Hydro Dam Explanation

WALT write an explanation of how a Hydro-power station works







A hydro-dam is a amazing structure that makes electricity from water!


Firstly you build a dam to block the river.Water then builds up behind the dam.This is called the reservoir.

It then goes through the intake and all the water rushes down  the penstock. Then it goes to the turbine and the water goes around it and makes the turbine spin.

This makes electricity which is stored in the  generator . It goes out to the power lines and it travels to peoples houses.

A dam is a very helpful thing that gives you lots of electricity and it is a very big structure.Hydropower is also renewable.
