System Testing

DELAYED +2mo (May 2026): 50Hertz lists an expected OST-6-1 completion date of 01/07/2028 (not final; appeals pending). System testing/commissioning typically continues into/after energisation and pre-COD; the current July-2028 system_testing date is too tight relative to the grid-link completion/energisation window, so shifting testing to Q3 2028 to reflect a more realistic commissioning sequence (while still consistent with mid-2028 overall commissioning target). --- Skyborn Renewables and transmission system operator 50Hertz have agreed a framework for construction and operation of the OSS Darß and OSS Zingst offshore platforms and the OST‑6‑1 grid link, with the grid connection system for the 976.5 MW Gennaker offshore wind farm planned to be commissioned—following testing and commissioning activities—by July 2028.
