Economics “CHP/ Pellet Plant”
Power / Wood Pellets / District Heat
Revenues
Based on 5‐10 MWH's Electric – 25‐30 MWH’s Thermal x 8000hr
• Green Power 40 – 80,000 Mwh @ $120/mwh ‐ $5 – 10,000,000 P/A
• Wood Pellets 100,000 ton @ $100 P/A Millgate ‐ $10,000,000 P/A
• District Heat 90 – 130,000 Mwh @ $25/mwh ‐ $2 – 3,000,000 P/A
Gross Revenue ‐ $17 ‐ 25,000,000 P/A
Capital investment (approximate estimate) $50 – 60,000,000
•CHP Plant 5‐10 mwh EL – 25‐30 mwh Th ‐ $35 – 40,000,000•Pellet Plant 100,000 ton P/A capacity ‐ $15 – 20,000,000
