A Message from Our CEO

Over the past year, demand for safe, reliable and affordable natural gas remained high. The continued expansion of natural gas services into Mesquite and Spring Creek, Nevada, has delivered new, long-term economic development opportunities to these previously unserved communities. Several manufacturing companies and federal agencies have also turned to Southwest Gas for energy solutions that help them reduce their emissions, lower costs and enhance resiliency.
