Snoqualmie Falls Hydroelectric Museum
Puget Sound Energy’s Snoqualmie Falls Hydroelectric Project, built in the late 1890s about 30 miles east of Seattle, is one of the Pacific Northwest’s oldest hydropower facilities and home to the world’s first hydroelectric plant built completely underground. The Hydroelectric Museum’s exhibits are housed in Puget Sound Energy’s historic Carpenter Shop and Train Depot, which chronicle Charles H. Baker’s 1898-1899 development of the worlds first underground power station.
Snoqualmie Falls Hydroelectric Museum is open to the public Memorial Day through Labor Day 2023, Wednesday – Sunday 10:00 am – 5:00 pm. All museum activities are free of charge.
