E.ON enters Romanian electricity market

The privatization agreement which was concluded between E.ON and the Romanian government in Bucharest today paves the way for E.ON’s acquisition of a majority stake in Romanian regional utility Electrica Moldova S.A. Under the agreement, E.ON Energie AG will purchase a 24.62% shareholding and immediately boost this to 51% by raising the company’s capital stock.

With its portfolio of 1.3 million customers and electricity sales of around four billion kilowatt hours, Electrica Moldova, which is based in the north-eastern part of Romania, has an 11% share of the country’s wholesale market. In 2003, Electrica Moldova recorded sales of 203 million euros.

The acquisition is a further milestone in the implementation of the E.ON Group’s strategy of growing its Central and Eastern European business. In October 2004, E.ON Energie purchased a stake in the Bulgarian utilities Gorna Oryahovitza and Varna. In the same month, E.ON Ruhrgas acquired a shareholding Romanian gas utility Distrigaz Nord.

Wulf H. Bernotat, Chairman of E.ON AG’s Board of Management: “Purchasing a controlling interest in Electrica Moldova further consolidates our market position in Central and Eastern Europe. It also gives us unrivalled scope for leveraging cross-border synergies in the region.”
