To improve reliability and meet the region’s growing energy demands, ITC Michigan, through its ITC Transmission subsidiary, is constructing a new substation and transmission line in the City of Dearborn.
The project consists of a new 120,000 volt (120 kV) substation, named Mercury, that will connect to ITC’s existing 120 kV Crestwood – Arctic transmission line via a new half-mile underground transmission line. Additionally, ITC will be installing approximately 400 feet of underground line along Greenfield Rd. near the Crestwood Substation, and six miles of optical ground wire (OPGW) on its nearby Crestwood –Mercury, Ranger –Arctic and Arctic –Mercury lines, which will improve the grounding and communication functions. Construction began in July 2017 and was completed in Q1 2018.
