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 22,000 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 pagesTenneT 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.
155 kilovolt AC grid connection
In addition to alpha ventus, Riffgat is the second offshore grid connection completed by TenneT using three-phase alternating current (AC) technology. This grid connection consists of an 80 kilometres long 155 kilovolt (kV) connection which is integrated into the 220 kV grid at the substation Emden/Borssum. For this purpose the existing substation has been expanded. Riffgat is located within Lower Saxony's twelve nautical mile zone and about 15 kilometres to the north-west of the East Frisian North Sea island of Borkum. As a result, the wind park is located 50 kilometres from the mainland and therefore quite near to the coast. Due to this small distance to the mainland and an installed capacity of 113 MW the most efficient method to realise the project from a technical as well as from an economic perspective is a three-phase AC technology.
The In February 2014, the wind farm has been connected to the transmission grid.
