    CEZ files Bid for Pljevlja Power Plant and for Stake in Nearby Coal Mine

The energy corporation, CEZ, has filed its bid today for the acquisition of the
Montenegro-based thermo-electric power plant, Pljevlja, and for a 31.1% share in
the mining company "Rudnik uglja", A.D., which supplies the power plant with
lignite fuel.

"The power plant, Pljevlja, and the neighboring mining company are at the focus
of our interest in Southeastern Europe. CEZ Group is already conducting business
in the area of distributing electricity in Bulgaria and Romania," says Martin
Roman, chairman of the board and CEO of CEZ.

The thermo-electric power plant discussed here is the only thermo-electric power
plant in Montenegro with an installed capacity of 210 MW; it covers roughly 40%
of the power production in Montenegro. The annual consumption of electricity in
Montenegro reaches approximately 4.5 TWh of electric energy, about two-thirds of
which are imported from surrounding countries.
