Coordinated capacity calculation

The Nordic RSC must calculate cross-border transmission capacities and maximise the transmission capacity offered to the market.

In the beginning of 2018 the Steering Group decided on a stepwise approach for the CCC service:

  • Step 1a: Nordic RSC office, take responsibility for sending day-ahead capacities to NordPool using NOIS (Went live on the 5th of September 2018). Which includes:
    • Define routines and fallback routines, together with the Nordic TSOs, NordPool and NOG
    • New RSC Core Room to support routines and fallback routines
  • Step 1c: Nordic RSC office coordinate, deliver and verify DA capacities and verify results for DA flow, in Nordic Area with more NEMOs (Went live on the 3rd of June 2020).
  • Step 2 NorCap Project: RSC calculates Flow Based (FB) capacities. TSOs approve. RSCs send to NEMOs.
    • Process to procure tool for flow based calculation is ongoing
    • Expected Go-Live by end 2020.
  • Step 3: RSC calculates FB capacities taking into account dynamic security analysis.
