On June 19, 2007, El Segundo Power II, LLC (El Segundo) filed a petition with the California Energy Commission requesting to amend the Energy Commission Decision to eliminate the use of ocean water as the cooling water source for the El Segundo Power Redevelopment Project (ESPR). The petition proposes a new rapid response combined cycle (R2C2) design that will allow the project to operate without once-through cooling, along with changes to the previously approved laydown/staging areas and access routes. The 630 MW ESPR was originally certified by the Energy Commission at a special Business Meeting on December 23, 2004, but a second Business Meeting to consider errata was held on February 2, 2005. The decision, with errata, was certified on February 2, 2005. A petition challenging the certification was filed with the California Supreme Court shortly thereafter, thus delaying the effective date of the decision. With the Court's denial of the petition on August 31, 2005, the decision became final. The facility is located in the City of El Segundo in Los Angeles County.

Description of Proposed Modification

El Segundo has proposed eliminating the use of ocean water as the cooling water source for the project by redesigning the facility to use fast-start turbines and dry-cooling. Additional changes have been proposed to the project, to support this change in design and to address a new laydown area and new equipment delivery options. The following is a list of the proposed changes to the project:

  • Redesign the facility to replace the approved turbines and once-through cooling system with a R2C2 design and dry-cooling, changing the nominal plant capacity from 630 MW to 560 MW;
  • Change the delivery method of oversize equipment to include ocean delivery over the beach and a new land route;
  • Replace the previously approved Fed Ex laydown area (now developed) with a new laydown area at 777 W. 190th Street; and Modify the plant entrance road and gate area to allow the delivery of oversized equipment.

Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
