When choosing an electricity provider in Illinois, you may select from one of these types of plans:

Fixed-Rates Plans

Fixed-rate plans are the most prevalent type of electricity plan in Illinois. As the name suggests, your rate will be locked in for a set period, usually 12-36 months. This allows you to budget more accurately since your rate won't fluctuate with energy market prices.

Variable-Rate Plans

With a variable-rate plan, your rate will change each month based on market conditions. While these plans may offer lower rates at times, they also come with the risk of higher electricity prices when the market is tight.

100% Green Energy Plans

If you're someone who cares about the environment, a 100% Green Energy Plan could be the perfect choice for you. These renewable energy plans offset your energy usage by purchasing Renewable Energy Credits (RECs). RECs reflect the generation of renewable energy sources like solar or wind. By choosing this type of plan, you can ensure that your energy consumption is supporting renewable energy projects.

Yes, Illinois electric rates are expected to increase. For ComEd customers, a significant supply rate hike of about 45 percent is anticipated starting June 1, 2025, driven by a record spike in the 2024 PJM capacity auction, where costs rose from $2.2 billion to $14.7 billion. This could add $7.50 to $10 per month for a customer using 500 kWh, according to the Citizens Utility Board. This would increase a 12-month plan by $90 to $120, assuming a 500 kWh usage. If you're on the higher end at 1,000 kWh usage, expect this to add $180 to $240 to your yearly bill. Additionally, a $606 million delivery rate increase took effect on January 1, 2025, impacting monthly bills by raising fixed charges and per-kWh rates. For Ameren customers, delivery rates also rose by $309 million in January 2025, adding roughly $4.33 monthly for the average user (+$50 per year).
