San Diego Gas and Electric
San Diego Gas & Energy, a Sempra Energy subsidiary, is a regulated public utility that employs about 5,000 people who work to bring energy to 3.4 million customers in San Diego and southern Orange Counties. SDG&E can trace its roots to five San Diegans who met in 1881 to form the San Diego Gas company. At that time, they facilitated the purchase of 15 street lamps. That number exceeds 99,000, today.
