What are time-of-use (TOU) rates?

Time-of-Use (TOU) rates can be a game-changer for homeowners, especially those considering solar panel installation. These rates involve varying electricity prices depending on the time of day, encouraging energy use when demand is lower and supply is plentiful.

In this blog, we’ll explore how TOU rates work, their benefits, and how to maximize savings by adjusting your energy usage according to these rates.

Understanding TOU Rates

Time-of-Use (TOU) rates are a dynamic pricing scheme where electricity costs vary between peak and off-peak hours. Unlike flat-rate billing, which offers no incentive for when you use energy, TOU rates encourage shifting electricity use to off-peak times, typically late at night and early in the morning, to benefit from lower prices. 

Peak hours often occur from 4 PM to 9 PM on weekdays when demand is highest, and rates are higher. In contrast, during off-peak times, such as from midnight to 6 AM, prices drop, offering savings and reducing the strain on the power grid. This pricing model not only helps manage energy consumption more efficiently but also aligns with environmental benefits by balancing the load on the grid during high-demand periods like summer.

Benefits of TOU Rates for Homeowners

By shifting energy-intensive activities to off-peak times, homeowners can reduce their electricity bills significantly. For example, a homeowner who runs their dishwasher, laundry machines, and other appliances during off-peak hours can potentially cut their energy bills by up to 30%. Additionally, using less energy during peak times reduces the need for utilities to rely on less efficient power plants, thereby decreasing overall carbon emissions and promoting environmental sustainability.

How to Maximize Savings with TOU Rates

Homeowners can maximize their savings under TOU rates by running high-energy appliances like dishwashers and laundry machines overnight or early in the morning. Charging electric vehicles during off-peak hours also contributes to lower energy costs. Home automation systems can be programmed to operate appliances during off-peak hours, and smart thermostats can adjust heating and cooling patterns to align with cheaper energy rates. 

Furthermore, solar panels generate electricity during peak sun hours, which often coincide with peak rate times, allowing homeowners to use solar energy when it’s most financially advantageous. Solar batteries enhance these benefits by storing energy produced during the day for use during expensive peak rate periods.

Common Misconceptions About TOU Rates

Some believe TOU rates mean higher bills. However, with strategic management of energy usage, homeowners can experience significant savings. It is crucial to understand your personal energy usage patterns to maximize the benefits of TOU rates without increasing your overall energy costs.

Getting Started with TOU Rates

TOU rates are not available in all areas, so it’s important to check with your local utility provider to see if they offer TOU rate plans. Several apps can help you track and manage your energy usage according to TOU rates, helping you adjust your habits to save on utility bills. These tools and a bit of planning can make TOU rates a very beneficial choice for energy management in your home.
