Southwest Gas Holdings, Inc. SWX is advancing infrastructure investments to enhance system safety, reliability and service quality across its regulated operations. These initiatives also help accommodate customer needs and improve the resilience of its natural gas distribution network.
SWX plans to invest approximately $1.25 billion in 2026, including $925 million in Utility expenditures and $325 million for the Great Basin 2028 Expansion Project, as part of its $6.3 billion capital investment plan for 2026 through 2030. It continues to target 9.5-11.5% annual rate-base growth and 12-14% annual adjusted earnings per share growth through 2030.
Southwest Gas is expanding and strengthening its infrastructure to meet rising demand, supporting rate-base growth and creating opportunities for timely regulatory recovery of investments. In the first half of 2026, SWX invested $520 million in infrastructure modernization and expansion.
The Great Basin 2028 Expansion Project provides another significant growth opportunity. Binding precedent agreements now cover approximately 1 billion cubic feet per day (Bcf/d) of contracted demand, while SWX has received expressions of interest for another 1.8 Bcf for potential projects serving 2029-2035 demand. The project’s estimated capital investment has increased to approximately $2.3 billion, with potential annual incremental margin of $270-$300 million after completion.
Overall, SWX’s infrastructure investments, regulatory recovery mechanisms and Great Basin expansion could support rate-base expansion and contribute to long-term growth.
