Contruction of Palomar Energy Project Approaches Midway Point

LCG, May 5, 2005--Construction on the Palomar Energy Project, a 550-MW power plant located in Escondido, California, is now about 45 percent complete. The gas-fired plant is expected to be up and running in the summer of 2006.

Palomar Energy LLC, a subsidiary of Sempra Energy Resources, is building the plant. SDG&E, a regulated utility and subsidiary of Sempra Energy, will purchase and operate the plant upon completion.

The natural gas-fired, combined cycle plant includes two combustion turbine-generators equipped with dry low combustors and evaporative inlet air coolers, two heat recovery steam generators equipped with duct burners, a steam turbine-generator and associated auxiliary systems and equipment. The city's sewage treatment plant will supply all of the 3 million gallons per day of reclaimed water used by the generating station. The project includes a new 230 kV switchyard connecting with an existing SDG&E electric transmission line located immediately adjacent to the project site.
