It is known that the dispersion of pollutants from the sources are mainly depends on wind velocity and direction of the wind. The movement of pollutants, the spread of pollutants, and the dilution of pollutants are all depends on the wind. To measure the wind in various altitudes using meteorological stations in order to obtain a higher resolution data will make a lot of spending budget and numbers of maintenance. This is the reason why installing numerous meteorological station in the area of interests are unappropriated.
For this reason, the dynamic numerical meteorological model is one of the most powerful tools to counter those obstacles. According to EGAT’s policy in prevention and protection of the local environment around EGAT’s power plant, EGAT proactively formed the small working group to research on the wind data forecasting project back on 2014. The forecasting originally using three-dimensional meteorological model named “Regional Atmospheric Modeling System” for wind data forecast, which included planetary boundary layer (PBL), wind power, wind field and temperature for Mae Moh power plant, EGAT’s largest lignite power plant in Lampang province and also for Bang Pakong power plant. The project was successfully implemented and available for internal utilization since 2015. After months of operation, the project was continuously developed to some others locations as well. Krabi power plant and the location for The-pha power plant project has been developed which also included the vessel routes for coal transportation of both locations.
However, EGAT's continued our commitment to develop more forecasting model to other EGAT’s locations. EGAT will constantly enhance our project in developing “Air Quality Forecasting System” to serve the community. This is the prove that EGAT is not only focus on our routine but also, we are ready to move forward with the focus on community and environmental consciousness to the delight of Thai people thoroughly and evenly.
