Amendment to the Methodology for regional sizing of reserve capacity

Overview

Article 3(2) of the Methodology for regional sizing of reserve capacity (as introduced by ACER Decision No 12/2023*) requires that in order to apply the Methodology in a SOR, the relevant TSOs, supported by relevant RCC(s), shall determine in a coordinated manner the parameters referred to in the RCC Sizing Methodology.

Following the TSOs and RCCs coordination, ENTSO-E developed an amendment to this Methodology in accordance with Article 27 of Regulation (EU) 2019/943, proposing the parameters’ values included in an Annex. This amended proposal includes per SOR the definition of the levels X and Y referred to in Article 4 of the RCC Sizing Methodology and the time period considered for the historical records related to in Article 4(4)(a) of the same Methodology. In addition, the proposal includes an amendment to Article 7 (Implementation timeline) of the RCC Sizing Methodology, correlating the start of the RCC’s implementation of the short-term assessment of availability of sharing amounts to the notification by TSOs of their intention to establish and apply sharing agreements.

The proposal has been prepared by SORs and ENTSO-E, supported by the relevant RCC(s).
