Brussels, 03/07/2009 (Agence Europe) - According to German media reports, the European Commission is preparing to fine French energy giant GDF Suez and Germany's E.ON AG for reaching an illegal agreement. The Commission may decide to fine the two gas suppliers up to 10% of their turnover on Wednesday 8 July 2009, according to reports in Germany's business paper Handelsblatt. The European Commission opened an investigation into the two companies in 2007, suspecting them of illegally agreeing on the supplies of gas through the Megal gas pipeline that the two companies run together. The European Commission accuses the two companies of pledging not to sell gas on the other company's national market. (C.D./transl.fl)
