Major Power Line Outage Forces Southern California Transmission Emergency.FOLSOM, Calif. -- The loss of a major western transmission line just as California power use was approaching its peak today forced the California ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. to issue a Transmission Emergency notice for Southern California Southern California, also colloquially known as SoCal, is the southern portion of the U.S. state of California. Centered on the cities of Los Angeles and San Diego, Southern California is home to nearly 24 million people and is the nation's second most populated region, only, and to request utilities in the Southland south·land or South·land n. A region in the south of a country or an area. south  land·er n.Noun 1. to reduce demand on the system by dropping 900 megawatts of firm load and 800 megawatts of voluntary, interruptible customers. California ISO ordered restoration of firm load (involuntary customers) at 4:35 p.m. The Pacific DC Intertie The Pacific DC Intertie (also called Path 65) is an electric power transmission line which transmits electricity from the Pacific Northwest to the Los Angeles area using high voltage direct current (HVDC). (PDCI), a 500-thousand volt transmission line that runs between Southern Oregon This article is about the southern region of the U.S. state of Oregon. For the University, see Southern Oregon University. Southern Oregon is a region of the U.S. and Southern California, suddenly and unexpectedly dropped out of service just before 4:00 p.m. today. The loss of more than 2,800 megawatts of power coming into Southern California coupled with the area's high demand required a reduction in system load to keep the grid in balance. Loads in southern California were running about 2,000 megawatts higher than anticipated due to temperatures that were up to 14 degrees higher than forecast. No details are available yet about what caused the PDCI to trip off line. The California ISO is charged with managing the flow of electricity along the long-distance, high voltage The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to power lines that make up the bulk of California's transmission system. The not-for-profit public-benefit corporation assumed the responsibility in March, 1998, when California opened its energy markets to competition and the state's investor-owned utilities turned their private transmission power lines over to the California ISO to manage. The mission of the California ISO is to safeguard the reliable delivery of electricity, facilitate markets and ensure equal access to a 12,500 circuit mile "electron highway." |
