Pre-Construction Phase

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

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)

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

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

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

Timeline & Costs during Pre-Construction PhaseCosts:• 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
