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 23,000 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.
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 41 million people.

Dutch offshore grid
The Netherlands is heading towards a sustainable energy supply. Wind is an important source of sustainable electricity. Wind on land, and especially: wind at sea. The Dutch government has appointed TenneT as the offshore grid operator. This means it’s TenneT’s responsibility to ensure that offshore wind farms are connected to the onshore grid via the offshore grid to enable the use of the energy that is generated at sea. Construction of the offshore grid contributes to TenneT’s ambition to be a driving force behind the energy transition.

Fewer costs, less inconvenience
Several wind farms are grouped together in a wind energy area. The offshore grid ensures that these wind farms are combined as much as possible for connection to the national high-voltage grid. This means fewer cables and shore points are needed. That reduces costs significantly and is less disruptive for the environment.
