Premium Reports
DeepWind’s premium reports provide structural, execution-focused analysis beyond headline policy commentary.
Paid research on Japan's offshore wind market. Not policy commentary: each report tests whether projects clear, working from cost structure, supply constraints and financing conditions. Every assumption is stated in the text, so you can swap in your own and see what moves.
Latest / Floating wind bankability
Floating Wind: The Bankability Test
Why floating wind is not yet bankable in Japan, and what has to align before it scales.
The constraint is not the platform. Installation vessels, marshalling ports, mooring and anchor supply, and dynamic cables have to unlock in step, and a project stalls if any one of them lags. The report quantifies that bottleneck node by node, ranks the variables that actually move bankability, and sets out a ladder of the conditions under which floating scales.
Minimum DSCR (how comfortably a project covers debt service in its tightest year), equity IRR thresholds, the CAPEX breakdown and zone-level capacity factors are all stated explicitly.

Re-tender viability assessment
Can Japan's Offshore Wind Re-tenders Actually Work?
What conditions the three re-tendered zones need before they are bankable.
Site-condition scoring, LCOE and project IRR modelling, sensitivity across six parameters, and an execution-risk overlay for Noshiro-Mitane-Oga (495 MW), Yurihonjo (840 MW) and Choshi (390 MW). Choshi carries the strongest baseline economics at LCOE 27.5 JPY/kWh and IRR 5.0%, where 13 m water depth offsets weaker seabed conditions.
The finding: re-tenders can proceed, but they do not close the viability gap. WACC and power price dominate, and the report marks the levels at which each project stops working.

Round-specific policy analysis
Japan Offshore Wind Round 4: What Actually Changed and What Didn't
Sorting the rule changes that reach execution from the ones that stop at paper.
Round 4 read as the point where the market leaves the ambition-driven phase for the viability-driven one. The report separates what the government changed, what developers expected to change and did not, and where the execution gap stayed open, then sets out who gains and who is still exposed through 2026 to 2028.

Flagship structural report
Why Japan's Offshore Wind Pipeline Is Broken and How It Can Be Repaired
Withdrawals and delays treated as symptoms of one system, not as separate events.
The question is not whether an individual project can be optimised, but whether tender design, cost assumptions, supply-chain build-out and financing structure can be made to fit together. Built on direct input from EPCs, suppliers, consultants and researchers working in the market, the report shows where viability breaks down at each stage of the pipeline.
The longest of the four, and the analytical base the later reports build on.
