That mix includes increased emphasis on energy efficiency, more renewable energy resources, and additional baseload generation plants and transmission capacity. In 2014 SDGE had a
renewables mix of 36.4%, more than the 33% requirement by 2020. By 2016, 43.2% of SDGE's electrical power sources were renewable.
SDGE's system includes 134 distribution substations, 10,558 miles of underground power systems, and 6,527 miles of overhead power systems.

History
Founding
In 1881, power first came to the city of San Diego in the form of gas-lit street lamps. The San Diego Gas Company, a newly formed partnership of eight local businessmen, supplied the gas for the lamps, which were located on Fifth Street in downtown.
The city's first incandescent lighting was provided by a small plant at India and Kalmia Streets. It was installed in 1888 to power the city's first electric streetcar, built that year by the Electric Rapid Transit Street Car Company.
Henry H. Jones, a civil, construction, and electrical engineer, came to San Diego in 1910 as vice president and manager of the San Diego Consolidated Gas & Electric Company and became president shortly thereafter.
[McGrew, Clarence Alan; City of San Diego and San Diego County: The Birthplace of California, Volume 2, pg. 421 (1922).]
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 draftsman and assistant engineer for the Chicago, Peoria, and St. Louis Railroad Company in Springfield, Illinois, then a member of the general engineering staff of the Pennsylvania Railroad at Philadelphia until 1899, when he again went west. Until 1903 he was in Chicago as an assistant engineer of the Chicago & Northwestern Railroad. For seventeen years his work was chiefly confined to traction and electric power engineering. He was general superintendent for the Springfield Railway & Light Company in

, until 1909, and before coming to San Diego was the manager of the Northern Idaho & Montana Power Company. In 1905, the San Diego Gas and Electric Light Company was struggling to meet the demand for its services. The company was sold that year to a Chicago firm H.M. Byllesby & Company and renamed the San Diego Consolidated Gas and Electric Company. Included in the deal were the company's main assets: an electric generating plant with four steam-driven turbines, a gas treatment plant, thirty miles of electric lines, thirty-four miles of gas mains, and the accounts of exactly 3426 customers.
Henry H. Jones, a civil, construction, and electrical engineer, came to San Diego in 1910 as vice president and manager of the San Diego Consolidated Gas & Electric Company and became president shortly thereafter.
By 1920 the company furnished gas and electric service to San Diego city and forty adjacent towns and districts as far north as San Juan Capistrano in Orange County, and south to the Mexican border. When Jones took the management of the company in 1910 it had less than six thousand electric customers and less than nine thousand gas customers, while the number of customers in each branch in 1920 numbered nearly twenty-seven thousand. The quantity measure of service increased in proportion, necessitating the investment of millions of dollars in new equipment and distribution systems. In 1920 the company had five hundred and thirty miles of gas main and over seven hundred miles of electric poll lines.
Mr. Jones served as a director and member of the executive committee during the 1915

In 1940, to comply with federal law, the company ended corporate ownership, made its stock available to the public, and renamed itself San Diego Gas and Electric Company.
SDGE began construction on the
South Bay power plant in 1958, and the first of four oil fuel-burning units came online in 1960. The plant provided much-needed electricity to help the region expand and grow its economy.
SDGE began research into nuclear power in the late 1950s. In 1961, it agreed to participate in a 350,000-kilowatt nuclear power plant with Southern California Edison known as the

border. The plant received a lot of pushback and opposition from California legislators, and the general public had mixed reactions to it. In June 1976, Californians voted to reject Proposition 15, the Nuclear Power Plant Initiative. The ballot measure would have banned the construction of nuclear power plants and limited the use of existing nuclear power plants to 60% (decreasing by 10% annually after five years) and would have reduced the output of California's three existing nuclear reactors and banned new reactors unless the state legislature determined that nuclear safety systems had proven effective and that radioactive waste could be stored safely.

, grew the anti-nuclear discorse. SDGE, which would have built the Sundesert plant, failed to convince the State Assembly Resources Committee that adequate disposal technology was available. Governor
Edmund G. Brown Jr. was largely responsible for Sundesert's defeat. The California State Energy Commission, appointed by the governor, voted 4–1 against the plant. After the state Senate passed a bill exempting the plant from having to dispose of its waste, Brown's allies in the Assembly leadership sent the measure to a committee, where the bill faced an uphill battle. The bill was defeated by a vote of 4 to 7, with three Republicans and one Democrat in favor of the measure and seven Democrats opposed.
Sundesert had consumed an enormous amount of the company's effort for six years and a total of more than $106 million.

TriState was brought on board to abate strips of asbestos-containing pipe coating for another contractor to cut the holder bottle into sections. TriState was later tasked with stripping the coating at the gas holder site despite employee and nearby residents' concerns over friable asbestos generated as a byproduct of the gross stripping processes employed by SDGE contractors.

Charges were dismissed without prejudice in November 2006, but the defendants were re-indicted in early 2007 on nearly identical charges, and the case was heard in San Diego's federal court in June and July 2007. On July 13, 2007, three guilty verdicts were returned against defendants SDGE, IT Corporation project manager Kyle Rhuebottom, and SDGE environmental specialist David "Willie" Williamson, including false statements, failure to provide adequate notice to government agencies of regulated asbestos on the site, and violating asbestos work practice standards to avoid the cost of lawful environmental compliance. SDGE environmental director Jacquelyn McHugh was found not guilty, and defense attorneys vowed to appeal for unjust prosecution.
In late 2007 U.S. District Judge Dana Sabraw ruled that SDGE and the workers deserved a new trial. Criminal charges were dismissed against SDGE on October 6, 2009.

SDGE implemented its system restoration plan and cautioned its customers to expect a prolonged outage. The outage appears to have been caused by the actions of an employee at

Rates
San Diego Gas & Electric consistently ranks among the top U.S. public utility with the highest residential electricity rates. According to the California Public Utilities Commission, the price per kilowatt hour for electricity in California has roughly doubled since 2013.
SDGE's electric rates have increased significantly in recent years, with rates increasing from 28.9 cents per kWh to 47.6 cents per kWh between 2020 and 2024. Concurrently, SDG&E increased rates for customers, San Diego Gas & Electric reported record profits in 2023, making $936 million - a $21 million increase from its 2022 profits of $915 million.
