American Transmission Systems Upgrading 138 kV Substation in Northwest Ohio
American Transmission Systems (ATSI), a subsidiary of FirstEnergy, has started upgrading a 138 kV substation in Lucas County's Springfield Township, Ohio and rearranging connecting high-voltage power lines to enhance reliability for nearly 23,000 customers of Toledo Edison in the area.
ATSI has invested $24 million to expand the substation on company-owned property by 17,870 square feet, a 58% increase in the size of its footprint, to install new automated devices and allow the company to enhance and reorganize the existing transmission lines.
The process will help reduce the number of power outages experienced by customers and make it easier for the station to be maintained without power interruptions.
ATSI will also upgrade more than 10 miles of existing transmission lines connecting to the substation and construct a one-mile section of new line. The project is expected to be completed in mid-2025.
