CORE, formerly known as Intermountain Rural Electric Association (IREA), is a member-owned electric utility cooperative that serves members in a 5,000-square-mile area in central Colorado. CORE provides reliable and affordable power to more than 300,000 consumers, making it the largest electric distribution cooperative in Colorado, and one of the largest in the U.S. As a member-owned cooperative, CORE operates on a nonprofit basis; earnings exceeding expenses are invested in the facilities used to provide electric service and are booked as member equity.
