NorthWestern Energy is a regional energy company serving electric and natural gas across western and central Montana, eastern South Dakota and several communities in Nebraska, while also proudly serving Yellowstone National Park.

Utility operations consist of regulated electric and natural gas distribution, transmission and energy supply. In addition, NorthWestern considers electric transmission and generation opportunities, as appropriate.

Generation

Natural Gas

Natural gas is mined from pockets underground. Most natural gas used by NorthWestern Energy comes from Wyoming or Canada. It is mined and transported via pipeline to NorthWestern-owned gate stations.

Electricity

NorthWestern generates power using hydroelectric dam facilities, wind turbines, solar panels, natural gas generators, and coal powered generators. If NorthWestern does not generate enough to meet customer demand, electricity must be purchased from the market.

Transmission and distribution

Natural gas 

A series of underground pipes carry natural gas to NorthWestern-owned gate stations. NorthWestern adds mercaptan to the odorless gas to give it the rotten egg smell. Smaller pipes carry the prepared gas to each community. From there, it is distributed to homes and businesses.
