100th Anniversary
Celebrating 100 Years
MDU Resources has come a long way since its start in 1924 as a small electric utility serving a handful of small communities on the Montana and North Dakota border. Over 100 years, MDU Resources has grown into a corporation with operations across the United States. As the company celebrates its centennial anniversary in 2024, it’s an exciting time to reflect on the past century of growth and success that has defined MDU Resources’ remarkable journey.
