As a provider of an essential service, we are working to ensure we are here for our customers, our community and our employees as coronavirus impacts the region.

With Governor Inslee’s phased reopening of select aspects of our community and economy, such as the construction sector, PSE is gradually returning maintenance and construction crews back into the field. PSE’s highest priority is the health and safety of our employees and communities. As such, we continue to adhere to current CDC guidance regarding COVID-19 while working in our community.

We are requiring our employees to maintain social distancing while working in the field. We encourage our customers to do the same when engaging with our employees.

Snoqualmie Falls Hydroelectric Project

Puget Sound Energy's Snoqualmie Falls Hydroelectric Project, located about 30 miles east of Seattle on the western slopes of the Cascade Mountains, is one of the oldest hydropower plants in the United States.

The Snoqualmie Falls Hydroelectric Project is located on the Snoqualmie River in Snoqualmie, Washington. The Project consists of a low diversion dam located 150 feet upstream from Snoqualmie Falls and two powerhouses (Plants 1 and 2) with a total generating capacity of 54 megawatts. Snoqualmie Falls Plant 1, located in a cavern 270 feet below Snoqualmie Falls, was originally built in 1898 as the world's first completely underground powerhouse. Snoqualmie Falls Plant 2, about a quarter-mile downstream from Plant 1, was built in 1910 and expanded in 1957.

After operating for more than a century, the facility still produces clean, renewable electricity for PSE customers. The project contains a small diversion structure just upstream from Snoqualmie Falls, and two powerhouses. The first powerhouse is encased in bedrock 260 feet beneath the surface and was the world's first completely underground power plant. Together, the two power plants currently have 53 megawatts of generating capacity.

Puget Sound Energy redeveloped the Snoqualmie Falls Project between 2010 and 2015, making extensive improvements to Plants 1 and Plant 2 as well as Snoqualmie Falls Park and historic buildings near the falls.

The project received a new, 40-year federal operating license in 2004. The facility recently underwent a four-year redevelopment project, which included substantial upgrades and enhancements to the power-generating infrastructure and public recreational facilities. Check out the recreational opportunities we offer at the facility.
