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 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 23,000 kilometres of high-voltage lines, we cross borders and connect countries.
A secure and continuous supply of electricity is the key objective of our operations. TenneT transmits electricity at 110,000 volts (110 kV) and higher. In Germany, the operators of the high-voltage grids, i.e. the 220 and 380 kV grids, are designated as Transmission System Operators.
