The diagram compares the process by which electricity is generated in two types of hydroelectric power stations. Overall, electricity produced by a traditional hydroelectric plant is produced in three stages, as opposed to in five stages at a run-of-river hydroelectric plant. In a traditional hydroelectric power plant, river water rises behind a dam until it is sufficiently high enough to enter an intake pipe near the top. Once it enters, the water flows down into a much lower turbine chamber whereupon it causes the machine's blades to rotate, thus generating electricity. This power is then sent via transmission lines to customer's homes. On the other hand, in a run-of-river hydroelectric plant, the natural flow of the water running downhill is harnessed to turn the turbine blades. Initially, water is channeled away from the water's primary path down a pipe into a turbine building further down the hill. Upon entering the building, the water causes turbine blades to rotate which in turn spins a generator that produces electricity. this power is then conducted by transmission lines above the plant to where it is needed. Surplus water then exits the plant and rejoins the river to resume its original course.
