<strong>Renewable</strong> <strong>Energy</strong> <strong>Resources</strong> in <strong>Oman</strong><br />
Wind turbines designed <strong>for</strong> low wind c<strong>on</strong>diti<strong>on</strong>s are characterised by a large<br />
swept rotor area in relati<strong>on</strong> to the capacity, and an increased hub height. Low<br />
wind turbines are suitable <strong>for</strong> wind c<strong>on</strong>diti<strong>on</strong>s in <strong>Oman</strong>.<br />
Modern wind turbines are equipped with cooling systems enabling operati<strong>on</strong> under<br />
extreme envir<strong>on</strong>mental c<strong>on</strong>diti<strong>on</strong>s such as the high air temperatures which<br />
occur in <strong>Oman</strong>.<br />
Utilisati<strong>on</strong> of the wind energy resources in the southern part of <strong>Oman</strong> should be<br />
further investigated. We recommend a detailed wind resource survey and further<br />
analysis of the potential c<strong>on</strong>necti<strong>on</strong> of wind turbines to the Salalah Power System.<br />
Other renewable energy technologies<br />
The study finds <strong>on</strong>ly limited potential <strong>for</strong> producing electricity using other renewable<br />
energy resources such as geothermal energy, wave energy and biomass.<br />
C<strong>on</strong>sequently, we are not recommending the implementati<strong>on</strong> of large scale electricity<br />
producti<strong>on</strong> based <strong>on</strong> these energy resources at this time.<br />
2.2.3 Technical potential of renewable energy<br />
Solar energy, photovoltaic systems<br />
The theoretical potential <strong>for</strong> electricity producti<strong>on</strong> in <strong>Oman</strong> using solar energy is<br />
significant.<br />
The technical potential <strong>for</strong> electricity generati<strong>on</strong> by grid c<strong>on</strong>nected PV systems is<br />
determined by the area available <strong>for</strong> installati<strong>on</strong> of PV cells (e.g. <strong>on</strong> buildings,<br />
parking areas etc). Assuming that 50% of the houses in <strong>Oman</strong> are suitable <strong>for</strong><br />
installati<strong>on</strong> of PV cells and the area available at each house is 20 m 2 the total potential<br />
area would provide space <strong>for</strong> an installed capacity in the order of 420<br />
MW, and a potential annual electricity producti<strong>on</strong> of 750 GWh/year which corresp<strong>on</strong>ds<br />
to 5 % - 6 % of the present annual electricity demand (13,900 GWh in<br />
2007). PV systems can also be located in the desert. Typical capacity per m 2 of<br />
land is about 30 Wp (Watt peak) corresp<strong>on</strong>ding to 30 MWp per km 2 .<br />
The technical potential <strong>for</strong> electricity generati<strong>on</strong> by PV systems operating with<br />
diesel gen-sets and battery storage capacity in isolated off-grid power systems is<br />
assumed to be 20% of the present electricity generati<strong>on</strong>. This corresp<strong>on</strong>ds to 70<br />
GWh/year and a solar PV capacity of 40 MW. By using a fracti<strong>on</strong> of 20% a major<br />
part of the generated electricity can be used directly and <strong>on</strong>ly a minor part has<br />
to be stored.<br />
The potential <strong>for</strong> utilising PV cells as power supply <strong>for</strong> small equipment and<br />
lighting is large. Presently the oil industry has PV cell capacity available <strong>for</strong> operati<strong>on</strong><br />
of small equipment in remote areas. Due to the small capacity of this type<br />
of power supply the c<strong>on</strong>tributi<strong>on</strong> to the total electricity generati<strong>on</strong> by solar power<br />
is relatively small, but should not be overlooked.<br />
The potential <strong>for</strong> producing electricity using PV systems is highest during the<br />
summer which coincides with the period of peak electricity demand in <strong>Oman</strong>.<br />
