According to reports, the Spanish utility Iberdrola is in discussions to sell its shares in Empresa Electrica de Guatemala SA (EEGSA) to Colombian company Eléctrica de Medellín (EDM).
Iberdrola's decision would be related to the reduction of tariffs in over 50% approved by the National Energy Commission (CNEE) in June of 2008. In November 2009, Iberdrola sued Guatemala with an international arbitration proceeding for $ 672 million, questioning the reduction.
