Published: 28/03/2019 | 09:43

Dear Market Participants,

Amprion would like to inform about the results of a performed SPAIC analysis and an update of the methodology of the Generation Shift Key of Amprion and adaption of German Sharing Keys for the CWE Flowbased Market Coupling in DA.
SPAIC stands for Standard Procedure for Assessing the Impact of Changes and consists of a comparison of the CWE flow-based domains and market results for 12 typical “reference” days, commonly predefined by CWE TSOs, in order to estimate the impact of a change in grid topology or FlowBased parameters in the CWE Region.
The new Amprion GSK and the update of the German Sharing Keys will be active from Business Day 18/04/2019 onwards.
The enclosed documents provide the results of the performed SPAIC analysis for the reference period of 2017 updated with the changes made for the DE/LU – AT Bidding zone split. A more detailed description of the GSK changes can be found attached.

Best regards

Amprion
