Illinois' deregulated energy market
Illinois has a deregulated energy market, meaning that residents and businesses have the freedom to choose their electricity supplier instead of being limited to the local utility company. This was enacted in 1997 through "The Illinois Electric Service Customer Choice and The Rate Relief Law". The law was passed because, at the time, Illinois had some of the highest electricity rates in the United States.
Energy deregulation in Illinois allows for competition among energy companies, which can lead to cheaper electric rates and better terms for consumers. Consumers can choose from a variety of electricity suppliers, with plans that fit their preferences for fixed rates, variable rates, green energy, and more. The exact rate paid depends on the chosen plan and energy usage each month. Fixed-rate plans, for example, provide a set rate per kWh that will not change, offering a predictable monthly bill.
When shopping for a new electricity plan in Illinois, it is important to compare electricity rates from the various suppliers to find the best option. The Price to Compare (PTC) is a useful benchmark price when comparing electricity rates from alternate providers. The PTC is the default energy rate from the local utility, which changes if you switch providers or plans. The average Illinois electricity rate for residential customers is 17.21 cents per kilowatt-hour (kWh), which is 1.1% higher than the national average.
While consumers can switch electricity providers, they must still deal with the utility company for issues such as maintenance and delivery. For instance, in the event of a power outage, consumers would need to contact their utility company to report it and receive updates.

When comparing electricity rates, it is important to understand the different types of plans available. The exact rate you pay will depend on your chosen plan and how much energy you use each month. The most common options are fixed-rate plans, where the price per kilowatt-hour (kWh) remains the same throughout the contract term, and variable-rate plans, where rates can fluctuate based on market conditions. There are also time-of-use plans that offer lower rates during off-peak hours and green energy plans that source electricity from renewable resources.
The "Price to Compare" (PTC) is a key metric that helps consumers evaluate whether switching electricity providers will save them money. This is the default energy rate from your local utility company, which you can use as a benchmark when comparing rates from alternate providers. The PTC will be listed on your bill if your utility supplies your electricity. The average Illinois electricity rate for residential customers is 17.21 cents per kWh, while the average Illinois electricity rate for commercial customers is 11.54 cents per kWh. However, these rates may vary depending on your location and provider, so it is important to compare rates from different suppliers to find the best option for you.
There are several websites that allow you to compare electricity rates in Illinois, such as Choose Energy, EnergyBot, ElectricityRates.com, and SaveOnEnergy. Simply enter your ZIP code to explore the current rates available in your area and find plans that fit your preferences.

How to switch electricity suppliers
Energy deregulation in Illinois means that residents can choose their own electricity supplier from a competitive marketplace. This freedom allows Illinois residents to shop around for the best rates and deals, and to choose a supplier that aligns with their values, such as green energy.
The process of switching electricity suppliers in Illinois is straightforward. Firstly, you will need to research the various suppliers and compare their rates and plans. You can do this by using a free energy marketplace such as Choose Energy or SaveOnEnergy, where you can enter your ZIP code to find the best rates in your area.
Once you have selected a new Retail Electric Supplier, they will contact your existing supplier, such as Ameren or ComEd, to notify them of the switch and the switch date. You will then receive confirmation from your local electric utility, and you have seven days from the postmark date of their letter to make any adjustments.
If you are currently signed up with a supplier, be sure to check the terms of your agreement, including any early termination fees. Fixed-rate plans, for example, typically last between 12 and 36 months, and you will likely incur a fee if you cancel before the term ends.
