Balancing markets

Information based on provisional data as of January 2024

The balancing markets (secondary control, tertiary regulation, replacement reserve, and secondary control reserve avoided via the European platform for International Grid Control Cooperation, IGCC) have had total energy needs of 13,530 GWh. Of this total, 49.8 % corresponded to upward energy management and the remaining 50.2 % to downward energy management.

The largest energy needs were covered by secondary and tertiary regulation. It is worth highlighting the significant share of renewable generation in these services.

In 2023, almost all the activation of the tertiary control service was scheduled (99.3 %), which is why aggregate data for both activations are included in this report for all the data corresponding to tertiary control allocations.
