The Australian Energy Market Operator (AEMO) forecasts that about 90 per cent of the country's coal-fired power generators will close by 2035. Offshore wind offers large, stable generation capacity that can replace retiring baseload assets while supporting grid reliability. Coastal load centers, particularly in southeastern Australia, are located near high-quality offshore wind resources, reducing transmission congestion risks relative to remote onshore generation. Developing Victoria's offshore wind power industry off the Gippsland coast could cut the number of powerlines needed by about 930 km, delivering a $5 per megawatt-hour reduction in wholesale electricity prices across the entire National Electricity Market between 2033 and 2040. The need to maintain energy security during the transition away from fossil fuels is accelerating procurement of long-duration, utility-scale renewable capacity.
Technological Advancements and Cost Reductions
Advances in turbine size, floating foundation technology, digital monitoring systems, and installation techniques are improving project efficiency and lowering lifecycle costs. Larger turbines increase energy output per unit, reducing the number of installations required and optimizing seabed utilization. The above 5MW segment dominated the market with a 78.5% share in 2025, underscoring the industry preference for high-capacity turbines that maximize energy output and reduce levelized cost of electricity. Improvements in subsea cabling, grid connection design, and predictive maintenance systems enhance operational reliability and reduce downtime. Developers are prioritizing high-resolution wind and ocean data collection to optimize turbine configuration, foundation engineering, and grid connection design. AI-powered wind resource assessment tools, predictive maintenance analytics, and digital twin technologies are enabling real-time performance optimization and condition-based maintenance scheduling.
