1. Sam Jackson Southeastern Region GIS Efforts University of Tennessee Office of Bioenergy Programs Knoxville, TN 37996-4570 865.946.1130 samjackson@tennessee.edu Research Assistant Professor

2. Overall Efforts/Project  Continuation literature review for data and information in previously conducted studies  Collecting data related new and current feedstock studies in the region (switchgrass, woody biomass, crops, etc)  Significant work on woody biomass availability and siting models done

3. Biofuels Facility Location Analysis Modeling Endeavor  Brad Wilson, Burt English  Biorefinery site evaluation in 16 southeastern states  Combines:  Suitability analysis based on geographic features  Feedstock supply analysis

4. Currently focused on switchgrass as the feedstock Uses crop zones derived from SSURGO soils database and county boundaries BIOFLAME

5. Incorporates: – Transportation networks – roads, rail, barge – Crop yield, budgets, price, and land-use information Model calculates break-even price for crop competition, marginal costs of transportation, and identifies optimal sites BIOFLAME

6. Input Parameters

7. Suitability Analysis Showing areas near major roads, railroads, navigable waterways, and major cities

8. Biorefineries and Feedstock Eight facilities sited across Tennessee with associated feedstock

9. Site Comparison Output table showing cost breakdown and crop acreages converted to switchgrass production

10. Expansion to more states and energy feedstocks Increased resolution for crop zones to field level Increased resolution of crop yield information using models like EPIC or ALMANAC Preprocessing/depot collection facilities Addition of: – Policy implication function – Ethanol demand function Ideas for Improvement/Future Plans

11. BioSAT: A web-based biomass site assessment tool Timothy M. Young, Donald G. Hodges, Timothy G. Rials – UT Robert C. Abt – NCSU James H. Perdue, Andy Hartsell – USFS
