What a separate freezer costs here

Across 39 plans priced in Massachusetts, a separate freezer adds $43.08 to $152.40 a year — $3.59 to $12.70 a month. The median plan puts a separate freezer at $111.96 a year.

Cheapest for a separate freezer: Greater Boston Residential R-1 (A1), NSTAR Electric Company. Dearest: Cape Cod Residential Rate (R-1), NSTAR Electric Company.

Those 450 kWh are billed at 9.6¢–33.9¢, against a 26.0¢ 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 7.8¢ per kWh.

What Massachusetts homes use

EIA's 2020 residential survey found 450 kWh a year across 124 sampled homes that run one, 21% under the national 570 kWh. The middle half spans 276 kWh to 546 kWh, so a separate freezer varies by 271 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 — 22% of homes here, against 33% nationally.

That makes a separate freezer about 6% of the electricity a Massachusetts home uses. The remaining 6,787 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.

Light and heavy use of a separate freezer

A household in the lighter quarter runs a separate freezer for 276 kWh a year and pays $26.40 on the cheapest plan. One in the heavier quarter runs it for 546 kWh and pays $52.32 — $25.92 more for a separate freezer on the same tariff.
