EDISON INTERNATIONAL

Overview

Edison International is a U.S. energy holding company whose principal business is Southern California Edison (SCE), an investor-owned electric utility that supplies and delivers electricity across Southern, Central and Coastal California. The company also owns Trio, a global energy-advisory business serving commercial, industrial and institutional customers with energy and sustainability solutions. SCE serves more than 15 million people across an approximately 50,000-square-mile territory; its utility operations are California-based, while Trio’s advisory business is global.[1][2]

Edison International’s stated vision is to lead the electric-power industry’s transformation toward a clean-energy future. In 2025, it reported $19.317 billion in operating revenue and 13,725 employees; SCE had 5.389 million customer accounts at year-end.[2]+3 [1]+4

Products & services

Edison International’s principal customer-facing products and services are provided through Southern California Edison (SCE), its electric utility subsidiary. SCE supplies and delivers electricity and operates the transmission and distribution infrastructure serving customers across Southern, Central and Coastal California. Residential service includes tiered and time-of-use rate options, with prices varying by usage tier and, for time-of-use plans, by time and season.[6][7] SCE also offers a Solar Billing Plan that credits eligible customers for surplus electricity exported from their solar systems, with credit values varying according to when the electricity is exported.[8]

SCE’s electrification offerings include Charge Ready programs supporting light-duty vehicle charging and medium- and heavy-duty fleet electrification. At year-end 2025, construction was underway at 572 light-duty program sites supporting 9,761 charge ports, and at 132 Charge Ready Transport sites supporting electrification of 2,859 medium- and heavy-duty vehicles.[9] SCE also provides business energy-efficiency incentives or financing for upgrades including HVAC and cooling, refrigeration, lighting and controls.[10][11] Edison International completed the sale of its energy-advisory subsidiary Trio in the second quarter of 2026, so it is not included here as a current offering.[12] The available reporting does not disclose product- or service-level shares of company performance.[6] [6]+6

Geographic presence

Southern California Edison (SCE), Edison International’s electric utility, serves customers across approximately 50,000 square miles of Southern, Central and Coastal California, covering portions of 15 counties and serving about 15 million people. Its reported utility footprint is in California; no electricity sales footprint outside the state is identified.[1][13] Edison International and SCE list their principal executive offices in Rosemead, California.[14]

Edison International’s subsidiary Trio provides energy advisory services globally. Its listed offices include locations in California, Massachusetts and New Jersey, as well as the UK, Bosnia and Herzegovina, the Netherlands and Germany; these advisory locations are distinct from SCE’s electricity service territory.[1][15] The available sources do not provide revenue percentages by geography or an employee breakdown by location.[1][4] [1]+4

Business segments

Edison International reports **Southern California Edison (SCE)** and **Edison International Parent and Other** in its segment-results presentation. SCE is the regulated electric utility serving Southern and Central California [16]. Parent and Other covers parent-company activities and other businesses; the 2026 results include losses related to the disposition of Trio, its energy-advisory and sustainability business [17][16].

By **net income (loss) available to Edison International**, SCE contributed approximately **118.5%** of the consolidated total in the first half of 2026 ($1,262 million of $1,065 million), while Parent and Other contributed approximately **(18.5%)** (a $197 million loss). SCE’s share exceeds 100% because Parent and Other reported a loss [18]. For full-year 2025, the corresponding shares were approximately **109.6%** for SCE ($4,889 million of $4,459 million) and **(9.6%)** for Parent and Other (a $430 million loss) [19]. These percentages represent earnings contributions, not revenue shares. [17]+7

Company history

Edison International traces its origins to July 4, 1886, when a predecessor utility used a steam engine to provide electric lighting in Visalia, California. The predecessor companies grew and consolidated in the region; Southern California Edison (SCE) identifies 1901 as its establishment date, while its corporate profile dates its incorporation to 1909.[20][13] A major early expansion came with the Big Creek hydroelectric project, which began delivering power in 1913 and was acquired by SCE in 1917.[21]

Edison International was incorporated in 1987 as the holding-company parent of SCE. During 1989–1996, SCEcorp was renamed Edison International as the company expanded into international energy businesses, including through Edison Mission Energy.[22][23] Edison Mission Energy entered bankruptcy in 2012, and its reorganization and sale of substantially all assets to NRG were completed in 2014.[24][25]

In 2013, SCE announced the permanent retirement of the San Onofre nuclear generating station’s Units 2 and 3, ending more than 40 years of operation.[26] Edison International launched Edison Energy in 2016 to provide energy-related services to large customers, and sold SoCore Energy in 2018.[27][28] [20]+9
