Audit of Westinghouse Material Escalation billings under Contract 65717

At the request of the Tennessee Valley Authority's (TVA) Supply Chain, we audited Westinghouse Electric Company LLC's billed and estimated remaining material escalation costs under Contract No. 65717. In summary, we determined Westinghouse overbilled a net $26,917 in escalation costs and overestimated the remaining material escalation costs by $137,408. In addition, we identified compensation terms in the contract that need to be clarified to reduce the potential for billing discrepancies.Westinghouse agreed with our findings that escalation costs were overbilled and overestimated. Accordingly, TVA management should ensure (1) TVA recovers $26,917 in overbilled escalation, and (2) the remaining escalation costs are billed in accordance with the contract. TVA and Westinghouse agreed the compensation terms need to be clarified, and the contract is being revised.May 2, 2012 - Review of Energy Efficiency and Demand Response - 2011-14061 We initiated a review of the effectiveness of Tennessee Valley Authority's (TVA) Energy Efficiency and Demand Response (EEDR) organization. We conducted this review because energy efficiency and demand reduction initiatives are important components of TVA's plan to meet future power needs in its service territory. The objectives of this review were to determine (1) how TVA measures the effectiveness of its energy efficiency and demand response programs and (2) if its goals in these areas are being met. We found EEDR (1) has contracted with an independent consultant to provide evaluation, measurement, and verification services and (2) achieved its planned energy efficiency and demand reduction for 2011 and only missed its planned demand reduction in 2009 and 2010 by 2 MW and 16 MW, respectively. The Green Power Switch program came close to achieving its goals for 2009 and 2010; however, it fell significantly short of its goal in 2011. This report was issued for informational purposes only.
