Important information for suppliers and customers with Elia System Operator. No change for Elia Asset or Elia Engineering

General remarks

  • Elia has decided to undertake an internal reorganisation with a view to separating its regulated activities in Belgium, i.e. its ownership and operation of the high and very-high-voltage electricity transmission system in that country (including its participation in Nemo Link), from its regulated and non-regulated activities outside Belgium.
  • As part of the reorganisation of the Elia Group, Elia System Operator (ESO) will transfer all its Belgian regulated activities to its subsidiary Elia Transmission Belgium (ETB), a public limited company under Belgian law having its registered office at Boulevard de l'Empereur 20, 1000 Brussels, Belgium and listed in the Register of Legal Entities (Brussels) under number 0731.852.231. Elia Transmission Belgium will be designated as Belgian TSO at federal and regional levels.
  • ESO will then become a listed holding company with stakes in various subsidiaries: not only Elia Transmission Belgium but also other subsidiaries such as Eurogrid International (including the various arms of the German TSO 50Hertz) and Elia Grid International (EGI).
  • Elia is making every effort to complete this reorganisation, including obtaining the actual designations of Elia Transmission Belgium as TSO at the federal and regional levels, by 1 January 2020. However, if the formal decisions designating Elia Transmission Belgium have not been finalised by then, a temporary contractual framework may be put in place between ESO and Elia Transmission Belgium to enable the latter to operate the national transmission system and the regional (local) transmission systems as a subcontractor from 1 January 2020, pending this designation.
