b'SYSTEMS INTEGRATION 230KV TRANSMISSSION LINE STORM DAMAGE SUPPORT Lifeline Sector: Power | Location: Fossum, MN In 2018, a severe weather event took 70 transmission structures down and placed 12.5 miles of 230kV transmission line out of service. When the firm that had been doing the prior design work was not able to meet the requested timeline for the rebuild, Minnkota Power Cooperative, the electrical generation and transmission cooperative who ownedtransmissionthese assets, reached out to Ulteig instead.Ulteig worked quickly to assemble a team, and in five weeks, completely re-designed the line while the existing conductor and structures were being demolished. The new design consisted of wood pole H-frame tangents, guyed wood three pole deadends and an increased number of terminal dead end structures to minimize service loss from future tornado and severe straight-line wind gusts.TRANSMISSIONIn addition to design, Ulteig also took theUlteig has a long history of surveying andExpertise Lattice tower analysislead on construction staking and generatedengineering AC and DC transmission linesPermitting assistance,Foundation designthe specifications and bid documents for thefor public and private clients.
