Delivery outlook not forecast

We don't put a delivery estimate on this project yet. No authority has granted rights to this site, so there is nothing to date a schedule from. That changes the moment the seabed is awarded, a consent application is filed, or the project is named in an auction.

Revenue & offtake route to market — open

No offtake secured — route to market open

Korea RPS/REC auction — pre-auction; no award confirmed

The routes describe what exists in this market — not a prediction of which the project will take.

MCEE's ten-year roadmap (2026-06-30) schedules 1.7-3.0 GW for 2026 H2 — fixed 1.3-2.0 GW, floating 0.4-1.0 GW. No 공고 date published as of 2026-08-26; the ministry began collecting military-operability consultation requests for H2 bidders from April 2026.
