Duke Energy Downtown Electrical Substation

The City of Asheville is committed to a collaborative and well-reasoned approach to identifying a suitable site for Duke Energy’s rebuild of the downtown electrical substation, currently located on Duke Energy property behind the Harrah’s Cherokee Center in downtown Asheville. The rebuild of the substation is critical to the area’s power reliability. The City of Asheville worked with Duke Energy during a temporary pause to identify a suitable location for the Rankin Avenue substation.

The following project guiding principles informed the process:

Provide reliable electricity by rebuilding the aging substation.
Maintain the option to maintain and/or renovate the Thomas Wolfe Auditorium.
Design the site so that there is minimal tree impact.
Develop design elements that are in keeping with the surrounding area.
Ensure that if the site design requires a temporary substation, it is portable with no foundations.

For more information about Duke Energy’s project, please see their project website.

Next Steps

Duke Energy is working through the City’s approval process. Pending approval, Duke Energy will begin the construction phases of the project. As part of the construction process for the Rankin Avenue substation, Duke Energy will place a mobile substation on its Patton Avenue site.

Once construction is complete for the Rankin Avenue substation, Duke Energy will remove the mobile substation and a new GIS substation will be located at the Patton Avenue site.

Duke Energy’s plans for the Patton Avenue location include a GIS (gas-insulated, high-voltage switchgear) substation, which the City Council approved in 2019.

Background

Duke Energy’s current downtown substation is over 50 years old. It must be replaced to accommodate the increasing utility needs of our downtown businesses and residents and continue providing reliable electricity.

In August 2022, the City of Asheville and Duke Energy temporarily paused the project to allow further consideration of options and community input. Utilizing the input received to date, the City of Asheville and Duke Energy staff reviewed possible options for Duke’s rebuild of the current substation.
