Call for Interest - Scenarios ETAG

Closed 5 Jun 2023

Opened 5 May 2023


Call for interest of participating stakeholders to join the Scenarios External Technical Advisory Group (Scenarios ETAG) by 5 June 2023 

Since 2018, ENTSO-E and ENTSOG have been developing joint scenarios for their respective Ten-Year Network Development Plans (TYNDP). Due to the importance of the TYNDP scenarios for European infrastructure planning, the scenarios benefit from thorough and inclusive stakeholder engagement.

Article 12(3) of Regulation 2022/869 (TEN-E Regulation) of 30 May 2022 specifies that ENTSO-E and ENTSOG ‘shall invite the organisations representing all relevant stakeholders [...] to participate in the scenarios development process, in particular on key elements such as assumptions and how they are reflected in the scenarios data. ACER’s Framework Guidelines on the joint TYNDP scenarios states that ENTSO-E and ENTSOG should create a stakeholder reference group. It adds that a call for interest should target stakeholders listed in Article 12(3) of the TEN-E Regulation and other relevant organisations and independent experts. With this call for interest, and the proposed draft Terms of Reference (ToRs), ENTSOG and ENTSO-E initiate the creation of the independent Scenarios ETAG.

Objectives of the Scenarios ETAG

With the aim of strengthening and complementing existing stakeholder engagement methods, the Scenarios ETAG will have the following objectives:

  1. Identifying and giving feedback to ENTSO-E and ENTSOG on which parts of the scenario-building process benefit from further discussion within Scenarios ETAG;
  2. Providing advice at key stages of the scenario-building process on the inputs, assumptions, and methodologies;
  3. Providing feedback on the scenario-building process at the end of each cycle.

For more information please consult the draft Terms of Reference developed by ENTSO-E and ENTSOG.
