Abstract:
The objectives of this research are to assess wind power cost per kWh of electricity produced using
three chosen wind-machines, 950 kW, 1500 kW and 3000 kW at 5 locations within the central,
southern and north-eastern regions of the country. These sites cover Lao-lue village Kao-khow
district Phetchabun province, Faitha village Sichorn district Nakhon Si Tharnmarat province,
Neung village Koh-pangan district Surat Thani province, Namphu village Patiu district Chumphorn
province and Yangkham village Kangkrow district Chaiyaphum province. An analysis of economic
viability of wind power generated by the chosen locations have been carried out by focus on three
decision criterias namely net present value (NPV), internal rate of return (IRR) and benefit--eost
ratio (B/C).
The result of study are reported that the calculated costs per unit of wind-generated power are
illustrated the costs effective range between around 2.46 and 5.17 bath per kWh for all sites except
Yangkham village Kangkrow district Chaiyaphum province. For economic analysis, the evaluations
are shown that NPV of all sites are positive and B/C ratios are bigger than 1 where IRR are greater
than the cut off point of 10.75% excluding Yangkham village Kangkrow district Chaiyaphum
province.
