Current TVA Transmission System Projects

Alabama

Mulberry, Alabama (Cullman County)

Update – November 2023

TVA has identified the preferred location for transmission improvements that would provide power for growing load and increase power reliability in the Colony, Arkadelphia, and Mulberry River areas near Hanceville, Alabama, in Cullman County.

TVA evaluated each route using social, engineering, and environmental factors.  Information sources included available data, aerial photography, limited onsite reviews, public review and comment, and property owner input.  Based on public input and evaluation, the preferred route is expected to have the least overall project impacts of the alternatives.

TVA’s proposed 5.7-mile line would begin at TVA’s existing Hanceville-Bremen 161-kilovolt Transmission line, north of the intersection of County Roads 588 and 522 in Hanceville, and end at Cullman Electric’s Mulberry Substation to be located on the north side of Alabama Highway 91 between County Roads 503 and 504.

The route selected is Route No. 6 which consists of preferred Tap 2 and Segment Nos. 2, 4, 6, 9, 13, 17, and 18 as presented at the open house in Hanceville June 29, 2023, and online at the virtual open house from June 29 through July 31, 2023. 

The new line will be built using both single- and double-pole (H-frame), steel structures centered on new 100-foot-wide right of way.

Surveys of the right of way are scheduled to begin in spring 2024.

Easement purchases are scheduled to begin in fall 2025.

Construction is scheduled to begin in summer 2026.

The line is scheduled to be in service in winter 2026-2027.

The National Environmental Policy Act review is pending. 

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Colony, Arkadelphia, and Mulberry River areas near Hanceville, Alabama, in Cullman County.

Cullman Electric operates a 46-kilovolt sub-transmission system which was built mostly in the 1960s and has reached capacity across many sections.  Cullman Electric’s Hanceville Industrial Park 46-kilovolt Substation and the 46-kilovolt line that serves it have aged and are due for substantial maintenance, rebuild, or replacement.  The Hanceville Industrial Park 46-kilovolt Substation serves the southeastern portion of Cullman Electric’s territory and provides 13-kilovolt distribution to the area.  Cullman Electric experiences up to a 7 percent voltage drop on the line serving the Hanceville Industrial Park Substation.  Due to the age and condition of these facilities, Cullman Electric has determined to retire the 46-kilovolt line and substation and build the Mulberry 161-kilovolt Substation.  This project would increase power reliability and flexibility and provide capacity for future load growth in the Colony, Arkadelphia, and Mulberry River areas near Hanceville, Alabama.

Cullman Electric will build the Mulberry 161-kilovolt Substation on the north side of Alabama Highway 91 between County Roads 503 and 504.

TVA proposes to build from about 5 to 7 miles of 161-kilovolt, single-circuit power line to serve the new station.

The proposed power line would begin at TVA’s Hanceville-Bremen 161-kilovolt Transmission Line and extend south to the new Mulberry Substation.

There are 3 possible tap point locations, 18 alternative line segments, and 14 route options under consideration.

The line would be built using both single- and double-pole (H-frame), steel structures centered on new 100-foot-wide right of way.  The scheduled completion date for this project is early winter 2026-2027.

TVA will hold an open house on Thursday, June 29, 2023, to provide information, answer questions and receive comments about the proposed transmission project.  For those unable to attend the open house June 29, 2023, TVA is providing a virtual open house from June 29 through July 31, 2023, online at tvavirtual.com/mulberry.

The project is expected to be in service in early winter 2026-2027.  Construction is scheduled to begin in summer 2026.  (Dates are subject to change. Unexpected issues may arise, resulting in the need to adjust the schedule.)

Environmental Reviews

The appropriate National Environmental Policy Act review will be conducted to ensure that the environmental impacts are minimized. TVA attempts to minimize any land requirements, private property impacts, and environmental impacts associated with this project.

Efforts are made during the siting process to avoid or minimize impacts to floodplains and wetlands in accordance with Executive Orders 11988 and 11990. Floodplains and wetlands are shown on the referenced map. The map illustrates how the route avoids or impacts floodplains and wetlands. Because of project and topographic constraints and because of minimizing impacts to other social, environmental, and engineering resources, no practicable alternative may be available that would allow complete avoidance of impacts to floodplains and wetlands which may require mitigation for minimizing impacts. Also, best management practices would be utilized throughout the project to minimize adverse floodplain and wetland impacts. In compliance with Section 404 of the Clean Water Act, TVA will be coordinating wetland findings with U.S. Army Corps of Engineers.

Also, best management practices would be utilized throughout the project to minimize adverse floodplain and wetland impacts. In compliance with Section 404 of the Clean Water Act, TVA will be coordinating wetland findings with U.S. Army Corps of Engineers.

Mulberry, Alabama (Cullman County)

Update – November 2023

TVA has identified the preferred location for transmission improvements that would provide power for growing load and increase power reliability in the Colony, Arkadelphia, and Mulberry River areas near Hanceville, Alabama, in Cullman County.

TVA evaluated each route using social, engineering, and environmental factors.  Information sources included available data, aerial photography, limited onsite reviews, public review and comment, and property owner input.  Based on public input and evaluation, the preferred route is expected to have the least overall project impacts of the alternatives.

TVA’s proposed 5.7-mile line would begin at TVA’s existing Hanceville-Bremen 161-kilovolt Transmission line, north of the intersection of County Roads 588 and 522 in Hanceville, and end at Cullman Electric’s Mulberry Substation to be located on the north side of Alabama Highway 91 between County Roads 503 and 504.

The route selected is Route No. 6 which consists of preferred Tap 2 and Segment Nos. 2, 4, 6, 9, 13, 17, and 18 as presented at the open house in Hanceville June 29, 2023, and online at the virtual open house from June 29 through July 31, 2023. 

The new line will be built using both single- and double-pole (H-frame), steel structures centered on new 100-foot-wide right of way.

Surveys of the right of way are scheduled to begin in spring 2024.

Easement purchases are scheduled to begin in fall 2025.

Construction is scheduled to begin in summer 2026.

The line is scheduled to be in service in winter 2026-2027.

The National Environmental Policy Act review is pending. 

Background

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Colony, Arkadelphia, and Mulberry River areas near Hanceville, Alabama, in Cullman County.

Cullman Electric operates a 46-kilovolt sub-transmission system which was built mostly in the 1960s and has reached capacity across many sections.  Cullman Electric’s Hanceville Industrial Park 46-kilovolt Substation and the 46-kilovolt line that serves it have aged and are due for substantial maintenance, rebuild, or replacement.  The Hanceville Industrial Park 46-kilovolt Substation serves the southeastern portion of Cullman Electric’s territory and provides 13-kilovolt distribution to the area.  Cullman Electric experiences up to a 7 percent voltage drop on the line serving the Hanceville Industrial Park Substation.  Due to the age and condition of these facilities, Cullman Electric has determined to retire the 46-kilovolt line and substation and build the Mulberry 161-kilovolt Substation.  This project would increase power reliability and flexibility and provide capacity for future load growth in the Colony, Arkadelphia, and Mulberry River areas near Hanceville, Alabama.

Cullman Electric will build the Mulberry 161-kilovolt Substation on the north side of Alabama Highway 91 between County Roads 503 and 504.

TVA proposes to build from about 5 to 7 miles of 161-kilovolt, single-circuit power line to serve the new station.

The proposed power line would begin at TVA’s Hanceville-Bremen 161-kilovolt Transmission Line and extend south to the new Mulberry Substation.

There are 3 possible tap point locations, 18 alternative line segments, and 14 route options under consideration.

The line would be built using both single- and double-pole (H-frame), steel structures centered on new 100-foot-wide right of way.  The scheduled completion date for this project is early winter 2026-2027.

TVA will hold an open house on Thursday, June 29, 2023, to provide information, answer questions and receive comments about the proposed transmission project.  For those unable to attend the open house June 29, 2023, TVA is providing a virtual open house from June 29 through July 31, 2023, online at tvavirtual.com/mulberry.

The project is expected to be in service in early winter 2026-2027.  Construction is scheduled to begin in summer 2026.  (Dates are subject to change. Unexpected issues may arise, resulting in the need to adjust the schedule.)

Environmental Reviews

The appropriate National Environmental Policy Act review will be conducted to ensure that the environmental impacts are minimized. TVA attempts to minimize any land requirements, private property impacts, and environmental impacts associated with this project.

Efforts are made during the siting process to avoid or minimize impacts to floodplains and wetlands in accordance with Executive Orders 11988 and 11990. Floodplains and wetlands are shown on the referenced map. The map illustrates how the route avoids or impacts floodplains and wetlands. Because of project and topographic constraints and because of minimizing impacts to other social, environmental, and engineering resources, no practicable alternative may be available that would allow complete avoidance of impacts to floodplains and wetlands which may require mitigation for minimizing impacts.
