- Edison International (NYSE: EIX; LSE: 0IFJ) operates as a utility holding company primarily engaged in the generation, transmission, and distribution of electricity through its principal subsidiary, Southern California Edison Company (SCE), which serves approximately 15 million people across a 50,000-square-mile territory in Central, Coastal, and Southern California. SCE provides regulated electric utility services including power procurement, transmission, distribution, and customer service; energy storage solutions; distributed energy resources such as solar, battery storage, and demand response programs; and advanced grid management technologies encompassing smart meters, grid modernization, and cybersecurity services. The company also engages in competitive businesses through subsidiaries like Edison Energy, offering energy management solutions, renewable energy procurement, and sustainability consulting to commercial and industrial customers.
Headquartered in Rosemead, California, Edison International was originally incorporated in 1909, with its modern corporate structure tracing back to 1987 following the restructuring of Southern California Edison. The company operates predominantly in the United States, with a strategic focus on California, and serves a diverse customer base including residential, commercial, industrial, and governmental entities. It maintains a portfolio of wholly-owned and rate-regulated assets, including hydroelectric, natural gas-fired, and solar generation facilities, alongside investments in emerging clean energy technologies.
In recent developments, Edison International advanced its clean energy transition through SCE's completion of several large-scale battery storage projects, including the 2024 operationalization of the 460 MW Alamitos Energy Center hybrid battery-gas facility and expansions to existing storage sites totaling over 1,000 MW by mid-2025. The company secured regulatory approval in late 2024 for a $5.5 billion wildfire mitigation capital plan, incorporating advanced vegetation management, undergrounding of power lines, and public safety power shutoff enhancements, reflecting a strategic shift toward climate resilience amid California's increasing wildfire risks. Additionally, Edison International announced a 2025 partnership with Tesla for next-generation Megapack deployments to support grid reliability and renewable integration, alongside a $1.2 billion acquisition of a portfolio of community solar projects to expand distributed generation capacity.
