Power Purchase
Options:• Embedded Retail Generator – market price• Net Metering – to 500kW• RESOP – Renewable Energy incentive• CESOP – Clean Energy incentive - ??• Green Energy Act – will replace RESOP

Renewable Energy Standard Offer Program (RESOP)
• Launched in Nov 2006• 11c/kWh + 3.52c/kWh for peak• 20 year contract with OPA• Up to 10MW, 50kV• Requires a CIA• Green, Yellow & Orange zones• Driver for flood of projects• Suspended in May 2008• Biogas OK to 5MW• Will be superseded by Green Energy Act

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

Hydro One Queue
Substation Capacity = 20MW
Queue Position Project
1 111 (10 MW)
2 222 (10 MW)
CIA Pending 333 (10 MW)
CIA Pending 444 (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

Hydro One Queue Analysis
Project Size Applications
<500kW 39
501kW - 8.99MW 184
9 - 10MW 971
Full Substations 117 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

Wind & Farm Biogas
Wind & PV Farm Biogas
Typically 9-10MW Generally <500kW
Multiple applications financed by large corporations
Individual applications financed by farmers
Flexible on location Tied to farms
30-35% capacity factor 70-100% capacity factor
Competition between generators Co-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

Distribution Code Modification
12th February 2009 Amendment• Up to 250kW: Queue exempt on feeders
below 15kV• Up to 500kW: Queue exempt on feeders
above 15kV

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
Biogas Workshop10th March 2009

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

Grid Connection Process
1. Initial Feasibility Assessment2. Connection Impact Assessment
– Gives queue position– 12 months to CCRA
3. Connection Cost Estimate4. Connection Cost Recovery Agreement5. Connection Agreement

Grid Connection Process
• Distribution Code timescales not met – Hydro One swamped
• Generator responsibility for connection design, equipment procurement and protection design
• No simplified process for small generation

Terryland Farm 180kW Biogas
• Form A submitted Sept 2006
• CIA issued May 2007
• Commissioned August 2007
• Major delay due to Anti-islanding Protection

Fepro Farms 499kW Biogas
• July 2007 – 1st Form B and CIA
• Highlighted several areas of unclear connection policy
• Pilot for new Anti-islanding protection strategy
• Scheduled for March 2009
