Black Hawk - Hazleton 345 kV Line Build

ITC Midwest built the Black Hawk-Hazleton 345 kV line from ITC’s Hazleton substation in Buchanan County, Iowa, to an interconnection with a MidAmerican Energy line in Black Hawk County. The line is co-located on structures along the same route with an existing 161 kV line already in place.

Multiple Benefits
The Black Hawk–Hazleton line is a portion of one of 17 transmission projects that MISO, the independent transmission organization for the 11-state region that includes Iowa, studied and designated as a “Multi-Value Project” (MVP). The Black Hawk– Hazleton line will bring four major types of benefits to northern Iowa and the rest of the MISO region: improved reliability, expanded access to generation sources, increased system efficiency, and economic investment.

PROJECT PROFILE
 

  • How big will this line be?
    Depending on the terrain along the line route, the new tubular steel poles are between 120 to 170 feet tall and are spaced approximately 500 to 1,000 feet part, varying with terrain and local conditions. The structures are installed on concrete foundations that are between eight and 12 feet in diameter
  • How was this route chosen?
    The primary factor in the line route is the location of the Hazleton substation and the connection point to the MidAmerican Energy line in Black Hawk County. To minimize impact on landowners, ITC is locating the new line on the same route as an existing 161 kV line, placing both lines on opposite sides of new structures. To determine an appropriate route to connect the two substations, ITC Midwest carefully considered all of the factors mandated by Iowa Code §478.18(2) and Section 11.1(7) of the Iowa Administrative Code.
  • What is the timing for construction?
    ITC began construction in 2015 with projected completion and clean up by the end of 2015.
