Australia Wind Energy Market Size and Share - Growth Analysis Report and Forecast Trends 2026-2030

Australia's wind energy sector encompasses both onshore and offshore wind farm development, operations, and maintenance activities across the country. The market includes utility-scale projects, distributed wind installations, and associated infrastructure such as transmission connections and grid integration systems. As a key pillar of Australia's renewable energy transition, wind generation currently accounts for a significant and growing share of the national electricity supply.

• •Market valued at approximately $4.6 billion in 2025 with a compound annual growth rate of 11.6%
• •Segmented between onshore wind, which dominates current capacity, and offshore wind, which is emerging with several planned projects
• •Operates within a National Electricity Market framework overseen by the Australian Energy Regulator and Australian Energy Market Operator

Government policy and regulatory frameworks are central to market expansion, with state renewable energy targets and federal initiatives creating a supportive investment environment. The declining levelized cost of energy from wind projects, combined with growing corporate power purchase agreements, is accelerating new project development. Aging coal-fired generation capacity is also being retired, creating room for wind and other renewables to fill the supply gap.

• •Federal and state government renewable energy targets and policy incentives driving project investment
• •Corporate demand for renewable energy through power purchase agreements supporting offtake certainty
• •Coal-fired power station retirements creating demand for replacement renewable generation capacity

The market is primarily divided between onshore wind, which represents the majority of installed capacity, and the emerging offshore wind sector. Onshore projects are concentrated in regions with strong wind resources, particularly in southern and eastern Australia. Offshore wind is in early development stages with several proposed projects targeting southern and western coastal zones.

• •Onshore wind leads current capacity, with established project clusters in South Australia, Victoria, and New South Wales
• •Offshore wind represents a nascent but high-potential segment, with multiple feasibility and planning-stage projects in southern waters
• •Regional distribution varies by state renewable targets and grid connectivity, with South Australia and Tasmania having the highest wind share in their generation mixes

What are the recent trends and outlook?

The market is expected to maintain strong growth momentum through the coming decade as Australia pursues its renewable energy targets. Hybrid projects combining wind with solar and battery storage are becoming more common, improving grid stability and project economics. Continued investment in transmission infrastructure and grid modernization will be critical to unlocking new wind development zones and integrating higher shares of variable renewable generation.

• •Growing trend toward wind-solar-battery hybrid projects to optimize land use and provide dispatchable renewable energy
• •Offshore wind development accelerating as feasibility studies progress and regulatory frameworks mature
• •Transmission infrastructure investment and grid upgrades identified as key enablers for continued wind capacity growth
