  • 1. PUBLIC-PRIVATE PARTNERSHIPS FOR GAS UTILIZATION SYSTEMS IN THE REGION OF WATERLOO Linda Churchill, Waste Management Region of Waterloo April, 2010
  • 2. PRESENTATION AGENDA  Landfill Gas Collection Systems  Rationale for Private Sector Involvement  Request for Proposal Process  Successful Proponents and Utilization Details  Benefits of Collecting & Utilizing Landfill Gas  Key Points in the Agreements with the Private Sector  Waterloo Region’s Experience with Public-Private Sector Partnerships
  • 3. WATERLOO WASTE MANAGEMENT SITE
  • 4. LANDFILL GAS DETAILS  Causes Odours  Potent GHG - over 20x the Negative Impact of Carbon Dioxide  Landfills Account for 25% of Manmade Methane Emissions  Explosion Hazard under Certain Conditions
  • 5. Landfill Gas Composition 6% 39% 55% Methane Carbon Dioxide Nitrogen
  • 6. Waterloo Gas Collection System  Initially installed in 1995  Several System Expansions  103 Vertical Wells & 12 Horizontal Trenches  Draw Placed on Well Field  Avg. Flow of 2,000 cfm  Enclosed Flare  Total Capital Cost of $6 Million
  • 7. Cambridge Gas Collection System  62 Vertical Wells, 5 Horizontal Collection Trenches & 18 Vertical/Horizontal Disposable Wells  Draw Placed on Well Field  Avg. Flow of 500 cfm  Enclosed Flare  Capital Cost of $1.5 Million
  • 8. Rationale for Gas Utilization & Private Sector Involvement  Recognition of a Potentially Valuable Resource  Limited Region Budget for Energy Resource Development  Realization that the Utilization Project Is Outside The Waste Management Scope  Relevant Technical Experience Outside of Region  Potential to Offset the O&M Costs and Capital Cost Incurred by the Region  Reasonable to Pursue Private Sector Utilization
  • 9. Request for Proposal Process  RFP’s Issued for Waterloo in 1994 and in 1995 for Cambridge  Evaluation Criteria Included Environmental Considerations, Experience, Revenue for the Region, Technology  Region Evaluated Proposals  All Proposals Viable, Selection Based Upon Financial Considerations  Regional Council Approved Proponent Selection
  • 10. Successful Proponent for Gas Utilization at the Waterloo Landfill  Toromont Energy Ltd  Generates 4.2 MW of Energy  Royalty Paid to the Region on a Sliding Scale  Electricity Production Began Sept. 1999  Capital Cost Over $7 Million  Emission Credits belonged to Toromont & Toromont sold to OPG
  • 11. Successful Proponent at the Cambridge Landfill Site  Gerdau Courtice Steel  Replacement for Natural Gas  Payment Based upon Energy Content  Start-Up Began Sept. 1999  Capital Cost of Approx. $2 Million  Region Retains Credits
  • 12. Benefits of Collecting and Utilizing Landfill Gas  Reduces Odours  Reduces Migration of Explosive Gases  Reduces Greenhouse Gas Emissions  Uses an Energy Resource otherwise Flared  Offsets Energy Production by Other Means - Fossil Fuels  Revenue Generation Mechanism for the Region -- $350,000 in 2007 to Est. $800,000 in 2010  Revenue Used in the Operation & Expansion of Gas Collection Systems
  • 13. Key Points in the Private Sector Agreements  Proponent Responsible for Design, Construction, O & M of Facility  Approvals the Responsibility of the Proponent  Region Does Not Guarantee Gas Quality or Quantity – Gas Collection Operated for Odour Control  Region Retains Operation of the Collection Systems  Region Agreed to Reasonably Cooperate with the Proponent  Terms of Payment Detailed in Each Agreement  Terms of Agreement to Last 20 Years
  • 14. Waterloo Region’s Experience with Public-Private Sector Partnerships  Recognition of Feasibility of Utilizing Landfill Gas as an Energy Resource  Practical to Have Private Sector Develop the Resource  Request for Proposals Issued in 1994 and 1995  Agreements Signed in 1998  Win-Win Project for the Public and Private Sector as well as the Environment  Revenues Generated Have Offset O&M Costs  Reduced Greenhouse Gas Emissions from Landfills
  • 15. Conclusion " Toromont’s relationship with the Region has been awesome. Region recognizes the benefits of a strong business relationship, has been very accommodating with respect to contract amendments, employs dedicated, competent people, and reinvests its royalty payment back into the landfill collection system which further benefits both Toromont and Region. Royalty payment contract is a successful approach. It has permitted each party to do what they do best. " Lou Colangelo, Toromont Energy, April 2010
