What this means in Tennessee

This appliance runs on much the same schedule regardless of climate, so the figure above is a reasonable year-round estimate for Tennessee. What changes it is your own usage pattern rather than the weather.

Why Tennessee pays what it does

Tennessee is a regulated market, so your utility is the only supplier and the rate is set through the state commission rather than by competition. Pricing tends to be steadier than in deregulated states, and there is no switching decision available. The levers are all on your side of the meter.

At 14.47 cents, Tennessee ranks 12 of 51 from cheapest to most expensive. The Southeast regional average is 16.16 cents. Roughly half of any residential bill is transmission and distribution rather than generation, which is why rates keep climbing even when fuel prices fall.

How this compares across the country

The same hot tub on the same schedule, in the cheapest and dearest states:

Lowering the number in Tennessee

• Replace a waterlogged cover. A saturated cover conducts heat instead of blocking it, around the clock.
• Drop the setpoint a few degrees. Every degree reduces the gradient the heater fights.
• Use economy or sleep mode between uses. Cheaper than holding full temperature, without the long reheat of switching off.
• Shelter it from wind. An exposed tub loses heat far faster.
• Do not switch it off between weekly uses. Reheating from cold costs more than holding temperature.

Offsetting it with solar in Tennessee

This load uses about 6.00 kWh a day. Covering that would take roughly 5 standard 400 W panels at typical sun hours, an array of about 2.00 kW. Because it offsets electricity worth 14.47 cents rather than the national 18.44 cents, the same array is worth less here than the national payback figures suggest.

The heater runs on its own schedule including overnight, which makes this a storage problem rather than a panel problem. Full sizing, including battery and inverter requirements, is on the solar sizing page for this appliance.
