7. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection Grid Access Rights No guaranteed access rights Distribution Code has limited capacity Until 12 February 2009, Distribution Code was ‘First-come First-served’ for all generation in 10kW-10MW range

8. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection Hydro One Queue Substation Capacity = 20MW Queue PositionProject 1111 (10 MW) 2222 (10 MW) CIA Pending333 (10 MW) CIA Pending444 (500 kW) Capacity limits due to feeder, switchgear and transformers Speculative projects ahead in the queue could delay your application by 2-3 years per project

9. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection Hydro One Queue Analysis Project SizeApplications <500kW39 501kW - 8.99MW184 9 - 10MW971 Full Substations117 of 151 From Hydro One queue 31-Oct-08 Over 80% in 9-10 MW range Blockages started in windy areas – Great Lakes Blanket applications in Eastern Ontario Aug/Sept 07 Small biogas being shut out from many agricultural areas

10. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection Wind & Farm Biogas Wind & PVFarm Biogas Typically 9-10MWGenerally <500kW Multiple applications financed by large corporations Individual applications financed by farmers Flexible on locationTied to farms 30-35% capacity factor70-100% capacity factor Competition between generatorsCo-operation between farmers Grid access is first step - companies forced to speculate No speculation, but forced to rapidly submit Form Bs Removes opportunity for small biogas No significant impact on wind farm development

11. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection Distribution Code Modification 12 th February 2009 Amendment Up to 250kW: Queue exempt on feeders below 15kV Up to 500kW: Queue exempt on feeders above 15kV

12. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection Grid Connection Costs All costs up-front – unlike load customer Distribution Network designed for load customers Deep Entry – Watch out for $$$: –Protection upgrades –Anti-islanding protection –Recloser replacement –Voltage regulators

13. Biogas Workshop 10 th March 2009 ANF Energy Solutions Inc Power Purchase & Connection The Single-phase Hydraulic Recloser Extensively deployed across Ontario Restores load customers in 1-2 seconds Simple, reliable Can be a big problem for generation
