MDU Resources (MDU) operates diversified energy businesses, primarily in regulated energy delivery, regulated renewable energy, and pipeline and energy services. Its largest segment, Regulated Energy Delivery, provides electric and natural gas utility services to a broad base of residential, commercial, and industrial customers across several states. While other segments, like Regulated Renewable Energy and Pipeline and Energy Services, primarily serve other companies, no single corporate customer is publicly disclosed as accounting for a significant portion of MDU's consolidated revenue (typically above 10%). Therefore, describing its customer base by categories is the most appropriate way to identify its major customers.

- Residential Customers: Individuals and households that receive electric and natural gas services from MDU's regulated utility companies (Montana-Dakota Utilities Co., Cascade Natural Gas Corporation, and Intermountain Gas Company) for their homes.
- Commercial Customers: Businesses, institutions, and government entities (e.g., retail stores, offices, schools, hospitals) that utilize MDU's electric and natural gas services for their operations. This category also includes smaller businesses served by MDU's pipeline and energy services for natural gas transportation and other related energy services.
