IELTS Writing Task 1: Process Writing with Sample Answer
The diagram shows how electricity is generated by a hydroelectric
dam.
Write a 150-word report for a university lecturer explaining how
the process works.
The diagram depicts and elaborates
the process of electricity generation with help of Hydro project.
The hydroelectric power
generation process involves construction of a dam to store water in the reservoir;
and a powerhouse to house generation equipment. The water from dam’s lake is
channelized to the turbine through intake and a narrow channel called Pen stock.
The water channels are usually narrow passages which are designed to add speed
and force to the flow of water. The force of water is, in turn, used to turn
the turbine which subsequently runs the generator unit, connected to it, in the
powerhouse. The water that passes through channel; and turns the turbine is
routed into the river through a second tunnel.
The electricity resulting
from such process is transmitted to distant locations with the help of long distance
transmission lines.

Hydroelectric electricity
generation process involves four phases, i.e. storage in reservoir; directing
towards the turbine through tunnel; electricity generation through generator;
release of water into the river; and transmitting electricity through power lines.
