Project Overview

The SEC Delburn Wind Farm is a 205 MW, 33-turbine onshore wind farm located in the Strzelecki Ranges of South Gippsland, Victoria. On 23 December 2025, the State Electricity Commission of Victoria (SEC) announced its 100 percent acquisition of the Delburn Wind Farm for approximately AUD 650 million. 

The acquisition confirms Vestas as the turbine supplier (33 × V162-6.2 MW turbines) and OSMI Australia's continued role as delivery partner. This made Delburn Victoria's first 100 percent publicly owned wind generation project on a utility scale. 

The 205 MW facility will generate enough electricity to power over 130,000 Victorian homes. The construction begins in April 2026, with a completion target expected by 2028. SEC's anticipated capital expenditure for construction is AUD 600–700 million.

Delburn Wind Farm Location

The Delburn Wind Farm is located in the Strzelecki Ranges of South Gippsland, Victoria. It is situated within the HVP Plantations' Thorpdale Tree Farm just south of the Latrobe Valley. 

The Latrobe Valley is the centre of Victoria's brown coal power generation, home to the Hazelwood, Yallourn, and Loy Yang power stations.

The siting of a major new wind farm overlooking the former Hazelwood site is widely understood as a deliberate signal of the region's transition from coal to renewables.

Project Background

OSMI Australia first proposed the Delburn Wind Farm in 2019. The proposal immediately attracted both support and opposition. Residents raised concerns about noise levels, visual impact on the rural landscape, and bushfire risk given the wind farm's location within a commercial pine plantation, a land use type considered to carry elevated fire risk in Victoria's climate. 

The project underwent multiple legal challenges through Victoria's planning appeals system between 2019 and 2023, addressing the noise, visual amenity, and bushfire concerns raised by objectors. The project passed its final legal hurdle in 2023, clearing the path for development consent.

The project struggled to finalise construction financing and contracts amid the broader headwinds facing the Australian renewable energy sector at the time, including supply chain costs, interest rate increases, and grid connection queue delays.

The State Electricity Commission of Victoria, re-established by the Andrews Labor Government in 2023 as a publicly owned renewable energy company, identified Delburn as an opportunity to deliver its first major generation asset. The Delburn acquisition, announced on 23 December 2025, marked SEC's first entry into ownership of utility-scale wind generation. 

Following the acquisition, the SEC confirmed Vestas as the turbine supplier and OSMI Australia's continuation as the delivery partner, providing continuity of community relationships and regulatory compliance knowledge built up since 2019. Delta Group was engaged to support construction services.

Delburn Wind Farm Current Status & Completion Date

As of June 2026, the Delburn Wind Farm is in the construction phase. The work began in April 2026 after the State Electricity Commission took over the project in late 2025. The project is expected to become fully operational by 2028.

Project Scope

The following is the project scope of the Delburn Wind Farm

• Capacity & Infrastructure: The wind farm comprises 33 wind turbines with a total generation capacity of up to 205 MW, producing approximately 640,000 MWh of renewable energy annually.
  

• Energy Output: The wind farm is expected to power over 130,000 homes annually and contribute to reducing carbon emissions. 
  

• Turbine Installation: A total of 33 turbines, each of which will generate 6.2 MW. The blade tip height will be 247 metres and the hub height up to 166 metres above ground level. The lower rotor swept path will be 85 metres above foundation level.
  

• Associated Infrastructure: It includes water tanks for firefighting, site compounds, & connection to the electricity grid.
  

• Grid Connection: The project includes associated civil, electrical, and balance-of-plant works needed for construction and grid connection. 

Project Timeline

Benefits

The following are the benefits of the project: 

• Clean Energy Generation: The wind farm produces up to 205 MW of renewable energy, generating approximately 640,000 MWh annually, enough to power over 130,000 homes. 
  

• Job Creation: Generates over 300 full-time equivalent jobs during the construction phase (2026–2028) and additional ongoing roles during 30–35 years of operation.
  

• Community and Neighbour Benefits: Delivers more than AUD 22 million in neighbour and community benefit sharing programs over the project’s life, including local grants and initiatives.
  

• Public Ownership Milestone: Victoria’s first 100% publicly owned utility-scale wind farm, helping the State Electricity Commission (SEC) supply renewable energy to public services, schools, hospitals, and more.
  

• Environmental Integration: A forest-based project situated in an existing plantation, with technical assessments addressing biodiversity, bushfire risk, visual impact, and other factors.

Conclusion

The Delburn Wind Farm, a 205 MW capacity project, is a major renewable energy project that boosts the clean energy generation of Victoria. This under-construction project, with strong employment potential and long-term community benefits, plays a pivotal role in Victoria’s future energy. 

Upon completion, the wind farm will provide large-scale wind power to the main grid, help reduce emissions, and support the state’s transition away from coal-heavy generation in the Latrobe Valley. 

Overall, Delburn Wind Farm represents a long-term investment in cleaner energy, regional growth, and Victoria’s future power needs. Beyond power generation, it signals the Latrobe Valley’s shift from coal to renewables and establishes a model for publicly owned clean energy infrastructure.
