Adequacy Working Group 

Market parties can discuss the development and evolution of the different mechanisms related to the adequacy topic within this working group

What does the Adequacy Working Group do?

Adequacy ensures that the total available and expected capacity, including imports, is sufficient to meet demand at all times. To guarantee Belgium’s security of supply in the long term the federal government’s energy strategy laid out a few years ago a number of new measures in order to face energy supply challenges. As the operator of Belgium’s high-voltage grid, Elia advises the federal government on guaranteeing the country’s security of supply. Moreover, Elia is responsible for a number of tasks assigned to Elia by law.

The working group deals with a variety of subjects, including:

  • the Strategic Reserve;
  • the Capacity Remuneration Mechanism ; and
  • the biannual 10 year Adequacy & Flexibility Study.


The Adequacy Working Group meets around eight times a year and reports directly to the plenary meeting.

Administrative duties for this working group are handled by:

  • Chairman: James Matthys-Donnadieu
  • Secretary: Martine Verelst
  • Documents
  • Public Consultations
