All together, the turbines create enough electricity each year to power 136,573 WA homes.
Wind power in WA
The wind turbine hubs sit on tall towers, 65m from the ground. With 35m rotor blades, each turbine stands 100m tall and covers an area of 3,850 square metres as it spins.
That’s 18m taller than the Bell Tower, and as wide as half a soccer pitch!
When the wind blows
The rotor blades will turn and start to generate electricity with wind speeds as little as 7 km/hr.
Blades will only stop turning, as a safety precaution, if it blows a gale over 130 km/hr.
In Albany, the wind is almost always just right. On average, there are only 7 days in a year when the wind is not strong enough to power the turbines.
Inside the turbine
As the wind blows, the rotor blades turn a main shaft at about 15 revolutions per minute (RPM). This isn’t, however, fast enough to generate electricity.
A series of gears increases the speed to around 1,800 RPM on a high-speed shaft, and electricity is generated from the kinetic energy.
From turbine to town
Electricity is sent down the turbine, where a transformer increases the voltage so it can be sent through the grid to power WA homes and businesses.
