The Tennesse Valley Authority (TVA) has implemented a comprehensive study of their hydroelectric plants in order to extend their service life for the next 50 years into the 21st century. The scope of this study was to assess present conditions of equipment, review prior assesments, consider possible system modifications, recommend modifications, provide a cost estimate and implement a schedule, and develop a final report. The project's goals were to maintain flood control and navigation channels and provide cheap hydroelectric power generation. From this study several potential benefits are hoped to be realized. The power plant managers will have a comprehensive listing of equipment and system assessment, funding to conduct special studies, and be able to focus corporate needs on the hydroelectric system. The power system will benefit by providing an engineering analysis at existing and potential problems. This article also gives general advice on the management of a study of this scope.
