Southern California Edison (SCE), the largest subsidiary of Edison International, is the primary electric utility company for much of Southern California. It provides 15 million people with electricity across a service territory of approximately 50,000 square miles. [a]
SCE owns all of its electrical transmission facilities and equipment. Deregulation of California's electricity market in the late 1990s forced the company to sell many of its power plants, though some were probably sold by choice. SCE retained its hydroelectric plants, totaling about 1,200 MW, and its 75% share of the 2,150-MW San Onofre Nuclear Generating Station. The plant is being decommissioned. [3]
In addition to its electric business, SCE operates the sole gas utility and water utility on Santa Catalina Island, under the names Catalina Island Gas Company and Catalina Island Water Company.
The origins of the company lie with the grand scheme of business magnate Henry E. Huntington and hydraulic engineer John S. Eastwood, developed around 1908, for a vast complex of reservoirs to be constructed in the Sierra Nevada Mountains of central California. Huntington founded Pacific Light and Power, one of the roughly two dozen companies he controlled at the time, [5] to execute what would eventually become one of the largest hydropower systems in the United States, the Big Creek Hydroelectric Project. Pacific Light and Power 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., [6] and others. [7]
In 2011, a shooting occurred when an employee of Southern California Edison opened fire at an office building in Irwindale.
Southern California Edison allows its customer to obtain their electricity entirely from renewable sources by subscribing to a "green rate". [8]
In 2006, Southern California Edison planned to secure 1,500 megawatts or more of power generated from new projects to be built in the Tehachapi Pass Wind Farm area. The contract, which more than doubles SCE's wind energy portfolio, envisions more than 50 square miles (130 km2) of wind parks in the Tehachapi region, which is triple the size of any existing U.S. wind farm. [9]
In March 2008, Southern California Edison announced a $875 million project to build a network of 250 megawatts of photovoltaic solar power generation, making it the biggest solar cell project in the nation. The photovoltaic cells will cover 65,000,000 square feet (6,000,000 m2) of rooftops in southern California and will generate enough power to serve 162,000 homes. [10]
In 2009, Southern California Edison entered into a contract with Solar Millennium to purchase solar thermal power up to 726 MW. [11] Southern California Edison also entered into a contract with Stirling Energy Systems to buy electricity from a 500 megawatt, 4,600 acre (19 km2), solar power plant which was due to open in 2009. [12] [13] The purchase was canceled in late 2010, as changes in technology reduced the cost of photovoltaic-based solar power to below that of solar Stirling generated power. [14] This would have been the first commercial application of the dish stirling system. A different technology from the more familiar solar panel, the dish concentrates solar energy by the use of reflective surfaces and by the use of the Stirling heat engine to convert the heat into electricity.
In 2014, Southern California Edison installed the Tehachapi Energy Storage Project, which is composed of more than 600,000 lithium-ion battery cells at Monolith Substation in Tehachapi, California in order to test storing power generated from an area that currently has 5,000 wind turbines. [15]
In 2014 SCE had a renewables mix of 23%. [16] By 2016, 28.2% of SCE's power sources were renewable. [17]
In 2017, the company opened two new hybrid electric gas turbine (EGT) units called peaker plants, that combine gas turbines and storage batteries at the same site. Each plant delivers around 50-megawatts; the batteries can provide 10-megawatts and four megawatt-hours of power. Both the turbines and the batteries are designed and manufactured by General Electric’s Power Division. [18]
The plant runs the battery first in a series of short bursts, saving gas usage for longer power demand. The combination of a 30-minute duration battery improves the environmental impact of the gas turbine. The SCE setup (the first of its kind) cut greenhouse gas emissions by 60%, reduced annual water usage by 2 million gallons and lowered the number of gas starts by 50%. [19]
Southern California Edison's power grid is linked to other California ISO resources by the Path 26 transmission lines that generally follow Interstate 5 over Tejon Pass. The interconnection takes place at a large substation at Buttonwillow. CAISO's and WAPA's Path 15 and Path 66, respectively, from Buttonwillow north eventually connect to BPA's grid in the Pacific Northwest. There are several other interconnections with local and out-of-state utilities, such as Path 46.
Southern California Edison has a number of resources and a rate designed specifically for electric vehicle users. [20]
As of July 2018, Southern California Edison planned to add thousands of new charging stations for passenger electric vehicles (EV). This addition is a component of the company's "Charge Ready" program, a pilot program with the aim of increasing the availability of charging ports for EVs.
Since 2016, Southern California Edison has installed 1,000 charging stations throughout their Southern and Central California service area. [21]
The company also runs a rebate program for electric vehicle purchases.
Southern California Edison has a long history of research in the energy arena. Often this includes working with other companies and government entities. One example is the SOLARII feasibility generator, which was a solar-powered energy plant that could produce electricity 24 hours a day. This was done by heating molten salts that would hold the heat during the day and would be used to generate power at night.[ citation needed ]
Dr. John Jurewitz served as Director of Regulatory Policy for Southern California Edison for 15 years until his retirement in July 2007. His major areas of research are in oil, gas, and electricity policy and greenhouse gas regulation. He has testified and participated in government-sponsored proceedings addressing electric industry restructuring and energy policy at the state, federal, and international levels. [22] [23] [24]
In November, 2014, SCE announced a partnership with Ice Energy to provide more efficient energy storage by freezing water at night when electricity is cheaper. [25] (Ice Energy filed for Chapter 7 bankruptcy in December 2019.) [26]
In 2015, Southern California Edison laid off about 400 IT employees, with an additional 100 IT workers leaving voluntarily. [27] Meanwhile, the utility company hired immigrants from India through Infosys, based in Bangalore, and Tata Consultancy Services in Mumbai, which are among the largest users of H-1B visas. [28] [29] SCE was subsequently investigated by the US Department of Labor for potential H1-B visa abuse. [30]
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage, using for example, the pumped-storage method.
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand.

The Tehachapi Pass wind farm is one of the first large-scale wind farms installed in the U.S., with around 710 megawatts (950,000 hp) produced by about 3400 wind turbines.
The San Gorgonio Pass wind farm is a wind farm that stretches from the eastern slope of the San Gorgonio Pass, near Cabazon, to North Palm Springs, on the western end of the Coachella Valley, in Riverside County, California. Flanked by Mount San Gorgonio and the Transverse Ranges to the North, and Mount San Jacinto and the Peninsular Ranges to the South, the San Gorgonio Pass is a transitional zone from a Mediterranean climate west of the pass, to a Desert climate east of the pass. This makes the pass area one of the most consistently windy places in the United States.
Wind power in California had initiative and early development during Governor Jerry Brown's first two terms in the late 1970s and early 1980s. The state's wind power capacity has grown by nearly 350% since 2001, when it was less than 1,700 MW. In 2016, wind energy supplied about 6.9% of California's total electricity needs, or enough to power more than 1.3 million households. Most of California's wind generation is found in the Tehachapi area of Kern County, California, with some large projects in Solano, Contra Costa and Riverside counties as well. California is among the states with the largest amount of installed wind power capacity. In recent years, California has lagged behind other states when it comes to the installation of wind power. It was ranked 4th overall for wind power electrical generation at the end of 2016 behind Texas, Iowa, and Oklahoma. As of 2019, California had 5,973 megawatts (MW) of wind power generating capacity installed.
BrightSource Energy, Inc. is an Oakland, California based, corporation that designs, builds, finances, and operates utility-scale solar power plants. Greentech Media ranked BrightSource as one of the top 10 greentech startups in the world in 2008.
Solar power has been growing rapidly in the U.S. state of California because of high insolation, community support, declining solar costs, and a renewable portfolio standard which requires that 60% of California's electricity come from renewable resources by 2030, with 100% by 2045. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
The Mesquite Solar project is a 512.5-megawatt (MWAC) photovoltaic power plant in Arlington, Maricopa County, Arizona, owned by Sempra Generation and Consolidated Edison Development Inc. The first three phases of the project were constructed using more than 2.1 million crystalline silicon solar panels made by Suntech Power. Mesquite 4 and 5 added another 112.5 MW and 70 MW of battery storage.
Energy is a major area of the economy of California. California is the state with the largest population and the largest economy in the United States. It is second in energy consumption after Texas. As of 2018, per capita consumption was the fourth-lowest in the United States partially because of the mild climate and energy efficiency programs.
California produces more renewable energy than any other state in the United States except Texas. In 2018, California ranked first in the nation as a producer of electricity from solar, geothermal, and biomass resources and fourth in the nation in conventional hydroelectric power generation. As of 2017, over half of the electricity (52.7%) produced was from renewable sources.
The Tehachapi Energy Storage Project (TSP) was a 8MW/32MWh lithium-ion battery-based grid energy storage system at the Monolith Substation of Southern California Edison (SCE) in Tehachapi, California, sufficient to power between 1,600 and 2,400 homes for four hours. At the time of commissioning in 2014, it was the largest lithium-ion battery system operating in North America and one of the largest in the world. TSP is considered to be a modern-day energy storage pioneer with significant accomplishments that have proven the viability of utility-scale energy storage using lithium-ion technology. While originally envisioned as a research and development project, TSP operated as a distribution-level resource for SCE and for calendar year 2020, SCE reported that TSP operated in the wholesale energy market with revenue exceeding operating and maintenance costs. In 2021, SCE began the decommissioning of TSP, which was followed by formal decommissioning by state regulators in 2022. The physical dismantlement of TSP is expected to be completed by the end of 2022.
