Mills Gap Reliability and Line Relocation Project

Mills Gap Reliability and Line Relocation Project

Project Overview

To accommodate N.C. Department of Transportation's (NCDOT) widening project for Mills Gap Road in south Asheville, existing Duke Energy distribution line infrastructure will need to be relocated.

Separately, Duke Energy will be constructing a new electrical substation at the corner of Mills Gap Road and Sweeten Creek Road. To connect this substation to the grid, a new transmission tap line will be built that will run 1.5 miles southeast along Mills Gap Road to the existing transmission corridor located near Paul Williams Lane.

This part of the project won't begin until after NCDOT has widened Mills Gap Road. For further details on the project schedule, please see the timeline below.

These projects are a result of Buncombe County and south Asheville experiencing steady growth and an increased demand for electricity over the past several years. To help meet the community’s growing energy needs and provide the reliable, affordable and increasingly clean energy our customers deserve, these upgrades are essential.
