What this means in Mississippi

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

Why Mississippi pays what it does

Mississippi 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 16.16 cents, Mississippi ranks 24 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 dehumidifier on the same schedule, in the cheapest and dearest states:

Lowering the number in Mississippi

• Set the humidistat to 50 percent. Chasing 40 often doubles runtime for no additional benefit.
• Fix the water before drying the air. Grading, gutters and a vapour barrier are one-time costs; a dehumidifier is 500 W forever.
• Use the continuous drain hose. A full bucket stops the unit and the humidity climbs back.
• Close basement windows in summer. Warm humid air condensing on cool surfaces is the load you are paying to remove.
• Clean coils and filter. Restricted airflow extends every cycle.

Offsetting it with solar in Mississippi

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 16.16 cents rather than the national 18.44 cents, the same array is worth less here than the national payback figures suggest.

Long runtime is what makes this expensive to run on solar, not the draw. Basement units run through the night when there is no sun. Full sizing, including battery and inverter requirements, is on the solar sizing page for this appliance.

Questions people actually ask

Run time is the variable you control, and the hours table above shows exactly what each hour costs. Since Mississippi is regulated, shopping for a supplier is not an option, so usage is the lever.[/hed_faq]
