„Balancing market“ pillars
Cooperation between TSO while using standard products
Common market with balancing reserves
Common market with balancing energy
Real-time cooperation
Imbalance settlement harmonization
• Balancing
reserves standard products
• Methodologies for cross-border capacity acquisition
• Balancing energy
standard products
• Gate closure time for bid submission close to real-time
• Balancing energy
settlement harmonization
• Imbalance
settlement period 30min and less
• Imbalance calculation harmonization
• Imbalance settlement price harmonization
Exchange of reserves
Sharing of reserves
Common merit order list
Imbalance netting

Coordinated Balancing Area
Coordinated Balancing Area (CoBA): geographical area with harmonized
rules for national balancing reserve and energy market and with rules for
market participants
• Common framework for „Terms and conditions related to Balancing“ (= Grid code + ordinance on electricity market rules)
• Each TSO must be in a CoBA with at least one other TSO from a different member state
• Exchange of a standard product and imbalance netting • Central operation of the „Balancing market“

„EU wide Balancing market“
Almost zero experience
Regional cooperation will be crucial for further developement
Will be other „core“ business for transmission system operators
