New high-voltage substation for TenneT at Maasvlakte

On behalf of SPIE, we are carrying out the civil engineering works for TenneT at Maasvlakte in Rotterdam. The project includes two GIS halls with basements (15 x 65 metres) and a connecting structure (90 x 23 metres) as well as associated installations. The buildings are 21 metres high and form part of the new Amaliahaven high-voltage substation. ‘The Beast’ was retrofitted for electric power especially for this project.

Unique converted electric crane

TenneT stipulated that the works be carried out using electric equipment only. We therefore converted The Beast—as we affectionately call our 12-tonne Sennebogen crane—to full electric operation. With a modern electric motor and a substantial battery pack, we now have a unique converted electric crane that is fully ready for zero-emission construction.

Meeting strict CC3 requirements through digital assurance

Constructing the 380-kV Amaliahaven substation is a significant challenge to say the least. The project is subject to strict CC3 requirements to ensure the structure can withstand extreme conditions and very heavy loads. In addition, every part of the construction process must meet the highest standards of safety and sustainability. For quality assurance, we use the Dalux digital platform to record and manage drawings, inspection plans, reports, workflows and processes in one place. This transparent, structured approach enables us not only to demonstrate compliance with all requirements but also to communicate clearly with TenneT.

Extra capacity is essential

Electricity demand in Zuid-Holland is increasing rapidly and will only continue to grow. As the existing Maasvlakte station on Coloradoweg can no longer accommodate new connections, a new station is needed to future-proof the network. With the Amaliahaven substation, TenneT can integrate offshore wind energy into the national high-voltage grid, supplying hydrogen plants and other energy-intensive industries at Maasvlakte. In line with Cordeel Nederland’s mission, we are proud to contribute to the energy transition by not only strengthening the electricity grid but also using electric equipment only.
