San Diego Gas & Electric

San Diego Gas & Electric (SDG&E) is the utility that provides natural gas and electricity to San Diego County and southern Orange County in southwestern California, United States. It is owned by Sempra Energy, a Fortune 500 energy services holding company that is based in San Diego.

SDG&E is a regulated public utility that provides energy service to 3.3 million consumers through 1.4 million electric meters and more than 840,000 natural gas meters in San Diego and southern Orange counties. The utility's area spans 4,100 square miles (10,600 square kilometers). SDG&E employs about 5,000 people.

In 2004, the California Public Utilities Commission approved SDG&E's long-term energy resource plan, which relies on a balanced mix of resources to meet the growing energy needs of San Diego. That mix includes increased emphasis on energy efficiency, more renewable energy resources, and additional baseload generation plants and transmission capacity.

Interconnections

SDG&E has two 230 kV lines (Miguel-Tijuana line and the LaRosita-Imperial Valley Line) that connect the Californian transmission system with the Mexican Comisión Federal de Electricidad transmission system in Baja California. The Path 45 transmission corridor, spanning over the United States-Mexico border, has a capacity of 408 Megawatts. SDG&E has a 500 kV line connecting to Arizona Public Service. There is also a 230 kV line connecting to Imperial Irrigation District. Both of these are part of the massive Path 46 transmission system ensuring Southern California has adequate energy.
