TVA’s Transmission System

TVA owns and operates one of the largest and most reliable transmission systems in North America, serving some 9 million residents in an 80,000-square-mile area spanning portions of seven states. TVA’s transmission system moves electric power from the generating plants where it is produced to distributors of TVA power and to industrial and federal customers across the region. In fiscal 2009, the TVA system delivered its tenth year in a row of 99.999 percent reliability. (Read more on system facts and key managers.)

TVA provides transmission service on a nondiscriminatory, as-available basis to other qualified power providers requiring power transfers out of or through the TVA system. TVA also provides interconnection services to independent power producers consistent with sound reliability practices.
