Powering California

Helping meet California’s growing energy needs

Sempra California utilities deliver safe, reliable and more affordable energy to roughly 25 million consumers in Southern and Central California. Our approach is grounded in long-term investment in energy infrastructure, strengthening grid resilience, supporting consistent service during extreme weather and helping manage costs for customers.

California is the largest economic market in the U.S., representing nearly 15% of national GDP, and leads the U.S. in total installed solar power capacity and electric vehicle adoption.* San Diego Gas & Electric (SDG&E) and Southern California Gas Company (SoCalGas) operate under a regulated framework that allows them to invest in infrastructure and recover costs over time. This supports ongoing upgrades while maintaining oversight and accountability for customers and aligns with Sempra's long-term focus on regulated utilities. Together, our California utilities represent approximately $32 billion in energy infrastructure*. 

California is known for advancing innovation and new technologies, a spirit embraced by our California utilities that are investing in diverse sources of energy, battery storage, predictive technologies and other tools designed to reduce the impact of severe weather events and help protect the safety of the communities we serve.
