MAKING TVA BETTER
The TVA Office of Inspector General performs a crucial mission by providing independent and objective reporting to the TVA Board, the Congress, and other stakeholders.
For more than 35 years, the TVA OIG has stayed committed to providing an independent analysis of TVA operations and programs to help identify more efficient and effective ways to do business and to prevent and detect fraud, waste, and abuse. In those years, we have seen many changes in TVA and TVA OIG. One constant is the focus on making TVA better by helping TVA save or recover money, reduce risks, and improve operations and working to bring justice to those who commit fraud. Making TVA better is a mutual purpose we share with TVA management, employees, and the TVA Board. It is important to the 10 million people of the Tennessee Valley served by TVA that we approach our work with that purpose every day.
