Outage Planning Coordination

The Outage Planning Coordination (OPC) process ensures coordination of planned grid outages for the high-voltage grid maintenance to minimize their impact on security of supply and the electricity market.

The OPC task facilitates regional coordination by evaluating how planned outages in one area may affect neighbouring systems. TSOs exchange information, align their schedules, and RCCs identify cross-border Tie-Line Inconsistencies (TLIs) to ensure consistency and data quality. All planned outages of key grid elements are registered in a common database to support coordinated planning.

OPC is carried out on both regional and pan-European levels, with RCCs leading the coordination. Regional OPC ensures outage coordination of grid elements and generating units on a regional level. Pan-European OPC ensures consistency of outage planning across all regions. The main aim is to provide an assessment of Outage Planning Incompatibilities (OPI) in the Baltic region and provide proposals to the Baltic TSOs on how to mitigate and/or eliminate the indicated incompatibilities.
