A hydroelectric power plant coverts the potential energy oh the water upstream to the kinetic energy in flowing or falling water and finally into electrical energy. hydroelectric power can be generated on a small scale with a run-of-river installation, e.g., Pal Mun dam in Ubon Ratchathani provinces, which uses naturally flowing river water to turn one or more turbines, or on a large scale eith hydroelectric dams, such as Bhumibol dam in Tak province
