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).

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.

Security of supply

We strive to ensure a reliable and uninterrupted supply of electricity in our high-voltage grid for some 41 million end users. In doing so, we make every effort to meet our stakeholders' needs by being responsible, engaged and connected.

Leading European TSO

With around 22,000 kilometres of high-voltage lines, we cross borders and connect countries. TenneT ranks among Europe's top five TSOs and works closely with governments, Non-Governmental Organisation (NGOs), suppliers and investors all over the world. Our aim is to ensure that essential high-voltage infrastructure is developed, realised and managed efficiently, now and in the future. This covers onshore and offshore grids, as well as cross-border interconnections. We are keen to pursue the further development of the North West European (NWE) electricity market.

TenneT in the supply chain

TenneT operates as a key player in the electricity supply chain. This chain consists of producers of electricity from both conventional and renewable energy sources, grid companies that transmit electricity (including TenneT), electricity suppliers, customers (industrial and small-scale users) and Pro-sumers (energy consumers acting as producers).

TenneT’s high-voltage grid is connected to regional and local distribution grids managed by various other grid companies (so-called Distribution System Operators, DSOs) and directly to large industrial customers.
