Energy Deregulation in Illinois

In 1995 Larry D. Habb, president and chief executive officer of Illinois Power Co., the state’s second largest power company, began the pushing for energy deregulation as method of saving energy and money. Two years later, Illinois lawmakers passed the the Illinois Electric Service Customer Choice and Rate Relief Law of 1997 that kicked off deregulation in Illinois.

What is the difference between a Utility and an Energy Provider?

Utilities are the entities in charge of the operation and maintenance of the energy infrastructure, like wires and towers. The local utilities in Illinois include Ameren, Cedar Point Light and Power, Central Illinois Light Company, Commonwealth Edison Company, Electric Energy, Illinois Power Company, and Union Electric Company.  Each utility is responsible for transporting electricity from the generators to residential homes and businesses in their specific region of Illinois. Illinois energy customers can find a full list of Certified Electric Illinois utilities here.

Energy providers in Illinois, like Direct Energy, Entrust, and Public Power are the competitive energy retailers. Each energy provider buys energy from the wholesale market (the generators) and then re-sells it to consumers (homeowners, renters, and businesses).

In most cases, the consumer, the homeowner, renter, or business, signs a contract with an energy provider for a specific energy plan. The basic energy plan details the rate class, the energy rate per kWh, the contract term length (6, 12, 24, 36 months), and other contract terms like cancellation fee policy.
