Czechia — physical cross-border flows, 2026

Every month of the year, every border, in energy and in money. Flows are measured; each megawatt-hour is valued at Czechia's own day-ahead price for the quarter-hour it actually crossed in.

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

778,806,694 € for 3,883,648 MWh that stayed in the country works out at 200.53 € per megawatt-hour, in a month that averaged 112.36.

  • Energy that stayed, at the month's average price −436,350,921 56.0%
  • What came in arrived above that average −150,747,399 19.4%
  • What went out left below it −191,708,374 24.6%

The first line is energy the country needed and got. The other two — 342,455,773 € 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.

Method

Not an invoice. Cross-border electricity is not sold country to country: the markets are coupled and the physical flow is the outcome of a shared auction. These figures value the measured flow at this zone's own day-ahead price, so both directions can be compared on the same scale.

Flows are measured, quarter-hour by quarter-hour; hourly borders are spread across the four quarters they cover, so every megawatt-hour meets the price that was actually in force. Energy entering the country is not the same as energy consumed here — some of it passes through.

A country between two others carries energy that is neither produced nor consumed there. Energy entering is not energy used.
