Montana-Dakota Utilities

Montana-Dakota Utilities Co. was created in 1924 to serve a handful of small farm communities in the area. Since then the company has grown into a large regional energy supplier. During those years of growth, we’ve changed our name a few times, acquired a number of smaller companies and progressed side-by-side with those we serve. Today, we’re a division of MDU Resources Group, Inc., a diversified energy company based in Bismarck, N.D. We provide retail natural gas and/or electric service to parts of Montana, North Dakota, South Dakota and Wyoming. Our service area covers more than 168,000 square miles (5.5 percent of the continental United States), and we serve about 355,000 customers.
