Ider, Alabama

Power Supply Upgrade

Update—January 2016

TVA has identified the preferred route for a transmission line that would improve power reliability and reduce the significant amount of power interruptions in the Ider area. 

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.

Sand Mountain EC plans to build a substation in Ider, Alabama. TVA’s new line would tie into the Widows Creek Fossil Plant-Henagar 161-kV Transmission Line and proceed east to the new substation. The preferred route is a combination of tap alternative No. 3 and alternative route No. 3 made up of segment Nos. 1, 3, 5, and 6 proposed at the open house held in August 2015. 

The line would consist of steel pole structures on 100-foot-wide right of way. The National Environmental Policy Act review is pending. Construction is scheduled to begin in fall 2017, and the project is scheduled to be complete in spring 2018.

TVA is considering improvements to its transmission system that would provide power for growing load and increase power reliability in the Ider area.

TVA is proposing to build about five miles of single-circuit transmission line to power a new Sand Mountain Electric Cooperative substation in Ider. The line would begin at TVA’s Widows Creek Fossil Plant-Henagar 161-kV Transmission Line and proceed east to the new substation to be located southwest of the intersection of Highways 117 and 75 on the west side of Highway 75.

Four tap points and nine alternate line segments are under consideration. The line would be built on steel pole, single-circuit structures.

TVA will hold an open house on Thursday, August 6, 2015, to provide information, answer questions and receive comments about the proposed transmission project.

The project is expected to be in service fall 2017. Construction is scheduled to begin summer 2017. (Dates are subject to change. During projects of this magnitude, unexpected issues may arise, resulting in the need to adjust the schedule.)

Public involvement

TVA's process for siting new transmission projects is designed to allow public input at various stages. TVA is committed to working with area stakeholders to address concerns during various stages of the project. Comments received during the comment period will be used in reaching a decision on the proposed action.

TVA will hold an open house to discuss the proposed transmission project. Details are as follows:

Thursday, August 6, 2015
3:00 - 7:00 p.m.
Ider Missionary Baptist Church
Fellowship Hall
1078 Dogwood Dr.
Ider, Ala. 35981

TVA representatives will be available at the open house to provide information, answer questions and receive comments. Large maps showing the alternative locations for consideration will be available.

TVA is interested in receiving comments concerning how this project may affect the environment, historic properties or any other issues associated with this proposal. Any comments received, including names and addresses, will become part of the administrative record and will be available for public inspection.

If you have special needs, please contact Tanya Adams at least five days prior to the open house toll-free at (800) 362-4355.

If you cannot attend the open house but have questions or comments, contact Spencer Whittier. All written comments on this proposed action should be sent to TVA no later than September 4, 2015.


The map shows the network of alternative routes TVA is considering for the proposed transmission line. The map is also available below as a PDF file.

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. Floodplain and wetlands along with alternative routes are shown in the referenced map. The map illustrates how each alternative 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.
