Georgetown Steam Plant

The Georgetown Steam Plant is a National Historic Landmark - a reminder of the era of electrification when industry was first attracted to Seattle by its inexpensive hydroelectric power and electric trolley car system. It is also a Historic Mechanical Engineering Landmark, a Seattle Landmark, and is listed on the National Register of Historic Places.

Built in 1906-1907 by the Seattle Electric Company on 18 acres of land along the Duwamish River, it was once at the center of the rapidly growing Georgetown neighborhood.

The plant's two vertical Curtis Turbines helped establish the steam turbine as capable of producing large amounts of power, more cheaply and efficiently than other generators at the time.

Today, tours and open houses are available at no charge for anyone wanting to learn more about Seattle's energy history.
