NWE

Northwestern Energy Group, Inc.

A utility that supplies electricity and natural gas to homes and businesses across Montana, South Dakota, and parts of Nebraska, NorthWestern Energy also powers Yellowstone National Park. It traces its roots to the Northwestern Public Service Company, founded in 1923 when two Nebraska and two South Dakota electric utilities merged, choosing "Northwestern" to reflect the region it serves. A fun quirk: it provides electricity to Yellowstone, the world's first national park.
