Illinois Electric and Gas Service Areas

Illinois is known as the Land of Lincoln and sits at the center of the American heartland. That’s why we strive to ensure our Customers in this great state get a high level of care and great product selection from their Illinois electricity company. That’s also why we work closely with leading power transmission and distribution companies to achieve that goal.

We’ll never let the American heartland down.
