Preventive maintenance (PM) includes tasks carried out on a predetermined interval to reduce the likelihood of a failure. Due to the importance of PM on the reliable operation of assets and as a result of findings identified related to nuclear and coal PM in previous evaluations, we initiated an evaluation of the TVA's transmission PM. The objective of our evaluation was to determine if transmission PM was performed in accordance with established schedules and, if not, what effects the deviations had.

However, we also identified an employee engagement risk related to a relationship issue with one manager.

TVA has both fixed and variable costs that it must recover. Since fuel and purchased power cost can fluctuate significantly with changes in weather and shifts in global supply and demand, TVA recovers these variable costs through a monthly fuel cost adjustment (FCA). The TVA Act assigns rate setting duties to the TVA Board of Directors (Board). The rates approved by the Board include the formula used to calculate the monthly FCA, which represents approximately one-third of the wholesale rate.

At the request of the Tennessee Valley Authority (TVA) Supply Chain's former Director of Sourcing, we audited costs billed to TVA by ScottMadden, Inc.

Under the contracts, ScottMadden provided consulting services that included, but were not limited to, financial management and business management services. Our audit scope included about $19.6 million in costs that ScottMadden billed to TVA from January 1, 2012, through December 31, 2015, under the three separate contracts.
