Potential of Hydroelectricity from The Irrigation System Reservoirs in Phatthalung Province
Main Article Content
Abstract
In this study, the hydropower potential was analyzed for the irrigation system with 8 weirs and 4 reservoirs in Phatthalung province. The stream flow secondary data from the information data of royal irrigation department, the physical survey and water current speed were collected in which the seasoning of the study water reservoirs. The result showed that the irrigation systems have the hydropower of the stable water flow rate equal to 1,720 kW, with 860 kW of the hydropower generation and 6.8 GWh of the electrical energy per year. The hydropower potential classified as 3 sizes, Mini Hydropower (0.1 – 1.0 MW), Micro Hydropower (10 – 100 kW) and Pico Hydropower (< 10 kW) have identified 3 sites, 8 sites and 1 site, respectively, with the total hydropower of 509 kW, 343 kW and 8 kW, respectively.
