Southwest Gas Holdings (SWX) reported on June 5 that an open season for a natural gas pipeline network expansion in Northern Nevada brought in strong interest, enough for a capital investment worth up to $1.2 billion.

The company began a binding open season on Jan. 28 to gauge interest in the project, scheduled to begin service in the latter part of 2028. SWX said that the response was firm enough to extend the open season from the original end date in April to May 28.

"The level of interest we received validates both the importance of our infrastructure and the ongoing need for dependable energy delivery in Northern Nevada," said Karen Haller, CEO of Southwest Gas Holdings, in the announcement.

SWX is in the business of purchasing, distributing and transporting natural gas. The expansion project is managed through its subsidiary Great Basin Gas Transmission Co., which owns an 898-mile interstate gas pipeline system that runs through Idaho, Nevada and California.

Based on the open season results, SWX said the expansion project would add 1.25 Bcf/d of capacity to the network and provide a capital investment opportunity from $800 million to $1.2 billion.

SWX plans to move forward with contract negotiations for capacity on the network and garner final approval from the Federal Energy Regulatory Commission to begin construction.
