LTFBA - External Parallel Run
Published:
We would like to inform you that on the 24th of November 2025, the External Parallel Run for Core long-term flow-based(LTFB) implementation will start.
The external parallel run plays a key role in ensuring a smooth and reliable transition to the LTFB allocation and Go-Live readiness.
JAO, as the SAP Operator, and Market Participants will be involved in the testing in the following manner:
- The results of running the allocation algorithm based on 2025 historical bids will be published on the following page of JAO's website: https://www.jao.eu/LTFBA-external-parallel-run
- JAO will publish on its Publication Tool results of coordinated capacity calculation runs : https://parallelrun-publicationtool.jao.eu/coreLtfba/
Remarks:
- For yearly flow based calculation, the LT CC (MinMax) approach, currently under approval, is used for yearly flow-based calculation. However this is not including final evaluation and outage plannings.
- For monthly domains, zero (0) values for returns will be considered
- For Polish border created bids are added and Technical Profile PL/CZ/DE is no longer used
- To account for split auctions on Belgian-French and German-French borders, which will no longer be possible with long term flow-based, bids from the 2nd Y-auction for 2025 were multiplied with a factor (Total Y1+Y2 auction volume/Y1 auction volume).
