In the energy agreement it was agreed that by 2030 32% of the Dutch energy supply should come from renewable energy sources. Four large offshore wind farms will therefore be constructed off the coast of Zeeland. The power generated there will come ashore in Borssele via OHVS Alpha and Beta, two mega large offshore substations.
VolkerWessels companies Visser & Smit Hanab and Volker Energy Solutions (formerly Joulz Energy Solutions, part of Visser & Smit Hanab since the end of 2018), are working in Borssele on behalf of TenneT on the expansion of the existing onshore high-voltage substation. All this to increase the capacity of the grid so that the enormous amount of wind energy from the offshore wind farms can be brought ashore via the Offshore High Voltage Stations Alpha and Beta. Visser & Smit Hanab laid the high-voltage cables at the new transformer substations and the connection cables to the existing high-voltage substation. Once the cables had been laid, they were connected to the steel structures designed and installed by Volker Energy Solutions.
TenneT and Visser & Smit Hanab have a framework contract in which they are preferred suppliers for the activities in the South region (Zeeland, Brabant, Limburg). The project in Borssele was carried out as part of this framework contract. Thanks to good coordination with TenneT and all sub-contractors, the project was completed safely and on schedule.
