Solar Purchased Power Agreements

As part of our annual audit plan, we audited the Tennessee Valley Authority's (TVA) utility-scale Solar Purchased Power Agreements (PPA). Our audit objectives were to determine if TVA has (1) approached Solar PPAs to better understand the industry and market trends being developed prior to entering into multiple agreements and (2) developed Solar PPAs to recognize positive financial value earlier in the term of the PPAs. The scope of our review was utility-scale solar PPAs in place as of December 31, 2020. We found TVA had (1) taken a measured approach to solar PPAs to better understand the industry and market trends and (2) generally developed solar PPAs to recognize positive financial value or breakeven.
