- Sempra is a North American energy infrastructure company primarily engaged in developing, building, and operating electric and natural gas transmission and distribution infrastructure. The company provides core services through its operating segments: Sempra California, encompassing Southern California Gas Company (SoCalGas) and San Diego Gas & Electric (SDG&E); Oncor Electric Delivery Company in Texas; and Sempra Infrastructure, which focuses on liquefied natural gas (LNG), net-zero solutions, energy networks, and clean power projects across North America and Mexico. Sempra manufactures, sells, and operates energy delivery systems, including electric utilities, natural gas utilities, LNG export facilities, wind power projects, and emerging low carbon technologies such as hydrogen fuel production and carbon capture and storage. The company serves nearly 40 million consumers and manages extensive energy networks in the United States and internationally.
Founded in 1998 and headquartered in San Diego, California, Sempra has evolved through strategic divestitures and investments to concentrate on energy infrastructure growth and sustainability. Recent major changes include a rebranding in 2021 from Sempra Energy to Sempra to emphasize its infrastructure focus. In 2024 and 2025, Sempra announced a record five-year capital plan totaling $48 billion aimed at expanding its utility rate base, improving safety, reliability, and transitioning to cleaner energy sources. Significant transactions in 2025 include the agreement to sell a 45% equity stake in Sempra Infrastructure Partners to a consortium led by global investment firm KKR and Canada Pension Plan Investment Board for $10 billion, enhancing financial strength and supporting capital recycling efforts. Sempra Infrastructure is advancing major LNG expansion projects such as the Cameron LNG facility in Louisiana and the Port Arthur LNG facility in Texas, with final investment decisions expected soon for additional liquefaction trains and plant capacity expansions. The company continues to develop renewable projects, including the Cimarron wind project, underlining its commitment to clean energy solutions.
Sempra’s business segments cover regulated electric and gas utilities in California and Texas, LNG export and infrastructure development in North America, and clean energy infrastructure with a focus on reducing carbon emissions. Its infrastructure projects include LNG terminals, renewable energy generation, hydrogen production, and advanced carbon capture technologies. The company maintains strategic partnerships and offtake contracts with major energy firms such as ConocoPhillips to support LNG facility growth. Sempra’s diversified portfolio and ongoing projects position it as a leading utility growth enterprise focused on delivering safe, reliable, affordable, and cleaner energy solutions to its extensive customer base. The company operates primarily in the United States and Mexico with ambitions to expand its infrastructure footprint globally through investment and innovation initiatives.
Sempra is led by Chairman and CEO Jeffrey W. Martin and had total assets exceeding $96 billion as of 2024, with a workforce of over 20,000 employees. Its subsidiaries include Southern California Gas Company, San Diego Gas & Electric, Oncor Electric Delivery Company, and Sempra Infrastructure—a platform formed in 2021 through the merger of Sempra LNG and IEnova, geared toward next-generation energy infrastructure development.
Overall, Sempra combines utility operations, large-scale LNG export facilities, and renewable energy initiatives to serve diverse energy needs across North America, while pursuing strategic transactions and capital plans that enhance financial resilience and support the global transition to lower-carbon energy systems.
