PLANT SITE INFORMATION FOR KEMPER COUNTY MISSISSIPPI This doctnnent contains a description of a plant site in Kemper County, Mississippi, information on Mississippi Power Company (MPO) and the impacts of executing the project under Cooperative Agreement at that site. The plant at the Kemper County site will be owned by MPC, a subsidiary of Southern Company. Originally, the commercial operating date (COD) for the Mississippi facility was to Follow the COD for the Orlando site by three years. With the termination of the Orlando site, the Mississippi site will new host the ?rst full-scale demonstration of the Transport integrated Gasification technology with COD scheduled for June, 2013. TECHNICAL CONFIGURATION OF THE PLANT The technical configuration of the Mississippi plant will be very similar to the con?guration that was planned For the Orlando site and, therefore, all of the project demonstration objectives will be met with the new site. Diftbrenccs between the two sites that are relevant to the technology are as follows. - The Mississippi 1000 is based on a 2x1 combined cycle with two gasilication trains instead of a 1x1 combined cycle with a single gesitication train. Each gasi?cation train fuels a GE 7iiA+e combustion turbine, the same turbine planned for Orlando, so the gasi?eation trains are similar in size to the Orlando design. GE has already completed combustion testing with the expected syngas and found that the some burner design can be utilized for the [ignite and PRB derived syngas. . The Mississippi will use Mississippi lignite instead of PRB coal as its primary fool. Mississippi Iignite has been tested at the Power Systems Development Facility with good results. Southern Company plans to conduct a test with PRB coal in the Mississippi ihcilit during the DOE supported Demonstration Phase of the project, resulting in a wider range of fuel testing than the original Orlando site. 0 The sulfur removal and recovery system is different due to the higher sulfur content of the lignite coal. in both cases the sulfur removal and recovery system was based on commercially available technology and the most economical selection For each case. The coal drying system has been modi?ed to include a commercially available fluid bed dryer for efficient removal of the higher moisture content of the lignite coal. STATUS. SCHEDULE AND PROJECT STRUCTURE FOR THE NEW HOST SITE The Mississippi IGCC is currently in the design phase and has deliverablcs consistent with those for the Orlando site. The project will continue be structured in el phases.

Phase Design, will include Environmental Information Volume (EN) preparation and outside engineering other than KBR. Phase 3b, Construction, includes procurement, construction and startnp activities. Phase 11, Demonstration, includes activities alter the COD and is the same duration as that planned for the Orlando site. Figure 1 is a summary schedule for the Kcmper County site. An updated cost estimate will be completed in April 2008 based on the scope information generated during FEED and current market pricing. Based on the updated cost estimate and the availability of the funds for the Keinper County site, Mississippi Power will make a decision on whether to proceed with the project. its decision is made to proceed, MPC plan's to file a Petition for Facilities Certi?cate with the Mississippi Public Service Commission (MPSC), and MPSC approval would be expected by October of 2003. The Facilities Certificate is required for MP0 to construct the plant in Mississippi and include the costs of the generation resource in its retail rates. MPC believes that, as long as the proposed project. continues to be the most cost-effective, long-term option for meeting the future generation needs of its customers, the appropriate approvals will be granted. Although the next part of the design engineering beyond the initial FEED phase will begin in June, SCS does not plan to seek DOE funding for any Phase 2b activities except For preparation of the RN and related activities. Phase 3b, Construction, would begin in November with the purchase of the steam turbine. DOE reimbursement of Phase 3b costs would be contingent uponNEPA approval. With the site change, SCS is proposing that the project deliverables remain unchanged, but is proposing changes to the scope for which DOE would cost share. These changes are primarily driven by the different ownership structure of the project and have the added benefit of simplifying the management, execution, accounting and cost tracking for the project. For the Orlando site, the Orlando Utilities Commission (OUC) required that the combined cycle portion of the plant be 100% owned by OUC and, therefore, outside of the scope of the cooperative agreement. For the Mississippi site, SCS is proposing that the entire IGCC, including the combined cycle portion of the plant, be in the scope of the cooperative agreement. However, as shown in the attached cost estimate, 808 is not asking For DOE to cost share SCS MPC labor, SCS MPC travel and KBR design and procurement labor, Even with these changes Southern Company?s proposed cost share will increase significantly. ?thc Recipient considers the mum-ht Furnished herein to contain con?dential business infommioa which is to he withheid from disciosute outside the US- to the extent permitted by hw.
