The time of day can significantly impact electric costs. Time-of-use plans, offered by many utility companies, charge variable rates based on peak and off-peak hours. Peak hours, when demand is highest, typically occur when most people are at home, such as early morning and evening. During these times, electricity rates are highest. In contrast, off-peak hours, such as weekends and holidays, offer lower rates due to reduced demand. By adjusting energy usage to off-peak hours, consumers can reduce their electric bills and contribute to a more sustainable energy future.
| Characteristics | Values |
|---|---|
| Time of Day with Lowest Electricity Rates | Off-peak hours, usually 10:00 pm-5:00 am, weekends, and holidays |
| Time of Day with Highest Electricity Rates | Peak hours, usually 4-9 pm or 5-8 pm, especially during summer weekdays |
| Factors Affecting Electricity Rates | Supply and demand, fuel costs, number of power plants needed |
| Impact of Time of Day on Electricity Costs | Running appliances during off-peak hours can save money; using energy during peak hours will cost more |
| Ways to Reduce Electricity Costs | Shift energy-intensive tasks to off-peak hours, weekends, or holidays; use scheduling functions on appliances; set air conditioner temperature above 78 degrees |

What You'll Learn
Peak hours
During peak hours, it is best to avoid using energy-intensive appliances, such as dishwashers, washing machines, and dryers. Many of these appliances have scheduling functions, allowing you to set them to run during off-peak hours. If you have an electric vehicle, you can also take advantage of lower rates by charging it overnight during off-peak periods.
Time-of-use (TOU) plans offered by utility companies can help you manage your energy costs. These plans offer lower rates during off-peak and super off-peak periods, which are typically weekends, holidays, and overnight hours. By shifting your energy usage to these lower-demand periods, you can take advantage of lower rates and reduce your overall energy costs.

Off-peak hours
Some utility companies also offer "super off-peak" hours, which offer the lowest rates and are discounted by up to 40% from flat rates. These super off-peak hours are usually from 10 pm to 6 am, seven days a week.
By taking advantage of off-peak and super off-peak hours, you can avoid higher weekday rates when energy resources are in higher demand. For example, you can set your dishwasher, washing machine, or dryer to run during off-peak hours, or wait until off-peak hours to charge your electric car.
Additionally, some utilities offer special programs if you charge an electric vehicle (EV) during off-peak hours or reduce your energy consumption on certain days of the year. Check with your utility company to see what programs are available and how they can be incorporated into your existing rate plan.

Time-of-use plans
The goal of time-of-use plans is to incentivize customers to consume energy when it is cheaper to generate and discourage consumption when it is more expensive. This helps to even out demand on the electrical grid, reducing strain on the infrastructure. By understanding the time-of-use rates, customers can adjust their usage habits to take advantage of lower-priced periods and reduce their overall electricity costs. For example, running a washing machine at 9 pm instead of 6 pm can save almost $12 annually.
Some time-of-use plans include a demand charge, which encourages businesses to spread their electricity use throughout the day. This demand charge is calculated using the highest 15-minute interval of usage in a billing month, and it can help to lower overall electricity costs when reduced.
Overall, time-of-use plans offer customers the potential to save money on their electricity bills by providing cost transparency and encouraging energy usage during lower-demand periods.

Energy demand
Demand for electricity varies throughout the day and is influenced by various factors, including the time of year, day of the week, and even the specific time of day. Peak hours, also known as on-peak hours, occur when energy usage is at its highest. This typically happens when most people are at home, such as in the early morning and late at night, and especially during the summer weekdays. For example, in California, peak hours are from 4 pm to 9 pm every day, with the highest rates during summer weekdays.
In contrast, off-peak hours refer to periods when electricity demand and prices are lower. These typically occur during weekends and holidays when fewer people are at work or school, and energy usage is reduced. Off-peak hours can vary between energy providers but generally range from 10 pm to 5 am.
By understanding energy demand patterns, consumers can take advantage of lower rates during off-peak hours. This may involve adjusting daily routines and scheduling energy-intensive tasks, such as laundry or running the dishwasher, outside of peak hours. Additionally, consumers can consider investing in energy-efficient solutions, such as solar panels or batteries, to further reduce their energy costs and contribute to a more sustainable energy future.
Some energy providers offer time-of-use (TOU) plans, which directly tie the rates to the time of day and season. These plans allow consumers to take advantage of lower rates during off-peak hours and super off-peak periods, helping them reduce their overall energy costs. However, it is important to carefully review the terms of TOU plans, as they may also include demand charges based on the highest amount of energy used, regardless of the time of use.

Saving money
The time of day can significantly affect electric costs. By understanding the concept of peak and off-peak hours, you can make informed decisions about your energy usage and reduce your electricity bills. Here are some essential insights and strategies to help you save money on your electric costs:
Understanding Peak and Off-Peak Hours:
Peak hours, also known as on-peak hours, are the periods of the day when electricity demand is at its highest. During these times, the cost of electricity per kilowatt-hour is at its most expensive. Typically, peak hours occur when most people are at home, using various electrical appliances, such as during the early morning and evening. Summer weekdays tend to have higher rates, especially during the hours of 4 pm to 9 pm or 5 pm to 8 pm.
On the other hand, off-peak hours are when electricity prices are at their lowest. This is because fewer people are using electricity, resulting in reduced demand. Generally, weekends and holidays are considered off-peak hours, along with the late-night hours, typically from 10 pm to 5 am.
Strategies to Save Money:
- Shift Energy Usage to Off-Peak Hours: By adjusting your energy-intensive tasks to off-peak hours, you can take advantage of lower electricity rates. This may include running your dishwasher, washing machine, or dryer during these periods.
- Utilize Scheduling Functions: Many modern appliances offer scheduling functions. Use these features to set your appliances to run during off-peak hours, even when you're not at home.
- Manage Your Thermostat: Keep your air conditioner set to 78 degrees Fahrenheit or above, especially during peak hours, to reduce costs. Additionally, consider pre-cooling your home before 3 pm and using a programmable thermostat to manage temperatures more efficiently.
- Charge Electric Vehicles at Night: If you own an electric car, plan to charge it during off-peak hours, preferably overnight, to benefit from lower rates.
- Unplug Unused Appliances: Be mindful of appliances that are not in use. Unplug them or utilize "sleep" mode to minimize unnecessary electricity usage, especially during peak hours.
- Consider Solar Power: If you have the option, incorporate solar power into your energy plan. This can include installing solar panels or using a solar battery to reduce your reliance on the grid during peak hours.
- Review Your Energy Plan: Different utility companies offer various rate plans, such as time-of-use (TOU) plans or tiered rate plans. Review the options available in your area and choose the one that best suits your usage patterns to maximize savings.
