The AEP of a MW wind power plants installed in Tha
Chana Surat Thani province was 3.83-5.03 GWh/year.
Chana in Surat Thani province is the most suitable area
for a MW wind turbine generator installation followed by
Chana in Songkhla province respectively.
The capacity factors of a MW wind power plant
operated under wind energy resource of southern
Thailand were in the range of 5.49-14.58 % as shown in
Fig. 16. It was found that the more mean wind speed the
higher capacity factor. The capacity factor of a MW wind
power plants installed in Surat Thani province were in the
range of 14.36-14.58%.
The cost of energy produced by wind power was in the
range of 9.4-25.4 cents/kWh as shown in Fig. 17. For the
potential sites especially in Surat Thani province, the cost
of energy was 9.4 cents/kWh.
The CO
2
emission avoidance from the operation of a
MW wind power plants in southern Thailand were in the
range of 1,010-7,700 kton CO
2
/year except at Hat Samran
due to the lowest AEP as shown in Fig. 18. The
avoidance of CO
2
emission from the operation of 7 MW
wind power plants installed in Surat Thani province was
totally 5,318 kton CO
2
/year.
The financial indices to achieve the wind farm power
plant consist of BCR, NPV, FIRR and PBP as shown as
in Fig. 17-22. Result showed that a BCR in the range of
1.17-1.87, a NPV in the range of 2.90-6.60 MUS$, a
FIRR in the range of 3.24-15.64% and a PBP in the range
of 5-8 year respectively. The economy analysis reply to
Tha Chana in Surat Thani was the bester than another
areas.

ONCLUSION
Based on this study, it is concluded that the wind
resource and the 1 MW wind turbine generator
installations along the coastal line of the Gulf of
Thailand, especially in Surat Thani province, were utmost
possible due to the highest AEP produced by wind energy
and the AEP were in the range of 3.83-5.03.3 GWh/year.
The corresponding capacity factors of a MW wind power
plants were in the range of 5.58-14.5%. The CoE
produced by wind energy especially at the potential sites
in Nakhon Si Thammarat province were in the range of 3-
6 cents/kWh. Finally, it was found that the 18 MW wind
power plants operation in southern Thailand could avoid
the CO
2
emission about 118,729 kton CO
2
/year. A
feasibility study showed that there is potential wind
energy resource for a MW wind turbine generator
installation along the coastal line of the Gulf of Thailand
especially at Surat Thani province in southern Thailand.
