Daleville AreaTransmission Improvements Project

Appalachian Power representatives plan to upgrade the electric transmission grid in Botetourt County. The Daleville Area Transmission Improvements Project consists of the following:

• Upgrading approximately 17 miles* of 138-kilovolt (kV) transmission line with a larger-capacity conductor wire. The line will be rebuilt in or near the existing right-of-way.
  • *For the ~7-mile portion from Mount Union Substation – Cloverdale Substation, the transmission line will primarily be reconductored (same structures, new wire). The remaining ~10 miles of line must be rebuilt due to structure capacity.
• Upgrading Cloverdale, Trinity, Mount Union, and Botetourt substations.
• Building the proposed Windy Pass (138-kV) Substation.
• Building two approximately 1.3-mile-long 138-kV transmission lines parallel to each other.
  • *NOTE – this length is an extension of the originally announced 0.1 miles. The additional 1.2-mile extension is on customer-owned property and is the same size/shape/voltage as the rest of the project.
• Filing an application with the Virginia State Corporation Commission (SCC).

The project provides power to a new customer, supports increasing electricity demand, and enhances electric service reliability for customers.
