  • Long-Range Transmission Plan (LRTP) – Michigan

    Long-Range Transmission Plan (LRTP) – Michigan

    As part of Tranche 1, approximately 100 new miles of 345kV electric transmission lines are to be constructed in Michigan, with an estimated investment of $850 million. These lines will run from ITC’s Nelson Rd substation (Gratiot County) to Oneida substation (Eaton County); and Duck Lake substation (new substation, potentially targeted to locate in northern…

  • Morocco Substation

    Morocco Substation

    To alleviate stress on the transmission system and provide a more stable and reliable source of energy for the area, ITC will build a new substation, named Morocco, in Deerfield Township. It will connect the existing local 138,000-volt (138 kV) system to a 345,000-volt (345 kV) line. The Morocco substation will use a transformer to…

  • Michigan Thumb Loop 345kV Transmission Line

    Michigan Thumb Loop 345kV Transmission Line

    ITC Michigan, through its ITCTransmission subsidiary, completed the Thumb Loop high-voltage transmission project in May 2015. ITC invested $510 million to build the 345,000 volt (345 kV) line, which now serves as the backbone of a system designed to meet the identified maximum wind energy potential of Michigan’s Thumb region. It also is contributing to regional…

  • Marshall-Blackstone Transmission Line Rebuild

    Marshall-Blackstone Transmission Line Rebuild

    Portions of the electric transmission grid in Michigan were built more than 50 years ago and have experienced minimal investment since that time. The Marshall-Blackstone 138,000 volt (138kV) transmission line has become increasingly unreliable and costly to maintain as growing demand for electricity and outdated infrastructure technology have taxed its service capabilities and created the…

  • Tippy-Chase Transmission Line Rebuild

    Tippy-Chase Transmission Line Rebuild

    The Tippy-Chase 138,000 volt (138 kV) line, built more than 50 years ago, became increasingly unreliable as growing demand for electricity and outdated technology taxed its service capabilities. METC recently rebuilt the line with new steel monopole structures and aluminum conductors (wires) to increase its capacity and reliability. The project was completed in the second…

  • Alcona-Twining Transmission Line Rebuild

    Alcona-Twining Transmission Line Rebuild

    Portions of the electric transmission grid in northeastern Michigan date back to the 1950s and have experienced minimal investment since that time. The Au Sable circuit, a 110-mile, 138,000 volt (138 kV) line which runs from Zilwaukee to Mio, became increasingly unreliable as growing demand and outdated infrastructure taxed its service capabilities, especially during peak-demand…

  • Apex-Phoenix Transmission Line Project

    Apex-Phoenix Transmission Line Project

    A growing technology sector, excellent schools, and rich cultural and recreational opportunities make Ann Arbor a desirable place to live and work. This makes high-quality, reliable power increasingly important as homes and businesses are filled with sensitive electronics that can be affected by costly and inconvenient power outages. To support electric reliability and increase capacity…

  • Keystone-Hodenpyl Transmission Line Rebuild

    Keystone-Hodenpyl Transmission Line Rebuild

    Portions of the electric transmission grid in northwestern Michigan were built in the 1950’s and 60’s and have experienced minimal investment since that time. The lines and structures on the Keystone-Hodenpyl 138,000 volt (138 kV) line reached their design capacity limits and became difficult to maintain. METC  upgraded this 26-mile line in order to improve…

  • Cottage Grove-East Tawas Transmission Line Rebuild

    Cottage Grove-East Tawas Transmission Line Rebuild

    METC recently upgraded the Cottage Grove-East Tawas section of the Iosco-Karn 138,000 volt (138 kV) line in northeastern Michigan, bringing the line there up to design and construction codes. This upgrade utilizes engineered steel monopoles and aluminum conductors to increase the line’s capacity and reliability and to improve lightning protection. Work began in the first…
