With the ever-rising cost of electricity, it is important to know when the cheapest times of the day are to use electricity. The cheapest times to use electricity are during off-peak hours, when demand for power is lower, and utilities reduce rates to encourage usage. Off-peak hours typically fall late at night or early in the morning, such as 9 pm to 7 am, but they can vary by region and season. These hours often coincide with periods of reduced activity in homes and businesses, making it an ideal time to run appliances like washing machines or charge electric vehicles at a lower cost.

What You'll Learn

Off-peak hours are typically late at night or early in the morning
Off-peak hours are periods when energy demand is significantly lower, allowing utility companies to offer discounted rates. Power plants can operate more efficiently, and the electricity is cheaper, while the grid experiences less congestion during these periods. This benefits both consumers, who enjoy lower bills, and utilities, which save on operating costs.
Off-peak hours typically fall late at night or early in the morning, such as 9 pm to 7 am, but they can vary by region and season. These hours often coincide with periods of reduced activity in homes and businesses, making it an ideal time to run appliances like washing machines or charge electric vehicles at a lower cost. For example, a customer mentions that they "shift[ed] my laundry [...] to the morning on the weekend and set my dishwasher [...] to run after 9 p.m."
The exact timing depends primarily on your location and the off-peak periods utilities operate. Many rate plans will depend not only on the hours you’re using electricity but also on the season. Summer rates are often higher than winter rates because of energy-intensive air conditioning systems running during hot days.
To save money on your electric bill, be aware of when your electricity rates are cheapest and schedule your energy usage accordingly. Your electric bill is based on a charge per kilowatt-hour (kWh), so you’re billed for the actual electricity pulled from the grid. Under time-of-use rate plans, your utility charges you more for electricity usage during afternoon “peak” hours when electricity demand is higher.

Time-of-use tariffs can help you save money
Many appliances nowadays come with a timer feature, allowing you to delay their start until the off-peak period begins. Some products even have an app that lets you set a start time from anywhere. You can also use smart power strips for devices like your TV, games console, and lamps.
Time-of-use rate plans are based on how much energy you use and when you use it. These plans support clean energy policies and help create a more reliable energy grid by encouraging energy usage during off-peak hours. They are widely adopted by electricity providers and can help you save money on your electric bill if you schedule your energy usage accordingly.
To determine if a time-of-use tariff is right for you, compare the current rate you're paying for electricity to the rates under a time-of-use plan. Off-peak pricing should be significantly cheaper for you to benefit from switching plans. Additionally, be sure to check with your utility provider about their specific off-peak and on-peak hours, as these can vary.
By choosing a time-of-use tariff and adjusting your energy usage habits, you can optimize your electricity costs and make substantial savings on your energy bills.

Peak hours are when electricity demand is highest
During peak hours, electricity rates are higher due to increased demand. This is when most households are active, with cooking, heating, and cooling systems running. Therefore, it is beneficial to shift energy-intensive activities to off-peak hours to save money. Many appliances now come with timers or apps that allow users to delay their operation until off-peak periods.
Time-of-use rate plans or tariffs offer lower rates during off-peak hours and super off-peak periods, helping consumers avoid higher rates during peak hours. These plans can result in significant savings on electricity bills, but they require careful planning and adjustments to energy usage habits. Some plans, like Agile Octopus, provide dynamic pricing that changes every 30 minutes, allowing users to adapt their energy consumption accordingly.
It is important to note that the success of a time-of-use tariff depends on how it aligns with your energy usage patterns. Before switching to such a plan, it is essential to understand your energy habits and compare the rates with your current plan. Additionally, consider other cost-saving measures, such as investing in solar panels or energy storage solutions, to maximize your energy efficiency and reduce overall electricity costs.

Demand for electricity varies across the year
On the East Coast, it's hottest after 2 pm, so the peak hours for this region are often from 2 pm to 6 pm. In contrast, during the winter, peak hours change to the early morning as homeowners and businesses turn up the heat to keep their living and work spaces comfortable.
Time-of-use rate plans are based on how much energy you use and when you use it. These plans support California's clean energy policies by encouraging energy usage when solar power is contributing to the power grid. Off-peak electricity hours are periods when energy demand is significantly lower, typically falling late at night or early in the morning, allowing utility companies to offer discounted rates. Power plants can operate more efficiently, and the electricity is cheaper, and the grid experiences less congestion during these periods. This benefits both consumers, who enjoy lower bills, and utilities, which save on operating costs.
To save money on your electric bill, be aware of when your electricity rates are cheapest and schedule your energy usage accordingly. For example, you can shift energy-intensive activities like laundry or dishwashing to save money.

You can save money by adjusting your energy habits
Energy is usually cheapest at night, specifically between 9 pm and 7 am, but the exact timing depends on your location and the off-peak periods utilities operate. During off-peak hours, demand for power is lower, and utilities reduce rates to encourage usage.
Another way to save money is to be mindful of your energy consumption and make some energy-efficient upgrades in your home. Here are some ways to do that:
- Adjust your thermostat based on the season and whether you're home or away.
- Use ceiling fans properly—in the summer, set them to spin counter-clockwise to pull hot air up, and in the winter, reverse the setting to blow hot air down.
- When purchasing appliances, look for the Energy Star label, which guarantees that these appliances will consume less energy than standard models.
- Turn off electronics and unplug them when not in use to eliminate "phantom energy," which can account for 5-10% of residential energy use.
- Install smart power strips that shut off the power to electronics when they're not in use.
- Seal and insulate your house to retain heat during the winter and keep heat out during the summer.
- Reduce your water heating expenses by insulating your water heater and the first six feet of hot and cold water pipes.
- Install low-flow fixtures in your shower, faucets, and toilets to conserve water.
- Turn down the brightness setting on your TV, and switch on the ambient light sensor to reduce power consumption.

Frequently asked questions
The cheap times for electricity are during off-peak hours, when demand for power is lower, and utilities reduce rates to encourage usage. Off-peak hours typically fall late at night or early in the morning, such as 9 pm to 7 am, but they can vary by region and season.
If you are on a standard tariff, you will be charged the same rate for your electricity usage, no matter the time of day. If you are on a time-of-use tariff, your contract will have a peak price and an off-peak price, with the latter being cheaper.
You can switch to a time-of-use tariff by comparing off-peak tariffs on an energy comparison website or by asking your current provider if they offer suitable off-peak tariffs.
Aside from switching to a time-of-use tariff, you can save money on your electricity bill by investing in solar panels to generate your own power or by simply being more aware of your energy consumption by turning off plug sockets and using energy-saving lightbulbs.
