ERG - How a wind farm works

Find out how the strength of the wind becomes energy that powers your activities. From nature to households.
A wind farm turns the wind's kinetic energy into mechanical energy, which in turn is used to produce electricity. The process is as fascinating as it is efficient. Plus, it is sustainable.

Cable duct

Links all turbines to the substation. Contains medium/high voltage electrical cables as well as the fibre optics cables needed for remote turbine control.

Substation

Contains all measurement and control instruments and the transformer which increases the voltage to 150 kV for connection to the national distribution network.

Blades

They are made of fibreglass on a wood and composite structure. An automatic system keeps them oriented towards the wind and optimises their inclination to best exploit kinetic energy.

Tower

It is anchored on a foundation of reinforced concrete (at times with piles).
A transformer is located inside it to increase the voltage to 30 kV alternating current.

Nacelle

Contains the speed multiplier, the electric generator (low voltage and direct current) and the blade position control systems. At times it also contains a low/medium voltage transformer.
