First Hollandse Kust (west Beta) export cable in place and substation jacket on the way

This weekend, the first of two export cables for TenneT’s Hollandse Kust (west Beta) offshore grid connection was successfully pulled underneath the dunes at Velsen. At the same time, the jacket for the connection’s offshore substation was underway.

The export cables were manufactered by Orient Cable in China and arrived in the Netherlands in April. In the coming days, contractor NBOS (Boskalis Offshore Energy & Orient Cable ) will be burying this 220 kV AC cable into the seabed. Cable number two will follow soon.

Jacket for offshore substation on route

A few days ago, the jacket for the Hollandse Kust (west Beta) substation left the Smulders yard in Vlissingen. On a pontoon, the jacket being transported to the offshore wind farm, approximately 53 kilometers off the coast of Egmond aan Zee. Here it will be installed by Heerema’s heavy lift vessel Sleipnir. UPDATE: The jacket was installed a day later.

Through the 700 MW grid connection, the power produced by RWE / OranjeWind’s Hollandse Kust (west Beta) offshore wind farm will be transported to the mainland. This will make approximately 3.3 terawatt-hours of sustainable electricity available, which is roughly equivalent to the annual consumption of 1 million Dutch households. The Hollandse Kust (west Beta) offshore wind farm is expected to enter service in 2025.
