Topic

Elia organizes a public consultation from Friday 28 October 2022 until Monday 28 November 2022, on the methodology, the basis data and scenarios that will be used for the study regarding the adequacy and flexibility needs of the Belgian power system, which must be carried out every 2 years.

Context

The basic assumptions and scenarios, as well as the methodology used for this analysis, shall be determined by the system operator in collaboration with the Directorate General for Energy and the Federal Planning Bureau and in concertation with the regulator."

The documents submitted to this public consultation are:

  • A general document detailing the context, generalities, and assumptions of the central scenario;

  • An Excel file containing all assumptions proposed as part of the central scenario of the study;
  • 9 methodological appendixes:
    • Unit Commitment and Economic Dispatch;
    • Adequacy study;
    • Adequacy patch;
    • Climate years;
    • Cross-border exchange capacities;
    • Hourly electricity consumption;
    • Economic viability assessment;
    • Methodology for the assessment on short-term flexibility;
    • Assumptions for the assessment of short-term flexibility; 
  • 4 external studies on different aspects of the study:
    • The AFRY study on: "Update of the peer review of “Cost of capacity for calibration of Belgian CRM";
    • The study from N-SIDE on "Study on the outage parameters of generation units and DC links";

    • The study from Professor K. Boudt on "Analysis of hurdle rates for Belgian electricity capacity adequacy and flexibility analysis over the period 2024-2034".

This consultation aims at receiving any comment from market participants on these data and the methodology as well as any suggestion on possible sensitivities on the central scenario but also feedback regarding the scenario parameters for the "Low Carbon Tender" 2024-25.
