Australia's Star of the South offshore wind farm has concluded five years of feasibility studies and consultations, refining its project design in preparation for development. The project secured a Commonwealth Feasibility Licence in May, confirming its location at least 10km off the coast, extending 3km further than originally planned.
Key project design updates include reducing the number of turbines from 200 to 150, reflecting advancements in hardware technology. The turbines will be strategically positioned to avoid high-profile reefs and protect marine habitats. Additionally, the gap between the ocean surface and turbine blades has increased from 25 meters to 35 meters, based on bird flight height data, to provide a safer zone for seabirds to fly and forage.
The project will explore both “established and cutting-edge technologies” to reduce underwater construction noise, ensuring the right measures are in place to protect whales. A “no trench” construction method will also be used where cables come ashore, safeguarding the beach and dunes above.
Work is currently underway to adapt the project's underground transmission route, in line with VicGrid requirements.
Star of the South CEO Charles Rattray said, “We have learned a lot since we first set out to explore the potential for offshore wind in Gippsland five years ago. We have collected vast amounts of scientific data and listened to local advice to help develop a project that can contribute to Victoria's energy security, the environment and local communities. There is also new technology, new government requirements, and a fast-evolving energy landscape to adapt to as we plan for Star of the South.”
