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.

PROMOTioN and MIGRATE

TenneT is participating in two major European research programmes: PROMOTioN and MIGRATE. These programmes were initiated in response to new challenges related to the development of offshore power grids and the increasingly important role of solar and wind energy. By participating in the PROMOTioN and MIGRATE programmes, TenneT wants to anticipate these developments.

Collaboration

TenneT conducts research in partnership with other TSOs. The research will help us to achieve our aims of safeguarding the security of supply and facilitating the transition to a sustainable energy supply. The TSOs will contribute their practical experiences, while universities, research centres and test laboratories will contribute to the performance of the research.

About MIGRATE

Project Migrate

MIGRATE: Increase in solar and wind energy presents new challenges

In the future, several areas of the pan-European high-voltage grid will be operated with high levels of solar and wind energy production during certain periods. Electricity-generating and electricity-consuming units will increasingly be connected to the grid using power electronics. This will lead to technical challenges due to a lack of rotational inertia in the power plants, which ensures the required stability at 50 Hz. The MIGRATE research programme (‘Massive Integration of Power Electronic Devices’) is aimed at developing solutions to these challenges relating to grid stability, quality of supply, control, and grid security.

The TenneT-led consortium established for the MIGRATE programme consists of European TSOs from Estonia, Finland, France, Greece, Germany, Iceland, Ireland, Italy, the Netherlands, Slovenia, Spain and the UK, as well as three manufacturers (Alstom, Enercon and Schneider Electric) and a number of universities and research centres.
 

PROMOTioN: Offshore HVDC grids

As wind energy becomes increasingly important to the European energy supply, more connections will need to be constructed to link offshore wind farms to the onshore grid in various countries. PROMOTioN (‘Progress on Meshed HVDC Offshore Transmission Networks’) is a four-year research programme aimed at developing and demonstrating three key technologies. The intention is to produce an ‘offshore grid’ development plan for 2020 and beyond, with due attention for an optimized regulatory and financial framework.

One of the objectives of the research project is to encourage knowledge-sharing on this topic. To that end the PROMOTioN website was created.
