BlueFloat, Energy Estate and Elemental Group unveil New Zealand wind plans

The consortium of BlueFloat Energy, Energy Estate and Elemental Group unveiled plans to build an offshore wind farm 22 kilometres off the coast of South Taranaki, New Zealand. The proposed project is the first of four offshore wind projects planned by the consortium in Aotearoa with the potential to add up to 5GW of new clean energy generation.

The South Taranaki project is designed to be a ~900 MW offshore wind development using fixed bottom technology located to the west of Beach Energy’s Kupe platform in the South Taranaki Bight. The proposed site was identified as offering potential in the Offshore Wind Discussion Paper published by Venture Taranaki in April 2020, due to the site’s characteristics and environmental conditions. That study identified an area large enough for several offshore wind farms to be built by different developers.

The site is close to the only deep-water port on the west coast, Port Taranaki in New Plymouth, allowing access to build, import and transport materials required for construction and to service the specialised vessels required for installation and maintenance.

The site includes a relatively flat sea floor with a water depth of less than 50 metres suitable for fixed-bottom turbines. It is in close proximity to local industrial facilities where electricity can be converted to green hydrogen for use in transport fuels or as feedstock for green chemicals like urea, ammonia and methanol. Furthermore, it has potential for floating wind farms to be developed in subsequent phases alongside the initial phase of fixed bottom projects.

The proposed site covers approximately 230 square kilometres and sits beyond the 12-mile nautical zone and outside the boundaries of the West Coast North Island Marine Mammal Sanctuary and the sensitive eco-system of the Patea Reef.

Partnerships Director for the JV Justine Gilliland said “Offshore Wind will be an important part of the future energy mix in Aotearoa and will help the country meet its net zero targets. South Taranaki is an obvious choice as it has a best-in-class wind resource and a skilled local workforce with decades of experience working offshore. We are committed to developing the industry sustainably and are already engaging with environmental and local experts to understand how we can mitigate potential risks to marine mammals, seabirds and the coastal environment.”

The consortium stated it is advocating for an all of industry approach, including supply chain and logistics, where developers will collaborate to create an offshore wind industry – not just projects. This will mean working strategically with iwi, government, regulators, Transpower, businesses, and local communities to create an industry that benefits all stakeholders.

In August the JV announced that Beach Energy is facilitating the placement of a LiDAR (Light Detection and Ranging system) on their Kupe platform and to share the data with several offshore wind developers. The LiDAR measures a number of key data points such as wind speed, direction and consistency that will help inform the JV’s development plans.

Simon Currie, Co-founder of Energy Estate said: “We want to be upfront and show coastal communities and users of the sea what our projects will look like. For this reason, we have prioritised preparing and releasing accurate visual simulations of our projects in New Zealand. The process to create the 3D simulation involves the use of panoramic photographs (taken by a local photographer) from a number of locations, trigonometry, data points and digital technology. The output is a realistic and a scientifically rigorous visual representation of an offshore wind project.”

District Mayor, Phil Nixon, commented: “Offshore wind supports our transition to a lower emissions economy, and with the potential for partnerships with mana whenua and the development of initiatives such as a research and innovation hub will help ensure South Taranaki remains Aotearoa, New Zealand’s (sustainable) energy generator for the future.”

The project is estimated to create at least 600 jobs in construction, operations and maintenance and to create further employment opportunities throughout the supply chain. The electricity generated from 900 MW is the equivalent of powering nearly 440,000 homes.

Commenting on the announcement, Anne Probert, Venture Taranaki GM Regional Investment said: “With strategic foresight and through our Taranaki 2050 and Tapuae Roa work, we identified the potential for offshore wind in Taranaki. Leveraging our energy expertise and partnerships, we have been able to catalyse the offshore wind opportunity, releasing the pioneering offshore wind report in 2020, and the subsequent offshore wind energy forums and we are now seeing it move moving closer to realisation. Offshore wind will be a considerable future resource to provide large quantities of low-emissions energy while utilising many of the complementary skills and resources in Taranaki that service the existing energy sector in New Zealand.”

The project is currently in the feasibility stage, but the partnership believes that construction could commence before 2030. The lifecycle for offshore wind farms is around 30 years at which point they would be decommissioned or re-purposed offering decades of meaningful employment opportunities for the region’s workforce.
