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.
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 42 million people.

Meet usElectricity producers
Electricity is produced from natural gas, coal and sustainable sources.
Netherlands
Electricity in the Netherlands is produced mainly from natural gas and coal. There are also a number of producers that generate electricity from sustainable sources such as wind, solar, biomass and ambient heat,although on a smaller scale.
The government has appointed TenneT as the operator of the Dutch offshore grid. As the offshore grid operator, TenneT can realize its ambition to facilitate the transition to a more renewable energy supply as laid out by the government. Read more about these projects.
Germany
In Germany, TenneT is contributing to the sustainable energy transition ('Energywende') by facilitating the connection of offshore wind farms in the North Sea to the onshore high-voltage grid.
