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 key tasks
Innovation
TenneT presents Hub and Spoke concept for large scale wind energy on the North Sea.
Read moreOur 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 24,500 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.

Meet usSchaltanlage Elsfleth West
The increased infeed of wind energy at and off the North Sea coast makes upgrading of the existing grid structure necessary. The 380 kV Elsfleth/West substation is an important building block in this process.
About the project
The energy transition is presenting Germany with new challenges: power which is generated in decentralised, distributed facilities is increasingly sourced from renewable energies. It is important to link the facilities together intelligently to ensure security of supply. Wind energy in the North is one of the most important sources of renewable energy. Lower Saxony, especially, produces more wind power than any other federal state. The increased infeed of wind energy at and off the North Sea coast makes upgrading of the existing grid structure necessary. The 380 kV Elsfleth/West substation is an important building block in this process.
Security of supply: the nuts and bolts
Security of supply is always in the foreground for TenneT. We can create reliable infrastructures for the increased power infeed from regenerative sources and the transport of energy from and within the region by interlinking our grid expansion with the development of renewable energies.
More uniform utilisation, higher transmission capacity
The 380 kV Elsfleth/West substation is planned to ensure uniform distribution of the load flows across the existing overhead lines in the region, which will ensure a continuous and therefore more secure power flow.
