Development of technology and industry has been causing a remarkable energy demand all around the world. In order to meet this huge energy demand, conventional energy sources are being used a lot and this issue brings along a serious environmental pollution. Especially, last decades many countries have signed the agreements to prevent environmental pollution. In conjunction with these events, renewable energy sources have become important. In this context, most of countries have been increasing the incentives to the clean energy systems. Also, Turkey has been increasing the incentives to renewable energy investments; therefore renewable energy usage is increasing day by day. In 2015, Turkey’s total installed capacity has reached 72146.7 MW and 42.7% of this amount is met by renewable energy sources. In Turkey most commonly used renewable energy sources are hydroelectric energy, wind energy, solar energy and geothermal energy respectively. In 2013, installed wind energy capacity of Turkey was 2759.6 MW and this capacity reached 4503.2 MW in 2015. It can be deduced from this data, wind power investment in Turkey has been expanding dramatically. In this study, a wind power plant (WPP) feasibility study for Gemlik region in Bursa Province is released by using 5 number of Vestas V90 commercial wind turbines. Also, climatology data obtained from Turkish State Meteorological Service are used for this study and by applying these date to the Windsim software; annual energy production (AEP) and capacity factor of the WPP are calculated. The study shows that, establishment of a WPP which has 30.6 GWh/y AEP and 34.9% capacity factor is feasible.
