CAPACITY CALCULATION

DEVELOPMENT OF METHODOLOGIES RELATED TO DAY-AHEAD AND INTRADAY CAPACITY CALCULATION

 

See disclaimer at the end of the page.

Definition of capacity calculation regions (CCRs)

Pursuant to Article 15 of the CACM Regulation, all TSOs need to develop a proposal for capacity calculation regions and submit it to all regulatory authorities for approval and to the Agency for information.

Action 1: By November 2015, all TSOs submitted to all regulatory authorities and the Agency the proposal for capacity calculation regions.

Action 2: In May 2016, all regulatory authorities informed the Agency that they were not able to reach an agreement on the proposal for capacity calculation regions. In accordance with Article 9(11) of the CACM Regulation, the Agency thereby became competent to adopt a decision on the proposal for capacity calculation regions.

Action 3: In November 2016, the Agency adopted a decision on the proposal for capacity calculation regions.

Action 4: In August 2017, all TSOs submitted to all regulatory authorities and the Agency the proposal for the first amendment of capacity calculation regions.

Action 5: By February 2018, all regulatory authorities approved the proposal for the first of capacity calculation regions pursuant to Action 4.
Action 6: In April 2018, all TSOs submitted to all regulatory authorities and the Agency the proposal for the second amendment of capacity calculation regions.

The proposal for the definition and amendments of capacity calculation regions have been implemented on the day of the Agency's decision or the day of the decision of the last concerned regulatory authority.

Common grid model (CGM)

Pursuant to Article 17 of the CACM Regulation, all TSOs need to develop a proposal for a common grid model methodology and submit it to all regulatory authorities for approval and to the Agency for information.

Action 1: By July 2016, all TSOs submitted to all regulatory authorities and the Agency the proposal for a common grid model methodology.

Action 2: In January 2017, all regulatory authorities requested from all TSOs to amend the proposal for a common grid model methodology.

Action 3: By April 2017, all TSOs submitted to all regulatory authorities and the Agency the amended proposal for a common grid model methodology.

Action 4: By July 2017, all regulatory authorities approved the proposal for the common grid model methodology.

The common grid model methodology is expected to be implemented in several steps within 13 months after the regulatory approval. You can find more details on these steps within the approved methodology.

Generation and load data provision (GLDP)

Pursuant to Article 16 of the CACM Regulation, all TSOs need to develop a proposal for generation and load data provision methodology and submit it to all regulatory authorities for approval and to the Agency for information.

Action 1: By August 2016, all TSOs submitted to all regulatory authorities and the Agency the proposal for generation and load data provision methodology.

Action 2: By July 2017, all regulatory authorities approved the proposal for the generation and load data provision methodology.

Capacity calculation methodology (CCM)

Pursuant to Article 20 of the CACM Regulation, all TSOs in each capacity calculation region (CCR) need to develop a proposal for a common coordinated capacity calculation methodology within the respective CCR and submit it to all regulatory authorities of the respective CCR for approval and to the Agency for information.

Action 1: By September 2017, the TSOs from CCRs CORE and NORDIC submitted to the concerned regulatory authorities and the Agency the proposals for the common coordinated capacity calculation methodology using the flow-based approach.

Action 2: By January 2018, the TSOs from CCRs BALTIC, CHANNEL, GR-IT, HANSA, IU, SEE, SWE submitted to the concerned regulatory authorities and the Agency the proposals for the common coordinated capacity calculation methodology using the coordinated net transmission capacity approach.

Action 3: In March 2018, the relevant regulatory authorities requested from their respective TSOs to amend the proposal for common coordinated capacity calculation methodology for the CCRs BALTIC, CHANNEL, CORE, GR-IT, IU, NORDIC and SWE.
