Hollandse Kust (zuid) Alpha, TenneT’s excessive voltage connection for offshore wind farms Hollandse Kust (zuid) I and II is prepared to be used. TenneT accomplished the set up and energization of the offshore grid connection. Wind farm developer Vattenfall can now join the wind generators to the excessive voltage grid. On high of that, the Hollandse Kust (zuid) Beta topside was efficiently put in this week.
Grid Readiness
TenneT acquired the ‘Grid Readiness’ certification from DNV GL for Hollandse Kust (zuid) Alpha on Tuesday March twenty second. Because of this this offshore grid connection absolutely complies with the situations set out within the so-called Offshore Wind Vitality Improvement Framework. Marco Kuijpers, Director of Giant Tasks Offshore: “With the energization of the Hollandse Kust (zuid) Alpha connection, the offshore grid that TenneT is constructing within the North Sea is beginning to take form. Hollandse Kust (zuid) Alpha is the primary connection of an offshore wind farm to the Maasvlakte and has a capability of 700 MW. The energization of Hollandse Kust (zuid) Beta later this yr will add one other 700 MW from wind farms Hollandse Kust (zuid) III and IV.”
Made in Dubai
Over the previous years, contractor Petrofac has been engaged on the fabrication of two Excessive Voltage Alternating Present (HVAC) transformer stations – additionally known as topsides – Alpha and Beta on the Drydocks World fabrication yard in Dubai. The Alpha topside was put in on the jacket within the North Sea, about 20 kilometers off the coast of The Hague, on Sunday December twenty sixth 2021. Sister topside Beta left the fabrication yard in Dubai final February and sailed on a Boskalis transport vessel in little over one month to the Alexiahaven on the Maasvlakte, the place it arrived final week.
Offshore firm Allseas carried out the set up
Within the Alexiahaven, the Beta topside was loaded from the transport vessel onto the platform set up vessel Pioneering Spirit of offshore firm Allseas, which then sailed to the set up location at sea. After completion of preparatory work, Pioneering Spirit precisely positioned the Beta topside on the jacket this week.
Important milestone within the supply of this vital vitality transition venture
Sami Iskander, Petrofac Group Chief Govt: “The protected set up of the Beta topside is a major milestone within the supply of this vital vitality transition venture. Everybody concerned must be happy with this achievement.”
Marco Kuijpers provides: “I’m very happy that the venture was put in safely and I praise Petrofac and Allseas with this. Wind vitality performs an important function within the vitality transition, additionally in business, and I’m proud that TenneT, along with our companions, can contribute to a sustainable future on this method.”
When the wind farm space Hollandse Kust (zuid), is absolutely operational in 2023, it is going to generate an quantity of renewably vitality that’s equal to the annual consumption of greater than two million households. Hollandse Kust (zuid) is the primary subsidy-free wind farm space on the earth.
Renewable vitality from the North Sea to the excessive voltage grid on the Dutch mainland
The inexperienced vitality generated by the wind generators within the North Sea is collected at an offshore transformer station. The voltage is transformed from 66 kV into 220 kV. The electrical energy is then transported to land through cables within the seabed and is landed at {an electrical} substation on the Maasvlakte. At this substation the voltage is transformed into 380 kV. Lastly, the electrical energy is transported to the excessive voltage grid through excessive voltage station Randstad 380 kV Zuidring.
Offshore inexperienced vitality by the top of 2023
By the top of 2023 TenneT could have constructed 3,500 MW offshore grid connections for offshore wind farms within the Dutch North Sea. The primary 1,400 MW has been realised with the supply of Borssele Alpha and Beta in 2019 and 2020. It should now be the flip of Hollandse Kust (zuid) Alpha and Beta this yr, adopted by Hollandse Kust (noord) in 2023. TenneT is utilizing 5 equivalent 700 MW transformer platforms for these wind farms. These platforms are situated near the wind farms and all 5 use the identical sort of 220 kV cable connection to the coast. Such standardisation allows TenneT to finish these initiatives extra effectively, extra rapidly and extra economically.
In direction of 2030, the Dutch and German governments will set new targets for offshore wind. The Dutch authorities lately introduced new areas and targets with a complete put in capability of 20,7 GW round 2030. In Germany, on high of the already elevated ambitions new offshore wind targets might be introduced quickly.
