Japan’s August 2026 lightning rule requires operators to know whether a strike occurred. On 28 September METI asked all operators to stop turbines for monthly blade checks.
Japan names offshore wind O&M a priority use for marine drones. How O&M automation moves OPEX and bankability — and why record capital is heading abroad first.
Why This AiP Matters On 25 May 2026, Obayashi Corporation received Approval in Principle (…
Analysis of the May 2025 Arayahama turbine accident: how a compliant CFRP blade failed from the inside, the missed retrofit, and METI’s new inspection rules.
JB Energy launched Aura Sul Wind Phase 2 on June 2, 2026. FEED, licensing and metocean work now begin for Brazil’s first floating wind pilot.
Japan’s offshore wind tech landscape in 2026: floating platform types, NEDO Phase 2 demos, EEZ expansion. From semi-sub dominance to 15 GW by 2040.
Japan targets 30 to 45 GW of offshore wind by 2040, yet one 16.8 MW project runs under the national law. Costs, grid, ports and policy decide the gap.
A wind turbine turns wind into rotation, then electricity. Output rises with the cube of wind speed until rated power. See how it works on a 15 MW machine.
Innovations in floating offshore wind technology are underway! NEDO’s project aims for cost reduction and international expansion, with R&D planned from 2025 to 2029. This initiative will transform Japan’s renewable energy landscape!
The Phase 2 of the floating offshore wind demonstration project is underway! Discover new technologies and future possibilities. Read more! ▶
