Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Our grid

TenneT manages the high-voltage grid in the Netherlands and large parts of Germany. TenneT transmits electricity at 110,000 volts (110 kV) and higher. With around 22,000 kilometres of high-voltage lines, we cross borders and connect countries.

Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

Net op zee Hollandse Kust (zuid)

The grid connection of the future 'Hollandse Kust (zuid)' offshore wind area will be 1400 megawatts (MW), consisting of two connections each of 700 MW.

About the grid connection

The Hollandse Kust (zuid) grid connection will comprise two platforms that TenneT will build (called Alpha and Beta). Each platform will process the electricity generated by two wind turbine sites, and will provide 700 MW via two cables (alternating current). One of the two offshore grid connections is located in a zone that has not yet been officially designated for wind energy development. The realization of that 700 MW connection (i.e. the offshore platform and the associated cables) therefore depends on the partial revision of the National Water Plan. From the platforms there will be a total of four alternating current cables that run to a high-voltage substation on the mainland.

The route is still to be determined. Onshore they will be connected to the South Ring of the Randstad 380 kV line. Hollandse Kust (zuid) Alpha will go into service in 2021 and Hollandse Kust (zuid) Beta in 2022.

Programme offshore grid

By means of the National Energy Agreement, the Dutch government wants to achieve a substantial increase in the share of wind energy in the Netherlands’ energy mix. To increase offshore wind energy capacity, the government has designated three zones in the North Sea for the development of new wind farms.
