RWE Installs 22nd Turbine at Nordseecluster A, Passing the Halfway Mark

RWE has passed the halfway mark at its Nordseecluster A offshore wind farm in the North Sea. As of 31 August, 22 of the 44 planned Vestas turbines are in place at the site, around 50 kilometres north of the German island of Juist.

DEME's Norse Wind, a wind turbine installation vessel capable of carrying up to five turbine sets per cycle, has been running the installation work. The first turbine went up in June; by late July, Nordseecluster A had started feeding electricity into the German grid.

The remaining 22 turbines are due in place by the end of 2026. Testing and commissioning will proceed turbine by turbine. The full 660 MW first phase is expected to be grid-connected at the start of 2027.

Nordseecluster is RWE's largest offshore wind project under construction. RWE holds a 51% stake and manages construction and operation; Norges Bank Investment Management owns the other 49%.

The project covers two phases. Nordseecluster A at 660 MW is the first; Nordseecluster B will add 900 MW, for a combined capacity of 1.6 GW. Foundation production for Nordseecluster B is already under way, with installation of those foundations set to start in 2027. The 60 Vestas turbines for the second phase are planned for 2028, with commercial operations expected in early 2029. At full output, both phases together are expected to produce around 6.5 TWh of electricity per year.

MarineRadar data shows the vessel JUIST recording 102 unique device lookups in the past 48 hours, a level of interest that points to active maritime monitoring of the area north of the island during the construction period.
