6. A Network IntegrationOriented Model ToEvaluate New WindPowerGenerationProjects • Introduction • We have an unused renewable energy sources capacity • Renewable Energy: is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished)

7. A Network IntegrationOriented Model ToEvaluate New WindPowerGenerationProjects • Factsaboutrenewableenergycapacity • The electricity demand in Turkey will increase from 196,000 GW in 2008 to 363,000 GW in 2017 (General Directorate of Energy Affairs) • Turkey ranks 1st in the world in terms of highest growth rate in wind energy plants • Turkey has wind potential to produce 160 TWh of electricity, which is twice the current electricity consumption. • With an average growth in power demand of 8% each year, this means that if the 20,000 MW target is met, wind power will cover one fifth of Turkey’s power demand by 2023 (Kjaer) • Turkey’s installed wind capacity tripled during 2007 from 50 MW to almost 150 MW. It tripled again during 2008 to reach 433 MW, and by the end of 2009 it had almost doubled to 801 MW. Moreover, the Turkish Government announced a 30% objective for renewable energy by 2023 with plans to push wind energy up to 20 GW of installation is for the same year. (Kjaer)
