Two sets of rules for sharing the costs incurred by TSOs

​​​The European Union Agency for the Cooperation of Energy Regulators (ACER) publishes a Decision on the principles for sharing the costs of ensuring firmness and remuneration of long-term transmission rights (LTTRs).

The Decis​ion determines two sets of rules for sharing the costs incurred by Transmission System Operators (TSOs):

  • The first principle regulates the costs incurred in case of long-term cross-zonal capacity's curtailment before the day-ahead firmness deadline. This can happen to ensure the operation remains within the operational security limits.

  • The second principle manages the costs incurred to remunerate the long-term transmission rights after the re-allocation of cross-zonal capacity to the single day-ahead coupling.

The principles will be applied together with the regional capacity calculation methodologies.
