New Orders SGT5-2000E• One set Si3D stage 3-4 including Power Limit Increase



Changing energy market Challenges

Wind and solar power enter the market with huge capacities

Generation side

Financial crisis and Euro crisis impacting the economy

Massive changes in fossil power generation profile (daily)

Consumer side

Reduction of industry production /increase of efficiency

Reduced power consumption



Changing energy market Opportunities

LNG terminals installed in Netherlands, UK and Spain leading to a broader sourcing base

LNG

The USA have explored big resources of shale gas

Reduction of gas prices expected over mid and long term

improved competiveness for gas turbines

Unconventional Gas

Gas price dropped within US market by 60%

USA started export of LNG to the world market

Canada / Russia / Australia also start to explore their reserves
