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 around 23,000 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.
Clean wind energy from the eastern North Sea
HelWin2 is a high-voltage direct current (HVDC) transmission system with a capacity of 690 MW. This project is the third connection of TenneT in the eastern North Sea. The line runs from the HelWin beta converter station 85 kilometres as submarine cable to the landing point in Büsum and from there 45 kilometres as underground cable to the converter station in Büttel in Schleswig-Holstein.
The offshore converter platform HelWin beta is a subsidiary platform of HelWin alpha, the heart of the grid Connection HelWin1.
There are only about 20 metres between the two platforms. Both platforms are directly connected by a bridge. This means that the helicopter deck and the crew accommodation can be shared for the employees at sea. This is an innovative and cost-saving concept because it makes use of technical and logistical synergies.
