The Power of Membership


Tri-County Electric Cooperative, in conjunction with the Association of Illinois Electric Cooperatives and SDS Research, will be conducting a written survey that will be sent to random members in our system in October and November. If you receive a questionnaire, please complete it by mail, or online. The information you provide will help us to better serve you in the future, and you’ll be entered into a drawing for one of five $100 bill credits. 

Tri-County Electric Cooperative has been committed to providing our member-owners with safe, adequate and and reliable electric service, superior customer service and innovative energy solutions, all at reasonable prices.

The not-for-profit cooperative was incorporated in 1938 to provide electric service to residents in the rural areas of Jefferson, Marion and Washington Counties in Southern Illinois.

The Tri-County neighborhood offers many recreational opportunities at Rend Lake as well as educational opportunities through two colleges: Rend Lake College at Ina and Kaskaskia College at Centralia.
