Intermountain Rural Electric Association currently has 200 employees who serve nearly 139,000 consumers. This is the highest consumer to employee ratio of any large cooperative in the United States. IREA is the largest of the 22 cooperatives in Colorado and the eleventh largest co-op in the United States.

Although the industry standard for outages is 5 hours per customer per year, IREA has consistently achieved an outage rate of less than two hours, and occasionally less than one hour per year. IREA also has among the lowest electric rates of any cooperative or investor-owned utility in the state. These accomplishments truly make IREA a leader in the industry.
