                    CEZ GROUP ENTERS HUNGARIAN ENERGY MARKET

Today, the CEZ Group officially opened a branch office in Budapest, to support
and promote its Hungarian activities. The Hungarian office further enhances the
business network of the CEZ Group which currently covers, aside from the Czech
homeland and Hungary, also Germany, Poland, Slovakia, Bulgaria, and Romania. For
the nearest future, the CEZ Group plans branch offices also in other countries
of Southeastern Europe.

"CEZ has clearly conveyed its vision to become Number One in the power market in
Central and Southeastern Europe. But this expansion consists not only of the
acquisition of new subsidiaries - we also follow the path of developing our
business and trade. We believe that today's opening of this branch office of CEZ
majorly enhances the electricity offer for traders, distributors (utilities),
and consumers (final customers) on the Hungarian market," said Martin Roman,
Chairman of the Board and CEO of CEZ, on occasion of the opening ceremony.

The Hungarian spin-off of the CEZ Group already acquired all necessary trade
licenses and finalized its first deal in May. "Our goal is to acquire, and then
consolidate, a strong position as player in the Hungarian market. In a first
stage, we will focus not only on domestic trading, but also on cross-border
electricity sales," adds Gabor Hornai, Branch Director of the Hungarian office
and long-term expert for the Hungarian energy market.

The CEZ group has been conducting its foreign expansion with success, both in
the area of electricity distribution and as regards the acquisition of
production sites. Since January 2005, the corporation owns three Bulgarian
distribution companies, and towards the end of last year, CEZ secured also the
Romanian distribution company Electrica Oltenia, which supplies those areas with
electricity that are in the immediate neighbourhood of the Bulgarian catchment
area for distribution of the CEZ Group. In the area of power generation, CEZ has
recently completed the acquisition of two Polish power companies, Elcho and
Skawina; at the beginning of May, the corporation executed the privatization
agreement on the purchase of the Bulgarian heat power plant Varna.
