Expert brokerage services helping Illinois businesses reduce natural gas costs through deregulation
Illinois businesses can save 20-40% on natural gas by choosing an alternative supplier through the state's deregulated market. The Illinois Commerce Commission oversees supplier choice programs, allowing commercial customers to select from dozens of licensed suppliers while their local utility continues to deliver gas safely and reliably.
Illinois has been a leader in natural gas deregulation since the late 1990s. The state's competitive market allows commercial and industrial customers to choose their natural gas supplier while their local utility—such as Nicor Gas, Peoples Gas, or Ameren Illinois—continues to handle delivery, billing, and emergency services.

When you switch suppliers, only the supply portion of your bill changes. Your utility continues to deliver gas, read your meter, respond to emergencies, and often handle billing. The transition is seamless with no service interruption.
