Sempra: The Evolution of an Energy Infrastructure Giant
From its inception as a strategic merger to its current status as a leader in energy delivery, Sempra has undergone a significant transformation. Originally focused on a broad utility portfolio, the company has pivoted its strategy to prioritize the critical infrastructure that powers North America, adapting to shifting economic landscapes and global energy demands.
The Foundation and Early Expansion (1998–2018)
Sempra was established in 1998 through the merger of two major entities: the Los Angeles-based Pacific Enterprises (the parent company of SoCalGas) and Enova Corporation (the parent company of San Diego Gas & Electric). This merger created a powerful utility foundation in California.
Seeking growth in emerging markets, the company expanded into South America in 1999 by acquiring Luz Del Sur in Peru and Chilquinta Energia in Chile. By 2003, the company's power generation arm, Sempra Energy Resources, had completed three advanced power plant projects across Arizona, California, and New Mexico.

Legal Challenges and Corporate Responsibility
The company's growth was not without controversy. Sempra faced lawsuits alleging the manipulation of electricity contracts and natural gas supplies during the 2001 California electricity crisis. While the company never admitted wrongdoing, it paid $377 million in 2006 to settle gas supply claims and an additional $410 million in 2010 to settle electricity price gouging claims.
In 2007, the company established the Sempra Foundation, a 501(c)(3) private foundation. To date, the foundation has invested over $50 million into climate action, disaster relief, diversity and inclusion, and economic prosperity, while matching employee contributions to eligible charities.
Strategic Pivot and Modern Era (2019–Present)
Starting in 2019, Sempra began a disciplined shift in its business model. After being added to the Dow Jones Utility Average in January 2019, the company divested its non-utility natural gas storage assets and U.S. renewables, generating approximately $2.5 billion in cash. This move allowed Sempra to refocus on transmission and distribution infrastructure—the physical systems used to move energy from producers to consumers.
The company aggressively expanded its footprint in Texas, acquiring a majority stake in Oncor for $9.45 billion in 2018, followed by the acquisition of InfraREIT and a 50% interest in Sharyland Utilities in 2019.

Global Realignment and Rebranding
By 2020, Sempra completed its exit from the South American market, selling Luz del Sur for $3.59 billion and its Chilean businesses to China's State Grid International Development Ltd for $2.23 billion. In June 2021, the company officially rebranded from "Sempra Energy" to simply Sempra, updating its logo to emphasize its core focus on energy delivery infrastructure.
In response to the 2022 Russian invasion of Ukraine, Sempra Infrastructure entered agreements with European energy firms to provide U.S. liquefied natural gas (LNG)—natural gas cooled to a liquid state for easier transport—to reduce Europe's reliance on Russian energy.
Future Outlook and Capital Investment
Sempra has committed to a record five-year capital plan of $48 billion for the period of 2023–2028. This investment is designed to bolster reliability, improve safety, and support the delivery of cleaner energy sources across its growth platforms in California and Texas.
