Most electricity plans charge you the same rate per kilowatt-hour no matter when you use power. But time-of-use plans, often called TOU plans, take a different approach. They charge different rates depending on the time of day, with higher prices during peak demand hours and lower prices when the grid is less busy. If you can adjust when you use electricity, a TOU plan might save you money.
What Is Time-of-Use Pricing?
Time-of-use pricing divides the day into two or three time blocks: peak, off-peak, and sometimes a shoulder or mid-peak period. Peak hours are typically during the afternoon and early evening when electricity demand is highest. In Texas, peak hours usually fall between 1:00 PM and 7:00 PM on weekdays during summer months. Off-peak hours include late nights, early mornings, and weekends. The rate during off-peak hours can be significantly lower, sometimes half or less of the peak rate.
How TOU Plans Differ from Free Nights and Weekends
TOU plans are sometimes confused with free nights and weekends plans, but they work differently. Free nights and weekends plans typically offer a zero-cost rate during designated hours but charge a higher flat rate during daytime hours to compensate. TOU plans, on the other hand, use a sliding scale where the rate adjusts based on the time period. Neither structure is inherently better. The right choice depends on your usage patterns and how much flexibility you have in when you consume electricity.
Who Benefits Most from TOU Plans?
TOU plans work best for people who can shift a meaningful amount of their electricity usage to off-peak hours. If you work from home and run your air conditioning all afternoon, a TOU plan could actually cost you more than a flat-rate plan. But if you are away during the day and can schedule energy-intensive tasks like laundry, dishwashing, and EV charging for evenings or early mornings, you could see real savings. Households with smart home devices and programmable thermostats are in a particularly good position to take advantage of TOU pricing.
How to Shift Your Usage
The key to saving on a TOU plan is moving discretionary usage out of peak hours. Run your dishwasher and washing machine after 7:00 PM or before noon. Pre-cool your home in the morning before peak rates kick in and let the thermostat drift a degree or two higher during peak hours. Charge electric vehicles overnight. Even small shifts can add up over a billing cycle. Some people find it helpful to set reminders or use smart plugs with scheduling features to automate the process.
TOU Availability in Texas and Ohio
In Texas, several retail electricity providers offer TOU or time-based plans as part of the deregulated market. These plans are available through the competitive retail market, and you can compare them alongside fixed-rate and variable-rate options. In Ohio, TOU options are less common in the competitive market but some utilities offer them as part of their default service. Before enrolling in any TOU plan, look at your electricity facts label or terms of service carefully. Pay attention to how the time blocks are defined, whether the schedule changes seasonally, and what the per-kWh rate is for each period.
Time-of-use plans are not for everyone, but for the right household or business, they offer a practical way to lower your electricity costs without reducing the amount of energy you use. The trade-off is that you need to be intentional about when you consume power.
