Indiana Michigan Power (I&M) is enhancing the power grid in northern Indiana. Gravel Pit Substation and Transmission Line Upgrades is essential to improve reliability for the region.
The improvements include upgrading the Gravel Pit Substation from 34.5 kilovolts (kV) to 138 kV. In addition to the substation work, approximately 6 miles of two new 138-kV transmission lines are being constructed to reconfigure how the substation is tied into the electric grid.
The approximately $20 million investment is essential to reduce power outages in the region and speed recovery of service when outages occur. Constructing two new lines and converting to a looped service improves reliability by ensuring if an outage occurs on one line, the other line can still provide power to the substation.
