Waipipi Wind Farm, Taranaki

As the market leader in Wind farm ‘Civil Balance of Plant’ (CBoP) projects in NZ, Higgins brought its extensive experience to deliver a highly successful CBoP contract for our valued customer Tilt Renewables.

Starting in October 2019, Waipipi generated first power with the first turbines brought online and exporting renewable electricity to the Transpower national electricity network in November 2020. The assembly and commissioning of the remaining turbines continues. All civil works have been completed apart from ongoing maintenance works. Restorative topsoiling of the completed construction areas and native planting along the Waipipi stream banks also continues.

Deion Campbell, CEO of Tilt Renewables says “It has been very satisfying to see the Higgins team in action again, working collaboratively with the other key workstreams to deliver a high quality CBoP scope, to our expectations, even given the unique challenges of the site and the wider impact of the NZ COVID response.  We are glad to have built on our long-term association with Higgins, reinforcing the trust that has been established to allow the contractual risk assignment to be such that ‘best for project’ is aimed for by everyone.”

Higgins leveraged the Fletcher supply chain for significant scope across the project including drainage materials from Humes, aggregates from Winstones, concrete from Firth, Golden Bay Cement, steel reinforcing from Fletcher Reo and ground improvements from Brian Perry Civil.

Melbourne-based Tilt Renewables expects Waipipi will generate about 455 GWh a year. That’s enough clean energy each year to power about 70,000 homes and save the emission of roughly 350,000 tonnes of carbon. This is the equivalent of removing about 70,000 cars from our roads.

Since commencing construction, the following works have been completed:
• Upgraded 4.5km of road between SH3 and the Dryden Road site entrance
• Established the site compound and site facilities
• Constructed an onsite access track network of more than 20km
• Completed the ground improvement at all 31 turbine locations
• Completed foundation construction at all 31 turbine locations
• Installation of the underground electrical cabling and fibre to all turbine sites
• Connecting of the underground electrical cabling to the assembled turbines
• Continued construction of the onsite substation including installation of the main transformer
• 31 turbines pre-assembled
• 20 turbines fully assembled
• 16 turbines operating
