Midwest Transmission Project

Craig, Missouri to Maryville | Missouri to Sibley, Missouri

The Midwest Transmission Project involved the installation of a new 345kV transmission line in northeast Missouri and southeast Nebraska. The project extends approximately 180 miles from the substation located at Omaha Public Power District’s (OPPD) Nebraska City generating station to the substation located at KCP&L’s Sibley generating station. A 345kV switching station was also constructed south of Maryville, Missouri. The project was a joint venture between Transource and OPPD. Transource was responsible for construction of the Missouri portion of the project and the first two structures in Nebraska - 135 miles. OPPD was responsible for the remaining construction in Nebraska - 45 miles. Kenny Construction Company (KCC) mobilized the project in November 2014 to begin ROW clearing activities, construction specifications and RFP documents for line construction and material management. Safety orientations were provided to all employees working on the project.

The Challenge

Muddy conditions due to high rainfalls in late 2015 caused challenges for the drilling and line construction crews. This created higher risk than normal for the standard operations. Another challenge was faced when the IMPACCT deadend bodies developed cracks from implosions which KCC discovered during the QA/QC check. Crop loss and damage was another issue during the project due to the inclement weather and changes in construction plans.

The Solution

Despite the challenges faced, the substantial completion dates for the construction of both the line and switching station were met. The line was energized in December 2016.  Crop loss damage claims associated with several tracts that the line ran through were processed and repaired by KCC before the project was completed. Final reviews were also held with landowners for final signoff and closeout of the tracts.
