“Our natural gas focused strategy is anchored in having the right assets in the right places to serve our nation’s growing demand for clean, affordable and abundant natural gas. This acquisition enhances our position in the western US and is complementary to our current footprint, providing us with infrastructure for natural gas deliveries across key demand markets,” said Alan Armstrong, Williams President and CEO. “With the acquisition now complete, we look forward to welcoming MountainWest employees to Williams and bringing value to our shareholders by delivering safe and reliable services to both Williams and MountainWest customers as we increase the utilisation of our existing large-scale platforms.”

With the acquisition of MountainWest, Williams expands its infrastructure network and increases its business mix of FERC-regulated natural gas transmission and storage. The acquisition expands Williams’ services to key Rockies markets, including natural gas delivery into Salt Lake City and other demand markets not previously served by Williams.
