Semiannual Report – October 1, 2025 – March 31, 2026

We are pleased to present our report for the period October 1, 2025, to March 31, 2026.  In this semiannual period, our audit, evaluation, and investigative activities identified more than $41.7 million in questioned costs, recoveries, fees, and savings; and opportunities for Tennessee Valley Authority (TVA) to improve its programs and operations.  In our semiannual report feature, we discuss TVA’s role and challenges in Energizing the Valley’s and America’s Future.  TVA manages one of the nation’s largest public power systems and faces a variety of strategic, operational, and compliance risks as the energy landscape rapidly evolves.  As TVA continues to build new generation and integrate new nuclear technologies to increase capacity, it must also keep at the forefront the need to maintain high reliability and keep rates as low as feasible. The TVA OIG provides independent oversight with the vision to help make TVA better.  Through audits, evaluations, and investigations, the OIG identifies vulnerabilities, promotes efficiency, and addresses concerns involving fraud, waste, or misconduct.  By delivering objective analysis and actionable recommendations, the OIG supports TVA leadership in making informed decisions, enhancing transparency, and improving operations for the 10 million people of the Tennessee Valley.
