The potential of electricity generation on the east coast of Red Sea in Egypt
Wind characteristics have been analyzed based on long-term measured data of monthly mean wind speed of seven meteorological stations along the east coast of Red Sea in Egypt. It was found that the windiest stations (Region A) namely (Zafarana, Abu Darag, Hurghada and Ras Benas) have annual mean wind speeds (7.3, 7.2, 6.4 and 5.5 m/s) at 10 m height, respectively. Numerical estimations using measured wind speeds and frequencies to calculate the two Weibull parameters were carried out and two methods were applied. The methodical analysis for the corrected monthly wind power density at a height of 10 m above ground level, over roughness class 0 (water), for each station was done. The recommended correlation equation was also stated for Red Sea zone in Egypt. Also the corrected annual wind power density at the heights (50-70) m was obtained for all stations. Moreover, calculations show that the four stations in (Region A) have a huge energy potential available (430-1000 W/m(2)) at 70 m height, while Quseir and Suez stations (Region 13) have good wind power density (170-190 W/m(2)) at 50 m height. A technical and economic assessment has been made of electricity generation from two turbines machines having capacity of (1000 and 600 kW) considered in Regions A & B, respectively, using WASP program. The yearly energy output, capacity factor and the electrical energy cost of kWh produced by the two different turbines in each region were estimated. The production costs of four stations in Region A was found to be less than 2Euro cent/kWh and compared with retail tariff. (c) 2005 Elsevier Ltd. All rights reserved.
