Desert Power & Water Co. Electric Power Plant is located at 120 Andy Devine Avenue in Kingman, Arizona. The building was built in 1907–08 with additions in the following years 1909 through 1911. Tracy Engineering Company was the architect and McCafe Contracting Company of Los Angeles was the contractor. The oil-fired plant was considered one of the largest steam electric power plants in the Western United States. It had a powerhouse, transformer house and office for Desert Power and Water. It operated until 1938; Hoover Dam took over the power supply. The building was vacant for some time, then used as a salvage yard.
