Edison International is a publicly traded utility holding company based in Rosemead, California, that provides electric power through its principal subsidiary, Southern California Edison. The company’s operations encompass the generation, transmission and distribution of electricity to residential, commercial and industrial customers across central, coastal and southern regions of California. As a regulated utility, Edison International works under the oversight of the California Public Utilities Commission to deliver reliable service while meeting stringent safety and environmental standards.
Through Southern California Edison, Edison International serves approximately 15 million people across a diverse service territory that includes urban centers, agricultural areas and remote communities. The company’s generation mix combines owned and contracted sources, including natural gas–fired plants, hydroelectric facilities, nuclear power from third-party providers and an expanding portfolio of renewable energy projects such as solar, wind and battery storage. These resources are integrated into a transmission network that spans thousands of miles of high-voltage lines and distribution circuits, ensuring consistent power delivery even under challenging weather conditions.
Tracing its roots to the late 19th century and the pioneering work of Thomas Edison, Edison International adopted its current structure and name in the late 1980s following the reorganization of regional electric companies in California. Over the decades, the company has navigated major industry shifts—including deregulation in the 1990s, the rise of competitive wholesale markets and increasing state mandates for greenhouse gas reduction—by modernizing its infrastructure and investing in advanced grid technologies. Key initiatives have included smart meter deployment, enhanced system automation and comprehensive wildfire mitigation measures.
Edison International is governed by a board of directors and led by an executive management team focused on long-term value creation, operational excellence and sustainability. Strategic priorities include accelerating the clean energy transition, improving resiliency against extreme weather events, bolstering cybersecurity defenses and promoting community engagement. Through ongoing capital investments and collaborative stakeholder efforts, Edison International aims to support California’s energy goals while maintaining affordability and reliability for its customers.
