Community Information Session (Online Webinar)

Thank you to those who attended our recent online webinar. Your participation and questions helped make it an informative and engaging session.

What We Shared

During the webinar, we provided an update on the Marmadua Energy Park, including the latest turbine layout plans and a visual assessment of how these turbines may appear within the landscape. We also discussed our environmental considerations, the status of the Project’s approval process, and the range of potential benefits the project could bring to the local community—such as long-term renewable energy supply, potential employment opportunities, and contributions to the region’s sustainable growth.

Community Engagement in 2025

We understand how important it is for you to not only learn more about the proposed Marmadua Energy Park, but also to have opportunities to provide input on aspects of the Project. In early 2025, we will be back out in the community to continue our engagement as the project progresses through the approvals process, and to listen to your valuable feedback. We look forward to these discussions and appreciate your continued engagement.

In the meantime, if you have any questions or would like more information, please feel free to reach out to via:

Frequently Asked Questions

The Project

Cubico Sustainable Investments is one of the world’s largest privately-owned renewable energy companies, working in 12 countries across four continents.

We have offices in Sydney, Melbourne and Brisbane. Our Australian projects include the Wambo Energy Hub in Jandowae, Queensland and the Delburn Wind Farm in Gippsland, Victoria, alongside many early-stage developments across both states.

For further information about Cubico, visit our website

Cubico Sustainable Investments is a developer, owner and operator of renewable energy projects worldwide. We have the financial backing to develop the wind farm from concept, through construction and into operation. We are here for the long run to develop great projects that can join our portfolio of operating assets.

Many factors are considered in selecting the right site for a wind farm. This site has quality wind resource, willing landowners, suitable grid connection, limited environmental and cultural heritage constraints and community impact.

The project is for a wind farm with up to 110 turbines. It is to be built north of Kumbarilla State Forest, about 22 km from Tara and 37 km from Dalby, in the Western Downs Regional Council local government area.  

The project is projected to generate 700MW in wind energy, which would power approximately 480,000 homes.

Across our global portfolio of projects, Cubico prioritises environmental and social responsibility. This means that we strive to limit our impact to flora and fauna wherever possible.

Our team is actively working with environmental experts to minimise or offset any adverse impacts to the environment, including flora, fauna, water quality, and soil health. We are committed to implementing a comprehensive plan that adheres to environmental best practices.

The project is subject to stringent environmental planning assessments and controls to ensure any potential impacts to the local ecosystem are carefully considered.

Community

The Marmadua Energy Park will deliver a range of benefits for the local and broader community, including:

  • investment in local and regional businesses through procurement opportunities
  • local employment opportunities through the creation of 480 construction jobs, and subsequent 35-year operations jobs.

  • investment in the community through the Community Benefits Fund from the start of construction.

A Community Benefits Fund is a pool of money set aside by Marmadua Energy Park to support projects and initiatives run by the local community for the local community.

Further information about the Fund, including how to apply, will be released in due course. 

Wind Farms

Wind turbines capture wind energy swept by their blades. The spinning blades drive a generator that produces electricity for export into the national grid.

Technological advances mean wind turbines are now larger and more efficient. Intelligent technology is also increasingly being used to improve efficiencies. Rotor diameters and hub heights have been increased to capture more wind and produce more energy per turbine. These advances in technology mean that fewer turbines are needed to produce the same amount of energy.

Along with solar, wind energy is one of Australia’s main sources of renewable energy. Renewable energy generated enough electricity in 2020 to meet more than 35% of Australia’s electricity. Almost 10% of this was from wind.

Wind farms are expected to have an operational life of 30 years, during which time they are carefully managed and maintained. When wind turbines reach the end of their practical life, they are decommissioned and removed. The wind farm owner is responsible for deconstruction, removal and remediation of the site.

Recycling of wind turbines is a key consideration for the industry. Approximately 85% of the materials including steel towers, copper cabling and aluminium components are readily recycled in steelworks and foundries. There are also now a variety of ways of dealing with the blades, including:

  • Repurposing – blades can be used as support structures for bridges, making bicycle shelters, and roofing.
  • Recycling – using the ground up fibreglass in cement and other manufacturing processes.

Research is ongoing into designing blades using materials such as thermoplastic resin or carbon fibre instead of fibreglass so that they can be more readily recycled into higher-value end products.

Battery Energy Storage Systems (BESS)

Battery energy storage is a system that stores excess electricity for later use.

It's like a giant rechargeable battery for Australia. When we are producing more energy than we are using (like on sunny days), the excess is stored. When we need more than we are producing (cloudy days with less wind), the stored energy is released into the grid.

BESS helps stabilize the electricity grid by balancing supply and demand. This can lead to more reliable power, reduced energy costs, and increased use of renewable energy sources that are cheaper, safer, and more environmentally friendly. 

The most common type of battery used in large-scale energy storage is lithium-ion, similar to those in electric vehicles. These batteries are efficient and long-lasting.

For more information, check out the Battery Storage page from the Australian Renewable Energy Agency (ARENA) website.

The BESS system typically consists of large battery containers housed in a secure enclosure. The appearance can vary depending on the specific technology and design.

Cubico designs BESS systems with safety as a top priority. Our systems follow stringent regulations and incorporate advanced safety features that are rigorously tested to ensure the protection of people and the environment.
