-    Scheduling (ESS) application from 17:30 CET until approximately 19:00 CET on 15.09.2026.
During this period, day-ahead and intraday schedule nominations at all Slovenian borders will not be possible. The maintenance works will not affect already confirmed nominations for deliveries within the above-mentioned maintenance window. Furthermore, capacity allocation via the common SIDC (XBID) platform will not be possible at any Slovenian border.

-    Platform for Balancing System (BS) from 18:00 CET until approximately 20:00 CET on 15.09.2026.
