Grid Stability, why?

20 202020 % RES by 2020RES = Renewable Energy Sources

• Greenhouse gas emissions -20%• Renewable energy share minimum 20%• Energy efficiency increase by 20%• To be done by year 2020

SMARTPOWER

GENERATION

All in one!

• High electrical efficiency• Insensitive to ambient

conditions• Multiple units

– Wide load range ~ 3 … 100 %– Same high efficiency at any

plant load

• 30 sec from plant start to synchronization & 20 % load

• 2 minutes to 100 % load• 1 minute to stop• Unlimited starting & stopping,

with no maintenance impact• Fast ramping up & down• Ultra fast grid back start

• Multi-fuel capability– Natural gases, LNG,

shale gas, bio gases– HFO, LFO, Crude– Liquid bio fuels

• Fuel conversions

Smart Power Generation – Main features

Maximum efficiency = Highest energy efficiency, lower emissions, dramatic savingsSmart Power Generation concept system savings have been proven in several power systemsSPG can provide spinning reserve while it is NOT spinning, using no fuel

Smart Power Generation global promise

Smart Power Generation is a new concept which enables an existing power system to operate at its maximum efficiency by most effectively absorbing current and future system load variations, providing dramatic savings.Wärtsilä is the leader inSmart Power Generation!

Jordanian power generation by technology type

BEFORE ENGINE PLANTS INSTALLED• All plants are cycling with low

efficiency (sub-optimal)

AFTER 850 MW ENGINE PLANTS INSTALLED• Steam plants and CCGT plants

provide stable base load with optimized efficiency

• Engine plants provide load following capacity with high efficiency

Texas, USA, 200 MW Gas – Fast market player

Quotes:John Packard, Manager of Generation, STEC: “These flexible units have allowed us to respond to changes in the grid when the wind stops blowing and ....the ability to dispatch these units in increments that fit our load, allows us to keep the units at peak efficiency rather than partially load.... the biggest economic drivers is again that flexibility”
