TVA Transmission Projects

As Power Demand Grows, So Does the Need for New Transmission Lines

As demand for electricity grows, so, too, does TVA’s need to build new transmission lines and substations that will connect even more power from our generating plants to local power companies to the 10 million people who live and work in the Tennessee Valley region. TVA’s transmission siting process is comprehensive and looks for solutions that will have the least overall impact on people, communities and the environment.

A Positive Impact

Reliable power is something we all depend on. It allows our homes, businesses, schools and hospitals to operate. New transmission lines and substations benefit the greater community, because they help ensure that TVA can continue to provide affordable, reliable power across the region. Additionally, the power TVA generates – and that travels through our 16,400 miles of transmission lines – helps bring economic development and prosperity to the region.

About TVA's Transmission Siting Process

TVA uses a comprehensive siting process that places transmission lines and substations in locations that satisfy transmission needs, meet technical requirements and consider the impacted area. The process includes:

Transmission Planning

Analyzing transmission system changes, evaluating multiple project alternatives and identifying the best overall transmission solution

Transmission Siting

Defining the specific study area, identifying feasible route options, engaging the public for feedback, communicating directly with landowners and selecting the route that has the least overall impact

Environmental

Identifying environmental/cultural impacts of route options, minimizing or mitigating potential impacts and ensuring compliance with regulations

Survey

Contacting landowners before survey work and conducting field surveys to determine the centerline

Realty

Conducting property title research, engaging licensed property appraisers, preparing legal documents for acquisition and presenting the offer to landowners

Right of Way

Identifying and installing access, clearing vegetation and performing site restoration

Construction

Following selected routes and access roads to minimize impact, constructing lines and structures with precision, and arranging engineering verification.
