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.

Plus a fixed charge of $13 per month.

Should you be on 5?

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 26.9¢ a kWh; at the best hour, 9.1¢ — 3.0× 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 $65 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 $156 a year in fixed fees. On the apartment above that is 17% 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 $190 in July and $101 in February — a $90 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 Dominion Energy South Carolina’s other plans

Measured against the other residential plans this utility files, a family home lands 3rd cheapest of 5. The cheapest option, 7 (Residential Service Time-Of-Use Demand), would run about $221 a year less.

Against 8 (Residential Service), which looks like the plan you land on by default, this one comes out $190 less per year (11%). 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.
