<strong>Renewable</strong> <strong>Energy</strong> <strong>Resources</strong> in <strong>Oman</strong><br />
The wind m<strong>on</strong>itoring masts at Thumrait and Qairo<strong>on</strong> Hariti were inspected as<br />
part of the study in order to evaluate the measuring c<strong>on</strong>diti<strong>on</strong>s. The measuring<br />
c<strong>on</strong>diti<strong>on</strong>s have been evaluated as acceptable but due to some complexity of the<br />
terrain around the masts more detailed wind analysis are required in order to determine<br />
the wind energy resources more accurately. Photos of the meteorological<br />
stati<strong>on</strong>s at Thumrait and Qairo<strong>on</strong> Hariti and the surrounding landscape are included<br />
in Appendix 2.<br />
4.1.2 Wind energy resources<br />
A rough estimate of the wind energy c<strong>on</strong>tent at 80 m above ground level has<br />
been made at each of the five selected met stati<strong>on</strong>s based <strong>on</strong> the hourly mean<br />
wind speed data <strong>for</strong> 2006 received from DGCAM. The calculati<strong>on</strong> sheet is enclosed<br />
in Appendix 7.<br />
The annual wind energy c<strong>on</strong>tent at each met mast is indicated <strong>on</strong> Fig. 4.2. The<br />
energy is specified as kWh per year through a vertical area of <strong>on</strong>e m 2 ,<br />
kWh/year/m 2 .<br />

4.1.3 Potential capacity <strong>for</strong> grid c<strong>on</strong>nected wind turbines<br />
As a general rule based <strong>on</strong> experiences the maximum wind power capacity<br />
should not exceed approximately 15 % - 20 % of the existing c<strong>on</strong>venti<strong>on</strong>al power<br />
capacity of the system in order to avoid disturbances in the power quality due to<br />
the fluctuating power generati<strong>on</strong> by the wind turbines. In case of sufficient grid<br />
capacity a higher percentage of wind turbine capacity can be c<strong>on</strong>nected to the<br />
grid.<br />
In <strong>Oman</strong> the future power system will have a total capacity of 5000 MW (2015)<br />
and the power system in the north and in the south will be interc<strong>on</strong>nected. The<br />
technical future potential <strong>for</strong> installati<strong>on</strong> of wind turbine capacity in <strong>Oman</strong> will<br />
be at least 750 MW.<br />
Another technical limitati<strong>on</strong> <strong>for</strong> installati<strong>on</strong> of wind power capacity is the availability<br />
of open land without obstacles <strong>for</strong> erecti<strong>on</strong> of the turbines.<br />
