Your Cooperative

Powering Our Communities Since 1939

For more than 85 years, Southwestern Electric Cooperative, Inc. has proudly delivered safe, reliable, and affordable electric service to the homes, farms, businesses, and communities we serve throughout southwestern Illinois. Headquartered in Greenville, Illinois, we are more than an electric utility. We are a member-owned cooperative dedicated to improving the quality of life for the people and communities we serve.

Unlike investor-owned utilities, Southwestern Electric Cooperative is a not-for-profit electric cooperative. That means every decision we make is guided by what is best for our member-owners, not by generating profits for outside investors or shareholders. Our focus is on providing dependable electric service, investing in our electric system, and delivering exceptional value to the members who own the cooperative.

Today, Southwestern Electric provides electric service to approximately 25,000 members across a diverse and growing service territory that includes portions of Bond, Clay, Clinton, Effingham, Fayette, Macoupin, Madison, Marion, Montgomery, Shelby, and St. Clair Counties. From rural farms and small communities to local businesses and growing industries, we are proud to serve the people and places that make Southwestern Illinois home.
