What does Schedule 1 cost a year?

This plan is open only to households that qualify for it — the tariff is named “multi family”. It is real and currently offered, but not to everyone, so we leave it out of the plan-to-plan comparisons; the figures below are what it would cost a household that does qualify.
HouseholdUsesA monthPer yearWorks out to
Apartment

One or two people, no central air, no electric heat

4,866 kWh$58$69514.3¢ / kWh
Family home

Three or four people with central air conditioning

Home with an EV

Same house, plus an electric car charging overnight

13,103 kWh$153$1,83814.0¢ / kWh

Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.

off-peak10.18¢ up to 400 kWh13.13¢midnight–midnight, October–May

Plus a fixed charge of $14.66 per month.

Should you be on Schedule 1?

The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $164 and February about $81. That $83 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.

There is a usage cliff to watch. The first 400 kWh each month are billed at 11.5¢; past that line the rate steps up to 14.8¢ — 29% more for every unit after. The last kilowatt-hour of a heavy month is the expensive one, which is why cutting a little off a big month saves more than cutting the same amount off a small one.

Before a single kilowatt-hour moves, this plan charges $176 a year in fixed fees. On the apartment above that is 25% of the whole bill; on the house with a car charging in it, 10%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.
