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.
We are TenneT
Meet usTenneT in the electricity sector
TenneT is the sole transmission system operator (TSO) of the national high-voltage grid of the Netherlands. In Germany, TenneT is the biggest TSO among the 4 TSOs.
Electricity transmission
The electricity supply is transmitted along separate systems in the Netherlands and Germany. TenneT is responsible for connecting electricity producers to the high-voltage grid. We also ensure the transmission of electricity across this grid. TenneT does not distinguish between producers and is obliged by law to connect all parties to the grid, from coal-fired power plants and wind farms to small-scale horticulturalists.
TenneTs tasks
TenneT is the sole transmission system operator (TSO) of the national high-voltage grid of the Netherlands. In Germany, TenneT is the biggest TSO among the 4 TSOs, connecting the North Sea with the Alpes.
We are therefore responsible for a number of additional tasks that may not be performed by other grid operators in the Netherlands. This includes system services (e.g. maintaining the balance between electricity supply and demand) and ensuring the security of supply. TenneT also acts as a market facilitator, ensuring that all players in the industry have access to the market.
In Germany, TenneT performs the same tasks, alongside three other TSO's, who each cover their own designated areas. What makes TenneT's role in Germany particularly challenging is its obligation to connect and transport electricity generated by offshore wind farms to the onshore high voltage grid.
Cooperation
In order to perform our diverse and various tasks, TenneT works closely together with the following parties:
- ACM (NL) and the BNetzA (DE)
- Grid operators
- Balance Responsible Parties (BRPs)
- Electricity producers
- Traders in electricity
- Parties with metering responsibility (NL)
- TSO organisations (ENTSO-E members)
