Costs of a grid connection

Costs are obviously payable for a new grid connection. ACM issues guidelines for our pricing in the Electricity Tariff Code.

Costs for installing a new connection

TenneT charges the connection tariff (or initial investment costs). These costs vary, because every connection has to be customised.

By way of indication, here is an approximate overview of the costs (2018 price levels) of bays in an outdoor configuration, for the most frequently occurring connections:

  • 110 kV and 150 kV: €1,5 - 2,5 million
  • 220 kV and 380 kV: €3 - € 5 million

Monthly cost of upkeep

Once the connection is ready

  • the periodical connection charge. This is an annual fee for managing and replacing the connection;
  • the transmission tariff, which covers TenneT’s transmission of electricity. These costs consist of a fixed amount for costs unrelated to transmission (e.g. for invoicing, administrative work and similar) and a variable amount for transmission-related costs, charged as an amount per kilowatt. ACM sets the tariffs from year to year on the recommendation of TenneT. The transmission tariffs of TenneT are downloadable from the ACM (Dutch only) website.

Charge for stopping the connection

Tennet will charge once

  • a non-recurring contribution towards removing the connection. Again, these costs vary according to the type of connection. TenneT will charge you these costs in the event of the breaking or expiring of your connection and transmission agreement.

Doing business with TenneT

Each of these managers is responsible for a specific region of the country or area of attention. You can also contact us at any time via the TenneT Customer Care Center.


Digital portal MyTenneT

TenneT also operates an online portal called My TenneT to enable you to take care of TenneT matters quickly and conveniently. The digital dashboard consists of various elements for connected parties and for Balance Responsible Parties and Metering Responsible Parties. It is accessible in Dutch and English versions via the TenneT website. 

Obligations for connected parties

Connected parties are obliged by law to inform TenneT daily about their planned and their actual electricity production, consumption and transmission needs. This is necessary to maintain the balance in the high voltage grid: TenneT keeps electricity supply and demand in equilibrium, 24 hours a day, 365 days of the year. Connected parties may contractually assign these obligations to recognised parties if they wish.
