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.
Coupling electricity markets is a complex process that requires a step-by-step approach to bring us to our ultimate goal of a single integrated European market.
The Scandinavian countries were among the first in Europe to deregulate their electricity markets and trade electricity across the region in implicit auctions.
The Amsterdam Power Exchange (APX) was the first independent electronic exchange in mainland Europe for day ahead auctions (trading today for electricity delivered tomorrow). The Dutch spot market trading platform is APX Power NL. There are also trading platforms in the UK and Belgium. TenneT Holding BV is the majority shareholder in APX; the rest of the shares are held by Belgian TSO Elia System Operator NV.
TenneT joined forces with Belgian TSO Elia and Germany’s E.ON Netz and RWE Netz, to set up TSO Auction BV, a central auction office for cross-border production capacity. Its activities were transferred to CASC.EU in 2012.
The implicit market coupling of the Netherlands, Belgium and France was an important step towards the integration of the North West European electricity markets.
TSOs in the Netherlands, France, Germany, Belgium and Luxembourg set up CASC-CWE (Capacity Allocation Service Company, Central West Europe) as a joint trading platform to execute explicit long-term auctions (annual and monthly). Its activities have since expanded to include TSOs in Italy, Switzerland and Scandinavia. In 2010, the name changed to CASC-EU.
The Central Allocation Office GmbH (CAO) was founded in 2008 as a single point of registration for capacity auctions in Central Eastern Europe, allocating cross-border electricity transmission capacity in Austria, Czech Republic, Germany, Hungary, Poland, Slovakia and Slovenia
The European Market Coupling Company (EMMC) was founded in Hamburg in 2008 to couple the CWE and Nordic regions. Its first interconnection was between Germany and Denmark in 2009. Subsequently, the Baltic Cable linked Germany and Sweden and the NorNed cable connected Norway and the Netherlands.
The UK joined to the Dutch day-ahead market via the BritNed cable in 2011, bringing Europe a step closer to integrating day ahead markets in Europe.
The day ahead markets in North Western Europe (NWE) were successfully coupled in February 2014, enabling electricity to be traded from France to Finland under a common day ahead electricity price calculation. This laid the foundation for multi-regional coupling and in May 2014, the NWE region was coupled with south western Europe, linking markets and TSOs all the way down to Portugal.
Market Coupling optimizes the efficiency of power trading by allocating cross-border transmission capacity between the different coupled spot markets, while ensuring that the physical limits of the grid are respected. In so doing, market coupling narrows price spreads between national power markets and increases social welfare for the involved countries.
TenneT’s vision is to have a fully integrated electricity market by 2020. This will enable a better flow of electricity across borders, guaranteeing even greater security of supply and making electricity prices across Europe more uniform – and cheaper for end users.
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.
