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.
165 kilometres of cable for a grid connection with a capacity of 800 MW
DolWin1 is a 165 kilometres long direct current (DC) grid connection with a capacity of 800 megawatt (MW), which TenneT put into service in July 2015. In the offshore platform DolWin alpha, the alternating current (AC) generated by the wind farms is converted into DC power and transmitted via 75 kilometres of subsea cable and 90 kilometres of land cable to the corresponding converter station in Dörpen West in Emsland. In Dörpen/West the DC power is re-converted into AC power and fed into the onshore transmission system.
