  1. HULL WIND II A FRESH BREEZE OFF THE LANDFILL Presentation to Northeast States-EPA Workshop Siting Renewable Energy Projects at Closed Solid Waste Landfills and Contaminated Sites June 25, 2008 Engineers Scientists Consultants www.essgroup.com

  2. HULL WIND II • BACKGROUND: • History of Success – Hull Wind I • Municipal Lighting Plant – Local Knowledge and Expertise • Town Land For Reuse • Community Support

  3. HULL WIND II • Hull Sanitary Landfill Siting Considerations: • Available open space • Proximity to system interconnection • Prevailing wind conditions • Regulatory Siting Considerations: • Constructing large structures on closed landfills • Maintaining liner integrity • Maintaining cap integrity • Ongoing maintenance and monitoring

  4. HULL WIND II • Landfill Conditions – Three Sections: • Phase 1A – closed, unlined landfill cell, capped with low permeability (clay) cap • Phase 1B – closed, unlined landfill cell, capped with flexible membrane liner (FML) cap • Location for WTG Installation • Phase 2 – lined landfill cell, active, operating area of the landfill • Locations for supporting structures; poles, ductbank

  5. HULL WIND II • Project Specifications (Phase IB)- Disruption of 5,000 s.f. of existing landfill cap for WTG: • Removal of existing membrane and covering soils • Placement of a pile foundation • Placement of a 20’ square concrete pad over the piles to support WTG • Replacement of existing FML within disturbed area with 40 mil HDPE membrane welded to existing membrane to restore cap integrity • Cover with 12” of drainage sand and 6” of vegetative support soil (loam)

  6. HULL WIND II • Project specifications (Phase 2): • Utility poles (2) placement supporting overhead transmission lines for interconnection • Waste depth at pole locations in excess of 20’ • Poles set at 6.5 ft. BGS to maintain liner • Placement of underground duct bank from WTG to switch gear to new overhead power line • Bottom of duct bank approx. 30” BGS to maintain liner

  7. HULL WIND II • Costs and Benefits: • $ 3,000,000 construction cost • $ 31,000 annual maintenance and insurance cost • Value of electricity approx. $0.10/kWh which would otherwise be purchased to respond to Hull demand

  8. HULL WIND II • Since June 22, 2006 (date of commission): • 7,767,600 kWhs generated (23.3% capacity) • $ 776,760 avoided energy costs • $1,800,000 received for RECs • No emissions • No fuel spills • No unscheduled outages
