FAQs

About wind power

How much power will the wind farm generate?
Granville Harbour Wind Farm will comprise 31 turbines with a 112 megawatt capacity in total – that’s enough clean energy to power around 46,000 average Australian homes.
How do wind turbines work?
The blades of the wind turbine are rotated by the wind. As the blades turn, they rotate the main shaft of the turbine which is connected to an electrical generator. Through gearboxes, the generator converts the spinning movement (known as kinetic energy) into electricity.

The wind turbines are grouped together and linked to the wind farm substation using underground cables.

How will the wind farm be connected to the grid?
A new overhead electrical transmission line approximately 11 kilometres long will be constructed from the wind farm substation parallel to an existing power distribution line along Heemskirk Road and Wilson Road to the Reece Power Station connecting the wind farm to the existing grid.
How fast does the wind need to be blowing for the turbines to operate?
Each wind turbine operates independently.  Sensors located on each turbine consistently assess wind speed and direction and manoeuvre to make best use of available wind resources.

Turbines will start operating at speeds of approximately 18km per hour. To protect equipment from damage, turbines will stop operating and turn out of the wind when wind speeds exceed 90km per hour.

Are wind farms noisy?
No. Wind turbines are highly efficient in creating energy using simple mechanical components and the power of the wind.  Blades are aerodynamically designed to move through the air with as little resistance as possible. This means that turbines are very quiet, particularly when compared to the noise of the wind itself.

About the project

Who is developing the project?

Granville Harbour Wind Farm is being developed and constructed by Palisade Investment Partners, an independent Australian-based infrastructure manager with experience in clean energy projects.

The project is being financed by Palisade’s Renewable Energy Fund (50.2%) and leading international infrastructure investor, John Laing (49.8%).

Granville Harbour Operations Pty Ltd (GHO) will manage the project on behalf of Palisade Investment Partners.

When will the wind farm start generating energy?
Granville Harbour Wind Farm is expected to be operational and start generating electricity by late 2019.
Will there be local employment or business opportunities?
The Granville Harbour wind farm is expected to create around 200 temporary jobs during construction and ten permanent jobs. During the construction period there will also be flow-on benefits for the local economy, particularly the nearby town of Zeehan and its local businesses.
Are you engaging with the local community?
We will seek to engage with neighbours, stakeholders and the local community throughout construction to ensure project benefits are communicated and potential construction impacts are minimised.

Should you have a query, or wish to know more, please contact us.

Can members of the public access the site?
No. Granville Farm is private property and therefore not accessible to the public.
Will Granville Farm continue to operate as a beef cattle farm?
Yes, Granville Farm will continue to graze cattle on its 1200 hectares of prime pastures and continue to produce some of Australia’s highest quality grass fed beef.
What will happen at the end of the project?
Granville Harbour Wind Farm is expected to operate for 20 years.  After that time, the asset will either be refurbished and updated or decommissioned, and the site returned to its original state.

Environment

Will the wind farm be visible to local residents?
The visual impact of the wind farm has been assessed by both the EPA and the West Coast Council in approving this development. While wind turbines will be visible from locations around Granville Farm, the overall visual impact has been assessed as acceptable based on the level it is likely to impact the surrounding visual landscape. Wind turbines will not be built within coastal areas.
Will significant amounts of vegetation be removed?
No – protected native vegetation will be largely protected during construction of the wind farm. Management plans will also be in place to ensure native vegetation is protected during operations, once the wind farm is complete.
What about protected species?
Two fauna species listed under the Tasmanian Threatened Species Protection Act 1995 (TSPA) and Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), the Tasmanian Devil and the Spotted Tailed Quoll, have suitable habitat within or adjacent to the proposed project area. However, field surveys have found no den sites for either species.

Bird surveys of the site have also been conducted over the decades. These have found that the site supports very few birds of prey or waterbirds, groups considered more vulnerable than others to collision with operating turbines, which may be due to the modified agricultural landscape of the site.

When the wind farm is operational monitoring for bird and bat collisions with wind turbines will be undertaken to continually assess impact on local species.

Will there be impacts on nearby coastal areas?
No, the development is not proposed to be constructed on or near coastal dunes or beaches.
What will you do to manage traffic impacts?
The wind farm will result in an increase in traffic volume for the duration of construction. In recognition of the risks this may pose to private vehicles and native wildlife, measures will be implemented to reduce these risks such as buses for the workforce and work hours on site being restricted.

Transport of large items to site will follow an approved transport route from the Port of Burnie to site and notifications of potential disruptions will be advised where possible.

Will the wind farm increase bushfire risks?
Project management will work closely with local emergency services to properly assess bushfire risks and management strategies.  Mitigation measures at the wind farm site – such as adequate and properly maintained fire fighting equipment – will be provided.

The transmission line will have a full-width cleared easement to ensure trees do not contact the line and cause outages or the risk of ignition.

Do you plan to expand the project in the future?
Granville Harbour Wind Farm has no plans for future expansion and considers the proposed development appropriate for the site at this stage.
How will you manage waste?
Where possible, waste materials will be recycled or re-used, such as cleared timber repurposed for firewood. Waste disposed of offsite will be undertaken in accordance with West Coast Council and legislative requirements.
