Unscheduled extension of XBID system outage
On Saturday, 6 September 2025, the intraday continuous market experienced unscheduled unavailability of the central XBID system used for cross-border intraday continuous trading.
The XBID system was originally scheduled for maintenance between 07:00 and 09:30. However, due to unforeseen technical issues on the service provider’s side, the maintenance had to be extended, leading to unscheduled downtime from 09:30 until 17:50.
To ensure trading continuity, local matching in Slovak market area was activated between 14:30 and 17:50, enabling market participants to cover their needs during the unavailability of the single cross-border intraday market.
From 17:50 onwards, the system was restored, and trading continued in the standard cross-border mode. The system is currently fully operational. In cooperation with the service provider, a thorough investigation is underway to identify the root cause of the outage and to ensure that such a situation does not reoccur in the future.
The SIDC (Single Intraday Coupling) parties remain committed to maintaining the highest standards of operational resilience and transparency towards the market and sincerely apologize for this unintended disruption to trading.
