The time of day has a significant impact on electricity rates, with many power companies offering lower rates during off-peak hours, typically at night, on weekends, and during holiday periods. These off-peak hours usually occur after most people have gone to bed and before they wake up, although the exact timing depends on your location and the utility provider. By taking advantage of these lower rates, consumers can reduce their energy costs and manage their energy habits, such as scheduling energy-intensive tasks like laundry or charging electric vehicles during these cheaper periods. Additionally, utilizing renewable energy sources, such as solar panels, can further lower electricity bills and provide incentives for shifting energy usage to off-peak times. Understanding the dynamics of peak and off-peak rates is essential for making informed choices when selecting an energy plan that best suits one's needs and usage patterns.

What You'll Learn
Off-peak hours
In general, off-peak hours for electricity rates occur during the night, after most people have gone to bed and before they wake up. This is because energy demand is typically lower during these quiet periods. However, the exact timing of off-peak hours can depend on your location and the energy provider's off-peak periods. For example, in the UK, some suppliers consider the hours between 4 pm and 7 pm as off-peak, coinciding with when people return home from work or school.
Time-of-Use (TOU) plans or tariffs are designed to encourage consumers to shift their electricity consumption to off-peak hours, helping to reduce the strain on power plants and the grid. With TOU plans, you pay different prices for electricity based on the time of day and year. During "peak" hours when demand is high, you pay a higher price, while off-peak hours offer lower rates.
By taking advantage of off-peak hours, you can lower your electricity costs. This may involve scheduling energy-intensive tasks, such as laundry or charging appliances, during the cheaper off-peak rates. Additionally, utilizing energy-efficient appliances, such as ceiling fans, air conditioners, and furnaces, can further help reduce your energy consumption and costs.
It's important to note that the definition of off-peak hours can vary among energy providers, and it's recommended to check your specific tariff details to identify the exact off-peak periods. Additionally, comparing the current rate you're paying with the rates under a TOU plan is essential to determine if switching to a time-based plan will result in significant savings.

Time-of-use plans
The exact timing of peak and off-peak hours depends on your location and the specific weather conditions. Generally, energy is cheapest at night, regardless of the region or time of year. For example, on the East Coast of the United States, peak hours often occur in the afternoon, from around 2 pm to 6 pm, due to the use of air conditioning during hot summer days. In contrast, during the winter, peak hours shift to the early morning as homeowners and businesses turn up the heat.
It's important to note that the effectiveness of a time-of-use plan depends on your current rate plan and energy usage habits. Before switching to a time-of-use plan, compare the rates and consider whether you can adjust your energy usage to take advantage of off-peak hours. Additionally, keep in mind that some plans may have limits, and exceeding a specific usage threshold may result in excess charges.

Cheapest times to use electricity
The cheapest times to use electricity depend on the region, the season, and the time of day.
In general, electricity is cheaper at night, during off-peak hours, when demand is lower. This is usually between midnight and 8 am. However, the specific off-peak hours can vary between suppliers, regions, and seasons. For example, in the summer, off-peak hours may start later in the evening, while in the winter, they may start earlier.
Some time-of-use (TOU) tariffs offer cheaper rates during specific times of the day, such as between 9 pm and 4 pm the next day in the summer. These plans can help you manage your energy costs by taking advantage of lower rates during off-peak and super off-peak periods. However, TOU plans can be complicated and confusing, and they may not be the best option if you cannot adjust your energy usage to off-peak hours.
Additionally, some suppliers offer reduced rates during weekends and holiday periods, when demand is also typically lower. Dynamic tariffs track the wholesale price of electricity and offer varying prices per kWh, which can result in negative pricing during periods of high generation and low consumption.
To find the cheapest times to use electricity in your specific region, it is recommended to compare the current rate you are paying with the rates offered by different suppliers and consider factors such as the time of year and your energy usage habits.

Reducing energy costs
Energy costs can be reduced by switching to a Time-of-Use plan, which allows you to take advantage of lower rates during off-peak hours. Typically, electricity prices are lower early in the day, overnight, and on weekends. However, it's important to note that summer rates tend to be higher than winter rates due to the increased use of air conditioning.
To effectively utilise a Time-of-Use plan, you can schedule energy-intensive tasks for off-peak hours. For example, running your dishwasher or doing laundry during the late evening can help you save money. Additionally, consider investing in a backup battery to charge during off-peak hours and discharge during peak hours.
Another way to reduce energy costs is to improve energy efficiency in your home. This can be achieved by purchasing energy-efficient appliances, lighting, and heating/cooling systems. You can also reduce energy consumption by turning down your thermostat, especially when you're not at home or during sleep.
Some other tips to reduce energy costs include:
- Turn down the temperature of your hot water tank to 120 degrees Fahrenheit.
- Use a microwave instead of a conventional oven.
- Wash and dry full loads of laundry and use cold water settings.
- Reduce your shower time and limit baths.
- Only boil the amount of water you need in the kettle.
- Use LED lights instead of traditional bulbs.
- Run your washing machine on a 30-degree cycle.
- Avoid using the tumble dryer and opt for drying clothes inside or outside racks when possible.

Energy schedule and smart thermostats
Energy rates vary depending on the time of day, day of the week, season, and region. Typically, energy is cheaper at night, on weekends, and in the winter. You can save money on your energy bills by scheduling energy-intensive tasks for off-peak hours. For example, you could run your dishwasher during off-peak hours instead of peak hours.
Time-of-Use (TOU) plans allow you to take advantage of lower rates during off-peak and super off-peak periods, helping you avoid higher rates during peak hours when energy demand is high. Some TOU plans offer lower rates during the day when solar power contributes to the power grid.
Smart thermostats can also help you save energy and money. ENERGY STAR-certified smart thermostats have been independently certified to deliver energy savings. They can learn your temperature preferences and establish a schedule that automatically adjusts to energy-saving temperatures when you are asleep or away. You can also control your home's temperature remotely through your smartphone, allowing you to adjust the temperature when you're on your way home so that you arrive at a comfortable home. Additionally, smart thermostats provide equipment use and temperature data that you can track and manage.
Programmable thermostats can help you save energy by allowing you to adjust the times you turn on the heating or air conditioning according to a preset schedule. You can store and repeat multiple daily settings (six or more temperature settings per day), which you can manually override without affecting the rest of the daily or weekly program. For example, you can set the thermostat to around 68°F to 70°F while you're awake and set it lower while you're asleep or away from home in the winter. In the summer, you can keep your house warmer when you're away and set the thermostat to a comfortable temperature when you're at home and need cooling.
