Why your bill is rising
Tennessee is in the PJM Interconnection footprint, and PJM capacity prices for the next delivery years have already cleared at auction. These are contract results, not forecasts — they flow into residential bills as a capacity charge, on top of whatever fuel and distribution costs do.
Only part of Tennessee is in PJM: Largely TVA; retail choice minimal.

Can you switch plans in Tennessee?
No. Tennessee's residential electricity market does not offer retail supplier choice, so you cannot cut the bill by switching plans. Largely TVA; retail choice minimal.
What you can do instead: cut the usage side of the bill. See what each appliance actually costs to run at Tennessee rates in our cost-to-run guides, and target the biggest loads first.
