ITC Michigan, through its ITCTransmission subsidiary, is upgrading electricity transmission infrastructure in Michigan. ITC will rebuild 1.3 miles of wood pole structures from Enrico Fermi to the Toll Road substation, and 3.7 miles of wood pole structures along the Toll Road – Shoal 120,000 volt (120 kV) transmission line. The wood poles will be replaced with 120 kV single-circuit steel monopoles and higher rated conductor (wires) and optical ground wire (OPGW). OPGW combines the shielding and communication functions, and provides for improved communication speed and reliability of the line. Construction is expected to begin in fall 2020 and be completed in spring 2021.
The Fermi – Shoal Rebuild Project is an example of ITC’s ongoing commitment to the operational efficiency and reliability of Michigan’s high-voltage transmission grid. The company has invested more than $4.7 billion in capital project maintenance and transmission infrastructure improvements in Michigan since 2003. These investments are improving the reliability and safety of the transmission infrastructure while ensuring its ability to meet new energy demands.
