Residential Time-of-Day Bundled Ohio Power Rate Zone (RS-TOD)

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 18.7¢ a kWh; at the best hour, 14.9¢ — 1.3× 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 midnight to 7am is about $14 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 $185 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 $199 in August and $116 in February — a $83 spread driven by heating and cooling far more than by anything you chose. Budget against the August figure, not the average, and a summer bill stops being a surprise.

Measured against the other residential plans this utility files, a family home lands 6th cheapest of 8. The cheapest option, Residential Service Demand Metered Ohio Power Rate Zone, Bundled (RSDM), would run about $1,072 a year less.

Against Residential Service Ohio Power Rate Zone (RS), which looks like the plan you land on by default, this one comes out $709 more per year (67%). 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.
