El Segundo is a city in Los Angeles County, California, United States. El Segundo, from Spanish, means The Second in English. Located on the Santa Monica Bay, it was incorporated on January 18, 1917, and is one of the Beach Cities of Los Angeles County and part of the South Bay Cities Council of Governments. The population was 16,654 at the 2010 census, up from 16,033 at the 2000 census.

The Douglas Aircraft Company plant in El Segundo was one of the major aircraft manufacturing facilities in California during World War II. It was one of the major producers of SBD Dauntless dive bombers, which achieved fame in the Battle of Midway. The facility, now operated by Northrop Grumman, is still an aircraft plant.

El Segundo has many aviation-related and petroleum-related industries and operations.

Many large aerospace companies have facilities in El Segundo, including Boeing, Raytheon, Lockheed Martin, Northrop Grumman, Wyle Laboratories and The Aerospace Corporation. The last two are headquartered there. It is also home to the Los Angeles Air Force Base and the Space and Missile Systems Center (SMC), which is responsible for space-related acquisition for the military. In addition to the Chevron oil refinery, El Segundo is located next to the Hyperion sewage treatment plant and the El Segundo power plant. The El Segundo power plant is operated by the American energy company NRG. In an effort to combine sustainable and environmentally-friendly techniques with fossil power generation, NRG will create a new combined cycle power island, providing power for 240,000 households. The new power plant, slated to go online in 2013, will use two generators: a Siemens gas turbine and an additional steam turbine. Natural gas will drive the gas turbine, while the hot exhaust gases will generate steam for the steam turbine. The efficiency of the power plant will be increased up to 58%. A huge environmental advantage of this type of power plant is that in combustion, natural gas generates relatively little carbon dioxide compared to other fossil fuels.
