What a dehumidifier costs here
Across 17 plans priced in Texas, a dehumidifier adds $81.43 to $215.52 a year — $6.79 to $17.96 a month. The median plan puts a dehumidifier at $146.80 a year.
Cheapest for a dehumidifier: RS - TOD, El Paso Electric Co (New Mexico). Dearest: Residential LSP POLR, Sharyland Utilities LP.
Those 1,197 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 1,197 kWh a year across 49 sampled homes that run one, 1.20× the national 999 kWh. The middle half spans 241 kWh to 1,965 kWh, so a dehumidifier varies by 1,724 kWh between one household and another.
Portable and whole-home dehumidifiers. That average covers homes with a dehumidifier — 4% of homes here, against 17% nationally.
That makes a dehumidifier about 9% of the electricity a Texas home uses. The remaining 12,243 kWh is what a dehumidifier is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
By provider
On each Texas provider's cheapest plan: El Paso Electric Co (New Mexico), $81.43; City of Lubbock, Texas (Utility Company), $85.20; City of San Antonio, Texas (Utility Company), $115.36; El Paso Electric Co, $120.89; Austin Energy, $147.36; Sharyland Utilities LP, $160.20.
Sharyland Utilities LP charges $78.77 a year more than El Paso Electric Co (New Mexico) on RS - TOD for the same 1,197 kWh.
Light and heavy use of a dehumidifier
