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 key tasks
Innovation
TenneT presents Hub and Spoke concept for large scale wind energy on the North Sea.
Read moreOur 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 23,500 kilometres of high-voltage lines, we cross borders and connect countries.
Offshore Outlook 2050
Already by 2030, the originally planned capacity of 15 gigawatts of offshore wind energy will increase to 20 GW.
To Offshore Outlook 2050Electricity 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.
Transparency data
We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E.
To transparency pagesE-Insights
Our vision is to be one of the most transparent Transmission System Operators (TSO) in Europe and thereby creating value for society. In this Energy Insights section we present selected energy related topics and show data, information and valuable insights.
Company
TenneT is a leading European electricity transmission system operator (TSO), with activities in the Netherlands and in Germany. We strive to ensure a reliable and uninterrupted supply of electricity in our high-voltage grid for some 42 million people.

Meet usProgramme 2023
Between now and the end of 2023, TenneT will realise 3,500 megawatts (MW) of offshore connections, in a standardised concept of 700 MW per connection. This will make an important contribution to the Energy Agreement signed in 2013.
What
The offshore grid transports wind energy generated offshore to the mainland’s electricity grid. This occurs from three wind energy areas in the North Sea. These are the Borssele, Hollandse Kust (south) and Hollandse Kust (north) wind energy areas. The government has designated these areas for generating more sustainable energy. Together the wind energy areas yield enough electricity for 5 million households.

- 2021 700 MW Hollandse Kust (zuid) Alpha
- 2022 700 MW Hollandse Kust (zuid) Beta
- 2023 700 MW Hollandse Kust (noord)
Offshore platforms
Platforms make up an essential part of the offshore grid. TenneT is building 5 identical platforms for the 2023 programme, to transport a total of 3,500 MW of wind energy to the mainland.
Standardising these platforms will produce a substantial reduction in the costs of development, construction and maintenance.
