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.
916 megawatt power line to connect three offshore wind farms.
The DolWin2 project sees TenneT building a 135-kilometre direct current connection. With a capacity of 916 megawatts, it can connect the Nordsee One, Gode Wind I and Gode Wind II wind farms to the onshore transmission grid.
These wind farms are situated between approx. 45 and 60 kilometres off the coast. The offshore converter platform DolWin beta was successfully installed in August 2015. The innovative structural design simplified its installation, which did not require any pile driving in the sea floor nor assistance of a crane vessel. The onshore route from the coast to the new converter station Dörpen West in the Emsland district is around 90 km long and was completed in the summer of 2014. In Dörpen West, the direct current is converted into alternating current and fed into the transmission grid via the high-voltage substation. Since the spring of 2016, the connected wind farms can feed power into the grid via the DolWin2 connection.
