We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).
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
- 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: approx. €1.5 million
- 220 kV and 380 kV: approx. €3 million
Once the connection is ready
You pay TenneT each month:
- 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.
If you wish to stop using your connection
TenneT will charge:
- 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.
