OUTLINES 1. The Main Energy Issues for Turkey 2. Current status of coal based power plants in Turkey 3. Needs for retrofit and new building of power plants 4. Comparision of Coal Combustion Technologies 5. Trends on clean coal technologies 6. Conclusion
The Main Energy Issues for Turkey 1. Security of energy supply 2. Sustainable development 3. Lack of technological knowledge Besides these
¬Energy demand is growing (minimum %60 increase until 2030), ¬The energy dependency is increasing (current ratio is %73), ¬The total energy investments will be above 120 billion Euro until to 2030.

Ref: Bütün S., 27. Energy Efficiency Week, 10-13 January 2008, Electricity Generation Co.Inc., Increasing Efficiency of Electricity Production Plants and Evaluation of Waste Heat.
Current Situation of Turkish Coal Based Power Plants Most of the plants in Turkey • is based on pulverized coal combustion technology with relatively low presure and temperature, • has an efficiency of maximun %38 (but average is %32-33, • has an average age of approximately 28 (close to the end of economical lifetime), To increase the efficiency and also minimize the emmision • retrofit for steam cycles, combustor and emmmision control units or • replace the units with new ones in the near future are mandatory.
Possible time schedule for building a new power plant Planning 1-2 years
Eng&Construction 4-5 years

So, avoid imposing unacceptable burdens to the economy, the suitable technologies for a new power plant should be evaluated / selected by considering the technology trends for ZEPPs.
