Capacity Allocation and Congestion Management

​​​​​​​​​​​​​​​​​​​​​​This section lists the different information linked to the implementation of the EU regulation on the implementation of the capacity allocation and congestion management guideline - the "CACM regulation".


21/04/2017 - All TSOs’ proposal for a Congestion Income Distribution Methodology

Following NRAs amendments request, the common Transmission System Operators (TSOs) amended proposal regarding a Methodology for the Congestion Income Distribution (CID), in accordance with article 73 of the Commission Regulation EU (No) 2015/1222 establishing a guideline on capacity allocation and congestion management (the CACM Regulation) has been submitted to the NRAs and the Agency.

10/03/2017 – Publication of GLDPM-related data pursuant to Article 16(6) of Regulation 2015/1222

Article 16(6) of Regulation 2015/1222 sets out the obligation for ENTSO-E to publish “[n]o later than two months after the approval of the generation and load data provision methodology by all regulatory authorities” the following information:

“(a) a list of the entities required to provide information to the TSOs [under the GLDPM];

(b) a list of the information referred to in paragraph 3 to be provided [paragraph 3 stipulates that the GLDPM “shall specify the information to be provided by generation units and loads to TSOs” and it sets out minimum requirements in this respect];

(c) deadlines for providing information.”

In order to ensure that this obligation is respected, Article 18(2) of the GLDPM requires each TSO, “[b]y one month after the approval of the [GLDPM]”, to complete the following tasks:

“(a) inform the entities required to provide data about the information they are required to provide as well as the deadlines for providing the information;

(b) forward the information set out in (a) to ENTSO-E;

(c) prepare draft implementation rules on the practicalities of data provision specifying, for example, data formats and technical requirements with respect to the IT implementation of the data provision process in accordance with the procedures applicable under national law. Each TSO shall ensure that these implementation rules make use of existing infrastructure and data delivery processes to the extent possible and it shall allow sufficient time for implementation; where appropriate TSOs shall also provide clarification on definitions and other guidance as may be required.”

In keeping with the GLDPM’s guiding principle that “[e]ach TSO shall have the right but not the obligation to obtain (…) data”, set out in Article 3(1) of the GLDPM, for the time being only a subset of TSOs decided to request data under the GLDPM. The following TSOs provided their GLDPM data requirements to ENTSO-E by the deadline of 11 February 2017:

  • 50HzT (DE)
  • Amprion (DE)
  • Energinet.dk (DK)
  • Svenska Kraftnät (SE)
  • TenneT TSO B.V. (NL)
  • TenneT TSO GmbH (DE)
  • TransnetBW (DE)

As required by Article 16(6) of Regulation 2015/1222, ENTSO-E is publishing the information provided by TSOs:

In addition, APG (AT), Elering (EE), Elia (BE), Fingrid (FI), NGET (GB), and RTE (FR) explicitly indicated that they would not seek to obtain data under the GLDPM for the time being.

The ENTSO-E Secretariat did not verify in detail the consistency of the data files submitted by TSOs with the GLDPM. Most of these data files were prepared in TSOs’ respective national languages or at least contained national language technical terms. ENTSO-E also would not have been able to assess with reasonable effort whether the assignment of different entities to different categories of data providers is accurate.

However, the following checks were completed and the data submissions were found to be satisfactory in this respect:

  • the deadline set out in Article 18(2) of the GLDPM was respected;
  • the files describe the information requested;
  • the files contain or refer to deadlines for providing the information.

When acknowledging receipt, ENTSO-E also reminded TSOs of their other obligations under Article 18(2) of the GLDPM.

The ENTSO-E '2nd Report on the progress and potential problems with the implementation of the Single Day-Ahead and Intraday Coupling', in accordance with Article 82(2) of the Commission Regulation EU (No) 2015/1222 establishing a guideline on capacity allocation and congestion management (the CACM Regulation) has been submitted to ACER.

12/01/2017 - Generation and Load Data Provision Methodology approved; Common Grid Model Methodology subject to amendments

​​​In the summer of 2016, all TSOs submitted the Common Grid Model Methodology (CGMM) as well as the Generation and Load Data Provision Methodology (GLDPM) to all regulatory authorities (NRAs) for approval under Regulation 2015/1222 (“CACM Guideline”). Stakeholders had earlier been consulted on these documents and the public consultation included a workshop held at ENTSO-E Secretariat on 18 February 2016.

We are pleased to announce that the NRAs have now made a decision on both of the methodologies. The Generation and Load Data Provision Methodology (GLDPM) was approved without modifications. As for the CGMM, NRAs require three modifications to be made.

View the Generation and Load Data Provision Methodology

In the following we want to outline the changes requested by NRAs and we also want to describe the next steps in the process of updating the methodologies with the requirements set out in Regulation 2016/1719 (“FCA Guideline”) which has entered into force in October 2016.

GLDPM-v1 submitted under Regulation 2015/1222

NRAs have unanimously agreed amongst each other that the GLDPM shall be approved without the NRAs requiring an amendment. The decision is now made legally valid and binding through national-level decisions which TSOs either have already received or expect to receive from their respective NRA very shortly.

CGMM-v1 submitted under Regulation 2015/1222

NRAs have unanimously agreed amongst each other that they will require the CGMM to be amended as a precondition for approving it. This decision is also made legally valid and binding through national-level amendment requests which TSOs either have already received or expect to receive from their respective NRA very shortly. Note that the amendment request is to be understood as a conditional approval decision: if the amendments requested by the NRAs are implemented by the TSOs, the understanding is that the NRAs shall then approve the (amended) CGMM without requiring additional modifications.

Our understanding is that the amendment request will set out three modifications required by all NRAs:

  • The CGM process deadlines in Article 23 of the CGMM shall be removed for the time being. The reason for this is the perception on the part of the NRAs that the CGM process deadlines constrain the Intraday Cross-Zonal Gate Opening Time (IDCZGOT).
  • Two additional change requests relate to the delegation of tasks to ENTSO-E and the inclusion of agreed measures in the CGM process. On all three issues we expect TSOs to be able to agree on an amended version of the CGMM shortly and to submit it to NRAs within the deadline set by the CACM Regulation.

Preparation of CGMM-v2 and GLDPM-v2 required under Regulation 2016/1719

Regulation 2016/1719 (“FCA Guideline”) obliges TSOs to update the methodologies with additional requirements related notably to capacity calculation for long-term timeframes. The revision of the currrent versions of the methodologies is under way. We expect to make the revised versions available to stakeholders on 06 March. A workshop with stakeholders is planned for Monday, 27 March 2017, and the public consulation will end on 06 April 2017. We will provide additional information on the workshop as well as the public consultation nearer the time.
