What North Carolina homes use

EIA's 2020 residential survey found 588 kWh a year across 148 sampled homes that run one, near the national 570 kWh. The middle half spans 370 kWh to 711 kWh, so a separate freezer varies by 341 kWh between one household and another.

A standalone chest or upright freezer, not the freezer compartment of a fridge. That average covers homes with a separate freezer — 31% of homes here.

That makes a separate freezer about 5% of the electricity a North Carolina home uses. The remaining 11,910 kWh is what a separate freezer is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
