TenneT

TenneT was identified as the transmission system operator responsible for delivering the offshore grid connection for the IJmuiden Ver Wind Farm Zone Gamma-B site (approximately 1 GW). The RVO permit documentation stated that the wind farm would be connected to a TenneT offshore substation/platform as part of the Dutch offshore grid roll-out, enabling export of electricity from the offshore wind farm to the onshore high-voltage transmission system. The connection concept described for IJmuiden Ver Gamma-B was a shared 2 GW direct current (DC) offshore grid connection, in which two separate 1 GW wind farm sites (IJmuiden Ver Gamma-A and IJmuiden Ver Gamma-B) would connect to a single TenneT offshore energy platform. This shared-platform approach was presented as a way to optimise utilisation of the offshore grid infrastructure and reduce the amount of work, time, and cost compared with connecting the two sites in stages. The sources also referenced the landfall at Maasvlakte and the use of a 2 GW HVDC export connection to an onshore substation/converter interface, indicating that TenneT’s grid connection scope covered the offshore platform interface for wind farm connection and the transmission link from offshore to the onshore grid connection point. The project was described as pre-tender for the wind farm developer, with TenneT’s grid connection being the enabling infrastructure for the site.
