Bird-Safe Wind Turbines:Comprehensive Guide
Exploring Bird-Safe Wind Turbines:
A Comprehensive Guide
If you've considered integrating a small wind electric system into your property, you've likely already conducted initial evaluations regarding wind availability, zoning regulations, and economic feasibility. Now, let's delve deeper into the factors associated with installing a wind system, particularly focusing on the importance of bird-safe technology.
Installation and Maintenance
For the successful implementation of a wind electric system, professional installation is paramount. An accredited installer can ensure proper setup and adherence to safety standards, offering additional services such as permitting. It's essential to verify the installer's credentials, including license and references, to guarantee quality service. With routine maintenance, a small wind electric system can provide reliable energy for up to two decades or more.
Siting a Small Electric Wind System
Choosing the optimal location for your wind system is crucial for maximizing its efficiency while minimizing environmental impact, particularly on bird populations. Your professional installer will assess various factors, including wind resources and system specifications, to determine the ideal placement. It's imperative to consider existing obstacles and future developments, ensuring the turbine is positioned upwind of buildings and trees to prevent potential harm to birds.
Sizing Small Wind Turbines
Selecting the appropriate turbine size is essential for meeting your energy needs while minimizing environmental impact. A professional installer will assist in establishing an energy budget and determining the optimal turbine size based on wind conditions and usage patterns. Energy efficiency measures should also be considered to reduce electricity demand, thereby potentially reducing the required turbine size.
Estimating Annual Energy Output
An accurate estimate of the annual energy output is crucial for assessing the system's viability and ensuring it meets your electricity requirements. Working with a professional installer, you'll consider factors such as wind turbine specifications, site-specific wind speeds, and tower height to calculate projected energy production. Adjustments for elevation and wind frequency distribution will further refine these estimates.
Grid-Connected and Off-Grid Systems
Grid-connected wind energy systems offer the advantage of offsetting utility-supplied electricity consumption and potentially earning credits for excess energy production. Modern grid-connected turbines operate in tandem with the utility grid, providing backup power during outages. Off-grid or hybrid systems, on the other hand, offer energy independence and reliability for remote locations, utilizing wind power in combination with other renewable sources.
Conclusion
Integrating a bird-safe wind electric system into your property offers a sustainable energy solution while minimizing adverse effects on bird populations. By prioritizing proper installation, maintenance, and thoughtful siting, you can harness the power of wind while safeguarding biodiversity.

Optimizing Wind Turbine Position and Height for Bird-Safe Installation
Choosing the right location and height for your wind turbine is critical for maximizing energy production while minimizing maintenance needs. Here's what you need to know about positioning and tower height considerations for bird-safe wind turbine installations.
Assessing Your Site
Determining if wind power is viable for your property requires more than just online wind speed data. Factors like terrain, obstacles, and wind shear need to be considered. Wind shear, which causes slower wind speeds closer to the ground, can significantly impact turbine performance, especially at heights below 30 meters. Conducting local measurements using an anemometer provides more accurate data for site assessment.
Local Measurements with an Anemometer
Anemometers measure average wind speeds and directions over a specified duration. Leaving the device in place for at least three months ensures representative data. While anemometers can be costly, some retailers offer readings as part of their service. Guidelines outlined in the International Standard IEC61400-12 ensure accurate readings for informed decision-making.
Siting Considerations
Wind power is typically more viable in open rural areas with fewer obstacles. Urban locations may still benefit from wind power, especially in coastal regions or atop high-rise buildings with strong winds. Turbulence caused by obstacles like trees and structures can increase maintenance needs and costs over time. Special blade designs can mitigate noise issues associated with higher wind speeds.
Ideal Siting
The ideal location for a wind turbine is on a hill higher than surrounding terrain, with minimal obstacles. Selecting the highest point on your property reduces turbulence and maximizes wind exposure. Tower design, such as guyed or monopole, affects the footprint and cost of the installation. Choosing the right mounting option opens up potential sites while minimizing environmental impact.
Tower Height
Tower height significantly impacts wind flow quality and energy production. Taller towers provide cleaner airflow and higher energy returns, justifying the initial investment. However, zoning regulations and planning restrictions may limit tower height options. Understanding local regulations beforehand ensures compliance and avoids potential setbacks.
Conclusion
By carefully selecting the position and height of your wind turbine, you can optimize energy production while minimizing environmental impact and maintenance needs.

Regulations under the Environment Protection Act
In July 2021, the Environment Protection Act 2017 and Environment Protection Regulations 2021 established a new regulatory framework for wind turbine noise.
From 18 October 2022 amendments to the Environment Protection Regulations (Division 5 of Part 5.3) introduced new, ongoing wind turbine noise regulations.
These regulations provide clarity for wind energy facility operators and investors, and assurance for communities regarding the protection of human health and the environment from wind turbine noise.
Requirements for wind energy facility operators under these regulations include:
-
compliance with noise limits in accordance with the relevant noise standard
-
an upper noise limit of 45 dB(A) or background sound plus 5 dB for properties subject to stakeholder agreements
-
completing a post construction noise assessment within 12 months of commencement of operations
-
implementing a noise management plan, including a complaints management plan
-
providing an annual statement detailing the actions taken to ensure compliance
-
conducting noise monitoring every five years, from 1 January 2024.
As Victoria’s independent environmental regulator, the Environment Protection Authority (EPA) is the primary regulator for wind energy facility noise, for both new and existing facilities.
EPA's updated Wind Energy Facility Turbine Noise Regulation Guidelines help industry to comply with their regulatory obligations, including where amendments to the regulations have been made.
To find out more about how the regulations were developed visit Engage Victoria.
Changes to Victoria’s planning system
From 3 August 2021 changes were made to planning schemes to align with wind turbine noise requirements in the Environment Protection Regulations.
This removed a requirement to place mandatory conditions for operational wind turbine noise on new planning permits as operational wind turbine noise is now addressed by the Environment Protection Regulations.
Conditions of existing planning permits continue to apply. The Minister for Planning continues to be responsible for assessing applications and approving new permits.
Wind energy facility permit holders may apply to amend existing permits to remove these conditions. Applications to amend permits will be referred to the EPA for comment.
From 4 July 2023, further changes were made to planning schemes to better align the pre-construction requirements with the regulatory framework for operational wind turbine noise under the Environment Protection Act 2017 (more specifically, Division 5 of Part 5.3 of the Environment Protection Regulations 2021).
The amendment ensures that pre-construction (predictive) noise assessment reports required for permit applications are subject to the same requirements as post-construction reports under the operational noise framework, and more clearly assess whether the facility can comply with the relevant operational noise limit imposed by that framework.
Complaints about wind energy facility noise
Concerns about wind turbine noise should be raised directly with the wind energy facility operator. The operator will respond according to their complaints management procedures.
If unresolved, concerns about noise pollution can be reported to the EPA.
For further assistance contact the Australian Energy Infrastructure Commissioner.
