We are always working to provide reliable service to Ohioans. A major part of providing that reliable service is modernizing AEP’s transmission system, which includes 40,000 miles of high-voltage power lines across 10 states.

What is the Transmission System?

Before AEP Ohio can safely deliver power to your home, it must route through the transmission system. Think about when you travel long distances—you likely use freeways and highways. Similarly, our transmission system carries high-voltage power over long distances before it reaches distribution equipment. Stronger, larger steel transmission poles can better withstand extreme weather events. Also, modernized equipment helps us identify and respond to problems quickly while providing greater protection from cyber and physical threats.

Our team is constantly evaluating the transmission system and making proactive improvements to ensure you have the power you need. Unfortunately, almost 11,000 miles of transmission lines will be more than 70 years old within the next decade. By the time a line is 75 years old, the risk of it failing and causing an outage is around eight times greater than when it was 40 years old. That’s why we’re investing today. Time is of the essence because it can sometimes take five years or more to design and build a transmission line.

What are We Doing in Your Area?

  • Wheelersburg: We’re building about five miles of 138-kiloVolt (kV) power line and rebuilding two miles of power line. The project will provide an additional power source to the area and enhance service reliability for customers.
  • Millbrook Park-South Point: We’re rebuilding about 35 miles of power line. Replacing existing 90-year-old lattice towers with modern steel poles reduces the need for ongoing maintenance and improves service reliability.
  • Hillsboro-Millbrook Park: We’re rebuilding about 50 miles of 138-kV transmission line in the existing right of way. Improvements reduce the likelihood of outages in the area and speed restoration when outages occur.
