8 Natural Gas: Vast Energy Resource in North America 70 Bcf/d (years) Total Resource Potential (Tcf) North American Natural Gas Basins Abundant and Widespread Canada and U.S. Natural Gas Resource Estimates 125 Resource 100 Reserves Technology Continues to Unlock Shale Gas 0 PGC/NEB 2006 EIA/NEB 2007 EIA/NEB 2009 PGC/NEB 2009 PGC/NEB 2011 Over a 100 Year Supply at 70 Bcf/d 0 8 Source: EIA, NEB, PGC, IHS Energy, CSUG

9 Power Generation Capacity Additions Coal and Nuclear units are aging. Nearly 80% of coal units are 30 years old or more Nearly all nuclear and coal capacity in service before 1990 Natural gas dominates Major natural new capacity gas additions after 1990 in the 2000 s 9 Source: Energy Information Administration (EIA)

10 Gas as the New Fuel Abundant Domestic Cheap Clean 10

11 A good example of this new natural gas landscape is playing out right 11 here at the BC / Yukon border...

20 20 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 Wartsila Tri Fuel Power Plant in DR: LNG / Diesel / HFO 21

22 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 2222 Wärtsilä 2011

23 Electrical efficiency (%) Energy Efficiency - Best Simple Cycle efficiency available - The multi unit gas engine power plant has very high part load efficiency 45% 40% 35% 30% 5 x 20V34DF Industrial GT 25% 20% 15% 10% 5% 0% Plant Electrical Power (MW) Source: Alstom product broschure 01; Wärtsilä perf 23

24 Derating factor Energy Efficiency Reciprocating Gas engines offer stable output and high performance at high altitudes Gas turbine and gas engine output derating due to altitude (at 15C, ISO conditions for GT:s) V34SG (radiator cooling) Wartsila 20V34SG Aeroderivate Gas turbine Industrial Gas turbine Metres above seal level

25 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 25

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 26

27 Other Reciprocating Engine Advantages: 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 27

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) 28 2

29 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 29

32 Wartsila Flexicycle Dual Fuel 216 MW LNG/HFO Quisqueya 1 Combined Cycle Barrick Gold, Pueblo Viejo Gold Mine Combined cycle mode for competitive large base load power» 52.1% plant efficiency» Switch back to simple cycle on the run 32

33 Flexicycle Combined cycle Engine preheating by steam x 18V50SG + ST 1. Heat Recovery Steam Generator (HRSG) 2. Feed Water Tank Steam Turbine 4. Condenser 5. Condensate preheater 4 6. Auxiliary Boiler 7. Cooling Tower Engine preheater 33

34 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 34
