Southwest Gas Holdings Inc. completed the rebranding of its Dominion Energy Questar Pipeline subsidiaries following the nearly $2 billion acquisition of the Rocky Mountain energy hub late last year.

Effective April 1, Dominion Energy Questar Pipeline LLC became MountainWest Pipeline LLC, according to a company release.

“The MountainWest brand is a proud reflection of the region we serve,” John Hester, president and CEO of Southwest Gas Holdings, commented in the release.

MountainWest Pipelines is an essential Rocky Mountain energy hub with more than 2,000 miles of highly contracted, FERC-regulated interstate natural gas pipelines providing transportation and underground storage services in Utah, Wyoming and Colorado.

“It feels great to have the new brand name which truly captures who we are as a company, the region we serve and the places we call home,” MountainWest President Colleen Larkin Bell said in the release. “The safe and reliable transportation of natural gas produced in the Rocky Mountain region is essential to supporting the modern lives of families and businesses.”

Southwest Gas reached an agreement with Dominion Energy last October to acquire Dominion’s Questar Pipelines unit for $1.975 billion plus the assumption of $430 million in debt. The intent to rebrand from Dominion Energy Questar to MountainWest Pipelines was originally announced Dec. 31, 2021, upon completion of the acquisition by Southwest Gas.

MountainWest’s subsidiaries and affiliates have also been renamed and rebranded as MountainWest Overthrust Pipeline LLC; MountainWest Field Services LLC; MountainWest Pipeline Services Inc.; MountainWest Energy Holding Co. LLC; MountainWest Energy Services Inc.; MountainWest Southern Trails Pipeline Co.; and MountainWest White River Hub LLC, which owns a 50% interest in White River Hub LLC.

The physical transition to the new brand will take place over a period of several months at which time all company-branded materials will reflect the MountainWest name.

“The new brand name and identity is a sign of our pride and commitment to delivering essential natural gas transportation and storage services, providing good jobs, strengthening the communities we serve and supporting the clean-energy transition. Further, the MountainWest brand stands as a symbol of our commitment to ensuring our customers and those they serve can rely on this essential fuel to provide clean, affordable energy,” Hester added in the release.
