Cushman Substation

UPDATE: July 19, 2019 

Crews from Tacoma Power will complete minor rehabilitation work on the Cushman Substation beginning the week of July 22. The rehabilitation work includes painting and replacing lamp posts and the door to the substation. Work is expected to be complete by Dec. 1, 2019.


The Cushman and Adams substations were built in the mid-1920s to bring electricity from the Cushman Dam to Tacoma. For many years, the substations served as active parts of the electrical system.

How is Cushman Substation currently used?

As of Aug. 27 2018, the substation no longer energized and is not a functioning part of the utility’s power system. The building is used for heavy equipment repair and storage of materials.

What does the future hold for Cushman Substation?

Both Cushman and Adams substations are on the Tacoma Register of Historic Places. In June 2017, the Tacoma City Council determined that these portions of the property be added to the register:

  • The exteriors of both substation buildings
  • The sites surrounding both buildings (not including the non-historic electrical switchyard equipment)

Cushman Substation Building To Be Placed On Tacoma Register of Historic Places

The Council also determined that the City of Tacoma and Tacoma Power will establish a process to encourage timely redevelopment of the two properties.

During the next few years, we will continue work to identify alternatives for the equipment repair and storage currently taking place at Cushman Substation. We have also begun to identify environmental clean-up needs.
