Figure	What It Measures
5.25%	TVA wholesale power rate increase in 2024, the largest in 16 years
4.5%	TVA base rate hike heading into 2026
HB 1847	New TN law (signed May 7, 2026): 50+ MW centers must fund their own infrastructure
Passed	TVA data-center rate class approved Aug 20, 2026, effective Oct 1. ~10% phased over 3 years

TVA has publicly stated it is a priority to ensure “serving new data centers does not create rate pressure on other electric customers.” On August 20, 2026, the board unanimously approved a data-center rate class, effective October 1, phasing in roughly 10% over three years. No cost-of-service study was conducted, and the rate carries no stranded-asset or early-termination clauses. The state’s legislative response, HB 1847, attempts to address infrastructure costs going forward but applies only to facilities drawing 50+ MW. Fisk’s 30 MW proposal would not be covered.
