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.

Transparency data

We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E. 

To transparency pages

Our vision is to be one of the most transparent Transmission System Operators (TSO) in Europe and thereby creating value for society. In this Energy Insights section we present selected energy related topics and show data, information and valuable insights.

Grid development

To make sure TenneT can deliver a continuous power supply during the switch to renewable energy, we need to invest heavily in developing, reinforcing and expanding our grid in the Netherlands and Germany over the next ten years.

A reliable, modern and efficient grid

Our high voltage grid transports electricity over large distances, from producers to centres of consumption. These high voltage lines are the backbone of TenneT’s electricity supply system. TenneT operates an efficient, modern grid that delivers high quality against low transmission costs. The aim of our expansion projects is to continue providing sufficient grid capacity, both today and in the future. In this way, we ensure that critical requirements can be met and that the grid can reliably match supply and demand on the electricity market.

We are also preparing the grid for further changes in the energy market. We make it possible for locally generated energy from wind, solar and other energy plants to be fed into the grid. In order to avoid power outages, we are replacing and reinforcing old connections, building new ones, and constructing additional high-voltage stations.

Through expansions, upgrades and continuous maintenance, we are developing an infrastructure that is prepared for its future tasks.

Dutch grid 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.
