Explanation of system balance

Volume data are expressed in MW and are based on observations regarding the five-minute average of each Programme Time Unit (PTU).

• The net exchange concerns the exchange programme between the Netherlands and other countries within the UCTE system (Belgium and Germany; + import, - export).
• The exchange difference concerns the difference between the net measured exchange with other countries and the net exchange programme; the inadvertent exchange (+ surplus, - deficit).
• The balance of TenneT’s contribution concerns the net capacity requested by TenneT on the basis of bids for the purpose of maintaining the balance (+ upward adjustment, - downward adjustment). Any emergency capacity used will not be included in the balance of TenneT’s contribution.
  

The situational parameters relate to one PTU:

• Regulating state (-1, 0, 1, 2): based on the SysteemCode [System Code], TenneT explicitly determines the regulating state.
• Emergency capacity indicator (0, 1): if emergency capacity is activated, TenneT will immediately set this operational parameter to 1. Depending on the dispatch time of the activated emergency capacity, a price for emergency capacity will be established in this PTU which will act as a determining factor for the imbalance price.
• The regulating state and the emergency capacity indicator in the overview of settlement prices will play a leading role in the settlement.
