Southern California Edison (SCE)
SCE is a subsidiary of Edison International, a public utility holding company based in Rosemead, California. Edison International is committed to reaching net-zero greenhouse gas emissions by 2045 and supports California's climate goals through a safe, reliable, and affordable clean energy transition. SCE shares this commitment to sustainability and is taking steps to make clean energy more accessible and reliable for its customers. This includes providing electricity rebates and incentives for lighting, food service technology, HVAC, air conditioning, and other electric appliances and systems to help manage electricity costs. SCE also offers a "green rate" option, allowing customers to obtain their electricity entirely from renewable sources.
SCE has a history of research and innovation in the energy arena, often collaborating with other companies and government entities. For example, in 2014, SCE installed the Tehachapi Energy Storage Project, composed of more than 600,000 lithium-ion battery cells, to test storing power generated from wind turbines. In the same year, SCE announced a partnership with Ice Energy to provide more efficient energy storage by freezing water at night when electricity is cheaper. SCE also launched its "Charge Ready" program, which aims to increase the availability of charging ports for electric vehicles and includes a rebate program for electric vehicle purchases.
In addition to its electric business, SCE operates the sole gas and water utilities on Santa Catalina Island under the names Catalina Island Gas Company and Catalina Island Water Company. SCE was officially incorporated in 1909, but its origins date back to the mergers and acquisitions of several small predecessor companies, some of which date back to 1886. One notable predecessor company was Pacific Light and Power, founded by business magnate Henry E. Huntington, which executed the Big Creek Hydroelectric Project, one of the largest hydropower systems in the United States.

SCE's history and origins
Southern California Edison (SCE) is the largest subsidiary of Edison International, which is one of the nation's largest electric utility holding companies. SCE has been providing electric service in the region for 136 years, delivering power to approximately 15 million people across a 50,000-square-mile area of Central, Coastal, and Southern California.
The origins of SCE lie in the early 20th century, around 1908, with the scheme of business magnate Henry E. Huntington and hydraulic engineer John S. Eastwood. They envisioned a vast complex of reservoirs to be constructed in the Sierra Nevada Mountains of central California, which would become one of the largest hydropower systems in the United States, known as the Big Creek Hydroelectric Project. Huntington founded Pacific Light and Power to execute this project, and it was one of the predecessor companies to SCE, along with Edison Electric, Mt. Whitney Power & Electric Co., California Electric Power Co., Southern California Power Co., and others. SCE was officially incorporated in 1909, through the mergers and acquisitions of these and other small predecessor companies dating back to 1886.
Over the years, SCE has been at the forefront of research and innovation in the energy sector. For example, they have worked on the SOLARII feasibility generator, a solar-powered energy plant capable of producing electricity around the clock by heating molten salts during the day to generate power at night. In 2006, SCE planned to secure 1,500 megawatts or more of power from wind energy projects in the Tehachapi Pass Wind Farm area, significantly expanding its wind energy portfolio. In 2008, the company announced an $875 million project for a network of 250 megawatts of photovoltaic solar power generation, making it the largest solar cell project in the nation at the time.
SCE has also been committed to sustainability and reducing its environmental impact. By 2014, SCE had a renewables mix of 23%, and by 2016, this had increased to 28.2%. The company has also taken steps to improve safety and reduce wildfire risks in California, such as updating its grid with fire-resistant poles and equipment and taking preventative actions through tree trimming and inspections.
