In the ongoing implementation of the flow based capacity calculation methodology in CCR Nordic, focus is now shifting to the upcoming period of parallel runs, where market participants and TSOs in parallel will be able to observe the similarities and differences between the current market coupling results and the market coupling results, where flow based parameters are used.
NEMOs have previously indicated a need to apply a so called “grace period” between date of actual operation (the trading day) and publication of results from the flow based simulation facility of up to 14 days. Market participants however, have expressed their need for swift feedback of the simulation results to make the best use and facilitate necessary learning from the parallel runs. In this letter to NEMOs and TSOs, NordREG is urging all parties involved to reduce the “grace period” to an absolute minimum.
