What does Residential Time-of-Day Energy Service cost a year?

HouseholdUsesA monthPer yearWorks out to
Apartment

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

4,866 kWh$101$1,21425.0¢ / kWh
Family home

Three or four people with central air conditioning

Home with an EV

Same house, plus an electric car charging overnight

13,103 kWh$239$2,86921.9¢ / kWh

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.

What you actually pay

PeriodRateApplies when
peak36.89¢6am–10am, 6pm–10pm, November–March; 1pm–5pm, April–October
off-peak17.73¢10pm–6am, 10am–6pm, midnight–midnight, November–March; 5pm–1pm, midnight–midnight, April–October

Plus a fixed charge of $0.45 per day — so longer months cost more before you use a single kWh.

Should you be on Residential Time-of-Day Energy Service?

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 36.9¢ a kWh; at the best hour, 17.7¢ — 2.1× 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 midnight is about $70 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 $164 a year in fixed fees. On the apartment above that is 14% of the whole bill; on the house with a car charging in it, 6%. 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 $247 in July and $150 in April — a $97 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 Kentucky Utilities’s other plans

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, 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.

Other Kentucky Utilities plans

Who can be on Kentucky Utilities’s Residential Time-of-Day Energy Service?

Eligibility is not our judgement — it is written into the tariff Kentucky Utilities filed. This is what that document says:

RTOD-Energy shall be available as an option to customers otherwise served under rate schedule RS. 1) Service under this rate schedule is limited to a maximum of five hundred (500) customers taking service on RTOD-Energy and RTOD-Demand combined that are eligible for Rate RS. Company will accept customers on a first-come-first-served basis. 2) This service is also available to customers on rate schedule GS (where the GS service is used in conjunction with an RS service to provide service to a detached garage and energy usage is no more than 300 kWh per month) who demonstrate power delivered to such detached garage is consumed, in part, for the powering of low emission vehicles licensed for operation on public streets or highways.

Shortened — the clause runs longer in the filing. Quoted from the filed tariff. Your utility decides eligibility, not us; check with them before you switch.
