150MW 150kV Substation Design Review 

Electricor completes Design Review of Proposed 120 MW HV Data Centre Substation in Amsterdam Schiphol 

We were pleased to be asked to carry out a Design Review of the HV/MV Systems for a multinational Data Centre provider 

The review was written remotely by Ian Watson MIET based in the UK with help from our local Dutch Partner in Amsterdam 

Our client wanted ensure the design was robust and took account of local standards, and that there were no connection issues into the TenneT 150kV grid substation.

The 120 MW Substation was in two parts 150kV dual supply GIS switchgear three bus bar sections to ensure resilience, two feeders and a swing section. These fed three 150kV to 20 kV 64MW transformers. Feeding three 20kV bus sections and 22 outgoing ways to feed future Data Centre Expansion in the Amsterdam area.

We also reviewed all the interconnections and controls into the Grid Authority Tennet 150kV Substation, confirmed or made further recommendations for changes 

To connect to the Dutch Grid, Dutch Electricity Grid Codes apply, these are detailed with respect to Articles which are extensive, with requirements from electromagnetic compatibility to metering accuracy. We provided  recommendations against each of these. 

The Review produced two reports 

Red Flag report identifying initial issues that needed to be resolved immediately.

Final Report 

Design Issues / improvements to design - We identified several areas where improvements could be made/changes needed

Grid Authority interfaces - We provided analysis and recommendations 

Compliance with Dutch NEN standards - How to achieve 

Compliance with Dutch Legislation - Applicable Legislation and measures needed

Compliance with Dutch Grid Codes - Recommendations as to how to comply 

Recommendations / Changes to the 150kV connection into the Grid Authority substation

The reports were required quickly to avoid delays to the project, the Red Flag report being delivered in 3 weeks and the final report within 8 weeks.
