Natural Gas Expansion in South Dakota

 

NorthWestern Energy is excited to bring commercial and residential natural gas service to the quickly developing areas of South Sioux Falls, 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. Here are some frequently asked questions:

What happens when I request a natural gas connection?
A brief feasibility study will be conducted. This is to determine the construction costs required to run an underground gas line to your home and/or business. 
How much does the feasibility study cost?
There is no cost for the study. 
What happens if the study determines that it’s not economically feasible for NorthWestern Energy to install a gas line to my home or business?
We may ask you to share part of the expense required for installation, or we may not be able to serve you yet. 
Even if NorthWestern Energy agrees to run the gas line at its own expense, are there any customer costs involved?
Yes. The minimum connect fee is $90. Plus, you would be responsible for any updates needed to convert your current system to a natural gas system. 
If I have a propane system, what do I need to do to convert to natural gas?
Check with a Licensed plumbing professional to obtain an estimate for the cost of converting your propane furnace and /or water heater to natural gas. 
How does the price of natural gas compare to propane?
To use as a comparison to NorthWestern Energy’s natural gas pricing, this past winter, you would have purchased propane at $0.63 per gallon. Check our comparison chart here.
