2. 2 GE Energy Jenbacher gas engines Separator sheet Use this range of background colors to introduce new sections Pre-Construction Phase

3. GE Energy’s Jenbacher gas engines A leading manufacturer of gas fuelled reciprocating engines for power generation applications: Power range from 0.25 MW to 4 MW, 4 platforms / 11 products Fuel flexibility: Natural gas or a variety of renewable or alternative gases (e.g., landfill gas, biogas, coal mine gas) Plant configurations: Generator sets, cogeneration systems, container solutions Installed base: more than 7,000 units / 8,000 MW Worldwide more than 800 engines in operation on biogas Distributed in Eastern Canada through DDACE Power Systems

4. Customer’s Responsibility during Pre- Construction Phase Provide biogas volume & composition information Provide site information: –Is equipment to be installed in building or a green field site that can accommodate a containerized system –Can heat be used elsewhere (barn, house, nearby buildings, absorption cooling etc.) or only in the digester –Is the equipment expected to run during a grid outage –Is the equipment expected to run when no biogas is available (dual fuel)

5. Responsibility of the Equipment Supplier During Pre-Construction Phase Determine optimum engine selection based on gas data provided Determine optimum system configuration: –Heat recovery requirements (steam/hot water) –Fuel treatment requirements –Dual fuel capabilities –Generator voltage –Grid connection (behind meter or direct) Provide equipment pricing and performance data Provide service and maintenance pricing Provide terms & conditions of sale

6. Additional Activities to Consider during Pre-Construction Phase Financial modeling of the CHP system – Is often required to obtain financing Apply for grid connection (Connection Impact Assessment) – Will be required to apply for RESOP contract –Equipment supplier will provide generator data or can look after CIA application as additional service to be provided Review service and maintenance options: –Preventive maintenance (any work to be performed by customer) –Corrective maintenance (cover unforeseen break-downs) –Performance guarantees –Availability guarantees –Response time guarantees –Term of service agreement

7. Questions to ask from Equipment Supplier Previous experience with biogas applications Local experience with biogas and other distributed generation applications Commitment to meet local codes & regulations (CSA, ESA, TSSA) Where is the nearest service technician located Where is the nearest parts warehouse What is the guaranteed response time in the event of an unscheduled shut-down Additional support in the event the technician cannot resolve the issue at hand Ability for remote diagnosis Technical Instruction documents –Required for system design

8. Timeline & Costs during Pre-Construction Phase Costs: All the information as described on previous slides will be provided at no cost to the customer We absorb costs incurred during the pre-construction phase as a business development expense Time Line: Budget quote: Same Day Detailed quotation for CHP equipment: 3-5 days Detailed quotation for fuel treatment and ‘unusual’ balance of plant equipment: 6-10 days Financial modelling: 6-10 days
