Meanwhile, electricity is generated in the powerhouse.Initially, water flows through an intake to a chamber called penstock. After that, water follows the current and applies pressure to the turbine, forcing it to rotate in a circular movement. At the next stage, the turbine begins to creates energy. Energy is then supplied to the generator attached to the turbine. Following this, the generator converts energy into electricity in the powerhouse, and power lines are in charge of distributing electricity to distant areas through a machine.It is interesting to note that the dam is constructed on the river, and the bulk of the procedure happens underground. Besides, abundant water follows its current and ends up in the river. Then, it is renewable, and electricity is automatically generated again with the hydroelectric dam.
