Belgium — physical cross-border flows, 2026

Month by month

All borders together, with consumption for scale.

Consumption is measured separately, as the hourly average power summed over the month — not by adding up readings, since sources publish at different rates. The last column puts imports next to it for scale; it is not a dependency figure, because part of what enters passes straight through to another neighbour.

Where the difference comes from

1,789,754,187 € for 16,507,291 MWh that stayed in the country works out at 108.42 € per megawatt-hour, in a month that averaged 102.77.

Energy that stayed, at the month's average price 1,696,390,978 94.8%
What came in arrived above that average 39,544,425 2.2%
What went out left below it 53,818,783 3.0%

The first line is energy the country needed and got. The other two — 93,363,208 € together — come not from how much moved but from when: cheap hours to sell in, expensive hours to buy in. That is the price of a timing mismatch, not a loss.

Gross volumes differ by design: the official indicators include transits, and a transit is counted once entering and once leaving, while a physical border sees it only once. Net figures converge, because transits cancel out — which is why the comparison is made on the net.

The percentage relates the difference to the month's commercial net. In a month with a small net, the same difference in MWh yields a larger percentage — which is why the difference is always shown in MWh as well.

ANRE publishes these exchanges as a physical balance in GWh. It publishes no import or export value and no average price per direction, so no money comparison is possible.

Physical cross-border flows and commercial electricity trades measure different phenomena. ANRE data is shown as an independent official benchmark and should not be interpreted as an exact reconciliation.
