RWE's Nordseecluster A has started supplying electricity to Germany's transmission network, with the initial power feed occurring on either 21 or 22 July 2026. The first turbine was installed roughly six weeks prior, in late May or early June 2026, and commissioning of the remaining units is ongoing.

The 660-megawatt Phase A consists of 44 Vestas V236-15.0 MW turbines. Commercial operation is slated to begin in early 2027. Phase B, with a capacity of 900 MW, will add 60 turbines of the same model, bringing the total turbine count to at least 104. Foundation work for Phase B is scheduled for 2027, followed by turbine erection in 2028, and the start of operations in early 2029.

Once both phases are operational, the Nordseecluster will have a combined capacity of 1,560 MW. RWE estimates annual generation of about 6.5 TWh, which the company says is equivalent to the electricity consumption of roughly 1.6 million households. The project is located approximately 50 kilometers north of the island of Juist in the German exclusive economic zone of the North Sea, spanning four sites designated NC 1 through NC 4.

Power from the cluster is transmitted via two offshore substations to a converter platform operated by the grid operator. RWE holds a 51% stake in the venture, with Norges Bank Investment Management owning the remaining 49%. RWE is responsible for both construction and operation.

Amazon has entered into a power purchase agreement for 110 MW from Nordseecluster B, securing a portion of the future output. Manufacturing of components for the second phase is already underway.
