TRC Environmental Corporation

We performed an audit of costs billed to the Tennessee Valley Authority (TVA) by TRC Environmental Corporation (TRC) for energy efficiency services provided in support of TVA’s EnergyRight® Services for Business and EnergyRight® Services for Industry under Contract No. 15361. Our audit objective was to determine if the costs billed to TVA were in accordance with the contract terms.  Our audit scope included approximately $43.56 million in costs billed to TVA from January 1, 2023, through March 31, 2025.

In summary, we determined TRC billed incentives in accordance with the contract terms.  However, we determined TRC overbilled TVA $251,352 in time and material costs.  Specifically, we determined:

• TRC overbilled $242,985 in labor costs, including (1) $230,831 due to incorrect rate escalation, (2) $9,230 in time and material rates that exceeded the contract rates, and (3) $2,924 for subcontracted personnel in excess of the actual costs paid.  
• TRC overbilled an estimated $8,367 in travel costs, including (1) $4,792 in ineligible travel booking fees and (2) an estimated $3,575 in overbilled mileage costs.  In addition, meals and incidental costs and lodging costs associated with travel were not billed in accordance with the contract, resulting in a net immaterial overbilling.
