1(M) Residential Anytime Service Rate
When does peak hit on Union Electric Co - (MO)’s 1? The hour never matters here — only the season. Rates peak June–September.
- peak14.50¢
- off-peak10.12¢
What does 1 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 | $56 | $672 | 13.8¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $103 | $1,240 | 13.1¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $134 | $1,606 | 12.3¢ / 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 |
|---|---|---|
| peak | 14.50¢ | midnight–midnight, June–September |
| off-peak | 10.12¢ up to 750 kWh7.05¢ | midnight–midnight, October–May |
Plus a fixed charge of $9 per month.
Should you be on 1?
The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $168 and February about $69. That $99 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.
Before a single kilowatt-hour moves, this plan charges $108 a year in fixed fees. On the apartment above that is 16% of the whole bill; on the house with a car charging in it, 7%. 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.
How it compares to Union Electric Co’s other plans
Measured against the other residential plans this utility files, a family home lands 2nd cheapest of 4. The cheapest option, 1(M) Residential Overnight Saver Service, would run about $14 a year less.

Who can be on Union Electric Co’s 1(M) Residential Anytime Service Rate?
Eligibility is not our judgement — it is written into the tariff Union Electric Co filed. This is what that document says:
This rate is applicable to all normal residential service supplied by the Company to individually metered residences and apartments consisting of one or more rooms for the use of one or more persons as a housekeeping unit with space for eating, living and sleeping, and permanent provisions for cooking and sanitation.

If this is new to you
- Tiered billing for electricity: why the last kWh costs more
A cheap allowance, then a cliff. Where the cliff sits is the whole game.
- Should you switch to a time-of-use electricity plan?
A wide peak-to-off-peak gap is a lever, not a saving. Levers need something to move.
- Why is my electric bill so high in summer?
Usually three causes at once, and only one of them is your air conditioner.
- Why is my electric bill so high? Seven causes, in the order to check them
Seven causes, ranked by how often they are the answer. Only two are about using more.
