South Dakota Gas Expansion

A map showing our natural gas expansion in the Sioux Falls area.

NorthWestern Energy is excited to bring commercial and residential natural gas service to the quickly developing areas of South Sioux Falls - the Tea and Harrisburg areas. Our gas main extension project in the area began in the early 2000s followed by a major expansion in 2015. That growth has led into our latest expansion. We are proud to be a part of these communities and to be the trusted regional supplier to the area.

As part of our long-term commitment to Tea and Harrisburg, NorthWestern Energy has been at work for nearly a decade making natural gas available to homes and businesses still reliant on propane and other energies. Our recent work has concentrated on the Bakker Crossing development and along 271st street east of Interstate 29.
