CEZ has thus entered into the privatization tender on a min. 10% share in this anthracite power plant. Based upon preliminary offers, the Polish government is to choose a selected group of bidders and will later decide also on the specific size of the privatized share. "The energy corporation CEZ has previously been successful in making acquisitions in southeast Europe, where we own distribution companies in Bulgaria and Romania already. Pursuing our goal to become the leader in the electricity market of the CEE region, we find that Poland is the strategic market in Central Europe for us. The immediate proximity with Poland means that both energy companies know each other well, which is key for a possible future partnership," says Martin Roman, Chairman of the Board and CEO of CEZ. Kozienice is the largest Polish thermal power plant and one of the largest power plants in Europe. It represents a highly modernized power plant that complies with EU criteria and features a net output of electric power of 2 845 MW. In the course of its expansion activities, CEZ has so far smoothly taken over three Bulgarian-based distributors and at the beginning of April signed an agreement on the privatization of the company Oltenia in Romania. By way of these acquisitions, CEZ almost doubled the number of its final customers to 6.6 million and thus soared to the eighth rank among Europe's energy companies in terms of this criterion.
