TenneT in the supply chain

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) and directly to large industrial customers.

Business model

Virtually all of TenneT's activities are regulated. These activities are governed by relevant legislative and regulatory provisions in the Netherlands and Germany. Regulatory authorities, Autoriteit Consument & Markt (ACM) and Bundesnetzagentur (BNetzA) oversee TenneT's compliance with these provisions. TenneT's regulated activities are managed on country level by two operating segments TSO Netherlands and TSO Germany. 
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). 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.

Non-regulated activities

TenneT is involved in certain limited non-regulated activities, which help to ensure the energy market operates smoothly and efficiently, or are ancillary to it. As such, TenneT holds a 50% interest in BritNed, a merchant cable operator that manages the electricity interconnector between the Netherlands and Great Britain. TenneT also owns 100% of NOVEC and has a 50% stake in Relined; these companies manage infrastructure to send and receive broadcasting and telecom signals. Furthermore, TenneT (indirectly) holds a 17% share in EPEX Spot SE (EPEX), the NWE (including Great Britain) electricity exchange.
