most. The $2 billion+ project, located about eight miles southeast of Goldendale, Washington, is a closed-loop pumped storage hydropower facility that will support more than 3,000 family-wage construction jobs and spur economic growth in a region that will need more reliable and homegrown energy supply.

The most common and widespread form of energy storage, pumped storage hydro helps safeguard our electrical grid against blackouts, extreme weather events, and other potential crises that can disrupt the economy and our way of life.

The Goldendale project will store energy for 12 hours and generate 1,200 megawatts of clean electricity—enough to power a city the size of Seattle. Built on the former Columbia Gorge Aluminum smelter site within the Tuolumne Wind Farm, it will use existing roads and transmission lines for efficient power delivery. Project owner Copenhagen Infrastructure Partners (CIP) has pledged $10 million to clean up the site before construction.

Broad Support

BROAD SUPPORT FROM THE REGION

As a result of more than two decades of work by community and private partners, Goldendale has widespread support for its potential to create thousands of jobs, generate millions in annual tax revenue, and strengthen grid resilience at a time when the region’s energy needs are growing.
