Sunrise Powerlink energizes the economy

April 19, 2013

The Sunrise Powerlink is a 117-mile, $1.88 billion 500kV electric transmission line from Imperial Valley to San Diego. At the recent regional economic forum Michael R. Niggli, SDG&E President & COO, presented a case study on the Sunrise Powerlink project detailing the economic impact of the project and some of the ways in which the project worked to protect sensitive species during construction. The project was the largest infrastructure project in SDG&E's history. Completed in June 2012, it has already made a tangible difference in system operations and is crucial to alleviating the summer capacity shortages that threaten the area due to the ongoing outage at the San Onofre Nuclear Generating Station.

Economic impact:

  • It's a veritable “renewable energy superhighway” that delivers 1,000 megawatts of power – enough energy for 650,000 homes
  • Generated an astounding $3.2  billion in economic activity and 23,000 jobs for California
  • Injected $1.7 billion into the U.S. economy - $1.1 billion of which was spent in Southern California
  • Catalyst for renewable energy construction; local projects currently under construction generating more than $5 billion in spending and 3,000 jobs

Protecting sensitive species:

  • Created a 13-mile construction free zone for bighorn sheep lambing season from January 1 – June 30
  • Established no-fly zones of more than 4,000-feet around golden eagle nesting sites from December 1 – June 30
  • Relocated hundreds of flat-tailed horned lizards relocated Imperial Valley construction yards and protecting them with specially-designed exclusion fencing
  • Installed special fencing to protect arroyo toads in project locations
  • Preserved in perpetuity more than 11,000 acres of scenic habitat for future generations to enjoy

Sunrise Powerlink enhances reliability, accesses renewable energy and significantly boosts economic development. Businesses are looking for a healthy, reliable power supply.
