Indiana Michigan Power representatives plan power grid upgrades to improve electric reliability for customers in Mishawaka and St. Joseph County.
The East Mishawaka Transmission Line Project involves rebuilding about 4 miles of 138-kilovolt transmission line from an existing power pole near Beech Road to Twin Branch Substation off Twin Lakes Drive.
The project strengthens the electric transmission system by replacing aging lattice towers from the 1920s with modern steel poles. The existing transmission line consists of damaged equipment and requires frequent maintenance in its current condition. Rebuilding the line with modern equipment improves the line’s operational performance, reduces the likelihood of extended power outages and enhances electric reliability for area customers.
Company officials expect construction to begin early 2024 and conclude summer 2025.
September 2023: Company officials are completing pre-constructions activities in preparation for construction start in early 2024.
The project involves installing steel poles.
Typical Pole Height: Approximately 115 feet*
Typical Right-of-Way Width: Approximately 100 feet*
*Exact structure, height and right-of-way requirements may vary.
