The TVA OIG Releases Its Spring 2015 Semiannual Report to Congress

The TVA OIG is releasing its Spring 2015 Semiannual Report to Congress – a report required by law twice a year. This edition’s theme, “Building a Better TVA…Together,” focuses on the OIG’s commitment to provide an independent view of the effectiveness of TVA operations and challenges ahead as well as the importance of working collaboratively with TVA management to identify the best solutions to address those challenges. In the feature article of this report, the OIG provides an overview of TVA’s strategic initiatives and actions being undertaken to address TVA’s challenges. The OIG also discusses the challenges it sees ahead for TVA and how its work can help TVA navigate challenges in the areas of sustaining efforts to improve organizational health; maintaining assets while controlling organizational spending; ensuring cyber-security on critical assets; and improving overall major project execution. In this semiannual period covering October 1, 2014 through March 31, 2015, the OIG’s audit, evaluation, and investigative activities identified nearly $11 million in funds that could be put to better use, questioned costs, recoveries, savings and penalties as well as opportunities for TVA to improve its programs and operations.

Adequacy of the Invoice Approval Process

We audited the adequacy of the Tennessee Valley Authority’s (TVA) invoice approval process. Our objectives were to (1) assess TVA's policies and procedures related to the review and approval of invoices, (2) determine compliance with applicable policies and procedures, and (3) determine if TVA's invoice approvers have adequate information (including clear contractual compensation provisions and sufficient invoice detail) to effectively perform their role. The scope of our audit included Supply Chain nonreceiving contracts/POs with fiscal year 2013 payments totaling $3.3 billion. In summary, we found policies and procedures were not being followed to ensure effective review and approval of supplier invoices. Specifically, our review of 143 invoices, totaling $184,339,674, found inadequate reviews were performed on 104 invoices (or 73 percent). We determined several potential underlying causes for why effective invoice reviews were not performed and recommended TVA management take actions to address the causes. TVA management generally concurred with our findings and stated they would take action to address our recommendations. Click here to read this report…

Message from the IG


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. The OIG does this through its audit, evaluation and investigative activities. By statute it is charged with promoting economy and efficiency throughout TVA while preventing and detecting fraud, waste, and abuse affecting TVA. TVA employees, contractors, and the public can help the TVA OIG fulfill its mission and make a difference at TVA by reporting any suspicions about fraud, waste and abuse to the OIG hotline system, known as Empowerline.
