Technical and economic evaluation of energy production from wind in Istanbul and surrounds

Abstract

Istanbul is located in the northwest part of Turkey and has the greatest population of any city in the country. Istanbul and its surroundings were researched for wind potential. Energy production from wind was evaluated technically and economically in this study. Corlu, Kumkoy and Sile sites were examined. Other sites in the same region (Goztepe, Kirecburnu, Bahcekoy, Florya and Kartal) were also evaluated but the results were not satisfactory, and for this reason, these sites were not examined in this study. When we checked daily, monthly and yearly wind speed values and frequency distributions, the wind energy potential of Corlu, Kumkoy and Sile were greater than other sites. Corlu, Kumkoy and especially Sile’s wind speed data are statistically decreasing. A Nordex N117 91m hub height wind turbine can produce 6099 MWh in Corlu, 6459 MWh in Sile, 7265 MWh in Kumkoy. A Nordex N117 140 m hub height wind turbine can produce 6471 MWh in Corlu, 7439 MWh in Sile and 8175 MWh in Kumkoy. The energy costs were calculated by the average of 36 years of wind measurement data using Nordex N117 turbines. Energy costs with Nordex N117 91 m and 140 m hub height in Corlu, Sile and Kumkoy are 0.025-0,027 US$/KWh, 0.022-0,025 US$/KWh, 0.020-0,023 US$/KWh, respectively.
