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.

Tariffs

The TenneT tariffs exist of two components: the connection and transport tariffs.

Tariffs in the Netherlands

Parties connected to the national grid in the Netherlands (regional grid administrators, producers and consumers) pay a connection fee to TenneT. This covers the costs associated with the installation, maintenance and replacement of a connection to the grid.  

Connection tariffs

The connection tariff comprises two components:

  • initial connection tariff
  • periodic connection tariff

Initial connection tariff

The initial connection tariff covers the costs of creating the grid connection. It varies as connections to the high-voltage grid are tailor made.

Periodic connection tariff

The periodic connection tariff covers the costs of maintaining and, if necessary, replacing the connection. Parties with multiple connections receive a separate invoice for each one. The periodic connection tariff is a fixed amount that is updated once a year.

Transmission services tariffs

Every party that is connected to the national high ?voltage grid (regional grid administrator, producer or large industrial consumer) pays TenneT a transmission tariff for each connection it uses. The transmission tariff covers the costs of the transmission service.

Types of transmission tariffs

There are two types of transmission tariffs:

  • the non-transmission-related consumer tariff (in Dutch: TOVT);
  • the transmission-related consumer tariff (in Dutch: TAVT).

Non-transmission-related consumer tariff (in Dutch: TOVT)

The TOVT tariff covers the costs that are not directly related to the transmission of electricity. These are, for example, the costs of the administrative processing of metering data, the administration of the register of connections, and the billing costs.

Transmission-related consumer tariff (in Dutch: TAVT)

The TAVT tariff covers the costs of the transmission of electricity. This tariff consists of a unit price per kilowatt (kW). Depending on the number of hours during which the connected party uses the transmission grid (= operating time), a higher or lower tariff will apply.

TenneT charges the TAVT tariff to large industrial consumers and regional grid administrators directly connected to the Dutch high-voltage grid.

Tariff decisions

The transmission-related consumer tariff (TOVT) and the non-transmission-related consumer tariff (TAVT) are listed in the Tariff decisions below.
