Welcome to TenneT

We take electricity for granted in our everyday lives. Without thinking about it, we turn on the lights or the coffee machine. But these routine actions would not be possible without having somebody to supply the power. The Netherlands has an effective and reliable electricity supply system.

As the Dutch Transmission System Operator, TenneT TSO has a duty to monitor the continuity and security of the electricity supply in the Netherlands, 24 hours a day, 365 days a year.

In addition to administering the national transmission grid and safeguarding the reliability and continuity of the Dutch electricity supply, TenneT provides services and performs duties aimed at developing the electricity market and ensuring that it functions properly. We also provide services that support free-market operation and further the development of a sustainable energy supply system. On this website you will find comprehensive information about TenneT, who we are, what we do and how you can contact us.
