Elia System Operator SA (short name: Elia; EuronextELI) is an electric power transmission system operator of Belgium.


Elia was created as a result of the legal unbundling in the electricity market. On 28 June 2001, Elia became the independent limited liability company. It was appointed as the federal transmission system operator on 17 September 2002. On 20 June 2005, Elia was listed on Euronext Brussels. On 8 July 2005, Elia set up the power exchange Belpex, which is in the process of being integrated into APX-ENDEX.[1]

On March 12, 2010, Elia and Vattenfall reached to an agreement on acquisition of the Vattenfall-owned German transmission system operator 50Hertz Transmission GmbH by Elia. The deal was approved by the European Commission on 10 May 2010.[2]


Transmission system operators in Germany along with their owners: TenneT, Elia, RWE and EnBW

Elia owns all of Belgium's 150 to 380 kV grid infrastructure and almost 94% of its 30 to 70 kV grid infrastructure. In addition to the Belgium market, Elia operates also in Germany through its subsidiary 50Hertz Transmission GmbH.[2] The company studies interconnection projects with the United Kingdom (Nemo project), Luxembourg and Germany.[3]

Elia has a 60% stake in the power exchange Belpex. As activities of Belpex will be integrated with the energy exchange APX-ENDEX, Elia will receive a 20% stake in APX-ENDEX in exchange of its stake in Belpex.[1][4]

Elia is a contributor to the inter-regional electricity trading joint venture the European Market Coupling Company.[5]


52.1% of Elia's shares is freely floated on Euronext, 45.37% is owned by Publi-T SCRL, a cooperative company representing Belgian municipalities and intermunicipal companies, and 2.53% by Publipart, a holding company of SPE.
