3 TenneT at a Glance Taking Power further We connect 41 million end-users in the Netherlands and Germany. We guarantee the stability of over 22,500 kilometres of high-voltage connections. Our leading technology drives the integration of renewable energy. We are Europe s first cross-border grid operator. We maintain security of supply at an extremely high level of 99,9999 %. TenneT is a leading TSO in Europe February 2018 TenneT at a Glance 3
