Yandin 330kV Wind Farm Line & Terminal

Overview

The Yandin Wind Farm is located approx. 175km north of Perth. Compromising 51 4.2MW Turbines,the Wind Farm connects to Western Power’s 330kV Electricity Network via a new 10km Transmission Line and Terminal Station which Genus was tasked to design and construct.

The area lays claim to some of the strongest and most consistent winds in the country. With a capacity factor of around 50 per cent, Yandin will power the equivalent of approximately 200,000 households across Western Australia each year.

The Terminal consists of over 150,000 tonnes of sand fill and 1000 cubic metres of concrete. Tying into the existing Neerabup to Three Springs Transmission Line, the location of the Terminal has been carefully thought out to ensure minimal impact on the environment, utilising existing cleared areas. Genus was able to work with Western Power to create a very expedited schedule to ensure we met the tight deadlines. 

This project demonstrates how Genus are integrating some of Western Australia’s most significant Wind Farm Infrastructure.

Outcome

Genus have successfully completed all stages of the works to date with only the site surfacing aspect of the works remaining. We completed the full scope without a major incident which is a credit to our dedicated teams.

The Transmission Line – which is 10km long – had to traverse over several landowners, including the Iluka Mineral Sand Mine. Genus designed the route in a such a way to minimise the impact to the mine to ensure the ore bodies were avoided. Black Cockatoos were also prevalent in the area and through careful surveys we ensured there was no impact on their habitat.

The wind farm now connects to Western Power’s 330 kV electricity South West Interconnected System network.
