The framework contracts will last for three years with an option to extend for additional two years.

The consortium, which will be joined by partners Roos+Bijl and Joulz, will support TenneT as preferred supplier for connections and approved supplier for stations as the electricity transmission system operator (TSO) intends to integrate increasing renewables generation on the network and systems.

TenneT investment program will also expand the Netherlands’ connections with neighbouring nations.

Under the agreement, the consortium will provide services in the areas of spatial integration of connectors and stations, environmental impact, soil surveys, permits, feasibility studies, high-voltage engineering, architectural design and supervision.

DNV GL director for energy in Benelux Jacob Ruiter said: "As a longstanding partner of TenneT, DNV GL (formerly KEMA) – as a consortium member – delivers its expertise to support TenneT’s ambitions in integrating more renewables and securing a reliable energy supply in the future."

TenneT is European electricity TSO in the Netherlands and in a large part of Germany.
