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.

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 usWestküstenleitung
The new 380 kV west coast line is an important project for the energy transition and should in future collect the wind power produced on the west coast and transport it to the south.
About the project
Almost 1500 wind turbines with a total output of 3000 megawatts are already turning on the west coast of Schleswig-Holstein. This is more than twice than that ever produced by a nuclear power plant like Brokdorf or Brunsbüttel.
The renewably generated coastal electricity is extremely important for the success of the energy transition in Germany. However, a majority of this energy must be transported to where it is needed in the large consumption centres in southern Germany. This will be especially true after the departure from nuclear power because, as of 2022, electricity will no longer be supplied from nuclear power plants.
The existing power grid is not designed for transporting this coastal electricity. New, high-capacity lines must therefore be constructed. The new 380 kV west coast line is an important project for the energy transition and should in future collect the wind power produced on the west coast and transport it to the south.
