The Tennessee Valley Authority estimates the dispatch costs for coal and gas on a combination of elements including fuel pricing, physical operating characteristics, estimates of variable operating and maintenance costs, and other variables.

Our audit objectives were to determine if TVA has (1) adequate processes and procedures in place for awarding ED grants and (2) established performance metrics to determine if grant program objectives are met.
