A Modification Application has been submitted for the Liverpool Range Wind Farm. We are proposing to increase the renewable energy that the Project can generate by using taller turbines while reducing the number required.

Recent Consultation

We undertook community consultation drop-in sessions in both Coolah and Cassilis between 24 - 26 October, to discuss our plans to construct and operate a temporary workforce accommodation (TWA) facility and temporary Project-specific quarry during the construction phase of the Project.

We would like to thank both the Cassilis and Coolah communities for attending the sessions and providing feedback. We are in the process of completing a full review of all feedback collected, however based on community consultation in Cassilis, the Project will not be proceeding with the Cassilis location to host the TWA facility and will be pursuing with the proposed Coolah location.

Following a review of submissions received during public exhibition and further technical investigations, we are aware that there is a substantial shortage of short- and long-term rental accommodation in the local area that could be used by the construction workforce. The peak construction workforce for the Project is expected to reach around 550 workers and construction is expected to occur over a 4-year period. To reduce pressure on existing rental accommodation we are proposing to construct and operate a TWA facility close to the Project site.

We investigated over twenty potential locations for a TWA in and around Coolah and Cassilis townships, however many of the sites had significant environmental or social constraints and did not warrant further consideration. Through this investigation process, we short-listed two potential TWA sites, one located within the Project site approximately 3 km east of Coolah township off Vinegaroy Road, and another near on the southern side of Cassilis township off Cassilis Road (refer to fact sheet below).

In light of community feedback and consultation outcomes, Tilt Renewables is proposing to proceed with the site located approximately 3 km east of Coolah township. Amongst other reasons, this site was selected due to its negligible environmental constraints and central locality within the Project site boundary to minimise commute times for construction staff travelling to and from work fronts. The siting of the TWA Facility has sought to ensure suitable buffer distances from local townships to minimise social, noise and traffic impacts to residents as far as practicable.

Tilt Renewables has undertaken a suite of technical impact assessments to identify potential impacts associated with the TWA. Some of the potential impacts related to TWAs include:

  • Possible disturbances to the nearby community in terms of noise or increased traffic
  • Potential impacts on the environment of the chosen site and its surroundings
  • Social impacts associated with community wellbeing, access to essential services, health and safety, and security

More detailed information on the findings of these impact assessments, including possible mitigation measures, is available at the Coolah Shopfront (50 Binnia Street) and the Cassilis Post Office.

As part of the RTS Project, we are proposing a temporary Project-specific quarry located within the Project site approximately 10 km northwest of Cassilis township, off Rotherwood Road (refer to fact sheet below).

Detailed site geological investigations confirm that the proposed site is able to produce a range of suitable quarry product required for construction of the internal road network, hardstand areas, turbine foundations and other associated civil works required to construct the wind farm project and associated public road upgrades/repairs.

Sourcing suitable materials from within the Project site would avoid the need for large numbers of heavy vehicles to transport quarry products from significantly greater distances from existing quarries elsewhere in the broader region. Reducing the number and length of heavy vehicle trips on the broader road network is expected to result in less congestion and delays, improved safety outcomes, and reduced construction costs.

Detailed information about the proposed quarry site and the findings of detailed environmental impact assessments, including possible mitigation measures, is available at the Coolah Shopfront (50 Binnia Street) and the Cassilis Post Office.

Response to Submissions

In response to agency and community submissions received during the public exhibition of the Modification Application, we have made a number of key changes to the design and layout for the Response to Submissions (RTS) Project.

The key changes proposed by the RTS Project (compared to what was proposed in the Modification Application) are:

  • A further reduction in the number of proposed wind turbines from 220 to 185.
  • A reduction in the maximum blade tip height from 250 m to 215 m above ground level (AGL).
  • We have now selected the Vestas V172 7.2 MW turbine, which has a blade length of 85 m. This equates to a rotor diameter of 172 m. We had previously assumed a rotor diameter of approximately 210 m.
  • Removal of five turbines that were proposed by the Mod-1 Project in the north-east of the site near Coolah Tops National Park, to minimise visibility from Pinnacle Lookout and reduce potential noise impacts within the National Park.
  • Amendment to the External Transmission Line alignment to completely avoid a portion of Durridgere State Conservation Area, near Turill.
  • Shifted three turbines (D40, D43 and E31) to avoid impacts to a communications link proposed by the NSW Telecommunications Authority (NSW Telco).
  • Reduced area of Development Corridor from 12,601.6 ha to 8,718.2 ha due to design changes, including removal of turbines and associated access tracks, and implementing steeper cut and fill batters where feasible.
  • Removal of Coolah Road from the Project such that no light, heavy or over-size/over-mass (OSOM) vehicles would be permitted to use Coolah Road during construction.
  • Reduction in total number of site access points from 90 to 74.
  • Removed optional locations for various infrastructure, such as duplicate access track site entrances and associated access track alignments, and substation locations.

The proposed modifications also reflect the outcomes of substantial design optimisation work and constructability assessments carried out to prepare the Project for construction.

Biodiversity offsets

We have made significant progress on securing a range of land-based biodiversity offsets and are on-track to meet the RTS Project’s biodiversity offset credit obligation prior to commencement of construction. One of the offset sites is located in one of two Mapped Important Habitat Areas for Regent Honeyeater (RHE) in NSW and once established, will create a new 18 km long continuous habitat corridor for a range of species, including the RHE, that will be secured into perpetuity.

We are working closely with DPE and landholders to prepare all of the application documentation required to register these new sites to offset the unavoidable impacts associated with the Project. Notwithstanding this, we will continue to look for opportunities to reduce the Project’s disturbance footprint as we progress through the detailed design process and into construction.
