The Office of the Inspector General included a review of Revenue Billing's invoice preparation process for local power companies (LPC) on its annual audit plan because of the significance of this source of revenue to TVA. We audited the invoice preparation process for the period April 1, 2011, through July 31, 2013, to determine if: (1) wholesale invoices were calculated correctly, (2) controls to prevent/detect invoice errors were adequate, and (3) Oracle Utilities had appropriate/adequate information technology general and application level controls.Our audit of the invoice preparation process for LPCs during the period, found: (1) wholesale invoices were calculated correctly, (2) controls to prevent/detect invoice errors were adequate, and (3) Oracle Utilities had appropriate/adequate IT general and application level controls. However, we identified minor issues where changes could strengthen and/or improve the revenue billing process and decrease the likelihood of errors or adjustments.
