SCE is transitioning to clean energy, with a focus on wind and solar power
Southern California Edison (SCE) is one of the nation's largest electric utilities, delivering power to 15 million people across 50,000 square miles in central, coastal, and southern California. SCE is committed to leading the transition to clean energy and has made significant investments in wind and solar power to support this goal.
SCE has recognized the importance of renewable energy sources and has taken steps to integrate them into its power generation portfolio. In 2011, the company delivered approximately 15.5 billion kilowatt-hours of renewable power, accounting for 21.1% of its total electricity delivery that year, which was more than any other U.S. utility. This included power generated from wind farms and solar plants, as well as hydroelectricity from the Big Creek Hydroelectric Project in the Sierra Nevada Mountains.
To deliver wind power to its customers, SCE has invested in strategic infrastructure projects like the Tehachapi Renewable Transmission Project, which is the nation's largest wind energy delivery infrastructure. This project involves harnessing wind energy from an area with 5,000 wind turbines and storing it using lithium-ion battery cells at the Monolith Substation in Tehachapi, California.
In addition to wind energy, SCE has made significant strides in solar power generation. The company's Rooftop Solar Program is the nation's largest advanced solar photovoltaic project, generating clean and renewable energy by installing solar panels on the roofs of existing warehouses in sunny, inland areas. This innovative program puts otherwise unused rooftops to good use and is designed to produce up to 220 megawatts of solar power. SCE has also connected 547 megawatts of solar energy to the grid, which has had a significant environmental impact, equivalent to removing hundreds of thousands of cars from the road for a year.
SCE offers its customers the opportunity to support renewable energy through its Green Rate program. This voluntary program allows customers to purchase energy from renewable sources, primarily solar power, without having to install and maintain their own solar panels. Customers can choose between two options: using 50% or 100% of their energy usage to fund solar energy sources, with corresponding credits applied to their bills.
By transitioning to clean energy, with a focus on wind and solar power, SCE is not just meeting the immediate energy needs of its customers but also contributing to California's goal of becoming net-zero by 2045. The company's efforts in expanding renewable energy sources, improving infrastructure, and offering customer-centric programs demonstrate its commitment to a sustainable future.

SCE's history includes the Big Creek Hydroelectric Project and wildfires caused by its equipment
The logo of Southern California Edison (SCE) features a stylized sun motif. The company is one of the nation's largest electric utilities, delivering power to 15 million people across 50,000 square miles in Southern California. SCE's history is closely tied to two significant events: the Big Creek Hydroelectric Project and wildfires caused by its equipment.
The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River in the Sierra Nevada of central California. The project, originally envisioned by hydraulic engineer John S. Eastwood, was developed around 1908 by business magnate Henry E. Huntington's company, Pacific Light and Power (PL&P). PL&P merged with SCE in 1917, and the Big Creek Project became part of SCE's operations.
The project has expanded over the years and now includes 27 dams, miles of tunnels, and 24 generating units in nine powerhouses, with a total capacity of over 1,000 megawatts. The Big Creek Project generates about 90% of SCE's hydroelectric power and accounts for 12% of all hydroelectric power produced in California.
However, SCE's history also includes wildfires caused by its equipment. Wildfires are an ongoing issue in California, and several major wildfires have been linked to SCE's electrical infrastructure. The Thomas Fire in 2017, for instance, resulted in SCE seeking permission from the state's Public Utilities Commission to pass on more than $1 billion in liability costs to ratepayers. More recently, in 2025, the Hurst Fire burned approximately 799 acres, and investigations suggest a possible link to SCE's equipment. SCE has submitted reports and is cooperating with authorities to determine the cause.
SCE has a long history of research and innovation in the energy sector. They have implemented programs like "Charge Ready" to support electric vehicle adoption and are committed to sustainability and California's goal of becoming net-zero by 2045. Despite these efforts, the company must balance its operations with the environmental and social impacts of its projects, such as those experienced with the Big Creek Hydroelectric Project.
