History of the Proceeding

On August 4, 2006, San Diego Gas & Electric Company (SDG&E) filed an application with the Commission for authority to construct the Sunrise Powerlink Transmission Project, a 500 kV transmission line in conjunction with several 230 kV transmission lines. The utility's original application, filed last December, did not include specific details about a proposed route.  The more recent filing does provide detail. 
The project is expected to run 150 miles between the Imperial Valley to San Diego. According to SDG&E, the transmission line would have the capacity to import up to 1,000 megawatts of electricity and would be needed by 2010 to ensure electricity reliability to the area, to reduce energy costs in the area, and to allow SDG&E to meet its obligations to purchase certain amounts of energy from renewable generation resources. SDG&E estimates the cost of the Project to be $1.256 billion.
SDG&E must receive Commission approval for both the purpose and need for the project and the exact route, including a complete investigation of the environmental impacts and possible mitigations, before the project can commence construction. Numerous parties have filed protests to this application, representing local residents and businesses, environmental interests and energy producers.
Parties to the proceeding will have opportunities to present analysis and comments as the Commission considers issues relating to environmental impacts, project economics, and community values. Members of the public who do not plan to be active in the proceeding may share their views on SDG&E's application at any time by sending comments via mail or electronically to our Public Advisor at 505 Van Ness Ave., Room 2103, San Francisco, CA 94102, or
