Steam Plant Tour

Explore this engineering landmark and remnant from the era of electrification in American cities.

Join Atlas Obscura Society Seattle for a private tour of Georgetown Steam Plant to glean insight into the history of electricity's expansion into the everyday lives of Seattleites. 

The Georgetown Steam Plant, a National Historic Landmark, stands today as a reminder of the era of electrification of America's cities and a time when industry was first attracted to Seattle by its inexpensive hydroelectric power and electric trolley car system. The plant provides a great current and historical vista and can still be seen from the core of Georgetown along 13th Avenue South. Built in 1906-1907 by the Seattle Electric Company on 18 acres of land along the Duwamish River, the plant was once at the center of the bustling residential and industrial activity in the rapidly growing Georgetown neighborhood of Seattle.

In 1912, Puget Sound Traction, Power and Light purchased the Seattle Electric Company and consolidated all of the electric companies in the Seattle area except for the municipal utility. In the process, the Georgetown Steam Plant was relegated to a minor role in the system, primarily serving as a standby, or "peaking," facility to provide a supplemental source of power only during periods of highest demand. In 1951, the City of Seattle Department of Lighting - today's Seattle City Light - purchased the plant. But with City Light's existing steam plant on Lake Union, and its major hydroelectric project on the Skagit River, the need for power from the Georgetown facility was reduced even further. Nevertheless, City Light continued to operate the plant on a very limited basis, until the 1970s. In recent years, City Light staff and volunteers have been working to restore the plant and each piece of equipment.
