Off-peak electricity typically costs about $0.05-$0.18 per kilowatt-hour (kWh), with many time-of-use plans averaging near $0.10-$0.12 per kWh before fixed monthly charges. The exact off-peak electricity cost depends on the utility, region, plan hours, and whether the quoted rate includes delivery and other charges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Off-peak energy rate | $0.05/kWh | $0.10-$0.12/kWh | $0.18/kWh | Typical plan range; some areas fall outside it |
| Monthly off-peak usage | $15 | $40 | $90 | At 300-750 kWh, excluding fixed fees |
| Monthly plan or customer charge | $0 | $10-$20 | $30+ | Depends on utility and tariff |
| Peak-hour energy rate | $0.15/kWh | $0.25-$0.35/kWh | $0.50+/kWh | May apply during weekday demand periods |
What households pay for off-peak electricity per kWh
For a residential time-of-use plan, a practical planning range is $0.05-$0.18 per kWh for off-peak energy. A middle-of-the-range estimate is around $0.10-$0.12 per kWh. At that rate, using 500 kWh during off-peak hours costs about $50-$60 for the energy portion of the bill.
Some utilities advertise a lower generation rate, but the final bill can also include delivery charges, a customer fee, taxes, and public-benefit assessments. If delivery is billed per kWh, the effective rate can be several cents higher than the advertised energy price. A bill may also combine fixed monthly charges with separate peak, off-peak, and shoulder-period rates.
For budgeting, compare the all-in off-peak charge on the bill, not just the advertised supply rate. Rates below $0.05 per kWh can occur in certain plans or seasons, while high-cost markets and plans with delivery included may exceed $0.18 per kWh. Assumptions: Residential service, standard time-of-use plan, and no unusually large fixed fees.
What utility bills include beyond the off-peak rate
A time-of-use quote can contain several charges, and not all of them fall when usage moves to off-peak hours. The table shows common residential bill components; actual descriptions and billing methods vary by utility.
| Charge | Typical amount | How it affects the estimate | Where to check |
|---|---|---|---|
| Off-peak energy | $0.05-$0.18/kWh | Multiplies by kWh used during off-peak hours | Rate schedule or bill detail |
| Peak energy | $0.15-$0.50+/kWh | Raises cost for use during designated peak windows | Time-of-use rate table |
| Delivery charge | $0.02-$0.12/kWh, sometimes fixed | May apply at every hour or vary by period | Delivery or distribution line items |
| Customer charge | $5-$30+/month | Remains due even if usage shifts to off-peak | Monthly service charge |
| Taxes and assessments | Often 2%-15% of applicable charges | May be calculated on energy, delivery, or total bill | Tax and adjustment lines |
For example, 400 off-peak kWh at $0.09 each equals $36 in energy charges. If delivery adds $0.05 per kWh, that adds $20, before fixed charges and taxes. Where a utility publishes an “all-in” rate, verify whether it includes delivery, taxes, and monthly service charges before comparing it with a competing plan.
Fixed fees do not disappear when appliances run overnight. The household may lower variable charges while paying the same customer charge, so the total bill reduction is usually smaller than the percentage difference between peak and off-peak rates.
How rate windows and household use change the price
Utilities define off-peak hours in their own tariffs. Many residential plans place lower rates overnight, but some also include weekends or midday hours. A common schedule might set off-peak from 9 p.m. to 7 a.m., while another utility may use 11 p.m. to 6 a.m. and charge a shoulder rate in between. Those examples are illustrative, not universal schedules.
Season and weekday can change the tariff. Summer peak periods may run longer because air-conditioning demand is high; winter schedules may emphasize morning and evening heating loads. Some utilities classify hours by season, while others adjust prices by demand or use a critical-peak event rate on a limited number of days.
The savings depend on both the rate gap and the amount of energy shifted. Moving 100 kWh from a $0.30 peak rate to a $0.10 off-peak rate saves $20 before added fees. Moving the same usage from $0.16 to $0.13 saves only $3. A household that cannot shift much consumption may pay more on a time-of-use plan if its peak usage outweighs the discount.
Check the exact weekday, weekend, and seasonal hours before estimating savings. A smart meter or utility portal can show usage by hour; reviewing at least one full billing cycle helps identify whether major loads occur during expensive periods.
Lower the bill by shifting appliances and charging
The most controllable expense is usually energy that can be scheduled without changing how the home operates. Dishwashers, laundry equipment, water heaters, pool pumps, and electric-vehicle charging can often be delayed to qualifying off-peak hours. A timer or appliance delay-start feature can help, but the utility’s published time window should guide the schedule.
Electric-vehicle charging can be a substantial opportunity. A vehicle using 250 kWh per month for charging costs $25 at $0.10 per kWh, compared with $75 at $0.30 per kWh, before any charging fees or plan charges. Actual use depends on mileage and vehicle efficiency. A utility may also offer a separate EV rate, but it may require a dedicated meter or approved charger.
Heating and cooling need a more careful comparison. Pre-cooling or pre-heating a home before a peak window can reduce use during expensive hours, but it does not guarantee savings if the system runs longer overall. Avoid shifting essential medical equipment or safety-critical loads, and follow appliance and battery manufacturer instructions.
Measure the shifted kWh against the rate difference before buying equipment. If a timer costs $30 and saves $5 monthly, simple payback is about six months; if the schedule yields only $1 in monthly savings, the purchase may not pay back for years.
How off-peak rates differ across U.S. regions
Electricity prices vary widely by state, utility territory, fuel mix, grid costs, and local regulation. An off-peak rate near $0.06-$0.10 per kWh is more plausible in some lower-cost regions, while rates of $0.12-$0.20 or more can occur in higher-cost areas. These are broad planning ranges, not state guarantees; individual utility tariffs can sit outside them.
Urban and rural location alone does not determine the price. A rural customer may pay a higher delivery charge because fewer customers share network costs, while a city customer may have a higher supply rate or local taxes. Climate also affects the benefit: air-conditioning-heavy homes may have sizable summer peak use, whereas homes with electric heating may face winter morning or evening peaks.
Compare the same items when checking local offers: off-peak hours, peak and shoulder rates, delivery charges, seasonal changes, minimum bills, and monthly fees. A plan with an attractive off-peak rate can be more expensive if its peak rate is high during hours when the home uses air conditioning, cooking equipment, or space heating.
Use the local utility tariff as the final authority rather than a national average. For a rough comparison, calculate each plan using the home’s hourly usage and the relevant seasonal rate schedule; a monthly total from a bill calculator is more useful than comparing one advertised price.
Off-peak plans compared with flat-rate electricity
A flat-rate plan charges roughly the same energy price throughout the day, while a time-of-use plan varies the rate by hour. A flat rate can suit a household with substantial daytime or evening use that cannot be shifted. A time-of-use plan can work better when charging, laundry, or other flexible loads can move to low-price hours.
Consider a home that uses 800 kWh per month. At a flat $0.18 per kWh, its energy charge is $144. Under a time-of-use plan, suppose 500 kWh is off-peak at $0.10 and 300 kWh is peak at $0.30. The energy charge is $140, only $4 lower before considering different fixed fees and delivery charges. If peak use rises to 400 kWh and off-peak use falls to 400 kWh, the time-of-use energy charge becomes $160.
To compare fairly, use actual hourly data where available and include at least 12 months if the utility changes rates by season. For households without interval data, estimate the share of use that can realistically shift, rather than assuming all overnight or weekend consumption qualifies.
Time-of-use pricing is not automatically cheaper than a flat rate. The useful question is whether the household’s likely savings on shifted consumption exceed any higher peak charges, enrollment fees, or added monthly charges.
Three household examples show the monthly price range
These examples isolate electricity charges to illustrate how usage and rate mix affect the bill. They exclude taxes and fixed fees unless noted; utility delivery charges may raise totals.
| Usage scenario | Off-peak usage and rate | Peak usage and rate | Estimated energy total |
|---|---|---|---|
| Small apartment | 250 kWh at $0.09 = $22.50 | 150 kWh at $0.25 = $37.50 | $60 |
| Typical all-electric home | 500 kWh at $0.10 = $50 | 400 kWh at $0.30 = $120 | $170 |
| Home with EV charging | 750 kWh at $0.08 = $60 | 450 kWh at $0.32 = $144 | $204 |
In the apartment example, the low off-peak rate contributes $22.50, but peak use still accounts for more than half of the energy charge. For the all-electric home, shifting 100 kWh from peak to off-peak would reduce energy charges by $20 at the stated rates. The EV example assumes most charging is scheduled overnight; charging outside the window would cost more.
Use the examples as calculation models, not as expected local bills. Replace the example rates with the utility’s current schedule and use the home’s actual kWh by hour for a reliable estimate.
Questions that change an off-peak electricity estimate
Does off-peak pricing apply on weekends?
Sometimes. Some tariffs offer off-peak prices all weekend, while others use weekday and weekend schedules or retain peak periods on summer afternoons. The tariff’s schedule determines which hours qualify; the term “off-peak” does not have one national definition.
Can delivery charges erase the discount?
They can reduce the savings, especially when delivery is charged at the same per-kWh rate all day. For example, a $0.08 energy discount is only a $0.08 total saving if delivery is unchanged, not a saving on the full bill. Fixed monthly charges remain payable regardless of when electricity is used.
Is a special meter or enrollment required?
Some utilities apply time-of-use rates through an existing smart meter, while others require enrollment or an additional meter for a separate EV tariff. Ask whether installation, account, or minimum-bill charges apply and whether the plan can be changed later.
What should be compared before switching plans?
Compare the off-peak and peak rates, exact hours, seasonal periods, delivery method, monthly charges, contract terms, and any cancellation fee. Review usage data before enrolling, especially if the home relies on electric heating or air conditioning during likely peak windows.
A dependable estimate uses the full tariff and the household’s hourly pattern. The advertised off-peak price is only one part of the cost; the peak window and bill structure determine whether the plan lowers the total.
