[7] The Sunrise Powerlink includes approximately 117 miles (188 km) of 500-kV and 230-kV overhead and underground transmission lines with several large 230/500-kV substations.

The transmission line linking San Diego to Imperial Valley, one of the most renewable-rich regions in California was put into service on June 18, 2012.

Solar energy from Southern California's Imperial Valley will ultimately be delivered to San Diego through the Sunrise Powerlink transmission lines.

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.

The quantity measure of service increased in proportion, necessitating the investment of millions of dollars in new equipment and distribution systems.

[9] SDGE began construction on the South Bay power plant in 1958, and the first of four oil fuel-burning units came online in 1960.

In the 1970s, SDG&E acquired Mountain Empire Rural Electric Co-op, which served eastern San Diego County.

The plant received a lot of pushback and opposition from California legislators, and the general public had mixed reactions to it.

[15] But coverage of the failed state measure and opposition to a separate nuclear power plant in Kern County, California, grew the anti-nuclear discorse.

[16] SDGE, which would have built the Sundesert plant, failed to convince the State Assembly Resources Committee that adequate disposal technology was available.

It changed ownership at least four times over the past five decades, including Duke Energy, The Unified Port of San Diego, and LS Power.

TriState was brought on board to abate strips of asbestos-containing pipe coating for another contractor to cut the holder bottle into 40-foot (12 m) sections.

Additional defendants included SDGE's director of environmental compliance, an uncertified asbestos removal consultant, and the IT Corporation project manager.

[26] 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.

On September 3, 2008, a jury awarded $55.6 million to the families of four United States Marine aviators killed when their UH-1 helicopter crashed into a 130-foot-tall SDGE utility tower at Camp Pendleton.

[29] During the trial, the plaintiffs argued that SDGE was negligent in its policy of placing warning lights only on towers over 200 feet (61 m) in height.

The company said the power line had been on the base for 25 years and that SDGE would have installed lights if the Marine Corps had asked.

[32] In the wake of the 2020 George Floyd protests and the subsequent attention brought onto topics related to racism and white supremacy, SDGE became the center of national controversy when it fired one of its employees, Emmanuel Cafferty (A Mexican-American), for allegedly displaying the OK gesture, a sign that had recently become associated with the alt-right and white power movement.
