ABB’s high-voltage hybrid switchgear to strengthen transmission grid in the Netherlands

ABB’s hybrid switchgear solution will help to increase the reliability in two substations for the Randstad 380 kV North Ring high-voltage transmission line in the Netherlands.

TenneT, a leading European electricity transmission system operator (TSO) in the Netherlands and in a large part of Germany is constructing the new North Ring transmission line that will include two new 380 kV substations, Vijfhuizen and Beverwijk in the Netherlands.

Electricity grids in the Netherlands have reached the limits of its capacity and must be upgraded to keep pace with the developing energy landscape. The North Ring is part of the expansion of the national transmission network to meet the increasing electricity demand. Once in operations, it will guarantee the security of electricity supply in the Ranstad region and increase transmission capacity in the future.

ABB's ELK hybrid switchgear 420 kV technology will be installed in Beverwijk and Vijfhuizen substations. This hybrid solution is a simplified gas-insulated switchgear (GIS) that combines the advantages of encapsulated technology with the simplicity of air-insulated switchgear (AIS) that offers high reliability and greater flexibility for the substation design. With up to 70 percent less space requirement compared to AIS, it also offers quick and easy installation. In addition, ABB will also supply a 170 kV GIS to the Vijfhuizen substation to increase the stability of the existing 150 kV grid that is used for regional electricity distribution.

Beverwijk and Vijfhuizen substations are scheduled to be connected to the national grid in the middle of 2015. ABB has delivered similar well proven hybrid switchgear solutions to TenneT such as UW Simbach and UW Karben in Germany.
