ITC Michigan, through its Michigan Electric Transmission Company, LLC (METC) subsidiary, is upgrading electricity transmission infrastructure in Michigan. ITC is rebuilding approximately eight miles of the Four Mile – Wealthy 138,000 volt (138 kV) transmission line, replacing the existing structures with new single-circuit monopoles designed for higher-rated conductor (wire) and optical ground wire (OPGW). OPGW combines the shielding and communication functions, and provides for improved communication speed and reliability of the line. Construction began in fall 2020 and be completed in spring 2021.
The Four Mile – Wealthy 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.
