BISMARCK — Montana-Dakota Utilities Co. and WBI Energy Inc., both subsidiaries of MDU Resources Group, announced plans for a natural gas pipeline expansion project in eastern North Dakota that will provide more natural gas to customers in Wahpeton and extend natural gas service to Kindred.

Montana-Dakota Utilities has secured utility customer contracts that require approximately 10 million cubic feet of firm natural gas service per day in Wahpeton, which exceeds the volume of gas that can be delivered on an uninterruptible basis to the city through the existing transmission pipeline.

To fulfill the additional customer demand, WBI Energy plans to construct a 60-mile, 12-inch natural gas pipeline expansion and ancillary facilities to Wahpeton.

The expansion will have capacity of 20 million cubic feet of natural gas per day and is expected to cost approximately $75 million. Upon receipt of all regulatory approvals, WBI Energy expects to begin construction in early 2024 and have the pipeline in service later that year.

As part of this project, Montana-Dakota Utilities also will extend natural gas utility service to the city of Kindred at the request of city officials and residents.
