About TenneT tariffs

The tariffs differ in the Netherlands and Germany due to different regulations.

The Netherlands

Our Dutch tariffs are set by the Dutch energy regulator ACM (Autoriteit voor Consument en Markt). Each year, we submit a proposal to the ACM of what we intend to charge for our services that year, which we calculate according to the regulator’s Tariff Code.

This is evaluated by the board of the ACM, which then sets the actual fee in its Tariff Decision.

Two types of tariffs apply. These are:

  • Connection tariffs
  • Transport tariffs
