STATE OF CALIFORNIA THE RESOURCES AGENCY ARNOLD SCHWARZENEGGER, Governor CALIFORNIA ENERGY COMMISSION 1516 NINTH STREET SACRAMENTO, CA 95814-5512 DATE: June 8, 2005 TO: Interested Parties FROM: Connie Bruins, Compliance Project Manager SUBJECT: Inland Empire Energy Center Power Project (01-AFC-17C) Staff Analysis Of Proposed Modifications To Change To GE 107H Combined-Cycle Systems, Increase Generation and Add Additional Laydown Areas On March 11, 2005, the California Energy Commission received a petition from Inland Empire Energy Center, LLC, (IEEC) to amend the Energy Commission Decision for the Inland Empire Energy Center Power Project. The 670-megawatt project was certified by the Energy Commission on December 17, 2003, and is expected to begin construction in the summer of 2005. The facility will be located on approximately 45.8 acres near the community of Romoland in unincorporated Riverside County. IEEC requests to change the previously-approved power generation configuration that consists of two GE Frame 7F combustion turbine-generators. The proposed new configuration would consist of two GE 107H combined-cycle systems (H System). The H System represents GE’s latest gas turbine technology providing superior fuel economy and environmental performance. This proposed modification would require changes to the site layout concerning location of structures and add approximately four acres to the fenced area of the project site. In addition, IEEC requests to add two temporary areas near the project site for construction worker parking and secondary laydown. The additional 11.5 acres will allow for a more efficient use of the project site during construction and safer, more cost-effective construction staging. Energy Commission staff reviewed the petition and assessed the impacts of this proposal on environmental quality, public health and safety. • Staff determined that no changes to conditions of certification are required for the technical areas of efficiency, geology, mineral resources and paleontology, reliability, traffic and transportation, and transmission line safety and nuisance. • Staff prepared new and/or made revisions to existing conditions of certification for air quality, biology, facility design, hazardous materials, noise, reliability, soil and water resources, transmission system engineering, and worker safety and fire protection. It is staff’s opinion that with the implementation of revised conditions for these technical areas, the project will remain in compliance with applicable laws, ordinances, regulations, and standards and that the proposed modifications will not result in a significant adverse direct or cumulative impact to the environment (Title 20, California Code of Regulations, Section 1769). The amendment petition and staff’s analyses have been posted on the Energy Commission’s webpage at energy.ca.gov/sitingcases/inlandempire/index.html. Staff’s analyses are enclosed for your information and review. The order will also be posted on the webpage if the amendment is approved. Energy Commission staff intends to recommend approval of the petition at the June 22, 2005 Business Meeting of the Energy Commission. If you have comments on this proposed modification, please submit them to me at the address below prior to June 22, 2005: Connie Bruins Compliance Project Manager California Energy Commission 1516 9th Street, MS 2000 Sacramento, CA 95814 Comments may be submitted by fax to (916) 654-3882, or by e-mail to [email protected]. If you have any questions, please contact Connie Bruins, Compliance Project Manager, at (916) 654-4545.

The 670-megawatt project was certified by the Energy Commission on December 17, 2003, and is expected to begin construction in the summer of 2005. The facility will be located near the community of Romoland, in Riverside County. The Inland Empire Energy Project was certified using the most modern, fuel efficient gas-fired generating technology then commercially available, the GE Frame 7F gas turbine generator in a combined-cycle configuration. In recent years, GE has pursued development of the H-technology gas turbine. The first H machine, a 50 Hz Frame 9H unit rated at 480 MW, was installed at Baglan Bay, Wales, and began operational testing in November 2002. The first 60 Hz Frame 7H machine was ordered by Sithe Energies for installation at the Heritage Power Station in Scriba, NY, but the order was subsequently cancelled due to unfavorable economic conditions. GE proposes to install, operate and test this initial Frame 7H machine. In order to pursue this essential step in the development and marketing of this new product, GE has completed an agreement with Calpine to install the first Frame 7H machine, along with a second machine, at the IEEC. Substituting these two larger capacity machines for the Frame 7F machines initially certified necessitates this amendment. PROPOSED AMENDMENT IEEC requests to change the previously-approved power generation configuration that consists of two GE Frame 7F combustion turbine-generators. The proposed new confirguration would consist of two GE 107H combined-cycle systems (H System). The H System represents GE’s latest gas turbine technology providing superior fuel economy and environmental performance. This proposed modification would require changes to the site layout concerning location of structures and add approximately four acres to the fenced area of the project site. In addition, IEEC requests to add two additional temporary areas for construction worker parking and secondary laydown. The additional 11.5 acres will allow for a more efficient use of the project site during construction and safer, more cost-effective construction staging. Key revisions to the site layout are proposed as follows: • The combustion turbines (CT) and steam turbines (ST) will share common shaft lines, and will be pedestal mounted at the ST elevation. Summary iii Inland Empire Amendment June 2005 • Each of the two STs will have a dedicated 8-cell cooling tower. These two towers will replace the previously-approved single 14-cell cooling tower. • The entire facility will be moved approximately 80 feet to the south (within the same site boundaries). • A chiller and space for a future thermal storage tank will be added and located in the area between the two heat recovery steam generators (HRSGs). This system will provide chilled water for cooling of the CT inlet air, replacing the fogging systems used in the previous configuration. • Onsite gas compressors with fin-fan coolers and condensate storage tanks will be added. • A second standby generator will be added such that each CT/ST/HRSG train will have a dedicated standby generator. • The
