San Diego Gas & amp; Electricity (SDG & E ) provides natural gas and electricity to San Diego County and southern Orange County in southwestern California, USA. The company is owned by Sempra Energy, San Diego's state-owned energy services company Fortune 500.
SDG & amp; E is a regulated public utility that delivers energy services to 3.3 million consumers through 1.4 million meters of electricity and over 840,000 meters of natural gas in San Diego and the southern Orange district. This utility area covers 4,100 square miles (10,600 square kilometers). SDG & amp; E employs about 5,000 people.

In 2004, the California Public Utilities Commission approved the SDG's long-term energy resource plan & amp; E, which relies on a balanced mix of resources to meet the growing energy needs of San Diego. The mix includes increased emphasis on energy efficiency, renewable energy resources, and additional base load generation and transmission capacity. In 2014, SDG & E has 36.4% renewable energy mix, more than 33% requirement in 2020. By 2016, 43.2% of SDG & amp; E renewable.

Interconnection
SDG & amp; E has two 230 kV lines (the Miguel-Tijuana and LaRosita-Imperial Valley Line lines) that connect the California transmission system with the Federal ComisÃÆ'³n Federal de Electricidad transmission system in Baja California. The Path 45 transmission line, which extends over the US-Mexican border, has a capacity of 408 Megawatts. SDG & amp; E has 500 kV channels connected to Arizona Public Service. There is also a 230 kV line connecting to the Imperial Irrigation District. Both are part of a massive Path 46 transmission system that ensures Southern California has sufficient energy.
The 117-mile Sunlink Powerlink, 500,000-volt transmission line connects San Diego to the Imperial Valley, one of California's most renewable-rich areas that began operations on June 18, 2012.
Initial history
Henry H. Jones , civil, construction and electrical engineer, came to San Diego in 1910 as vice president and manager of San Diego Consolidated Gas & Electric Company, and became president shortly thereafter.
Henry Harrison Jones was born in Reading, Pennsylvania, March 31, 1874, son of Richard Hall and Ellen (Hughes) Jones. After graduating from high school in 1890, he was a bookkeeper at the Second National Bank, then entered Lehigh University to pursue a technical course. He graduated as a Civil Engineer in 1897, then for a year was a photographer and assistant engineer for Chicago, Peoria and St. Louis Railroad Company in Springfield, Illinois, then a member of the general engineering staff from the Pennsylvania Railroad in Philadelphia until 1899, when he again went to west. Until 1903 he was in Chicago as an assistant engineer for Chicago & amp; Northwest Railway. For seventeen years his work was mainly limited to traction and electrical engineering. He is the general inspector for Springfield Railway & amp; Light Company in Springfield, Illinois, until 1909, and before coming to San Diego was Northern Idaho & Montana Electric Company. In 1910, he received the post of vice president and manager of San Diego Consolidated Gas & Electricity company.
In 1920 the company provided gas and electricity services to the city of San Diego and forty cities and adjacent districts, as far north as San Juan Capistrano in Orange County, and south to the Mexican border. When Jones took over the management of the company in 1910, he had less than six thousand electric customers and less than nine thousand gas customers, while the number of subscribers in each branch in 1920 amounted to nearly twenty-seven thousand. The size of the service quantity increases proportionately, thus requiring a multimillion dollar investment in new equipment and distribution systems. The company in 1920 had five hundred and thirty miles of main gas and over seven hundred miles of electric voting lanes.
Mr Jones served as a director and member of the executive committee during the Panama-California Expo (1915), whose group was responsible for designing, constructing and building the first original structures and buildings in Balboa Park, San Diego, California.
United States versus San Diego Gas & amp; Electricity
The Encanto Gas Holder is a natural gas holding station composed of more than 9 miles (14 km) from a 30-inch (760 mm) underground pipe at about 16 acres (65,000 m 2 ) land in Lemon Grove, adjacent to the city of San Diego. First brought online in the mid-1950s, Encanto Gas Holders was disabled in 2000-2001 by San Diego Gas and Electric, Sempra Energy as an SDG & amp; E, and IT Corporation as the main contractor for decommissioning. TriState is brought to the board to tear the strip from the pipe layer containing asbestos to another contractor to cut the holder bottle into a 40-foot (12 m) section. TriState is then tasked with stripping the coating on the gas holder site even though the employees and the nearby residents' concerns over friable asbestos are produced as a by-product of the gross stripping process carried out by the SDG & E contractors.
In 2006, SDG & amp; E was indicted by US Attorney Carol C. Lam in the Southern District of California on five counts, including conspiracy, fraud, and three false allegations of handling asbestos-containing material in violation of the National Emissions Standards for Hazardous Water. Pollutant. Other defendants include SDG & Environmental Compliance Director E, unlicensed asbestos removal consultant, and IT Company project manager. The charges were dismissed without prejudice in November 2006, but the defendants were again indicted in early 2007 on nearly similar charges, and the case was heard in San Diego federal court in June and July 2007. On July 13, 2007, three of the guilty verdicts were reinstated against defendant SDG & amp; E, IT Corporation project manager Kyle Rhuebottom, and environmental specialist SDG & amp; E David "Willie" Williamson, including a misstatement, failure to provide adequate notice to government agencies about regulated asbestos on the site, and violates standard asbestos work practices to avoid legitimate environmental compliance costs. Director of SDG & amp; E Jacquelyn McHugh was found not guilty, and defense lawyers vowed to appeal an unjust prosecution.
At the end of 2007, US District Judge Dana Sabraw decided that the SDG & amp; E and workers are entitled to a new trial. Criminal allegations dismissed against SDG & amp; E on October 6, 2009.
Sea helicopter crash demands
On September 3, 2008, a jury awarded $ 55.6 million to the families of four US marine airmen killed when their UH-1 helicopter crashed into a 130-foot SDG & amperes tower at Camp Pendleton. The given amount includes $ 15.2 million in compensation compensation and $ 40.4 million in damages. The jury holds SDG & amp; E which is responsible for $ 9.48 million of compensation amount and all punitive damages.
During the trial, the plaintiffs argued that SDG & amp; E negligent in its policy of placing warning lights only on towers that are over 200 feet (61 m) tall. The company said that the power grid has been on base for 25 years and that SDG & E will install lights if the Marine Corps asks. Since the accident, the company has installed the lights, says Todd Macaluso, a family lawyer. SDG & amp; E said that it would appeal the verdict.
Power outage area of ​​districts 2011
On September 8, 2011, at 3:38 PM Pacific Standard Time, major power outages left 1.4 million SDG & amp; E without electricity. The problem begins with an error at an Arizona Public Service base near Yuma, Arizona that causes widespread problems in western Arizona and eastern California. In time, the SDG & amp; E was withdrawn from San Onofre Nuclear Generating Station (SONGS) with much greater power than the one produced, withdrawing it from Los Angeles, and the "safety net" system cutting it off from a nuclear plant. Once this happens, the SDG & amp; E quickly collapsed due to mismatch of generation and load, can not lower the load faster than the lost generation. SDG & E implemented their system recovery plan and warned their customers to expect extended blackouts. The blackout was apparently due to the actions of an employee at the Gila North substation in Arizona, and it is unknown why the protection did not make the blackout confined to the Yuma area.
On Friday morning at 9, power had been restored to all 1.4 million customers SDG & amp; E.
