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 around 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.

Grid expansion

To be able to transmit all the electricity generated by these new power plants, TenneT is carrying out a large-scale expansion programme.

Increased transport capacity in the Netherlands

The number of electricity producers connected to the Dutch grid has grown significantly since 2006. The boom was initiated by the Dutch greenhouse industry, which deployed over 2,000 MW in new small-scale combined heat and power (CPH) plants in the period to 2010. Several large power plants were also constructed in recent years, increasing the installed production capacity by more than 10,000 MW in 2014 (a rise of over 40%). This is more than enough to meet Dutch domestic demand and exports until far beyond 2020. It is therefore unlikely conventional production capacity will be expanded any more in the next five to 10 years.

To be able to transmit all the electricity generated by these new power plants, TenneT is carrying out a large-scale expansion programme. This mainly  involves constructing new 380 kV connections in the Randstad area (Amsterdam, Rotterdam, Utrecht and The Hague) and in the north and southwest of the country.

Transition to renewable energy

To enable the transition to renewable energy, in line with Dutch government sustainability targets, TenneT has started preparations to build an offshore high voltage grid (3.500 MW) along the Dutch coast, facilitating the connection between offshore wind farms to the onshore high voltage grid. This is likely to be finished by 2023.
