TenneT is a leading European electricity transmission system operator (TSO), with activities in the Netherlands and Germany. We are committed to achieve a reliable and uninterrupted supply of electricity through 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.

TenneT is a key player in the electricity supply chain. This chain consists of producers of electricity from both conventional and renewable fast-growing energy sources, grid companies that transmit electricity (including TenneT), electricity suppliers, customers (industrial and small-scale users) and prosumers (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). It is also directly connected to large industrial customers. For maps of our onshore and offshore high-voltage grid, click here.

Nearly all of TenneT’s activities are regulated and subject to relevant legislative and regulatory provisions in the Netherlands and Germany. Regulatory authorities Autoriteit Consument & Markt (ACM) and Bundesnetzagentur für Elektrizität, Gas, Telekommunikation, Post und Eisenbahnen (BNetzA) oversee TenneT’s compliance with these provisions. Our key tasks are based on our role as grid operator under the Dutch ‘Elektriciteitswet’ (E-wet) and the German ‘Energiewirtschaftsgesetz’ (EnWG). These key tasks are:

  • To ensure a secure and continuous supply of electricity as the key objective of our operations.
  • To provide transmission services by transporting electricity along the high-voltage grid from where it is produced to where it is consumed.
  • To provide system services to guarantee the flow of electricity in the Netherlands and large parts of Germany.
  • To facilitate a smooth-running, liquid and stable electricity market and to support the large-scale transition to renewables.

In addition to these regulated activities, TenneT is involved in a limited number of non-regulated activities. These either help to ensure that the energy market operates smoothly and efficiently, or are ancillary to it. For a full overview of our group structure click here.
