Poland — 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

639,921,067 € for 2,109,741 MWh that stayed in the country works out at 303.32 € per megawatt-hour, in a month that averaged 115.19.

Energy that stayed, at the month's average price 243,021,320 38.0%
What came in arrived above that average 203,825,003 31.9%
What went out left below it 193,074,744 30.2%

The first line is energy the country needed and got. The other two — 396,899,747 € 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.

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.
