In a hydroelectric power plant, water is turned into electricity, which is carried to consumers along a transportation and distribution network.

The steps involve in production of electricity are as follows:

1. The dam raises the water level to create a vertical drop along the length.

2. The water takes on energy as it flows down and is carried with force to the turbine.

3. The generator converts water power into electricity. Figure below shows the generator unit.

4. The generator produces electricity through the movement of the rotor in the stator.

5. The electricity produced is integrated into the network.

6. At the outlet end of the power plant, the transformer increases the voltage; this reduces energy losses during transmission over long distances.

7. Electric power produced by the generator is transmitted to a transformer at the power plant outlet.
