Joint study: Japan Fixed-Bottom Offshore Wind

Receive our free analysis on cost drivers and the 2040 outlook for fixed-bottom offshore wind in Japan.

The Renewable Energy Institute in Japan and Aegir Insights jointly released the report "Japan Fixed-Bottom Offshore Wind Cost Drivers and the 2040 Outlook" in April 2026.

The report was produced as an independent research initiative and examines how Japan can accelerate the deployment of fixed-bottom offshore wind by identifying current cost gaps with Europe and exploring pathways for cost reduction through 2040. Using a detailed techno-economic model, it benchmarks Japan's capital expenditure against a European reference case.

The analysis highlights how Japan's distinct policy environment and challenging natural conditions - such as strong seasonal weather patterns, complex seabed geology, and the need to design for earthquakes and typhoons - as well as the relative immaturity of Japan's offshore wind market, contribute to higher costs compared to Europe. By clarifying these differences, the report provides insights into where efficiencies and cost reductions may be achieved by 2040.

The study is available complimentary.
