Transparency obligationsOur transparency obligations at Belgian and European level are governed by an ever-changing legal and regulatory framework.

EIC CodesAn EIC code is needed to exchange data on the energy market. You can apply for your code here or consult the list of codes that have already been allocated.

Load data

Careful load monitoring is required to ensure continuity of supply, taking into account production and network constraints.

Power generation data

As production is becoming more and more diversified, a good knowledge of it is necessary to ensure an efficient and qualitative supply of energy.

Transmission data

Efficient use of our grid and our interconnection capacity, in accordance with the applicable allocation mechanisms, is vital for ensuring security of supply.

Adequacy data

To ensure the adequacy of the Belgian system, Elia cooperates on the implementation and operation of the adequacy mechanisms put in place by the Belgian government.

Balancing data

When an imbalance between generation and consumption occurs on its grid, Elia can use a wide range of measures to restore the balance.

Congestion Management data

When grid components are overloaded or at risk of becoming overloaded in the event of an incident, Elia can activate congestion management measures on its transmission grid to bring the situation back into the applicable safety standards.
