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 23,500 kilometres of high-voltage lines, we cross borders and connect countries.
Offshore Outlook 2050
Already by 2030, the originally planned capacity of 15 gigawatts of offshore wind energy will increase to 20 GW.
To Offshore Outlook 2050Electricity 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 pagesE-Insights
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.
Company
TenneT is a leading European electricity transmission system operator (TSO), with activities in the Netherlands and in Germany. We strive to ensure a reliable and uninterrupted supply of electricity in our high-voltage grid for some 42 million people.
