The Georgetown Steam Plant, located near Boeing Field in Seattle's Georgetown neighborhood, was originally constructed in 1906 for the Seattle Electric Company. The plant's overall contributions to electricity production were minor but the innovative methods and materials used to build it, the intact early-twentieth-century steam-generating equipment it houses, and the involvement of pioneering efficiency expert Frank Bunker Gilbreth, Sr. (1868-1924), in its design and construction give the Georgetown Steam Plant significant historical importance. The plant, now the Georgetown PowerPlant Museum, has been designated a National Historical Mechanical Engineering Landmark and a National Historic Landmark.
