CEMC: questions

Does CEMC have peak hours?

Not on the plans modeled here: RS charges the same price per kWh at every hour, so when you use power does not change the bill.

How CEMC’s plans work

RS (Residential Rate). One price per kWh at every hour: 11.2¢ in July and 11.0¢ in January. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $39.00 a month.

Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.

As a cross-check, CEMC billed its residential customers an average of 12.99¢ per kWh in 2024 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for Tennessee’s price change since.
