The cost of building the wind farm was approximately $865 000 in 1987. Over the 13 years of its life the generators saved about 3 million litres of fuel oil being burnt in the old power station
The concrete bases where 6 x 6 x 1 metre deep and weighed 90 tonnes.
Each of the towers was made with four tapered octagonal sections and were 22 metres high when assembled. These sections fitted into one another without any welding of the joints. Continual pressure from gravity and movement forced the tapered sections even further together. One complete unit is left on site with another mini tower and head placed near the Esperance Museum. A section of a tower without the head is in the car park near the remaining unit.
The wind turbines, with 3 blades of 8 metres, require a minimum speed of 14 km/ h before electricity was produced. At 45 km/h the generators produced maximum output. In very strong winds centrifugal forces cause the tips of the blades turn at right at angles to the blades thus reducing the speed of the turbines. Slewing motors would turn the head to make sure it faced the wind.
In an emergency a large disk brake between the gear box and generator stops the blades from turning. The operation of the turbines was automatic.
Each generator was monitored for performance from Perth. Typical data was wind speed wind direction, electricity generated and any faults.
