Northridge Substation

Project Summary

ITC Holdings Corp., through its Michigan Electric Transmission Company, LLC (METC) subsidiary, is upgrading electricity transmission infrastructure in west Michigan. The existing high voltage electrical equipment in the outdated Four Mile 138kV station has been in-service for decades with aging equipment and limited reliability.

The new 138kV Northridge substation will be built approximately 2.5 miles to the west of the existing station with modernized equipment.  This modernized station will secure electric reliability to the region, allow for future load growth, provide operational flexibility and allow needed maintenance to be performed efficiently and safely.  Included in this project are upgrades to several existing transmission lines which will feed into the new station.

Construction began in Q3 2023 and was completed in 2024.
