Major construction project with all-electric equipment

TenneT Amaliahaven Rotterdam

Commissioned by SPIE, C-concrete took care of the delivery of prefab sandwich panels for TenneT for two GIS halls with basement (15 x 65 meters) and a coupling building (90 x 23 meters), including associated installations on the Maasvlakte. The buildings are 21 meters high and part of the new Amaliahaven high-voltage substation. Especially for this project, C-concrete electrified “The Beast.

Unique converted crane

Tennet set the condition that the work be done electrically. Therefore, we converted The Beast, as we affectionately call our huge 120-ton Sennebogen crane, to electric. Thanks to the modern electric motor and ample battery pack, we now have a unique converted electric crane, completely ready for emission-free construction.

Stringent CC3 requirements digitally secured

The construction of 380 kV high-voltage substation Amaliahaven can definitely be called challenging. The strict CC3 requirements apply, which guarantee that a structure can withstand extreme conditions and very heavy loads. In addition, every part of the construction must meet the highest safety and sustainability standards. For quality assurance, we use the digital platform Dalux to centrally record and manage drawings, inspection plans, reports, workflows and processes. Thanks to the transparent and structured working method, we can not only demonstrate that all requirements have been met, but also clearly communicate this to TenneT.

Additional capacity needed

In South Holland, the use of the high-voltage grid is increasing rapidly, and this growth will continue in the coming years. Since the Maasvlakte substation on Colorado Road cannot facilitate new connections, a new substation is necessary to make the grid future-proof. With Amaliahaven substation, TenneT is creating the possibility to add energy from offshore wind farms to the national high-voltage grid and thus supply hydrogen plants and other energy-intensive companies on the Maasvlakte with power. We are proud that, fully in line with the mission of Cordeel Netherlands, we are making a double contribution to the energy transition with this project: reinforcing the electricity grid, and fully electric on top of that.
