Sweden-headquartered wind developer Vattenfall AB signed an agreement with grid operator TenneT Holding BV to connect the 700-MW Hollandse Kust Zuid 1&2 wind projects off the coast of the Netherlands to the Dutch grid.
Under the agreement, the Vattenfall-owned wind project will be connected to TenneT's Hollandse Kust Zuid Alpha offshore platform.
The Hollandse Kust Zuid offshore grid will comprise two 700-MW transformer platforms at sea, two 220 kV-ac cables per platform, a planned onshore substation and an expansion of the existing Maasvlakte HV onshore substation.
One connection will become operational in 2021, and the second will come online in 2022. TenneT has been designated the operator of the offshore transmission grid needed to connect wind energy facilities to the Netherlands' transmission system.
"The offshore grid is now really taking shape, first with 1,400 MW in the Borssele wind area, followed by Hollandse Kust Zuid and finally Hollandse Kust Noord in 2023," TenneT Senior Manager Offshore Nederland Marco Kuijpers said in a Jan. 15 news release. "In the meantime, we're preparing for the next North Sea projects in consultation with the Ministry of Economic Affairs & Climate."
