Power Generation Capacity Additions
Natural gas
dominates new
capacity after
1990
Nearly all nuclear and
coal capacity in service
before 1990
Coal and Nuclear units are aging. Nearly 80% of coal units
are 30 years old or more
Major natural
gas additions
in the 2000’s

Gas as the New Fuel
•Abundant
•Domestic
•Cheap
•Clean

A good example of this new natural gas landscape is playing out
right here at the BC / Yukon border...

Reciprocating Engine Value Proposition
21
Fuel Flexibility
• DUAL FUEL Natural Gas and Liquid Fuels
•Ability to change between liquids and gas on-line
•Renewable Fuels eg. biodiesel

Fuel Flexibility
•Dual Fuel: back-up when primary fuel supply is disrupted
•Set up dual fuel when you know LNG is coming..
•Can utilise the cheaper fuel if prices swing

Operational Flexibility
• 5 minute start
• Unlimited starts/stops per day, per year
• No starting costs or equivalent running hours
• No minimum run time or up time
26
Operational Flexibility
• High Reliability
– Multiple units – each unit is an isolated system
• High Availability
– Maintenance done on site during non-critical hours, involving one unit at a time
• Rugged Design
27
• Negligible water consumption with closed loop cooling
• Uses low pressure gas
– 75 psig gas – no need for aux. gas compressor. Can use gas directly from the LNG tank.
• No output degradation
– Full output through the lifecycle of the plant
– Negligible heat rate degradation between overhauls
Other Reciprocating Engine Advantages:
28
Low Emissions
• Nox - Nitrogen oxides: 5 ppm (0.064 g/kWh) (as NO2)
(dry, at 15 vol-% O2) - with SCR
• CO - Carbon monoxide: 15 ppm (0.12 g/kWh)
(dry, at 15 vol-% O2) - with CO catalyst
• VOC 25 ppm (0.12 g/kWh)
(dry, at 15 vol-% O2)
• Particulates (total) (0.12 g/kWh)
(at 15 vol-% O2)

Plant Aesthetics
• Design makes the project look like a typical warehouse
• No visible smoke, fumes or steam release
• Noise according to local codes. Typically 70dB at the fence

Conclusion
• LNG: domestic, abundant, cleaner & cheaper than oil
• Easy fuel to use for power generation• Requires LNG storage tanks / Vaporiser
• Dual Fuel option provides flexibility & reliability
• Various configurations of plant depending on size and need
• Modern reciprocating engines offer many advantages over other technologies
