The cost of electricity varies depending on the time of day and year. Many power companies charge higher rates during the afternoon and early evening, when demand is highest as people return home from work and school and use more energy. This is known as peak demand. The cheapest electricity is usually found during off-peak hours when demand is lower, often at night. Some utility companies also offer special rates for customers who use renewable energy sources or drive electric vehicles. By adjusting your energy habits and taking advantage of off-peak hours, you can make significant savings on your energy bills.

What You'll Learn
Cheapest at night
Energy is usually cheapest at night, regardless of the region or time of year. This is because, despite lower demand, large power plants and wind turbines continue to produce electricity at night. In fact, according to the Lawrence Livermore National Laboratory, wind turbines produce more power at night.
During the day, especially in the afternoon and early evening, electricity is in high demand as people return from work and school, run their appliances, and adjust their thermostats. This is when electricity is most expensive.
However, the exact timing of off-peak periods depends on your location and the utilities available to you. For example, in California, summer weekdays from 4 pm to 9 pm are considered on-peak, while all other hours are off-peak. In contrast, winter rates are identical on weekdays and weekends, with 8 am to 4 pm considered Super Off-Peak, 4 pm to 9 pm as Mid-Peak, and 9 pm to 8 am as Off-Peak.
You can take advantage of lower rates during off-peak hours by adjusting your energy habits. This may include shifting large appliance use, such as laundry and dishwashing, to off-peak hours. Additionally, consider using smart appliances and solar batteries to help manage your energy usage and costs.
By choosing a time-of-use rate plan, you can further optimize your energy costs. These plans offer varying rates based on the time of day and season, allowing you to take advantage of lower rates during off-peak periods. Some plans also provide special rates for customers with electric vehicles or those who reduce energy consumption on specific days.
In summary, by understanding the dynamics of energy rates and adopting strategic habits, you can significantly reduce your energy costs, especially by utilizing off-peak hours at night when electricity is typically cheapest.

Location and season-dependent
The cheapest time of day for electricity is dependent on a variety of factors, including your location and the season. Energy is usually cheapest at night, regardless of region or time of year, due to lower demand. However, the exact timing of off-peak hours can vary depending on your location and the time of year.
For example, in California, summer weekdays from 4 pm to 9 pm are considered on-peak or mid-peak hours, with higher electricity rates, while weekends during the same time period are classified as mid-peak or off-peak, resulting in lower rates. In contrast, winter rates are identical on weekdays and weekends, with 8 am to 4 pm being super off-peak, 4 pm to 9 pm as mid-peak, and 9 pm to 8 am as off-peak.
Location also plays a significant role in determining the cheapest time of day for electricity. For instance, in Texas, where the energy market is deregulated, residential customers can choose their electricity supplier and benefit from various rate plans, such as "free nights" or "free weekends," which are offset by higher energy costs during weekdays.
Additionally, the type of rate plan you have can impact the cheapest time of day for electricity. Tiered rate plans may charge higher rates if you regularly consume extremely high amounts of energy. Time-of-use (TOU) rate plans offer different prices based on the time of day and year, with higher rates during afternoon "peak" hours when demand is higher, and lower rates during "off-peak" hours when demand is lower.
By adjusting your energy habits and utilizing smart appliances, solar panels, or energy storage solutions, you can take advantage of lower rates during off-peak hours and reduce your overall energy costs. Some energy providers offer tools like a Bill Analyzer Tool to help you understand your energy usage and make more informed choices.

Time-of-use rate plans
For example, in California, the peak hours are from 4 pm to 9 pm on summer weekdays, while in the winter, the peak hours shift to the early morning. In contrast, the off-peak hours in Michigan are from 9 pm to 3 pm on weekdays and all weekend long.
You can take advantage of these lower rates by adjusting your habits and using appliances like the dishwasher, laundry machines, and air conditioning during off-peak hours. Some utility companies also offer special rates for customers with electric vehicles or those who reduce energy consumption on specific days.
Additionally, you can use tools like smart thermostats, smart appliances, and solar panels to help manage your energy usage and costs. By analyzing your energy bill and comparing rate plans, you can identify areas where you can make adjustments and choose the most cost-effective plan for your needs.

Tiered rate plans
It is important to note that the specific details of tiered rate plans can vary by provider and location. For instance, DTE Energy offers a plan with moderate savings during off-peak hours, which are best utilized by shifting weekday usage to evenings after 7 pm. On the other hand, PG&E offers a Time-of-Use rate plan with lower prices before 4 pm and after 9 pm on weekdays, encouraging customers to shift their energy usage outside of the peak hours of 4-9 pm.
Additionally, some utility companies may combine tiered rate plans with time-of-use plans, allowing customers to take advantage of both the flexibility of tiered pricing and the lower prices during off-peak hours. By understanding your energy usage patterns and the options available, you can make an informed decision about which rate plan best suits your needs.

Solar rate plans
Under a Time-of-Use (TOU) plan, electricity rates vary based on the time of day and year. On-peak hours, which are typically from 4 pm to 8 pm, have higher rates due to increased energy consumption. Off-peak hours, such as at night, have lower rates as demand is generally lower during these periods. Solar rate plans often work in conjunction with TOU plans, allowing customers with solar panels to benefit from lower rates during the day when solar energy production is at its highest.
In some states, such as California, customers with solar panels are required to switch to a TOU plan. These plans take into account the time of energy usage and net metering, which provides credits for excess energy produced by solar panels that can be exported to the grid. Additionally, some utility companies offer special rates for customers who charge electric vehicles during off-peak hours or reduce energy consumption on specific days.
To maximize savings, it is important to understand your energy usage patterns and align them with the TOU rates. This may involve adjusting your habits, such as running appliances at night or during off-peak hours. Installing smart thermostats and appliances can also help automate energy usage based on the cheapest times of the day.
For residential customers in California, the Solar Billing Plan offers additional benefits. Customers who enroll before January 1, 2028, will have fixed Energy Export Credit (EEC) prices for nine years. Additionally, early adopters are eligible for an additional credit of $0.04 per kWh for residential customers and $0.09 per kWh for low-income customers.
By combining solar rate plans with strategic energy usage and potential utility company incentives, you can significantly reduce your electricity costs and contribute to a more sustainable future.
