The European interconnected grid allows exchanges of electricity between different countries.
Elia has introduced interconnection capacity allocation mechanisms for transnational energy exchanges. These mechanisms satisfy market demand in a transparent and non-discriminatory manner.
Elia reports the nominated capacity on Belgian borders on a daily basis and for each hour. There are several categories of nominated capacity: long-term (yearly and monthly), day-ahead (D-1) and intraday.
Electricity moves freely around the interconnected grid, taking no account of borders between countries. The physical exchanges are the real-time exchanges of energy observed at borders. The physical flows on the Belgian grid indicate how heavily each line is loaded in relation to the maximum possible loading of the line.

Deactivating grid components may result in modifications to the grid and/or lower capacity at our borders.
Transmission lines, transformers and other key grid components must be maintained regularly to keep the high-voltage grid running smoothly and minimise unscheduled interruptions on the grid.
Maintenance work may affect interconnection capacities or customers using the local grid.
