What a humidifier costs here
Across 17 plans priced in Texas, a humidifier adds $7.87 to $20.88 a year — $0.66 to $1.74 a month. The median plan puts a humidifier at $14.15 a year.
Cheapest for a humidifier: RS - TOD, El Paso Electric Co (New Mexico). Dearest: Residential LSP POLR, Sharyland Utilities LP.
Those 116 kWh are billed at 6.8¢–18.0¢, against a 12.7¢ whole-bill average on the median plan: they land in the last tier the household reaches, so the average rate understates them by up to 5.3¢ per kWh.
What Texas homes use
EIA's 2020 residential survey found 116 kWh a year across 138 sampled homes that run one, 16% under the national 139 kWh. The middle half spans 14 kWh to 133 kWh, so a humidifier varies by 120 kWh between one household and another.
Portable and whole-home humidifiers. That average covers homes with a humidifier — 13% of homes here, against 24% nationally.
That makes a humidifier about 1% of the electricity a Texas home uses. The remaining 13,324 kWh is what a humidifier is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
By provider
