TenneT acted as the transmission system operator responsible for providing the offshore grid connection for the IJmuiden Ver Wind Farm Site Gamma-A in the Dutch North Sea. The connection concept described for Gamma-A was a 2 GW direct-current (DC) offshore grid link, designed to connect two separate 1 GW wind farm sites (Gamma-A and Gamma-B) to a single offshore energy platform, optimising use of shared offshore transmission infrastructure. The published project information stated that the wind farm would connect to a TenneT substation platform offshore, where power collected from the wind farm’s 66 kV park cabling would be converted and transformed to the transport voltage for the link to shore. The offshore export connection was described as a 525 kV DC cable system to an onshore station, where the DC power would be converted to 380 kV alternating current (AC) for integration into the Dutch onshore high-voltage transmission network. This role covered the grid connection interface enabling the future permitted wind farm to deliver electricity from the IJmuiden Ver Gamma-A site to the national grid, including the shared offshore platform arrangement and the offshore-to-onshore transmission concept referenced in the permit preparation materials for the tender.
