Italian-Thai Development Public Company Limited on behalf of Thailand's Provincial Electericity Authority (PEA) will be laying 33kV submarine cable to Koh Siboya, Koh Pu, Koh Phi Phi, Railey Bay, and Koh Lanta. The cable will be delivered in October 2008 and will be installed by ITD's Marine Department.
For this project, World Leader in Cable Manufacture, Nexans shall supply over 33.3 km, in two lengths, of XLPE insulated, lead sheathed, copper conductor 3-core 33 kV submarine cable, with an integrated fibre optic element. A single 3.8 km length of cable, with a cross-section of 120 mm2, will be used for the Raile Bay crossing.
The remainder of the cable, with a cross-section of 185 mm2, will be used to create three power links between the islands of Koh Pu, Koh Phi Phi Don and Koh Siboya - total approximate length of 27 km, as well as the 2.5 km Koh Lanta island interconnection.
This will put an end to the power limitations on the Islands and with the increase in tourism and the residential property market the PEA anticipates additional power capacity will continue to grow by 10 to 15 per cent per annum.
Earlier plans to lay underground cables have been scrapped due to worries of damage to coral reefs on the route however in the new contract, suppliers have been required specifically to avoid any contact with reefs.
The plans will for the first time bring reliable stable power to Railey Bay, Koh Jum and Koh Siboya where at present generators can provide only a limited service. For Koh Jum and Koh Siboya, the integrated fibre optic cables will bring phone lines and fast internet connections for the first time really opening up the potential for tourism but particularly for high end villa construction.
