Strategy and assets

At Sempra Energy, we work to deliver robust growth within our three primary platforms — U.S. utilities;
international utilities; and long-term, contracted energy infrastructure.

Sempra Energy, based in San Diego, is a Fortune 500 energy services holding company with 2015 revenues of more than $10.2 billion. The Sempra Energy companies’ 17,000 employees serve more than 32 million consumers worldwide.

Sempra Energy was created in 1998 by the merger of the parent companies of San Diego Gas & Electric® and Southern California Gas Company, two investor-owned utilities with rich histories dating back more than a century. Today, two additional businesses – Sempra U.S. Gas & Power and Sempra International – invest in, develop and operate critical energy infrastructure and provide gas and electricity services in North and South America. Our subsidiaries’ infrastructure includes 124,440 miles of natural gas pipelines and 49,348 miles of electric transmission and distribution lines; two liquefied natural gas receipt terminals, 179 billion cubic feet of natural gas storage, five natural gas-fired power plants; and nearly 4,800 acres of solar plants and 735 wind turbines, which they operate with partners.

At Sempra Energy, our objective is to increase shareholder value by developing and operating long-term-contracted energy infrastructure assets and regulated utilities in a safe and reliable manner. The key components of our business strategy include the following three disciplined growth platforms:

  • U.S. utilities;
  • International utilities;
  • Long-term-contracted energy infrastructure (including liquefied natural gas [LNG], pipelines and renewable energy)

This strategy has been shaped by the rising demand for lower-carbon sources of energy: We place a priority on developing natural gas and renewable energy infrastructure, and we focus on improving energy efficiency and innovating for the future. This helps us meet the energy needs of our customers and maintain a stable rate of growth in an increasingly carbon-constrained world.

Sempra Energy’s values and code of conduct guide the implementation of this strategy: What we do is important, but how we do it is even more critical. We strive to be a responsible partner: ethical, respectful, high-performing and forward-looking. We engage with our stakeholders – our customers, employees, investors, business partners, regulators and the communities we serve – and consider and incorporate their feedback when we can, building trust and strengthening relationships.
