Are you considering TOU rates for your Texas household? Before you start the journey of applying for this innovative pricing metric, it is essential to grasp the fundamentals of time of use (TOU) rates and how they operate. We will provide you with comprehensive insights into time of use rates, empowering you to make informed decisions for your energy consumption needs.

Understanding the Concept of TOU Rates

TOU rate refers to the pricing structure where electricity costs vary based on the time of day. They aim to incentivize consumers to shift their energy consumption from high-cost peak hours to lower-cost periods. In other words, this type of rate system allows consumers to optimize high electricity usage by switching it during periods when the electricity is cheaper.

Generally, time of use rates vary kWh rates based on different times of day, days of the week, and even months of the year. That is why Rhythm Energy offers multiple time of use plans based on your needs. Each of those comes with transparent TOU rates, meaning that you'll be able to choose the one that fits your needs. This way, you'll save a lot of money on electrical bills because you'll always know when the electricity is cheap and when is the right time to turn on energy-intensive devices, such as electric vehicles (EVs). Moreover, this change in energy usage patterns also promotes a greener and more sustainable approach to electricity consumption.

How TOU works:

Many utility companies employ this type of system, and here’s how it works:


On-peak vs. off-peak hours

TOU creates pricing for electricity plans based on on-peak and off-peak periods. When it comes to on-peak hours in Texas, they occur during weekday afternoons and evenings, when electricity demand is high because of increased household activity. Off-peak hours, on the other hand, fall during late nights, early mornings, and weekends when electricity demand is lower.

The exact timing of peak and off-peak hours also may vary, depending on the provider. One of the things that Rhythm Energy's plans stand out from other similar providers is the versatility in points, such as:

When to reduce your usage

  • On-peak: High-demand time when electricity costs more. Shift usage outside this window based on your plan's structure (morning, evening, or both) to save money.

  • Seasonal on-peak: Seasonally high-demand time when electricity costs more, like winter mornings when people are heating their homes. Limit heavy appliance usage and reduce AC/heat (especially electric) during this period.

When you use more power

  • Off-peak: Low-demand time when electricity costs less. You’re encouraged to use electricity-heavy items during this period for cost savings, environmental benefits, and grid efficiency.

  • Ultra off-peak: Cheapest-priced period with lowest electricity demand, usually overnight. Utilize this time to charge your EV, use AC, or heat your space.

When is the most expensive to use electricity? In Texas, peak hours are designated as the timeframe from 1 p.m. to 7 p.m., Monday through Friday. Also, the electricity expenses change depending on the time of the year. Because of high temperatures during the summer months (from June to September), TOU rates are higher. What is the cheapest time of the day to use electricity?

While it might depend on your energy provider and its time TOU rates, the cheapest time of the day to use electricity is during early mornings or late evenings. With Rhythm Energy's renewable energy plans, you can easily check the most cost-effective periods. Rhythm Energy provides a reliable source to track and determine the specific times when electricity costs are lower. With this information, you can better plan your energy consumption and maximize savings on your electricity bills. Is Time of Use Rates Worth It? To answer shortly, yes. Time of use Texas rates are worth for several reasons:

  • Transparency: Time of use electricity rates allow you to check how electricity costs fluctuate during the day, so you can decide when it's a good time to complete your chores.

  • Control over savings: By shifting energy consumption to off-peak hours, you will take advantage of lower rates, reducing monthly bills.

  • Environmental contribution: Shifting your energy usage away from peak periods, helps create a more sustainable and eco-friendly energy consumption pattern. It's a simple way for you to make a positive impact on the environment.

A time of use rate bill vs. standard bill

There's a difference between a TOU rate bill and a standard bill. In order to calculate a standard monthly bill, you'll need to multiply the rate you pay for electricity by the portion of electricity you consumed during the month. Under the TOU billing structure, calculating the costs means multiplying the electricity used during specific hours of the day by the rates assigned to those hours. This way, customers are able to check their electricity usage during peak and off-peak periods and adjust their energy spending habits.

How to make the most of TOU in Texas


There are many things that you can do to make the most of your time of use electricity. First of all, you should familiarize yourself with the specific peak and off-peak hours defined by your time of use rate plan in Texas. Then, you should organize your daily chores that require significant energy, such as running the dishwasher or doing laundry, during off-peak hours. Don't forget that Rhythm Energy offers various price points during the day with lower TOU rates.

The next thing you can do is to check what appliances use the most energy. For example, air conditioning (AC) units are one of the most energy-intensive appliances, especially during hot summer days. The constant need to cool your home can lead to significant energy consumption, so you should consider alternative ways of cooling your home, like fans or natural ventilation.

While you cannot do anything about some energy-intensive devices such as refrigerators and freezers, others you might use smartly and only when TOU rates are low. For example, you can use clothes dryers only when TOU energy rates are off-peak.

Finally, you should keep track of your energy usage. By knowing your energy usage patterns, you can identify areas where you can further optimize your energy consumption. By implementing these strategies, you can maximize the benefits of time of use rates, save money on your electricity bills, and also contribute to efficient and environmentally conscious energy choices.
