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).
TenneT presents Hub and Spoke concept for large scale wind energy on the North Sea.
Read moreTenneT 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 over 22,500 kilometres of high-voltage lines, we cross borders and connect countries.
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.
We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E.
To transparency pagesOur 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.
Wind turbines and solar panels are the physical signs of consumers’ growing desire for clean, renewable energy.
Read moreTenneT 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 41 million people.
The BritNed cable connects the Dutch and British energy markets.
This two-way 1,000 MW high-voltage direct current connection has a length of 260 km and runs from the Isle of Grain (in Kent) to Maasvlakte (near Rotterdam). The operational and technical management of the cable is in the hands of BritNed Development Ltd, a joint venture of British energy company National Grid and TenneT subsidiary NLink International.
This connection is part of a major Anglo-Dutch investment programme to ensure continuing security and diversity of supply and stimulate the use of sustainable electricity. The interconnector also contributes to a more open electricity market, providing greater import and export opportunities for the future.
Electricity has been traded on the BritNed-cable since 2011. Market participants access the interconnector capacity through a combination of explicit and implicit auctions. Power flows are driven by factors such as supply, demand and prices in each market. The implicit auctions are facilitated by the APX energy exchange, now merged with EPEX SPOT. Explicit auctions are carried out via BritNed Development’s own auction system, Kingdom®. This approach gives market parties more choice in how they bid on capacity, contributing to greater transparency on European electricity markets.
BritNed is a commercial interconnector, which means it is funded and operated independently from our regulated business. TenneT and National Grid are jointly responsible for the investment and the risks.
The exchange of power enabled by NordLink will increase security of supply for the German and Norwegian grid and will allow exchange of renewable energies, especially hydroelectric power and wind power, between both countries. In addition it will give more stable electricity prices on both sides and, further on, also will facilitate European market integration.

The Dutch and Norwegian electricity grids have been interconnected by the NorNed cable since 2008. The NorNed cable is 580 km long and has a capacity of 700 MW, making TenneT and our Norwegian counterpart Statnett the joint owners of the world’s longest subsea high-voltage direct current cable link.

The COBRAcable will have a capacity of approx. 700 MW, will be around 325 kilometres long, and will run from Eemshaven (the Netherlands) to Endrup (Denmark) via the German sector of the North Sea. Two onshore converter stations – one in the Netherlands and one in Denmark – are needed to connect the cable to the existing grids.
