Edison International is a public utility holding company based in Rosemead, California. Its subsidiaries include Southern California Edison, and un-regulated non-utility business assets Edison Energy. Edison's roots trace back to Holt & Knupps, a company founded in 1886 as a provider of street lights in Visalia, California.


The company was first incorporated in 1909 as Southern California Edison Company after Southern California acquired the assets of Edison Electric Company; it was known as Southern California Edison until 1996 when it adopted its current name in recognition of its growing business abroad and in other industry sectors. Edison first became a holding company in 1988 when it made a small change to its original name, becoming known as SCEcorp.

Edison International became the naming rights holder for the Anaheim Angels' stadium (which was previously known as Anaheim Stadium) in 1998, and was good for 20 years. The company backed out of the naming rights deal after the 2003 season, and the stadium is now called Angel Stadium.

In 2001 Edison's main holding, Southern California Edison faced bankruptcy after a state senate bill regarding financial assistance came up short (by $1 billion).[2]

On August 6, 2002, Edison International recorded core earnings per share of 56 cents in the second quarter of 2002.[3]

Recent moves

In November 2010 Edison sold its 48% interest in the Four Corners coal-fired power plant in New Mexico (units 4 and 5 while units 1,2 and 3 will be closed because of being older) for $294 million to Pinnacle West Capital Corp (of Arizona Public Service). The move was the direct result of a new California law requiring utility companies to exit coal-fired power production (even the renewing of contracts is disallowed), and forces Edison to purchase more power from the market.[4]

San Onofre Nuclear Generating Station Unit 2 shut in early January 2012 for refueling and replacement of the reactor vessel head. Both reactors at San Onofre have been shut since January 2012 due to premature wear found on tubes in massive steam generators installed in 2010 and 2011.

In April 2012, in a sign of mounting concern over the shutdown, the top U.S. nuclear official, Gregory Jaczko, toured the facility with Senator Dianne Feinstein, a Democrat, and U.S. Representative Darrell Issa, a Republican. In June, 2013, the company announced it would permanently shut down operations at the plant, the beginning of a multi-year decommissioning process at the site.

Energy production mix

At least 21% of the fuel Southern California Edison uses to generate power comes from clean energy (half of that nuclear power, the other half renewable energy sources ranging from biomass to wind).[5] The group is a major player in Southern California where it provides 13 million people with electricity.[6]

Southern California Edison began to focus on renewable energy in 1980.
