Ramboll was appointed by Energinet to support development of the North Sea Energy Island by delivering conceptual engineering for the project’s electrical infrastructure. The assignment focused on defining workable, future-proof solutions for collecting and transmitting very large volumes of offshore wind power from the hub and exporting it over long distances to multiple offtakers and neighbouring markets while minimising losses. The scope described in the source relates to early-phase engineering and concept development for an eventual build-out that was planned to start at multi‑gigawatt scale (with later expansion). Ramboll’s work was positioned as part of Energinet’s broader preparatory programme for Denmark’s energy islands, supporting the tender phase and helping translate the energy-island concept into implementable technical options. The source states the project value at DKK 225 million (approximately EUR 30 million) and notes an option for subsequent maintenance, indicating the engagement was structured as a major consultancy package with potential follow-on services as the project progressed. This role is recorded as an engineering consultancy engagement during the project development stage, commissioned by the Danish TSO responsible for the transmission system connection from the future hub to shore and to interconnectors.
