Market Overview


  • PJM – ComEd territory
  • Midcontinent ISO (MISO) – Rest of state.

Competition Enabler & Key Statute(s):

  • Legislative – Electric Service Customer Choice and Relief Law of 1997 (A. 90-561)
  • Statute(s) – 220 ILCS 5 Public Utilities Act.

Utility Territories with Retail Competition:

Four investor-owned public utilities provide electric service to retail customers in the State of Illinois:

  • Ameren Illinois Company
  • Commonwealth Edison Company
  • MidAmerican Energy Company
  • Carmel Public Utility Company

Customers in the Ameren Illinois, ComEd, and MidAmerican service territories have the ability to choose who provides the supply portion of their electric service. Electric supply may be sold by either the utility or Retail Electric Suppliers (RESs). Currently there is only one RES registered to sell electricity in the MidAmerican service territory. Customers in Mt. Carmel Public Utility’s service territories also have the right to choose a retail electric supplier. However, no suppliers have registered with Mt. Carmel to serve these customers.

Municipal systems and electric cooperatives also provide electric service in Illinois; these municipal systems and electric cooperatives are not subject to regulation by the Illinois Commerce Commission.

Retail Competition Background:

The Electric Service Customer Choice and Rate Relief Law of 1997 restructured the state’s electric service industry to allow for competition among suppliers. The 1997 Law established a fixed timetable for the introduction of electric retail choice in Illinois, beginning with approximately 64,000 non-residential electric customers, or about one-seventh of all non-residential customers, on October 1, 1999. An additional 609,000 non-residential customers became eligible for retail choice on January 1, 2001. An estimated 4.4million Illinois residential customers became eligible for the retail choice program in May 2002. All customer classes are now eligible to choose alternative suppliers. At the end of December 2015, 86 suppliers were certified to serve nonresidential customers, although 10 of those sought Commission authority to only serve themselves or affiliates. Sixty-four suppliers were certified to serve residential customers. As of November 30, 2016, over 1.9 million residential customers were purchasing power and energy from a Retail Electric Supplier (RES) and approximately 280,000 non-residential customers in Illinois were purchasing power and energy from a RES. The percentage of RES usage among non-residential customers with a peak demand above one megawatt in the service territories of Ameren Illinois and Commonwealth Edison remains around 90 percent.

Municipal Aggregation:

Vistra inherited Dynegy’s municipal aggregation services in Illinois as part of the merger. The Dynegy brand serviced the northern IL (ComEd) territory while the Homefield brand was used for the southern IL (Ameren) territory. Beyond commodity, Dynegy and Homefield also offered Demand Response, Peak Load Contribution (a demand ratchet reduction program) and renewable energy.
