Post Street Substation

Tour the interior of Spokane’s iconic Post Street Electric Substation, the masterpiece designed by Kirkland Cutter, and built by The Washington Water Power Company (Avista) in 1910. The building housed the transformers and switches that served the city’s streetlight system, provided power to the streetcar and interurban rail lines, and distributed electricity throughout the city, and to the region’s emerging electric grid. It remains an operating substation today.
