Black Hills Energy

Beginning with the Black Hills Gold Rush, generations of families have relied on us. And we’ve been ready.

We were there when electric lights first lit up the night in Deadwood. We helped fuel a changing economy and experienced how the modern miracle of energy can change how we live.

Since 1883 energy has moved us forward. And it will shape the future.

We partner with our communities and customers, providing the kind of energy that fuels those areas and the lives of those we serve.


Mt. Rushmore KOA

Set up camp at the closest KOA Campground to Mount Rushmore National Memorial at Mount Rushmore KOA Resort at Palmer Gulch, the only place where you can wake up to presidential views and fall asleep under a sky full of stars.

More than just a campground, this full-scale camping resort blends adventure, relaxation, and resort-style amenities for a vacation that's as epic as the landscapes around you. Our RV sites accommodate rigs up to 90 feet, and our pools are open from Memorial Day to Labor Day.

With your hosts, Recreational Adventures Co., you'll be at the center of all the Black Hills has to offer.
