Tennessee Valley Authority accomplishes a line uprating and avoids clearance issues on a 500-kV transmission line with a high-capacity conductor. The Tennessee Valley Authority (TVA) is no stranger to 500-kV transmission lines or the relentless need to modify existing power lines to meet the energy demands of the region. But, when the utility needed to increase the ampacity rating of its 500-kV Pin Hook-Wilson transmission line to meet load growth, the engineering department was forced to think outside the box.
