Why is it like this in Tennessee?

Tennessee's electricity is supplied almost entirely by TVA, which serves roughly 10 million customers across seven states. TVA executed a 5.25% rate increase in August 2024 — its largest in more than a decade — and has directed roughly 90% of its $4.6 billion capital budget toward fossil fuel generation, tying rate stability to natural gas prices. At current prices, gasoline and electricity are close in Tennessee, with electricity holding a clear per-mile advantage over gasoline in Tennessee at the January 2026 baseline — the TVA rate increase has narrowed the gap somewhat, but electric mode remains meaningfully cheaper.
