Cable installation offshore wind farms Hollandse Kust Noord and West Alpha, the Netherlands

Commissioned by TenneT, the consortium Jan De Nul Group and LS Cable & System will supply and install the high-voltage cables that will connect the Dutch offshore wind farms Hollandse Kust Noord and Hollandse Kust West Alpha with the onshore electricity grid.

Jan De Nul Group will transport, install and protect the cables. LS Cable & System will be responsible for the design and production of the cables. The offshore installation works will take place in 2022-23.

These wind farms produce enough green energy to supply one million households per year.
Both Hollandse Kust Noord and Hollandse Kust West Alpha will each be connected by two 220 kV high-voltage cables. A total of four cables with a total length of 210 km will therefore connect to the Dutch electricity grid at Beverwijk, just north of the port of IJmuiden. Once operational, these wind farms will produce up to 1,400 MW, enough to supply one million households with green electricity for an entire year.
