Chantiers de l'Atlantique builds and integrates offshore electrical substations for Nordseecluster

The supply agreement between RWE AG's Nordseecluster development and Chantiers de l'Atlantique secures two 800 MW offshore electrical substations, critical infrastructure for the 1.6 GW German offshore wind project. This arrangement allows RWE, a leading German energy company focused on renewables, to de-risk the transmission backbone during the Nordseecluster's construction phase. Chantiers de l'Atlantique, a Saint-Nazaire-based marine engineering specialist, leverages its established expertise in offshore energy platforms for this significant contract. The deal ensures the timely integration of essential power transmission assets, vital for the Nordseecluster's eventual operation. While the financial value remains undisclosed, this agreement represents a key procurement step for RWE's substantial offshore wind development. For RWE AG, headquartered in Essen, Germany, this supply agreement for the Nordseecluster reinforces its strategic focus on large-scale renewable energy, particularly offshore wind. As a leading German energy company, RWE consistently expands its portfolio in offshore wind, onshore wind, solar, and battery storage. Chantiers de l'Atlantique, with its origins in Saint-Nazaire in 1861, further solidifies its position as a critical supplier for the offshore energy sector, building on its extensive experience in naval vessels and cruise ships. The French company's specialization in offshore energy platforms makes it a natural fit for delivering these complex electrical substations. This announced construction-stage deal, revealed on 2026-03-07, demonstrates the ongoing demand for specialized marine engineering capabilities across Europe's expanding offshore wind market.
