Time-of-Use Contracts vs. Flat-Rate Plans: What’s the Difference?

May 20th, 2025 By Casey Thornton | Fact Checked By EO Test Reviewer

When it comes to electricity, there are two main types of contracts: time-of-use and flat-rate. Both of these contracts have their pros and cons, which is why it can be difficult to decide which one is right for you. In this blog post, we will discuss the differences between time-of-use contracts and flat-rate plans. We will also take a look at how each of these contracts affects your energy bill.

Time-of-Use Contracts

Time-of-use contracts are based on the time of day that you use electricity. There are three different time periods: peak, off-peak, and shoulder. Peak hours are when electricity is most expensive, off-peak hours are when it is cheapest, and shoulder hours fall in between these two prices. With a time-of-use contract, you are charged different rates for each of these three periods.

A time-of-use contract can be a great deal for some people, but it may not be worth it for everyone. It all depends on your lifestyle and how you use electricity. If you use a lot of electricity during peak hours, then a time-of-use contract will save you a lot of money. However, if you use most of your electricity during off-peak hours, then a time-of-use contract may not be the best option for you.

Flat-Rate Plans

Flat-rate plans charge you the same price for electricity no matter what time of day you use it. This can be a good option if you don’t want to worry about switching your appliances off during peak hours. However, flat-rate plans usually cost more than time-of-use contracts.

Whether or not a flat-rate plan is worth it depends on your lifestyle and how you use electricity. If you use a lot of electricity during peak hours, then a time-of-use contract will save you a lot of money. However, if you use most of your electricity during off-peak hours, then a time-of-use contract may not be the best option for you.

How Does This Affect Your Energy Bill?

So, how does this affect your energy bill? Well, it really depends on your electricity provider and the plan that you choose. Some providers will charge you a higher rate for peak hours, while others will charge more for off-peak hours. It’s important to read the fine print of any contract before signing up, so you know exactly what you’re getting into.

In general, time-of-use contracts are cheaper than flat-rate plans. However, if you don’t use very much electricity during off-peak hours, then a time-of-use contract may not be the best option for you. Flat-rate plans are ideal for people who use a lot of electricity during peak hours.

If you’re still not sure which type of contract is right for you, talk to your electricity provider. They can help you decide which plan will save you the most money. You always have the Power to Choose the best contract for you!
