ONCLUSIONS
In this work, a high resolution wind atlas for Nakhon
Si Thammarat and Songkhla Provinces in southern
Thailand was developed using combined mesoscale,
MC2, and microscale, MsMicro, modeling techniques.
The model inputs consist of long-term statistical climate
data, i.e. the NCEP/NCAR database, high resolution
topography and land cover data. The 200 m resolution
wind resource maps were validated with results from
previous low resolution studies and with observed mean
speeds from 10 met stations located along the coastlines
of both Nakhon Si Thammarat and Songkhla Provinces.
These comparisons have shown that the wind atlas
provides a good representation of the wind resource
throughout the territory of Nakhon Si Thammarat and
Songkhla provinces, Thailand. The technical power
potential and potential annual energy production that can
be generated from the wind in both Nakhon
Si Thammarat and Songkhla provinces are identified.
Results from the technical power potential at 80 m above
ground level (a.g.l.) for both Nakhon Si Thammarat and
Songkhla provinces show that a total of 1,374 MW of
wind farms, generating annually a total of 3.6 TWh of
energy, could be installed throughout the territory of
Nakhon Si Thammarat and Songkhla provinces. On the
other hand, a total of 407 MW of small wind turbines
(50 kW could be installed over the territory,
corresponding to an annual energy production of 1 TWh.
