Montana Dakota Utilities

You’re probably familiar with the expression “A light bulb went on,” meaning someone just had a good idea. Well that’s what happened – quite literally – on the border between Montana and North Dakota in 1924. Montana-Dakota Utilities Co. was created that year 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.
