Rate 5 - Residential Electric Heating Service

Does the hour matter on Rate 5 - Residential Electric Heating Service? No — one rate, every hour of the year.

  • off-peak26.72¢

There is no peak and no off-peak here: 26.72¢ per kilowatt-hour at 3am is the same as at 6pm, on a Sunday as on a Tuesday, in July as in January. Moving laundry or car charging to another time of day will not change this bill by a cent. What does change it is how much you use, and the fixed charge below, which you pay whether you use anything or not.

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.

Should you be on Rate 5 - Residential Electric Heating Service?

One rate, every hour of the year. That makes this plan predictable and nothing else: there is no cheap window to move laundry or car charging into, and no penalty for running the oven at six in the evening. Predictability is worth something if your schedule is not yours to control — but if it is, a flat rate is the one structure that guarantees you cannot benefit from it.

Before a single kilowatt-hour moves, this plan charges $285 a year in fixed fees. On the apartment above that is 18% of the whole bill; on the house with a car charging in it, 8%. 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.

Expect the bill to move with the calendar. The same family home costs about $317 in July and $183 in February — a $134 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.

How it compares to Connecticut Light & Power’s other plans

Measured against the other residential plans this utility files, a family home lands 1st cheapest of 3 — nothing else here beats it for that household.

Against Rate 1 - Residential Electric Service, which looks like the plan you land on by default, this one comes out $66 less per year (2%). We infer the default from the tariff structure rather than a flag in the data, so confirm it against your own bill before you switch.

Other Connecticut Light & Power plans

Who can be on Connecticut Light & Power’s Rate 5 - Residential Electric Heating Service?

Eligibility is not our judgement — it is written into the tariff Connecticut Light & Power filed. This is what that document says:

AVAILABLE for the entire electrical requirements of single-family residences, residential outbuildings, individual apartments, and general service use (i.e. common areas) in apartment buildings, where residential use constitutes over 50 percent of the metered energy. Service to a room or group of rooms which regularly separate cooking facilities shall be considered as service to a separate/individual apartment for metering and billing purposes. This Rate is also available for agricultural/farm customers who meet the CT definition of Agriculture. The over 50% residential use requirement does not apply to agricultural/farm customers.
