Southern California Edison (SCE) stands as the largest subsidiary of Edison International and functions as the main electric utility provider for a significant portion of Southern California. It delivers electrical power to an estimated 15 million residents spread over an area close to 50,000 square miles.

SCE maintains ownership of its entire electric power transmission network. After California's electricity market underwent deregulation in the late 1990s, SCE divested many of its power generation facilities, choosing to keep its hydroelectric plants with a combined capacity near 1,200 MW, as well as holding a 75% ownership interest in the 2,150-MW San Onofre Nuclear Generating Station. This nuclear plant ceased operations in 2012 and is currently in the process of being dismantled.

In addition to electricity services, SCE manages the exclusive natural gas and water utilities on Santa Catalina Island via its subsidiaries Catalina Island Gas Company and Catalina Island Water Company.

History

The origins of the company date back to around 1908, when entrepreneur Henry E. Huntington and engineer John S. Eastwood played pivotal roles. Huntington established Pacific Light and Power with the goal of developing the Big Creek Hydroelectric Project, which became one of the largest hydropower systems in the United States. Pacific Light and Power was among several entities that eventually merged or evolved into Southern California Edison (SCE), alongside companies such as Edison Electric, Mt. Whitney Power & Electric Co., California Electric Power Co., and Southern California Power Co.

In 2011, an unfortunate event occurred when an employee at an SCE facility in Irwindale opened fire inside the office building.

Renewable energy

Southern California Edison provides customers with an option to purchase electricity entirely generated from renewable sources through a specialized "green rate" program.

In 2006, SCE committed to acquiring more than 1,500 megawatts from new wind energy projects located within the Tehachapi Pass Wind Farm region. This initiative significantly expanded its wind energy portfolio, planning to develop wind farms spanning over 50 square miles—making it three times larger than any existing wind farm in the United States at that time.

By March 2008, SCE had launched a solar program worth $875 million aimed at installing 250 megawatts of photovoltaic capacity across approximately 65 million square feet of rooftops throughout Southern California. This effort was designed to supply clean energy to nearly 162,000 households.

In 2009, SCE entered agreements with Solar Millennium for up to 726 MW of solar thermal power generation and with Stirling Energy Systems for a proposed 500 MW solar facility utilizing dish Stirling technology. However, the latter project was discontinued in 2010 due to decreasing costs associated with photovoltaic technology.

In 2014, SCE implemented the Tehachapi Energy Storage Project—a large-scale lithium-ion battery installation at Monolith Substation—to improve storage capabilities for wind power generated from a region hosting approximately 5,000 turbines.

The proportion of renewable energy within SCE’s overall energy portfolio increased from 23% in 2014 to 28.2% by 2016, underscoring its strategic focus on integrating clean energy sources.

Natural gas and energy storage

In 2017, the company introduced two hybrid electric gas turbine (EGT) peaker facilities that integrate gas turbines with battery storage systems. Each facility generates roughly 50 megawatts, with battery capacity contributing 10 megawatts and four megawatt-hours of energy storage. Both the turbines and batteries are produced by General Electric’s Power Division.

These plants are designed to utilize battery power for brief intervals, reserving natural gas usage for extended demand periods. The batteries provide a 30-minute discharge capacity, which significantly improves environmental outcomes by cutting greenhouse gas emissions by 60%, reducing annual water consumption by 2 million gallons, and decreasing the frequency of gas turbine startups by half. This pioneering configuration offers a strategic edge in delivering cleaner energy alternatives.

Interconnections

Southern California Edison’s electrical grid is linked to California ISO resources through the Path 26 transmission corridor near Tejon Pass, connecting at the Buttonwillow substation. From this point, CAISO’s Path 15 and WAPA’s Path 66 extend northward to integrate with the Bonneville Power Administration network in the Pacific Northwest. The company’s extensive regional system also includes interconnections with local and out-of-state utilities such as Path 46, enhancing operational flexibility and grid resilience.

Electric vehicles

As part of its commitment to sustainable transportation, Southern California Edison provides tailored programs and rate structures specifically designed for electric vehicle (EV) users.

By mid-2018, the company intended to significantly broaden its EV charging network through the "Charge Ready" pilot initiative, targeting an increase in available charging ports. Since 2016, SCE has deployed approximately 1,000 charging stations throughout Southern and Central California, reinforcing its leadership role in supporting EV adoption.

Moreover, SCE administers a rebate program for electric vehicle purchases that aligns with its environmental objectives while promoting customer participation in evolving energy markets.

Energy research and policy

Southern California Edison maintains an active role in energy innovation through partnerships with corporations and government agencies. One notable project was the SOLARII feasibility generator, a solar-powered facility capable of continuous electricity generation by storing thermal energy in molten salts.

Dr. John Jurewitz served as Director of Regulatory Policy for fifteen years until 2007, concentrating on regulatory matters related to oil, gas, electricity, and greenhouse gas controls. He contributed to numerous governmental deliberations concerning electric industry restructuring and broader energy policies at various jurisdictional levels.

In 2014, SCE collaborated with Ice Energy to enhance energy storage techniques by freezing water overnight during off-peak electricity pricing periods. (Ice Energy subsequently filed for Chapter 7 bankruptcy in 2019.)

Labor practice controversy

In 2015, Southern California Edison terminated approximately 400 IT staff members while simultaneously hiring workers from India via Infosys and Tata Consultancy Services—two prominent users of H-1B visas. This action provoked employee dissatisfaction and prompted an investigation by the U.S. Department of Labor into possible misuse of H-1B visa regulations.

Disasters and Litigation

Wildfires remain an ongoing concern in California, with several significant events traced back to equipment owned or operated by Southern California Edison.

Liability

Under California’s inverse condemnation statute, utilities are held responsible for wildfire damages caused by their electrical infrastructure, irrespective of fault or negligence. In July 2019, the state created a $21 billion wildfire trust fund designed to address future wildfire claims, with funding equally shared between utility customers and shareholders. This legislation also altered the legal standard by requiring plaintiffs to demonstrate utility negligence—not merely the involvement of utility equipment—to recover damages from utilities, subject to a maximum limit.

1996 Calabasas Fire

In October 1996, the Calabasas Fire consumed 13,010 acres and destroyed six buildings near Pepperdine University. During the ensuing inquiry, Edison withheld critical documents from Cal Fire, prompting covert efforts to secure floor plans of Edison’s facilities. Investigators ultimately determined that Edison’s equipment was responsible for igniting the fire. Despite Edison’s inadequate tree maintenance near power lines and evidence tampering during the probe, the Los Angeles County District Attorney found no criminal wrongdoing. Following this, Edison collaborated with government agencies to establish protocols for future wildfire investigations.

Creek Fire (2017)

The Creek Fire raged through Los Angeles from December 5, 2017, until January 9, 2018, resulting in the destruction of 123 structures. Early examinations focused on the Los Angeles Department of Water and Power (LADWP), which led to lawsuits filed by over 300 victims as well as federal authorities. However, during legal proceedings, it emerged that Southern California Edison (SCE) had withheld data from December 5—the day the fire began. Subsequent evidence revealed an electrical malfunction in SCE’s equipment at that time. A federal investigator concluded that SCE caused the blaze, prompting a federal lawsuit accusing SCE of both causing the fire and suppressing evidence. The government further alleges that SCE breached a prior agreement and wrongfully implicated LADWP. SCE denies these claims, attributing the missing data to an employee mistake.

Thomas Fire

The Thomas Fire ignited in December 2017 and merged with the Koenigstein Fire on its first day, affecting Ventura and Santa Barbara counties until January 2018. It destroyed over 1,000 buildings and resulted in two fatalities. Additionally, mudslides in Montecito triggered by the fire caused 23 more deaths and extensive property damage. Official investigations linked both fires to failures in SCE’s equipment. Edison resolved related lawsuits with settlements exceeding $2.7 billion.

On January 30, 2025, the California Public Utilities Commission (CPUC) authorized SCE’s rate increase request to recoup $1.6 billion paid to Thomas Fire claimants. This ruling met resistance from Los Angeles residents and seven state legislators who contended that customers should not be burdened with costs stemming from Edison’s errors and argued it weakens accountability measures. Edison maintained it was not negligent and intends to amortize these costs over three decades to mitigate financial strain on consumers.

Woolsey Fire

The Woolsey Fire swept through Los Angeles and Ventura counties in November 2018, destroying 1,643 structures and causing three deaths. In 2020, the California Public Utilities Commission (CPUC) determined that Edison’s electrical equipment was responsible for igniting the fire, resulting in a $2.2 billion settlement paid by Edison.

The California Department of Justice investigated potential criminal charges against Southern California Edison (SCE) but opted not to prosecute after concluding that although SCE’s equipment and vegetation management practices contributed to the fire, their actions did not meet criminal culpability standards. Following this decision, SCE emphasized its ongoing commitment to reducing wildfire risks; however, attorneys representing victims expressed dissatisfaction with the outcome.

Shortly before this announcement, California Attorney General Rob Bonta received a $72,500 contribution from SCE, which was subsequently returned amid controversy concerning its timing. This event drew media scrutiny regarding corporate influence and regulatory oversight related to wildfire liabilities.

Eaton Fire

In January 2025, a significant wildfire erupted in the Eaton Canyon region of the San Gabriel Mountains, extending into nearby foothill neighborhoods such as Altadena. This devastating blaze caused 18 deaths and destroyed more than 9,000 structures, making it the second most damaging wildfire in California's history.

Investigations traced the fire’s origin to Southern California Edison (SCE) transmission lines located in Eaton Canyon. At the time the fire ignited, SCE reported a malfunction on their equipment. Prior regulatory assessments had criticized Edison for inadequate inspections of high-risk transmission infrastructure and for failing to detect potential dangers during these evaluations. Furthermore, regulators highlighted that Edison’s wind speed monitoring intervals—set at ten minutes—were insufficient compared to competitors who monitored every thirty seconds.

Edison stressed its continuous efforts to mitigate wildfire risks and urged caution against drawing early conclusions. The company suggested that a nearby homeless encampment might have played a role in starting the fire but maintained that it acted responsibly, even if held accountable.

Legal proceedings quickly ensued: on January 13, four lawsuits accused SCE of breaching safety regulations and negligence regarding power shut-offs. Additional wrongful death claims and lawsuits from local authorities, including Los Angeles County and Pasadena, alleged that Edison failed to deactivate power lines during red flag warnings amid Santa Ana wind conditions.

During the incident, NPR reported that Edison restored power lines despite firefighter requests to keep them de-energized; this action reportedly led to downed lines igniting further fires. Attorneys representing victims also accused Edison of interfering with evidence by prematurely reactivating suspect lines. Edison defended these actions as necessary steps to restore electricity to customers.

Additional Wildfire Incidents

Numerous major wildfires have been associated with equipment owned by Edison, such as the 2007 Malibu Canyon Fire, the 2017 Liberty Fire, along with the Meyers Fire, Rye Fire, and Easy Fire, which collectively consumed 1,860 acres in Ventura County. Other notable fires include the 2020 Bobcat Fire, Silverado Fire, the 2022 Coastal Fire, and the Fairview Fire. There are also potential links to the Hurst Fire and Palisades Fire. These fire events have led to considerable financial liabilities and settlements for Southern California Edison, affecting its economic outcomes and highlighting the critical need for enhanced risk mitigation and infrastructure investment policies.
