Contractor mixture NRG (Denys, Alsema and Van Vulpen) will realise the hyperlink between the offshore cables for the wind farm Hollandse Kust (west Beta) and the transformer station in Wijk aan Zee for TenneT. NRG will set up 2.5 km of excessive voltage underground cables from Velsen seaside. This might be achieved via underground directional drilling, as used for the Hollandse Kust (north) and (west Alpha) tasks.
The award of this contract marks the continuation of the profitable collaboration between TenneT and the consortium of contractors for the connection of offshore wind farms within the IJmond area. NRG is presently finishing up the ultimate drillings from Velsen to finish the cable connection for the three offshore wind farms between the transformer station at Wijk aan Zee and the high-voltage substation alongside the A9 freeway in Beverwijk.
Attraction process by the Council of State
The work is anticipated to start out someday within the autumn of 2023. Nonetheless, this will depend on an ongoing attraction process on the Council of State. The listening to will happen on July 7, after which a call is anticipated subsequent fall. So as to not lose any priceless time in connecting offshore wind vitality, TenneT has acquired permission from the Ministry of Financial Affairs and Local weather Change to award this venture element upfront.
Constructing on
This implies NRG can begin detailed engineering and drawing up work plans. The contractor can fortunately draw on the data and expertise of the previous yr. “We all know the world and the folks nicely, we’ve got the know-how and the precise gear, and we’ve got expertise of strategies which have proved their value over the previous yr,’ says venture manager Mark de Bruijn on behalf of NRG. “By working for this venture we will construct on our good relationships with the events concerned within the space.”
Specialist work with a watch for the area people
TenneT can be happy with the continued cooperation. Dick Vergoes Houwens, venture manager for onshore cable on behalf of the grid operator, mentioned: ‘NRG’s workforce did a wonderful job with the sooner sequence of drillings beneath the dunes. That is distinctive, specialist work that calls for excessive care. Regardless of varied modifications within the schedule, NRG did a wonderful job due to their flexibility and dedication, and every thing was accomplished on time with due regard for the area people.”
About Hollandse Kust (west Beta)
The offshore wind farm Hollandse Kust (west Beta) may have a capability of 700 MegaWatt and might be put into operation in 2026. The Hollandse Kust (west Beta) offshore grid is the whole grid connection from the Hollandse Kust (west Beta) offshore wind farm to the brand new transformer station at Wijk aan Zee. From there the facility goes by way of underground cables to the high-voltage station alongside the A9 freeway in Beverwijk. This high-voltage station is a part of the nationwide high-voltage grid (Noordring 380 kV).
The full venture consists of:
- The offshore transformer platform: all wind generators might be related to this platform and the voltage stage might be elevated from 66 kiloVolt (kV) to 220 kV;
- The offshore 66 kV interlink cable between the platform for west Alpha and the platform for west Beta;
- Two 220 kV offshore cable programs to the transformer station. The cables will come ashore south of Wijk aan Zee;
- Enlargement of the transformer substation being constructed for the Hollandse Kust (north) and (west Alpha) wind farms. On the transformer station, the facility might be introduced from 220 kV AC to 380 kV AC. From there, the facility might be fed into the nationwide high-voltage grid by way of underground 380 kV cables some ten kilometers additional alongside the A9 freeway.
