               CEZ Submits Follow-Up Bid for Kozienice Power Plant


CEZ continues in the privatization tender by submitting a follow-up bid for
Polish black-coal fired power plant Kozienice. Its first bid for the purchase of
at least 10% share submitted in the end of April this year brought CEZ among six
short-listed bidders.

Based on the bids submitted, the Polish Government will decide on the following
steps to be taken in the privatization process of Kozienice power plant.

"We have succeeded in acquisitions in the South-East Europe, where we own
distribution companies in Bulgaria and Romania. On attaining our vision to
become the leader of the power market in the Central and South-East Europe, we
perceive Poland as the strategic market in the Central Europe. With Poland being
a direct neighbor, both energy sectors are familiar with each other, which is
very important for potential future partnership," CEZ Chairman of Board and CEO,
Martin Roman, said.

Kozienice is one of the largest coal-fired power plants in Europe. It is a
refurbished power plant with installed output of 2 880 MW.

As part of its expansion, CEZ energy company successfully took over three
distribution companies in Bulgaria and in the beginning of April, it signed an
Agreement on Privatization of Oltenia Distribution Company in Romania. As a
result of these acquisitions, CEZ nearly doubled the number of its off-takers in
aggregate amounting to 6.6 million and according to this criterion, it finds
itself on the eighth position among European energy companies.
