Residential Service Time-of-Use with Critical Peak Pricing(R-TOU-CPP) Single Phase

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.

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 29.7¢ a kWh; at the best hour, 9.5¢ — 3.1× 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 $74 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 $176 a year in fixed fees. On the apartment above that is 20% of the whole bill; on the house with a car charging in it, 9%. 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 $185 in July and $99 in February — a $86 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.

Everything below stays inside Progress Energy Carolinas Inc (South Carolina). Your zone is set by where you live, not by anything you can pick, so a cheaper plan in a different zone is not an option you have.

Measured against the other residential plans this utility files, a family home lands 1st cheapest of 2 — nothing else here beats it for that household.

Against Residential Service (RES-55) Single Phase, which looks like the plan you land on by default, this one comes out $1 less per year (0%). 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.
