Connecting to the Dutch high-voltage grid

The energy transition is driving new dynamics in the energy sector Europe-wide. This has prompted numerous organisations to consider entering the Dutch energy market. As a regulated organisation, TenneT has been assigned clearly defined statutory duties and responsibilities. Against this backdrop, we are committed to serving you to the best of our ability.

TenneT in a nutshell

TenneT manages the high-voltage grid in the Netherlands and large parts of Germany

TenneT manages the high-voltage grid in the Netherlands and large parts of Germany. From the places where electricity is generated, we transmit it to end-users over 24,500 kilometres of high voltage lines and other electricity infrastructure. Our onshore and offshore cross-border connections form an indispensable link between electricity producers and consumers in the Netherlands and a large part of Germany.

New connections

In the case of a new connection, TenneT will discuss the possibilities with you, and together we will explore, if necessary with the regional grid operator, what the best connection option is for your particular situation.

We will then produce a technical plan for this, accompanied by an offer. After the order has been placed, TenneT will create the connection. As soon as the connection is delivered, it will be put into service. On average it takes 12 to 18 months to create a new connection to the high-voltage grid (in a situation where expansion of the grid is unnecessary).
