Our grid is part of a larger, European interconnected system. A number of mechanisms control exchanges of electricity between countries.
Each Access Responsible Party (ARP) is able to exchange energy with neighbouring countries, with a view to maintaining the balance between generation and consumption at the injection point falling under its responsibility.
A number of allocation mechanisms are used to allocate the desired volume of energy to ARPs on an annual, monthly, daily or intraday basis. For further information about the general operation of these cross-border mechanisms, see General information.
The volume of these exchanges depends on the import and export capacity available on the lines providing interconnections with France and the Netherlands. You can find out more on the Transmission capacity at the borders page.
For more specific information about how the data relating to these exchanges (Total Transfer Capacity, Transmission Reliability Margin, etc.) are calculated, see the Calculation methods page.
