Residential Time-of-Day Demand Service
Does the hour matter on Residential Time-of-Day Demand Service? No — one rate, every hour of the year.
- off-peak12.20¢
There is no peak and no off-peak here: 12.20¢ per kilowatt-hour at 3am is the same as at 6pm, on a Sunday as on a Tuesday, in July as in January. Moving laundry or car charging to another time of day will not change this bill by a cent. What does change it is how much you use, and the fixed charge below, which you pay whether you use anything or not.
What does Residential Time-of-Day Demand Service cost a year?
| Household | Uses | A month | Per year | Works out to |
|---|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $63 | $758 | 15.6¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $110 | $1,318 | 13.9¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $147 | $1,763 | 13.5¢ / 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
| Period | Rate | Applies when |
|---|---|---|
| off-peak | 12.20¢ | midnight–midnight |
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 Demand Service?
This plan bills a demand charge on top of the per-kWh rates: a fee tied to your single highest hour of the month. Two homes using the same total electricity can pay very different amounts if one of them runs the dryer, the oven, and the car charger at the same moment. We do not price demand charges yet, so treat every dollar figure on this page as a floor, not a total.
Before a single kilowatt-hour moves, this plan charges $164 a year in fixed fees. On the apartment above that is 22% 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 $148 in July and $85 in February — a $63 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.
Other Kentucky Utilities plans
Who can be on Kentucky Utilities’s Residential Time-of-Day Demand Service?
Eligibility is not our judgement — it is written into the tariff Kentucky Utilities filed. This is what that document says:
RTOD-Demand 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-Demand and RTOD-Energy 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.
