Wind energy is a natural phenomenon caused by the difference in temperature, Barometric pressure and the force of the earth's rotation. These are the factors that cause the wind speed and wind power that makes objects blown-flying. Wind is clean and environmentally friendly energy. It is considered as an alternative energy that can be utilized. With the advancement of technology, humans have developed wind turbine design since the days of ancient Egypt by using knowledge of aerodynamics and various engineering principles to maximize the wind energy, especially to generate electricity.
For the use of wind energy in Thailand, the wind power should not be less than the annual average of Class 3 which is 6.4 to 7.0 m/s or 300-400 kW/sq.m. at 50 m. height so that the installation of wind turbines can be done. From the exploration for the sites with such wind speeds, we found the areas around the east coast. starting from Nakhon Si Thammarat, Songkhla and Pattani and at Doi Inthanon, Chiang Mai which is influenced by the northeast monsoon from November to end of March. The installation of wind turbines must consider other factors as well in addition to the speed of the wind such as the topography should be the open plain without any obstacle and steady wind speed.
IFEC has studied the project and invested in Green Growth Co., Ltd. (GG), which will engage in production and distribution of 3-blade wind power turbine of Permanent Magnet Direct Drive system (PMDD). Dr. Sumet Suthapacti, the Chairman of Green Growth has studied the wind power and business as well as developed the wind turbine at Se Ju Island, South Korea ที่at 33 MW which took 5-6 years to develop the site for the project and at present this area is of high potential for more development of wind turbines which helps the Company to prepare the blueprints for wind turbines installation and produce the electricity as planned. The project at Pak Phra, Pak Phanang, Nakhon Si Thammarat is the first to have a capacity of 10,000 kilowatts. The project was designed and developed as the wind park, a prototype of the park as the resource for renewable energy study to local people. This indicates that the renewable energy from nature can coexist with human in perfect harmony. The project is currently under construction and tool installation from Goldwind. It is planned to begin selling electricity to the Provincial Electricity Authority on May 1, 2015 with a capacity of 10 MW. Regarding the ongoing projects in Songkhla, IFEC Group is prepared to further develop for the benefit to the society and return to the environment as well.
