Our key tasks

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).

Our grid

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 22,000 kilometres of high-voltage lines, we cross borders and connect countries.

Electricity market

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.

Electricity market

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.

Key role for TSOs

TenneT and other TSOs play a key role in this process, since market integration requires sufficient cross-border transmission capacity. Together with its project partners, TenneT is taking the lead in establishing a single European energy market, for instance by facilitating the introduction of flow-based market coupling. This system is based on close collaboration between the power exchanges and TSOs of a large number of countries, and helps to ensure that the production facilities and the available transmission capacity in those countries are used as efficiently as possible. 

Enabling the energy transition

Another important development is the so-called energy transition. Conventional coal- and gas-fired power plants are gradually being replaced by wind and solar energy. In addition, more and more electricity is being produced decentrally or even locally. These developments pose their own challenges which require new technologies and market models. TenneT plays a prominent role in these debates as well.
