6. Biomass Fueled MicroTurbine • Energy Generation Approach • R&D & Equipment Needed for Implementation • Woody Biomass Feedstock Forester’s Co-Op

7. Indirect-Fired Gas Turbine Approach Forester’s Co-Op

8. Chiptec – 2 Million BTU/Hr Gassifier • Chiptec Wood Gassifier • 17 Year Vermont Company • 99% Gasification Combustion for 2,300F Exhaust Output • Feedstock flexibility – 3” minus chip size, up to 45% moisture content, mixed species • Advanced fuel feed system • Multiple Safety Redundancy • Electronic emission and performance monitoring equip. • O&M Training and Service Contract Forester’s Co-Op

9. From Exhaust Gas to Ambient Air “Heat Exchanger” • R&D Technology Proto Type Quoted Cost @ $110,000 • R&D & Interconnect Costs have been Estimated at $1,400,000 • 84% UC Davis Modeled Efficiency • 2100F Intake – 1700F outflow pressurized to 3.5 Bars by Micro-turbine • 40% BTU Surplus from Turbine Exhaust for Space Heat to Camp • Gassifier Exhaust Deposition Research Funding proposal being developed with UC Davis • Capital Funding current being sought from Public and Private Sources Forester’s Co-Op

10. Modular Proven Off the Shelf Equipment75 kW output to CampCommitment for “Base Load-24/7” Generation“CEC” Certified Grid Interconnect “Rule 21’ StandardsAir to Air Heat Exchanger Knowledge & Leadership14% to 23% Electrical Energy Conversion Capstone Turbine Corporation Forester’s Co-Op

11. Woody Biomass Feedstock - 147 Year - Annual Supply Forester’s Co-Op

12. Advantages of the Biomass Fired MicroTurbine • Gas turbine operated on a clean working medium – Air • Heat Exchanger - Simplicity & Minimal # components • Lower environmental impacts – Eliminates the need for waste water/steam consumption or cleanup • Commercial components available for Gasification and MicroTurbine Equipment • Indirect fired gas turbines offer potentially higher over all efficiency • Modular design allows for “Base Load” expansion to onsite need Forester’s Co-Op

18. Washington Ridge “101” Minimal R&D Investments in Biomass as a fuel have been made as compared to others such as fossil fuels and nuclear. $0 Private Industrial R&D Investments in Biomass as a “Renewable Fuel” Limited public program funding available for “DG” Biomass R&D projects Venture Capital is non-existent for renewables in our uncertain energy market Forester’s Co-Op

19. Washington Ridge “101” Wood Fuel is a Good Energy Value Forester’s Co-Op

20. Washington Ridge “101” “DG” High Pressure Steam systems not cost effective -Capital outlay, Fuel consumption, Full Time Attendant (Cal-OSHA), Safety, and Water requirement No “Turn-Key” “DG” biomass conversion “Base-Load” equipment Available Forester’s Co-Op

21. Washington Ridge “101” • Large utilities are followers and are disinterested in supporting Renewable “Distributed Generation” & grid interconnect Forester’s Co-Op
