TenneT

TenneT was responsible for delivering the grid connection concept for the Doordewind offshore wind farm zone, including the connection serving Doordewind II (the second 2 GW site). TenneT’s scope described the provision of dedicated offshore and onshore grid connection infrastructure to bring electricity from the Doordewind area to the Dutch high-voltage grid at Eemshaven. The project was framed as two separate 2 GW underground cable systems, each supported by an offshore platform and an onshore converter station, enabling connection of the planned 4 GW Doordewind zone in two steps. TenneT’s publicly described plan included routing from the Doordewind zone in the northern Dutch North Sea via Schiermonnikoog, through the Wadden Sea, and then onshore to Eemshaven, with the cable connections fully installed underground along the selected corridor. The schedule presented envisaged completion of the works and readiness for operation in the early 2030s (with project works targeted to be finished by 2033). In addition to the grid infrastructure delivery, TenneT outlined an approach involving environmental and stakeholder considerations, including continued ecological and land-use investigations and structured public participation during the project decision and permitting process.
