Bonneville Power Administration Burley Substation, 1221 Albion Avenue, Burley, Cassia County, ID

Significance: The Burley Substation is significant as a distribution component of the United States Reclamation Service's Minidoka Project, which pioneered agricultural development and the market for commercial power in the Burley vicinity of southern Idaho during the early twentieth century. Its construction accelerated urban growth in Burley and electrical power transmitted through this station began to dominate the region's residential and commercial heating and power needs. Architecturally, the station is unique as the only brick substation in the Minidoka system and is representative of the changing nature of electrical power demand. The original 1913-constructed structure increased in size with a 1921 addition; however, materials, construction style, and continuity of design remained consistent between the two construction phases. Resident interior electrical components of the station evolved technologically during the station's operation, but at present all electrical transmission-related gear has been removed from the structure. Minidoka Dam, which generated the hydroelectric power distributed through the Burley Substation, has previously been included in the National Register of Historic Places.
