Illinois Electric Choice Fast Facts

Historically, one company (your utility company) has provided all aspects of energy services to homes across the nation. But as competitive energy markets have matured over the last decade, alternative retail electric suppliers are now able to compete with each other over the price of electricity to power your home.

Thus far, residents in only 10 states nationwide and Washington, D.C. have the opportunity to choose a competitive electricity supplier. Customers that are located in states offering electric choice have already experienced the benefits, which include competitive energy prices, improved customer service, product innovations, and price certainty or flexibility.
