The Delburn Wind Farm is proposed to be built in an area that is recognised as having an existing fire risk. An extensive Bush Fire Risk and Mitigation Report has been prepared by Fire Risk Consultants to assess the risk that may result if the proposed wind farm goes ahead. The risk assessment considers both risks to the surrounding community, as well as the risk to the wind farm itself arising from its location within the plantation.

We have held preliminary discussions with CFA in relation to the project. As part of our planning permit application process CFA will be a referral authority, which means they will review our assessment of the fire risk and may require conditions to be included on any permit that may be granted.


Preliminary Bushfire Risk Assessment

Reducing Fire Risk

The risk assessment concluded that the Delburn Wind Farm proposal would not increase the bush fire risk in the landscape if a number of recommendations included in the report were adopted during development, construction and operation. To meet these recommendations, we have incorporated specific design measures into the proposal to reduce bush fire risk, including the following:

  • The transmission network from all turbines to the terminal station and the connection to the existing 220V network places all powerlines underground, consistent with the recommendations of the Victorian Bushfires Royal Commission, which identified powerline failures during severe weather as a cause of several of the Black Saturday fires.
  • Each turbine will be equipped with built-in fire suppression and alarm systems.
  • All turbines will be fitted with lightning conductors, reducing the likelihood of fire starts from ground strikes.

Other areas where we can work to reduce the risk of fires are through associated infrastructure development and management collaboration with HVP during the operational life of the project. These areas include the following:

  • Building an enhanced road and track network, which can increase accessibility and shorten response times in event of a fire, and which also increases the number and effectiveness of roads as fire breaks.
  • The increased workforce numbers operating in the forest and remote cameras installed on all turbines should increase the likelihood of early detection of any fire starts, and also provide an increased deterrent against arson.
  • There will be an increase in the number of personnel within the forest trained in and equipped for fire suppression.
  • The provision additional static water supply at strategic locations throughout the project area.
  • Opportunities to enhance planning and annual exercising for bush fire response with HVP.

Aerial Firefighting

The risk assessment considered aerial firefighting in line with guidance provided by the Australasian Fire and Emergency Service Authorities Council (AFAC) and concluded that wind turbines are not expected to pose an unacceptable risk to aerial firefighting operations. Fire suppression aircraft operate under ‘visual flight rules’, and so are only used in areas where there is no smoke. As part of routine procedures, Pilots and Air Operations Managers must always assess risk on a case-by-case basis, and turbine towers will be treated in the same way as any other tall obstacle.

CFA guidelines require turbines to be at least 300m apart to allow adequate distance for aircraft to operate around a wind-energy facility. The minimum spacing of our turbines is 600m, and in many cases considerably more than this.

In the event of a fire, the turbines would be shut off and parked in the Y position to reduce the risks to aircraft operations from wake turbulence and moving blades. Several examples of successful aerial fire suppression operations in both Victoria and South Australia are highlighted in the risk assessment.
