Project description:

NTT Ltd. operates a data centre (NTT AMS 1) near Schiphol Airport in Rozenburg, the Netherlands. Currently this data centre is powered by a 20 kV cable connection. Due to a growing power demand caused by an expansion of the data centre this connection must be upgraded to a 150 kV cable connection from TenneT’ TSO 380 kV / 150 kV substation Vijfhuizen.

The length of the new 150kV cable connection is approximately 14,5 km of which 9,4 km is installed in total twenty HDD’s.

Activities of Energy Solutions:

Energy Solutions provides expertise in the field of underground high-voltage cables for this project. In collaboration with ATRON-Engineering, the following aspects are realized:

• Feasibility study on the 150 kV cable connection between TenneT 150kV substation Vijfhuizen and the project location. Three alternative cable routes were proposed and for one option a basic- and detailed design was made.
• Evaluation of a second or redundant 150kV cable connection between TenneT 150kV substation Rozenburg Zuid and the project location
• System design of the 150 kV cable connection
• Civil route engineering incl. HDD engineering and soil investigations
• EMC influence study
• Permit application and right of way agreements, soil investigations etc.
• Drafting the technical aspects of the contract, civil and cable tender documents for the 150 kV cable connection.
• Tendering of the works for the cable supply and installation.

During the project execution phase:
