Portions of the electric transmission grid in western Michigan were built more than 50 years ago and have received limited investment since that time. ITC Michigan, through its Michigan Electric Transmission Company (METC) subsidiary, has upgraded the southern segment of the Croton-Mecosta 138,000 volt (138 kV) line with new steel monopole structures and aluminum conductors to increase its capacity and reliability and also allow for future expansion. The project began in the first quarter of 2014 and was completed in November 2014.
The Croton-Mecosta line rebuild 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 $2.7 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.
