Cross Border Balancing

The Transmission System Operators have two different mechanisms at their disposal to exchange energy for balancing purposes.


BALIT (Balancing Inter TSO) mechanism enables the TSOs to exchange tertiary reserve. National Grid, RTE, REE and REN, the participating TSOs can send offers to the balancing mechanisms of the neighbouring countries. These offers are activated according to economic precedence like any other offer on the balancing mechanism. Therefore they contribute to the optimization of balancing prices for the benefit of all stakeholders.

IGCC (International Grid Control Cooperation) initiative enables the netting in real-time of the imbalances of participating TSOs: 50Hertz, Amprion, APG, CEPS, Elia, Energinet.dk, RTE, Swissgrid, TenneT and TransnetBW. The purpose of this cooperation is to avoid counter activation of automatic Frequency Restoration Reserves (aFRR) when the need for aFFR can be compensated by an opposite need in a neighbouring Control Area (up to the capacity available at the border). The financial profits of this optimization for RTE will be integrated in the Adjustment Account (“compte ajustement-écarts”) and will therefore benefit to all French market participants.
