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).
TenneT presents Hub and Spoke concept for large scale wind energy on the North Sea.
Read moreTenneT 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 over 22,500 kilometres of high-voltage lines, we cross borders and connect countries.
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.
We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E.
To transparency pagesOur 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.

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.
Power grid failures can disrupt the supply of electricity, impacting people and businesses. TenneT works hard to ensure the reliability of its high-voltage grid.
So far, the security of our supply is among the best in Europe, with 99.99% grid availability.
Although we make every effort to prevent power failures, interruptions to the electricity supply can still occur. When they do, we attempt to fix them as soon as possible. In some cases, however, the problem is so complicated that the power outage lasts longer than expected.
Should you experience any long-term inconvenience due to a failure in the TenneT grid, you will be appropriately compensated in accordance with the applicable legislation. Claims for compensation must be submitted to the distribution network operator in your region.
We publish real time information on interruptions of power supply:
The upkeep of the high voltage network is one of TenneT’s most important tasks. It reduces the risk of disruptions and ensures the security of the electricity supply.
