Overview
Sempra is a San Diego-based North American utility holding company whose businesses develop, own and operate electric, natural-gas and related energy infrastructure. Its principal operating platforms are the regulated California utilities Southern California Gas Company (SoCalGas) and San Diego Gas & Electric (SDG&E), the Texas transmission and distribution utility Oncor Electric Delivery Company, and Sempra Infrastructure, which develops energy infrastructure projects across the United States and Mexico. Collectively, the company’s operating businesses serve or connect tens of millions of consumers and businesses, making Sempra one of the largest utility holding companies in the United States. The company was created in 1998 through the merger of Pacific Enterprises, the Los Angeles-based parent of SoCalGas, and Enova Corporation, the parent of SDG&E. The resulting company was initially known as Sempra Energy. During its earlier expansion, Sempra acquired utility interests in Chile and Peru and built businesses spanning power generation, natural-gas storage, pipelines, renewables, energy trading and liquefied natural gas. This international and diversified phase gave the company exposure to multiple parts of the energy value chain, but it also brought regulatory and litigation challenges, including claims connected with the California electricity crisis of 2000–2001. From 2018 onward, Sempra increasingly concentrated on North American infrastructure. It acquired a majority interest in Oncor in 2018, expanded its Texas transmission portfolio through the InfraREIT transaction and its investment in Sharyland Utilities, and exited its South American utility businesses through the sales of Luz del Sur in Peru and its Chilean operations. The divestitures allowed management to emphasize regulated electric and gas networks, energy transportation and large-scale infrastructure development rather than maintaining a geographically broad portfolio of international utilities and merchant-energy assets. Sempra Infrastructure was formed in 2021 by combining the company’s LNG and Mexican infrastructure operations. Its activities include liquefied-natural-gas export and import infrastructure, energy networks, clean power and projects intended to support lower-carbon energy systems. Major projects associated with the platform include Cameron LNG in Louisiana, Port Arthur LNG in Texas and proposed LNG facilities on Mexico’s Pacific coast. Sempra’s regulated utilities are also pursuing emerging technologies and decarbonization initiatives. SoCalGas has proposed Angeles Link, a large-scale green-hydrogen infrastructure concept, while SDG&E has invested in grid modernization, resilience and cleaner electricity integration. In 2021, the company dropped “Energy” from its corporate name and adopted the Sempra brand to emphasize infrastructure delivery rather than a broad energy-trading identity. After Russia’s invasion of Ukraine in 2022, Sempra Infrastructure entered agreements with European energy companies related to U.S. LNG supplies, positioning its export projects as part of efforts to diversify European gas supply. In 2024, Sempra described a five-year capital plan of approximately $48 billion for 2023–2028, directed toward safety, reliability, regulated networks and cleaner-energy infrastructure. Sempra reported more than $96.2 billion in total assets and over 20,000 employees for 2024. Jeffrey Martin has served as chairman and chief executive officer since May 2018.
History
Sempra originated in the 1998 merger of Pacific Enterprises and Enova Corporation. Pacific Enterprises controlled Southern California Gas Company, while Enova was the parent of San Diego Gas & Electric. Their combination created Sempra Energy, a utility holding company headquartered in San Diego and centered initially on regulated gas and electric operations in Southern California. The company expanded internationally in 1999 by acquiring Chilquinta Energía in Chile and Luz del Sur in Peru. It also developed businesses in power generation, natural-gas storage, pipelines, renewable generation, LNG and energy commodities. In the early 2000s, Sempra Energy Resources completed power-plant projects in Arizona, California and New Mexico. This period diversified Sempra beyond traditional utility service but exposed it to merchant-energy and international-market risks. Sempra became involved in litigation and regulatory disputes arising from the California electricity crisis. Allegations included manipulation of gas supplies and electricity contracts, as well as electricity-price gouging. The company reached a $377 million settlement concerning gas-supply claims in 2006 and paid $410 million in 2010 to resolve electricity-price claims. In both matters, Sempra did not admit wrongdoing. In 2007, the company created the Sempra Energy Foundation, later renamed the Sempra Foundation. The foundation supports climate action, economic opportunity, diversity and inclusion, disaster relief and employee community engagement. During the late 2010s, Sempra began reducing exposure to non-core businesses. It divested U.S. renewable and non-utility gas-storage assets during 2018 and 2019 and redirected attention toward North American transmission and distribution infrastructure. A major strategic step came in 2018, when Texas regulators approved Sempra Energy’s acquisition of a majority stake in Oncor. Oncor became a central component of Sempra’s North American utility portfolio, operating a large electric transmission and distribution network in Texas. In 2019, Sempra and Oncor acquired InfraREIT, while Sempra also acquired a 50 percent interest in Sharyland Utilities. These transactions expanded the company’s regulated Texas infrastructure position. Sempra completed its withdrawal from South America in 2020. It sold Luz del Sur in Peru for approximately $3.59 billion and its Chilean businesses to State Grid International Development for approximately $2.23 billion in cash. The transactions reinforced the company’s stated preference for North American regulated networks and infrastructure development. In 2021, Sempra Energy adopted the shorter Sempra name and launched a refreshed visual identity. The company explained the rebrand as a way to emphasize infrastructure that delivers energy. That year, Sempra also combined Sempra LNG and IEnova into Sempra Infrastructure. The new platform develops LNG export and import facilities, energy networks, clean power and lower-carbon solutions in the United States and Mexico. Sempra separately sold PXiSE Energy Solutions, a grid-management technology business that had been partly owned with Mitsui. Sempra Infrastructure’s portfolio includes Cameron LNG in Louisiana, the Port Arthur LNG project in Texas and proposed LNG facilities on Mexico’s Pacific coast, including Energía Costa Azul LNG, Vista Pacífico LNG and Salina Cruz. The regulated utilities have pursued modernization and decarbonization initiatives. SoCalGas has proposed Angeles Link, a large green-hydrogen infrastructure system, while SDG&E continues to focus on grid reliability, resilience and integration of cleaner electricity. After Russia’s invasion of Ukraine in 2022, Sempra Infrastructure announced agreements with European energy companies concerning U.S. LNG, presenting its projects as potential contributors to supply diversification. In 2024, Sempra described a record five-year capital plan of approximately $48 billion for 2023–2028. The plan targeted safety, reliability, network expansion and cleaner energy infrastructure. Jeffrey Martin has been chairman and chief executive officer since May 2018.
