How to save money with time-of-use (TOU) plans

Time-of-use (TOU) plans are becoming increasingly popular for residential customers, and for good reason. With a TOU plan, you can save money by shifting your energy usage to partial-peak and off-peak hours, which have lower rates. Here are some detailed tips on how to save money with a TOU plan:

Understand your TOU plan's schedule

TOU plans are based on a schedule of peak, partial-peak, off-peak, and super off-peak hours, which are determined by your utility company. Understand when the rates are lowest so that you can schedule your energy usage accordingly. Some plans may also vary depending on the season, with summer rates being higher than winter rates due to the increased use of air conditioning.

Shift your energy usage to off-peak hours

This is the key to saving money on a TOU plan. Schedule energy-intensive tasks such as laundry, running the dishwasher, and charging your electric vehicle during off-peak hours, usually at night or on weekends. You can also pre-cool your home before peak hours and turn up the temperature when you leave to reduce energy usage during peak times.

Adjust your habits

Small adjustments to your daily habits can help you save money on a TOU plan. For example, you can set your dishwasher to run with a delay feature so that it operates during off-peak hours. You can also use the cold or cool water setting for washing clothes, as heating water accounts for most of the energy used in each wash.

Spread out your electricity use

Some TOU plans include a demand charge, which encourages you to spread out your electricity use throughout the day. This charge is based on the highest amount of energy used during a 15-minute interval in a billing month. By lowering your highest usage interval, you can reduce your overall electricity costs.

Explore energy-saving options

Consider investing in energy-efficient appliances and home upgrades, which can help you save money in the long run. Take advantage of financial incentives and rebates offered by your utility company to make energy efficiency upgrades more affordable. You can also sign up for text alerts to receive reminders about your plan's schedule and tips for saving energy.

By following these strategies and adjusting your energy usage habits, you can take advantage of the lower rates offered by TOU plans and save money on your electricity bills.

Off-peak and peak hours

Time-of-Use (TOU) plans are becoming increasingly popular for utilities to offer to their residential customers. These plans allow you to pay different prices for electricity based on the time of day and year. On and off-peak electricity hours are when utilities shift electricity prices based on demand.

Electricity peak hours are times when businesses and residential customers use the most electricity. Peak hours vary depending on the season and region. For example, on the East Coast, peak hours during the summer are often from 2 p.m. to around 6 p.m., while in the winter, they change to the early morning. In the Pacific time zone, peak hours during the summer are 5 p.m. to 9 p.m., and in the winter, they are 6 a.m. to 10 a.m. and 6 p.m. to 10 p.m.

Off-peak hours are periods when companies and residences use less electricity, typically at night and on weekends and holidays. During off-peak hours, electricity rates are lowest. For example, in the Pacific time zone, off-peak hours during the summer are 9 a.m. to 5 p.m., and in the winter, they are 10 a.m. to 5 p.m. and 8 p.m. to 5 a.m.

By adjusting your habits and using more energy during off-peak hours, you can take advantage of lower rates and save money on your electricity bill. For example, you can shift large appliance use, such as laundry and running the dishwasher, to off-peak hours. Additionally, you can use energy-efficient practices, such as using cold or cool water settings for washing and unplugging unused devices, to further reduce your energy consumption and costs.

Some utilities also offer tiered rate plans, where customers are charged a higher rate if they regularly use extremely high amounts of energy. Demand charges may also be included in TOU plans, where the highest amount of energy used during a 15-minute interval in a billing month is used to calculate a demand charge, which can increase costs. Therefore, it is important to consider your usage patterns and budget when choosing an electricity plan.

Demand charges

In some cases, demand charges can lead to more expensive bills, especially for those with solar panels. This is because demand charges are based on the peak power requirement (kW) rather than the total energy consumed (kWh). However, with the right resources and knowledge, it is possible to reduce monthly bills on a demand charge rate. Demand charges can encourage businesses to spread their electricity use throughout the day, making the supply of electricity more reliable.

How to adjust habits to benefit from lower rates

Time-of-Use (TOU) plans are becoming increasingly popular for residential customers. These plans offer varying rates based on the time of day and year, allowing customers to take advantage of lower prices during off-peak hours. By adjusting your habits and shifting energy-intensive tasks to these off-peak periods, you can benefit from reduced electricity rates and lower your energy bills. Here are some ways you can adjust your habits to maximize the benefits of TOU plans:

Laundry and Dishwashing

Laundry and running the dishwasher are energy-intensive tasks. Try to schedule these activities during off-peak hours, which are typically all day on Saturdays and Sundays. You can also do laundry during the week but after peak hours, such as after 9 pm. Using the cold or cool water setting for washing clothes can also help reduce energy consumption. Additionally, make sure to fill your dryer without overfilling it, as small and large loads use similar amounts of energy.

Heating and Cooling

Heating and cooling systems can consume a significant amount of energy. In the summer, try to avoid using air conditioning during peak hours, which are typically in the afternoon and early evening. Instead, use natural ventilation or fans during these times. In the winter, you can take advantage of lower rates in the early morning or late at night to heat your home.

Electric Vehicle Charging

If you own an electric vehicle, consider charging it during off-peak hours. Many TOU plans offer super off-peak rates during these periods, allowing you to save on charging costs.

Delay Features and Timers

Many appliances, such as dishwashers, have delay features or timers. Utilize these functions to schedule the appliances to run during off-peak hours automatically. This way, you can still enjoy the convenience of using your appliances whenever you need to without incurring higher energy costs.

Renewable Energy Sources

Consider investing in renewable energy sources, such as solar panels. TOU plans often make adding solar panels to your home more financially viable. By generating your own electricity, you can reduce your reliance on the grid during peak hours and take advantage of net metering programs.

By following these adjusted habits and being mindful of your energy usage, you can take control of your energy bills and make significant savings while also contributing to a more sustainable energy future.

How to choose the best rate plan

Time-of-Use (TOU) rate plans are becoming an increasingly popular option for residential customers. TOU plans can help you manage your energy costs by charging you different rates based on the time of day and year that you are using energy. Typically, electricity is cheaper at night, during weekends, and on holidays.

If you are considering switching to a TOU plan, you should first ask yourself the following questions:

  • What electricity rate plans does your electricity provider offer?
  • How much energy do you use, and when do you use it?
  • How flexible is your schedule, and are you able to shift your energy use to off-peak times?

If you are able to manage your energy habits, a TOU plan may be a good fit for your home. By taking advantage of lower rates during off-peak and super off-peak periods, you can avoid higher weekday rates when energy resources are in demand. Bills may be higher during the summer, but overall annual energy costs can be lower.

Some TOU plans include a demand charge, which is based on the highest amount of energy used during a billing month. This charge encourages users to spread their electricity use throughout the day, which can help to lower your regular electricity usage charges by up to 30%.

You can also use tools like the Bill Analyzer Tool or the DTE Insight App to help you understand your energy usage and determine which rate plan is best for you.
