Recently repaired sections of State Highway 5 are used to transport turbines to Meridian Energy’s Harabackee wind farm. New Zealand transport agency, Waka Kotahi NZ Transport Agency, has confirmed that complete road closures are not expected and that the completed road in Esk Forest will greatly ease the transport process.
Despite the challenges of moving large structures, Waka Kotahi said there were no road closures during the turbines’ transport in July and no further closures are expected. However, traffic control will be implemented at times and details will be confirmed.
Meridian Energy has released a video showing the progress of the $440 million project, with the first parts of 41 turbines already shipping. Deliveries will take place six days a week and traffic is expected to be completed by the end of January.
The transportation process involves moving two large loads each morning, the blades or tower sections. Additionally, smaller components are delivered throughout the day, some of which are heavier, wider loads.
One of the main challenges facing the project was a landslide on the section of the track between Te Pohue and Glengarry that was damaged during Cyclone Gabriel. A bypass has been used for other vehicles, but the length of the trucks hauling the turbines precluded its use. The road should be restored to its original condition so that traffic can continue.
Waka Kotahi expects the newly constructed road in Esk Forest to be fully completed in the coming weeks. About 6,500 tons of materials, mostly aggregate, have been used to rebuild the area.
Harabaki Wind Farm will become New Zealand’s second largest wind farm. It is expected to start power generation in October 2023 and reach full power generation capacity in September 2024. The 41 turbines will generate enough electricity to power about 70,000 homes.
