Rooted in local values and powered by community spirit, CORE Electric Cooperative has been lighting the way since 1938. What began with a small group of residents has grown into a trusted energy provider serving more than 180,000 members across Colorado. As the state’s largest electric cooperative and one of the largest in the nation, we’re proud to deliver dependable, innovative energy solutions that keep homes, businesses, and communities thriving.

Our commitment goes beyond electricity. We believe in energizing the places we call home by supporting hundreds of charitable programs, local nonprofits, and community partnerships. Through innovation, collaboration, and care, CORE connects lives and empowers communities to build a brighter, more sustainable future together.
