WBI Energy’s Dakota Pipeline Moves Forward

Open season for capacity commitments announced

BISMARCK, N.D.--()--WBI Energy, Inc., the pipeline and energy services subsidiary of MDU Resources Group, Inc. (NYSE: MDU), announced that planning for a 375-mile natural gas pipeline stretching from western North Dakota to northwestern Minnesota is underway and an open season seeking capacity commitments has begun.

“The Dakota Pipeline offers another avenue to move Bakken-produced natural gas out of the area and complements our other ongoing activities to build connections to several natural gas processing facilities,” said David L. Goodin, president and CEO of MDU Resources. “The increase in natural gas pipeline capacity out of the region will provide additional transportation opportunities for new production as it comes on line, as well as more capacity for natural gas captured through industry’s efforts to reduce the flaring of this valuable resource.”

North Dakota Governor Jack Dalrymple has been concerned about the amount of natural gas flaring in the state and has asked an industry task force to provide recommendations. “We are committed to working with WBI Energy and the entire energy industry so that we continue to reduce flaring, add value to our energy resources and help meet the nation’s energy needs,” Dalrymple said. “This pipeline is part of the solution and I commend MDU Resources and WBI Energy for their commitment to North Dakota and to the responsible development of our energy resources.”

Rapidly growing natural gas production in western North Dakota, coupled with increasing demand from industrial, commercial and residential markets in eastern North Dakota, Minnesota, Wisconsin, Michigan and other Midwest markets, has generated strong interest in the Dakota Pipeline from potential shippers across the region.

“This project provides access to markets in the Mid-Continent and Great Lakes regions of the U.S. We have been encouraged by the interest the marketplace has shown in this project to date,” said Steven L. Bietz, president and CEO of WBI Energy. “Through the open season process, we intend to secure capacity commitments for the Dakota Pipeline and begin the process for obtaining the necessary permits and regulatory approvals.” An open season is pipeline industry terminology for a time period when interested shippers make binding bids for firm transportation capacity on the new pipeline.

The proposed route will provide access to interconnections with pipelines operated by Great Lakes Gas Transmission Limited Partnership, Viking Gas Transmission Company and, potentially TransCanada Pipelines Limited. The interconnections would be at a point in northwestern Minnesota.

The Dakota Pipeline has been designed to initially transport approximately 400 million cubic feet per day of natural gas and, depending on user commitments, could be expanded to more than 500 MMcf/d. At a transport volume of 400 MMcf/d, the pipeline carries enough natural gas annually to provide the needs of 1.3 million homes.

The project investment for the proposed 375-mile pipeline system is estimated to be approximately $650 million. The majority of the new pipeline would be comprised of 24-inch diameter pipeline and includes two new compressor stations.

Following receipt of the contractual capacity commitments from the open season and the granting of the necessary permits and regulatory approvals, construction on the new pipeline could begin in 2016 with completion expected in 2017.
