Prestonsburg - ThelmaTransmission Line Rebuild Project

Kentucky Power officials plan to upgrade the electric transmission grid in Floyd and Johnson counties.

The project involves:

• Rebuilding approximately 14 miles of transmission line to 69-kV standards between Prestonsburg and Thelma substations
• Retiring approximately 2 miles of 46-kV transmission line between Kenwood Substation and Van Lear Switch Station
• Retiring Jenny Wiley Switch Station
• Retiring Van Lear Switch Station

The existing transmission line has experienced multiple power outages in recent years due to lightning and other causes. Currently, the customers served from the Kenwood Substation may experience longer restoration time when the transmission line experiences an outage.

AEP and PJM, the regional transmission organization that monitors the electric transmission grid in our region, have identified additional needs for the upgrades. The proposed upgrades will mitigate identified reliability criteria violations and strengthens the transmission system to increase electric reliability for the area customers.

The proposed upgrades:

• Allow crews to rebuild the line in a more suitable location. The existing line
has no road access and is in mountainous terrain. Walking is the only way to access many of the structures
• Allow crews to replace aging wooden structures with modern steel
structures
• Allow crews to add modern equipment that protects the line from lightning strikes

May 2023: The project team has determined a proposed power line route after reviewing input that landowners and community members provided during an open house in December 2022. Company representatives plan to submit an application to the Kentucky Public Service Commission (PSC) in early 2024. If the PSC accepts Kentucky Power’s application, property owners along the proposed route can expect to receive another mailing explaining how to participate in the project approval process.

December 2022: Kentucky Power representatives hosted an in-person open house on December 5, 2022 to provide an opportunity for residents to meet and talk with project representatives.
