Offshore wind

Great Southern Offshore Wind Farm

Macquarie’s Green Investment Group (GIG) is undertaking preliminary works to help identify a specific site for an offshore wind farm off the Bass Coast Shire in Gippsland, Victoria.

This work will involve talking to the community to ensure they are consulted, informed and heard.

GIG has been awarded a $A16.1 million contributory funding agreement from the Victorian Government’s Energy Innovation Fund to conduct preliminary work on a 1 GW wind farm. The funding will be provided subject to the project achieving certain milestones throughout its development process.

The development process will include undertaking environmental, social and technical studies.

Offshore wind benefits

While offshore wind is new technology in Australia, it is well established in countries such as the UK where it is a proven, clean and cost-competitive form of electricity generation.

Australia has a particular set of attributes, including an abundance of wind, that make it well-placed to harness this form of clean energy cost-effectively.  Offshore wind can play an important role in the overall mix of renewable energy sources that support Australia’s transition to a lower carbon economy.

Why Gippsland?

Gippsland benefits from wind speeds above 9m/s and marine conditions which suit the development of offshore wind.

With established offshore oil and gas and conventional energy industries there is potential to tap into existing skills and experience to support development, construction and operation of the project.

This includes health and safety professionals, geophysical and geotechnical engineers who may have a background in oil and gas or other offshore industries, electrical and mechanical engineers who have transferable skills relevant to the design, construction and operation of offshore wind farms and specialists engaged in the manufacturing industry (e.g. welders, coating specialists, pneumatic engineers etc).

Key facts

1,000 MW

Approximate estimated capacity

500,000+ homes

If realised, the project is estimated to meet the electricity needs of more than 500,000 Victorian households

885,909 cars removed

Avoiding 2,679 kt CO2e emissions per year is equivalent to taking 885,909 petrol cars off the road

Our capabilities

We have considerable international experience in developing offshore wind projects and a strong track record in the UK, Taiwan, South Korea and Japan.

We have supported around 50 per cent of the UK’s offshore wind capacity in operation and globally have a 35+ GW development pipeline of green projects, as well as 11+ GW of operational projects. We will bring this global expertise and track record to any projects we develop in Australia. 

Our parent company, Macquarie has worked with governments and clients to drive the energy transition and advance practical solutions to climate challenges. They have invested and arranged finance of more than $A63 billion into green energy since 2010.  They have built market leading capabilities in investing directly into climate mitigation and adaptation infrastructure and in supporting clients and portfolio companies to decarbonise their activities. 

Selected offshore wind activity

  • The UK, where we have supported almost 50 per cent of the existing offshore wind projects in operation. Recently we were awarded a lease for an up to 1.5 GW project alongside our project development partner TotalEnergies
  • Taiwan, where we are pioneering the offshore wind with the completion of the 128 MW Formosa 1, which was the first commercial offshore wind project. We have since established a further 2.5 GW pipeline of offshore wind projects that are in advanced development or construction
  • South Korea, where we have been developing projects since 2017.  Most recently, and in partnership with French energy company TotalEnergies, we are developing a 2.3 GW portfolio of floating offshore wind projects
  • Japan, where in partnership with Spanish utility Iberdrola, we are developing a 3.3 GW portfolio of six offshore wind projects.

Consultation activities

We have a careful and considered approach to engaging stakeholders and believe that project developers are responsible for consulting and informing stakeholders, addressing their queries and listening to their concerns.

We expect the project to be referred by the Victorian State and Commonwealth environmental authorities. This means that our project applications will need to be supported by both an Environmental Effects Statement (EES) and an Environmental Impact Statement (EIS). These statements will be considered by Government as part of the project approval process.

We estimate that it will take us 2-4 years to collect the relevant information to be included in the EES and EIS documentation and consultation with stakeholders is a key part of that process.

We will undertake a phased approach to consultation in order to capture information that will allow us to:

  • Fully scope the EES and EIS surveys and assessment methodology
  • Collect relevant data for presentation and analysis
  • Assess the potential effects and identify appropriate mitigation as required.

We will commence work in early 2022 in accordance with the program below:

Q1 2022:
Activity: Publish information on the project proposals and proposed scope of the EES and EIS
Objective: Invite stakeholders to review information and provide their feedback

Q2 2022:
Activity: Stakeholder consultation including community and fisheries events
Objective: Capture detailed feedback and local knowledge on project proposals

Q3 2022:
Activity: Report back on our findings and updates on our project proposals
Objective: Update on the status of project and the next steps

Q4 2022:
Activity: Commencement of environmental studies and monitoring campaign
Objective: Collect data to inform further analysis and consultation

Views of the local community are important to us. We are planning for a thorough and transparent period of engagement to enable the community to access as much information as possible:

  • Launch a dedicated project website
  • Issue regular project newsletters and email updates
  • Publish information letters
  • Hold stakeholder meetings
  • Have representatives attend community events

We look forward to engaging with you during this process and encourage you to contact us so that we can include you in our project updates.

Developing an offshore wind project

It takes over six years to develop an offshore wind farm and we're currently in the early stages.

The below shows the key phases of developing an offshore wind farm.
