The story

Elia was created as a result of the unbundling of the electricity market. On 28 June 2001, Elia became an independent public company by merging the Company for the Coordination of the Generation and Transmission of Electrical Energy (CPTE) with the Electrabel entity managing the 30-380 kV grid. On 17 September 2002, it was appointed as the federal transmission system operator in accordance with the Electricity Act of 29 April 1999. On 20 June 2005, Elia was listed on the Euronext Brussels and since 2012 has been part of the BEL20 index. On 8 July 2005, Elia set up the spot market power exchange Belpex, which has since been integrated into Paris-based EPEX SPOT.

On 12 March 2010, Elia and Industry Funds Management reached to an agreement with Vattenfall on the acquisition of the Vattenfall-owned German transmission system operator 50Hertz Transmission GmbH, one of the four German transmission system operators. The transaction was approved by the European Commission on 10 May 2010.
