Hawkesdale Wind Farm Frequently Asked Questions

Renewable energy

What is renewable energy?

The Australian Renewable Energy Agency (ARENA) states that renewable energy is produced using natural resources that are constantly replaced and never run out. Just as there are many natural sources of energy, there are many renewable energy technologies including wind, solar, and hydro.

What is wind energy?

Wind energy is generated by harnessing the power of the wind through wind turbines. It is a great alternative to burning fossil fuels like coal, because wind energy does not produce greenhouse gas emissions.

How do wind farms generate energy?

Wind farms are groups of individual wind turbines that are connected to the electricity grid. Wind turbines use the energy of the wind to spin an electric generator, which produces electricity. Wind flows over the blades like air flowing over an aeroplane wing. This flow of air causes a difference in air pressure between the top and bottom of the blade, moving the blade and making the central rotor spin. The rotor drives a generator that produces energy to export to the grid.

Why is there increasing support of renewable energy generation from solar plants and wind farms?

Science based evidence has demonstrated that human-induced emissions of greenhouse gases is driving global warming. Fossil fuel burning (coal, oil, and natural gas) for energy consumption is the main source of these emissions.

In 2015, 196 nations agreed to a legally binding international treaty on climate change known as the Paris Agreement. Its goal is to limit global warming to well below 2, preferably to 1.5, degrees Celsius, compared to pre-industrial levels. In order to achieve this goal, countries across the world are transitioning their energy generation systems from fossil fuels to renewable energy such as wind and solar.

Can renewable energy technologies provide a reliable supply of electricity?

Renewable energy technologies generate electricity intermittently as the wind does not continuously blow, and the solar radiation intensity is not constant. Nevertheless, different ways have been developed to maintain a reliable supply of electricity from wind and solar energy generation. These include pairing wind farms with solar farms that generate electricity at different times and energy storage solutions, such as batteries.

How the wind farm will be connected to the grid?

It will be connected to the high voltage transmission network via new 132 kV, overhead transmission lines. A new 500/132 kV switchyard will be built adjacent to the existing 500 kV Tarrone terminal station and will include the necessary switchgear and a power transformer.

How much energy will be generated by the wind farm?

The Hawkesdale wind farm is designed to generate the energy needed to power the equivalent of 67,000 households.

How much greenhouse gases will the Hawkesdale wind farm displace?

The Hawkesdale wind farm will displace 333,000 tonnes of carbon dioxide annually that would have otherwise been emitted into the atmosphere through fossil fuel power generation.

Who are the main contractors involved in the construction and operation of the wind farm?

Vestas Australian Wind Technology is the turbine contractor appointed to supply and install the wind turbines, as well as the operations and maintenance contractor.

BMD Group and CPP Australia are the contractors for the civil and electrical works, respectively.

When will construction of the Hawkesdale wind farm commence, and when is it projected to conclude?

Construction commenced in 2023, with commercial operations beginning approximately 18 months after the start of construction. We will provide regular updates to the community via our newsletter and on this website.

Will the construction of the wind farm increase traffic on local roads?

During construction there will be a considerable increase in traffic on the local roads around the wind farm construction site. The traffic will be managed according to an endorsed Traffic Management Plan which will set out all requirements for all vehicle movements that are associated for the wind farm construction.

During the civil works there will be movements on the local roads by trucks with quarry materials. During the installation of the wind turbines components, there will also be movements from oversized heavy vehicles with those components, which will be under escort by pilot vehicles.

Our contractors will aim to impact the local roads as little as possible during the construction of the wind farm.

What type of construction activities should we expect for the wind farm?

During construction you will see different types of activities on site such as: stripping of topsoil with graders, excavating turbine foundations with excavators, pouring concrete foundations with concrete agitators and pumping trucks, delivering turbine components via semi-trailer trucks, erecting turbine components using a tonne crane, etc

Operation and decommissioning

When is the Hawkesdale wind farm expected to commence operations?

We expect that commercial operations at the Hawkesdale wind farm will commence approximately 18 months after the start of construction.

What is the expected lifetime of the Hawkesdale wind farm?

GPG Australia is an independent power producer, and we operate our renewable energy plants for the duration of their design life – which is approximately 30 years.

How will GPG manage the end-of-life decommissioning of the facility?

As a subsidiary of Spanish utility Naturgy Group, GPG is an experienced and responsible global developer and operator of power generation assets. GPG has a long-term owner vision and intends to operate the wind farms for the 30-year design life in partnership with the community.

How will GPG mitigate the impact of the Hawkesdale wind farm on the environment?

We are committed to minimising our environmental footprint and protecting the unique local environments in which we operate and have implemented multiple initiatives to achieve this goal.

These include:

  • Acoustic amenity – we have engaged Marshall Day Acoustics (MDA), one of the world’s largest and most respected acoustic consultancies, to conduct environmental noise assessments to ensure that the Hawkesdale wind farm is in compliance with the relevant standards.
  • Visual amenity – all residents within 4km of any turbine will have the option to receive off-site landscaping to reduce the visual impact of the turbines. The specific type of planting will be determined through mutual agreement between GPG Australia and the landowner. Further information can be found in the endorsed Off Site Landscaping Program available in the Relevant Documentation section on this website.
  • Flora and fauna – GPG is also committed to undertaking stringent monitoring program for operation, and a plan for response in relation to any threatened species, including mitigation.

Particular attention has been paid to Brolga, a species that is known to inhabit freshwater, vegetated wetlands on the Western Victorian Volcanic Plains of Victoria. Nesting and flocking sites of Brolgas are known in the region, but most are more than 20 kilometres away from the wind farm site.

How will GPG manage bushfire risks at the Hawkesdale wind farm?

GPG is committed to minimizing the risk of fires related to our wind farms. For example, the base of the wind turbines is separated from vegetation by a cleared gravel area which minimises risk of grass fires. The access tracks can allow more mobility of fire fighting vehicles and act as a fire break for grass fires.

GPG also collaborates with the Victorian Country Fire Authority (CFA) and will invite them to regularly visit the site so that they have a clear understanding of the facility. Additionally, two new water tanks will be provided for CFA-use-only, with capacity of 45,000L each.
