Why your views matter

CACM Guideline Art 20(8) states: “To enable market participants to adapt to any change in the capacity calculation approach, the TSOs concerned shall test the new approach alongside the existing approach and involve market participants for at least six months before implementing a proposal for changing their capacity calculation approach”. In line with the regulation, the CCR Nordic TSOs’ propose the following for the 6 months’ testing period of the Intraday Flow-Based Capacity Calculation Methodology: (i) The 6-months testing period is linked to the introduction of FB parameters in the IDA allocation (FB IDAs are currently planned in the course of 2027), (ii) The 6-months testing period is to demonstrate that FB domains can be calculated, and to show that the daily process works, (iia) The FB capacities will be published, (iib) No market simulations will be performed. The Nordic TSOs seek for input from the stakeholders: do you have any other suggestions for, or do you have any other needs to be met by, the 6-months testing period for the ID FB Capacity Calculation? If so, please do provide arguments why this is important to be considered.
