Star of the South project cuts turbine number

Over a million households will benefit from this.

Star of the South, an offshore wind project in Australia, has reduced its proposed number of turbines for the plant to 150 from 200, showing advancements in the technology.

This was one of the key updates shared by Star of the South after five years of feasibility studies and consultation with stakeholders.

Star of the South secured a Commonwealth feasibility licence in May which confirmed its location at least 10 kilometres (km) off the coast – a further 3 km offshore than originally planned.

“We’ve 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,” said Star of the South CEO Charles Rattray.

“There’s also new technology, new government requirements, and a fast-evolving energy landscape to adapt to as we plan for Star of the South,” he added.

Aside from the turbine count, Star of the South said turbines will be positioned to avoid high profile reefs, whilst the gap between the ocean and turbine blades has increased from 25 metres (m) to 35 m to provide a safe zone for seabirds to fly and forage.

Advanced technologies to reduce underwater construction noises are being studied, whilst a “no trench” construction method will be used where cables come to shore, to protect the beach and dunes above.

Star of the South said work is ongoing  to adapt the underground transmission route, in line with VicGrid requirements.

Once in its full capacity, Star of the South is projected to power 1.2 million homes, inject around $3b into the Gippsland economy, and create up to 200  jobs across 30 years of operations.
