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.
