The change will be implemented in October 2020. Currently, the time change is handled by using either 0 MWh values for the non-existent interval or using aggregate values of doubled intervals. This change is due to a planned implementation of a new IT system at Borzen. According to paragraph 4 of Article 90 of the aforementioned Rules, this change will also affect the setting of the SIPXobri price index. Imbalance settlement reports will be updated accordingly.
