Overview of the implementation process in the Nordics
Day Ahead and Intraday Capacity Calculation Methodology
The implementation timeline for a flow-based method for capacity calculation is dependent on successful parallel runs and confirmation from the Nordic NRAs. The parallel operations have been divided into phases (parallel runs). Each phase has TSO-defined entry criteria, based on the guidance from NRAs.
The entry criteria for the EPR start have been set. Entry criteria for each phase is the same as the exit criteria for the previous phase. More information on the criteria for the External parallel run (pdf)
According to stipulated timeline, the external parallel operation must last for at least 12 months.
The NRA reporting consists of three month of data. Read the external parallel run Evaluation report submitted to the NRAs
NRA CONFIRMATION FOR CONTINUED FB IMPLEMENTATION
On 12 July, the Nordic NRAs confirmed the Nordic CCM External Parallel Run Evaluation Report and the continued implementation of flow-based capacity calculation in the Nordics. At the same time, the NRAs conclude that they expect additional actions for the upcoming 6 months of EPR to address remaining open issues beyond the established KPIs.

Please note that the parallel run will generate data that can used as a basis to facilitate the adaptation of planning tools and/or business processes of all stakeholders concerned.
