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.
Wind turbines and solar panels are the physical signs of consumers’ growing desire for clean, renewable energy.
Read moreTenneT 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.
900 MW grid connection for offshore wind farms
The Dolwin3 project establishes a 900 megawatt (MW) direct current (DC) grid connection for wind farms in the south-western part of the German North Sea. DolWin3 is the third grid connection project in the DolWin cluster. A high-voltage direct current (HVDC) transmission system line connects the offshore converter platform DolWin gamma with the corresponding onshore converter station in Dörpen/West. The offshore converter station is used to convert the alternating current (AC) generated by the connected wind farms into DC. The DC power runs via subsea and land cables to the converter station onshore, where it is re-converted into AC. This is also the grid junction point which makes the connection to the German transmission grid. The connection is expected to be completed in 2018.
