Core TSOs' proposal for the 3rd amendment of the Intraday Capacity Calculation Methodology – Related to ATC

Overview

This consultation concerns the Core CCR TSOs’ proposal for the third amendment of the Intraday Capacity Calculation Methodology of the Core Capacity Calculation Region (‘Core ID CCM’) in accordance with article 20ff. of the Commission Regulation (EU) 2015/1222 of 24th July 2015 establishing a guideline on Capacity Allocation and Congestion Management (CACM).

The Intraday process is subject to constrained timings. Core TSOs identified the need to validate the outcome of the IDCC process during an Available Transferable Capacity (ATC) based validation step in addition to the CNEC (= Critical Network Element with Contingency) based validation. The validation step could identify ATC which are too high and jeopardize grid security. These calculated ATCs can then be reduced by the validating TSO during the ATC validation step, as long as an ATC extraction will be performed from the Flow-Based domains resulting from the final computation.

Why your views matter

We are seeking input and feedback from Core stakeholders, market participants, NRAs and NEMOs on our proposal for third amendment of the Intraday Capacity Calculation Methodology of the Core Capacity Calculation Region.

TSOs of the Core CCR (50HERTZ, AMPRION, APG, CREOS, ČEPS, ELES, ELIA, HOPS, MAVIR, PSE, RTE, SEPS, TENNET GMBH, TENNET BV, TRANSELECTRICA, TRANSNETBW) are initiating this open online consultation on a draft of the third amendment Proposal in accordance with Article 12 of the Commission Regulation (EU) No 2015/1222 of 24 July 2015 establishing a Guideline on Capacity Allocation and Congestion Management. 

For information purposes, an Explanatory Note describing in more detail the proposed implementation ATC validation and the proposed changes to the Intraday Capacity Calculation Methodology, is added as well.
