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.

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.
