Heijmans and Europoles win provisional Wintrack II TenneT contract

The project is for the design and realisation of the high-voltage pylons and foundations on two grids

High-voltage network manager Tennet has provisionally awarded the contract for the realisation Wintrack II, Noordwest 380kV and Zuidwest 380kV to the Heijmans-Europoles combination. The project is for the design and realisation of the high-voltage pylons and foundations on the Eemshaven-Vierverlaten (Noordwest 380 kV) and Borssele-Rilland (Zuidwest 380 kV West) grids. The contract (design & construct) represents a value of around €200 million.

The project Noordwest 380 kV is for the replacement of the existing high-voltage connection (220 kV) between Eemshaven and Vierverlaten with a 380kV connection, partly in combination with 110 kV. This will make it possible to improve the transport and distribution of electricity from various power plants, (offshore) wind turbine parks and undersea power connections in the north. The Zuidwest 380 kV West project involves the construction of a new connection that will double the transport capacity on the Borssele-Rilland grid, to give the electricity grid additional capacity for power generated by sources such as new offshore wind turbine parks.

This provisional contract is in line with Heijmans’ selective acquisition policy, which is aimed at acquiring large-scale projects in partnerships and the execution of such projects in cooperation with partners that have a proven track record in their field of expertise.

Both projects are part of the current state coordination scheme (rijkscoördinatieregeling). The combination will begin work once the so-called zoning plans associated with the projects have been irrevocably approved. The contract is expected to be granted at the end of January 2017.

Innovative design

Wintrack is a new pylon concept for high-voltage lines. TenneT has already used the concept in the Randstad 380 kV Zuid and Noordring and Doetinchem-Wesel projects. The innovative Wintrack II pylon is partly made of concrete, unlike the Wintrack I pylon which is made entirely of steel. The new pylon also has a sleek profile and is designed to significantly reduce the so-called magnetic field zone. These features mean it is possible to build new 380kV connections above ground with minimal impact on local residents and the landscape.
