International connections

TenneT seeks to be a key player in the North West European energy market. We continue to work closely with our European partners to further integrate the electricity market, thereby assuring a reliable and secure electricity supply at competitive prices. Connecting countries and regions creates an international chain of high-voltage grids that makes it easier, cheaper and more efficient to transmit electricity across borders and to more effectively balance international supply and demand.

Cross-border connections

We have, or are in the process of realising the following cross-border connections with our international partners: 

  • NorNed cable from the Netherlands to Norway (operational since 2008)
  • BritNed cable from the Netherlands to the United Kingdom (operational since 2011)
