The Post Street Electric Substation (also called the Washington Water Power Building, The Washington Water Power Substation) is an electric substation on the Spokane River in the city of Spokane, Washington. Built in 1910, the Post Street substation served the needs of the city’s growing electric grid as well as the surrounding area.[1] The substation consolidates and delivers power generated by the Upper Falls and the Monroe Street hydroelectric plants.[2][3] The building is one of many contributions to Spokane’s downtown area by renowned Pacific Northwest architect Kirtland K. Cutter.[4] In May 2014 the Huntington Park and City Plaza was opened below the substation as part of an effort to revitalize the area.[5]

History edit

The Post Street Electric Substation was designed by Kirtland K. Cutter for the Washington Water Power Company[4] and constructed in 1910 to serve as a low-tension distributing and converting station and as Washington Water Power’s primary substation in Spokane.[3] The first transformer on the site was placed in 1909, with six being in place by 1911. The building was designed to have ample interior space in which to expand its capacity.[3] The substation initially delivered power to Spokane’s street light and streetcar system.[2] The substation continued to power Spokane’s streetcar network, which was largely owned by Washington Water Power, until the city abandoned electric streetcars in 1936.[6] When Washington Water Power Corporation rebranded itself as Avista in 1999, the large sign atop the Post Street substation reading Washington Water Power remained unchanged.[7]  

Design edit

The Post Street Electric Substation is of brick construction and a concrete base[3] with a foundation on the stony south bank of the Spokane River. The exterior of the building is a façade built to compliment the surrounding downtown area as well as to protect the internal electrical equipment, with the interior being mostly empty and containing the transformers and switches necessary for the building’s primary function as an electrical substation.[1] The sides of the building have tall rectangular glass windows curved off at the top. On top of the eastward and westward facing sides there are large signs which read “Washington Water Power” in all capitalized, green letters, one of the largest such Washington Water Power signs in Washington State[7] and the only remaining publicly-displayed sign bearing the company’s former name.[6] Local Spokane columnist Shawn Vestal praised this sign in a 2019 editorial piece, calling it “one hell of a vestige” of the building’s past as a fixture of the Spokane landscape.[8]

Public Opinion edit

The Post Street substation today is generally regarded positively as a longstanding Spokane landmark and a cornerstone of Spokane’s architectural identity.[4][8]
