The first tower has gone up at ACCIONA’s Mt Gellibrand wind farm in Victoria, representing a major construction milestone for the project.
Comprising three base sections lifted by a 500-tonne crane and then bolted together, the 61-metre tower was erected on a single day by a team of skilled personnel with extensive expertise.
Over the next seven months, 44 steel towers in total will be installed at the site. After each one is erected a separate crew adds the 26-metre top section and the nacelle, which houses the gear box, drive train and generator.
The final steps involve attaching the hub to the nacelle, and then the three 60-metre blades to the hub. At their highest point the blades will reach almost 150 metres into the air.
Each blade weighs approximately 17.5 tonnes, while the four tower sections collectively tip the scales at 220 tonnes. Over the complete installation process, more than 18,000 tonnes of turbine infrastructure will be moved into place.
Over 150 people have been involved in construction at the site, including several local contractors. Around $10 million will be spent directly in the local area over the course of the project.
ACCIONA Energy Australia Managing Director Brett Wickham said: “Building a wind farm is a significant undertaking, and after so much preparation we’re pleased to see the towers going up. Our team is working hard, and our local subcontractors continue to contribute their valuable skills to this project – we couldn’t do it without them, and we thank the community for their ongoing support.”
