10 NMU Marquette Area Plants Northern Michigan University Heating Plant Stack (left) Wisconsin Electric Presque Isle Power Plant (center). Local Marquette Recorded Snow Fall as of is Already Over 150

11 Proposed New Plant Strategic Plan Ripley Heating Plant was Constructed in late 1960s Most Campus Buildings are Heated and Cooled by the Ripley Heating Plant (approx 60 buildings) Power for Campus is Centralized at the Heating Plant Randy Russell - HDR Cummins & Barnard will Discus the Combined Heat and Power Plant Addition Proposed for Construction Next to the Existing Plant

12 Michigan Upper Peninsula Snow Handling Michigan UP Snow Blower! 454 Cubic Inch Big Block Chevy V8 412 Horsepower 430 Ft-Lbs Torque

13 System Overview Existing NMU Ripley Heating Plant Three Existing Gas/Oil Fired Boilers Two Installed New in ,000 PPH 120 PSIG Three Campus Power Loops Fed From kv Switchgear New in 2006 Two New 50,000 Gallon Double Wall Underground Fuel Storage Tanks

14 Existing Campus Steam Distribution System Total Length of Existing Steam & Condensate System ~ 2 miles Total Sq Ft Heated by Ripley Plant ~ 3 Million Existing Piping is Direct Buried and Tunnel Systems New Supply to Marquette General Hospital ~ 1300 ft

15 Solid Fuel Cogeneration Plant Project Development Gas Turbine Feasibility Study Conducted in 1999 Concluded That Gas Turbine Option was Not Feasible Ripley Upgrade Study Conducted in 2004 Recommended Replacement of Two Existing Boilers Recommended Addition of New Solid Fuel Boiler Cogeneration Facility Adjacent to Existing Heating Plant

16 Solid Fuel Cogeneration Plant Project Development University Needs - Recent Study Recommendations Better Energy Efficiency Utilization of Renewable Resources Reduction of Bottom Line Costs and Large Savings Potential Better Available Fuel Resources Utilization Reasons for Solid Fuel Project Cogeneration Opportunities Cost of Natural Gas vs. Waste Wood Use of Green Product Uses Renewable Source Wood Based Steam Supply to Campus Potential for Reducing Electrical Costs

17 Solid Fuel Cogeneration Plant Project Development Recommended Circulating Fluidized Bed Design for Future Fuel Flexibility Fuel Deliveries By Truck Adjacent to Sugarloaf Road - Main Truck Route Average Wood Fuel Consumption 11 Tons per Hour Eight 35-Ton Truck Deliveries per Day Fuel Storage Wood Storage in Silos at Ripley Heating Plant Bulk Storage at Supplier Facilities Nearby Possible Use of Renewafuel (Pelletized Wood Product) Third Party Project Review Conducted By an Independent Consultant Confirmed Project Assumptions and Approach

18 NMU Solid Fuel Cogeneration Plant Effective Use of Heat in Fuel at Peak Efficiency Typical Coal Plant Energy Use 9% 660 MW example 3700 PSIG, 1050 F/1100 F Reheat 53% 38% Heat Input = 5400 MMBTU/Hr Useful Heat (Electric) = 2050 MMBTU/Hr Useful Heat (Steam) = 0 MMBTU/Hr Total Useful Heat = 2050 MMBTU/Hr Useful Heat Waste Heat Auxiliary Power Auxiliary Power = 500 MMBTU/Hr Wasted Heat = 2900 MMBTU/Hr

19 NMU Solid Fuel Cogeneration Plant Cogeneration or Combined Heat & Power CHP Plant Energy Use 9% 8 MW Ave / 10 MW Max 70,000 lb/hr Extraction Steam for Heating 29% 62% Heat Input = 136 MMBTU/Hr Useful Heat (Electric) = 22 MMBTU/Hr Useful Heat (Steam) = 70 MMBTU/Hr Total Useful Heat = 92 MMBTU/Hr Useful Heat Waste Heat Auxiliary Power Auxiliary Power Wasted Heat = 9.7 MMBTU/Hr = 34.3 MMBTU/Hr

20 Solid Fuel Cogeneration Plant STG Heat Balance Diagram Net Output 9 MW (s) 7 MW (w) Aux Power ~ 1 MW Extraction Steam to Campus Distribution Header 30 k PPH (s) 95 k PPH (w)

21 Solid Fuel Cogeneration Plant Fuel Considerations Fuel Availability Wood Residue Chips, Bark, Fines, Mixed, Other Over 1 Million Tons per Year Produced in Upper Peninsula Marquette County 250,000 Tons per Year Several Lumber Companies & Mills within 150 Miles Of Marquette

22 Solid Fuel Cogeneration Plant Technical Considerations Wood Fuel Sourcing Study: Contacted Area Wood Suppliers and Processors Held Group Meeting to Discuss Project Response Was Very Positive

23 Solid Fuel Cogeneration Marquette General Hospital Partnering Conducted Hospital Steam Consumption Study Annual Steam Flow Range Low Average ~7,000 PPH Low Peak ~10,000 PPH High Average ~18,000 PPH High Peak ~30,000 PPH Substantial Annual Savings for Hospital Maintain Existing Boilers for Emergency Backup

24 Solid Fuel Cogeneration Marquette General Hospital Partnering Benefits To NMU Creates Synergy with the Other Major Gas User in Area Easy to Interconnect to Existing Distribution System Reasonable Costs Compared to Benefits Provides Cash Flow to NMU Supports Overall Project Benefits to MGH Provides Substantial Yearly Savings with Minimum Risk Provides Additional Source of Steam (Redundancy) Could Result in More Cost Effective Use of Existing Hospital Space and Possibly Staff if New Facility is Built at Ripley

25 Solid Fuel Cogeneration Marquette General Hospital Partnering New 12 Steam Line to MGH Provides ~100 psi Supply at Hospital Based on 80% Diversity on NMU System Steam Loads Allows Operation at 150 PSIG at Ripley (Extraction Pressure) Allows Utilization of Existing High Pressure Hospital Equipment (Laundry, Autoclaves, etc.)

26 Solid Fuel Cogeneration Plant Research Facility Alternative Energy Research 20,000 Ft 2 Research, Conference Room, And Classroom Space Located Adjacent To Proposed Solid-fuel Boiler Plant Combines Cutting-edge Renewable Fuel Research With Training Of Students Coursework For NMU s Alternative Energy Minor Independent Student Research Projects

27 Solid Fuel Cogeneration Plant Research Facility Research Areas for NMU s 20,000 Sq Ft Research Lab: Carbon Capture Area to Study Algae Reduction of Carbon Footprint of Solid Fuel Boiler Briquette Production Area to Study Fuel Opportunity From Campus Waste Paper Stack Emissions Area to Study Gasification Of Boiler Emissions To Liquid Alcohol Fuels

28 Solid Fuel Cogeneration Plant Research Facility Algae Investigations Optimization Of Algae Growth Conditions To Use Maximal Amount Of CO 2 In A Northern Climate Gene Expression Studies To Characterize Species Of Algae & To Select Best Species To Use At NMU
