What does RETC cost a year?

HouseholdUsesPer yearWorks out to
Apartment

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

4,866 kWh$71014.6¢ / kWh
Family home

Three or four people with central air conditioning

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 RETC?

This is a time-of-use plan, which means the clock decides your bill as much as the meter does. At the worst hour you pay 21.8¢ a kWh; at the best hour, 7.5¢ — 2.9× apart for identical electricity.

That gap is worth real money only if you can move load into it. Every kilowatt-hour a day you shift from 6am to 1am is about $52 a year. A dishwasher run is roughly 1.5 kWh; an EV commute charge is 8 to 12. If your day is fixed — you are home in the evening and the air conditioner runs when it runs — a plan like this costs you more, not less.

Before a single kilowatt-hour moves, this plan charges $168 a year in fixed fees. On the apartment above that is 24% of the whole bill; on the house with a car charging in it, 11%. 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 $142 in July and $78 in February — a $64 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 Duke Energy Carolinas’s other plans

Measured against the other residential plans this utility files, a family home lands 6th cheapest of 30. The cheapest option, RT (Residential Service Time of Use), would run about $191 a year less.

Against Residential Service (RES-55) Single Phase, which looks like the plan you land on by default, this one comes out $349 less per year (22%). 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.
