In 2025, 50Hertz commenced offshore cable route work and onshore landing activities for the OST-6-1 grid connection near Dierhagen on the Baltic Sea coast. A 50Hertz press release dated 27 January 2026, announcing the cooperation agreement between 50Hertz and Skyborn Renewables for the Gennaker offshore converter platforms, states that a 2025 planning approval decision for the territorial waters section "enabl[ed] offshore cable route work and onshore landing activities near Dierhagen to begin last year." Since the press release is dated January 2026, "last year" refers to 2025, confirming that initial cable installation activities — including export cable route preparation and landfall works — commenced during 2025. The cable installation programme covers three 220 kV AC submarine export cable systems linking the offshore substations OSS Darß and OSS Zingst to the onshore substation at Gnewitz, with Hellenic Cables responsible for Lot 1 (western systems, ~105 km submarine + onshore) and ZTT for Lot 2 (eastern system, ~88 km total route). Asso.subsea is performing offshore cable laying for Lot 1 using its cable-laying vessel Atalanti.
