Reconstruction Project for the Tusimice Power Plant to be Prepared by Skoda
Praha

Today, CEZ and Skoda Praha signed a Contract for Work related to the project
design for the total reconstruction of the Tusimice II Power Plant. The work
includes the preparation of the complete project documentation for the initial
project by the end of the year.

The overall reconstruction of the Tusimice plant will result in the replacement
of the current capacity of 4x200 MW by a new technology with an economic life of
up to 25 years. For such period, the Libous mine in the vicinity of the plant
will provide a sufficient volume of coal within the current local exploitation
limits.

SKODA PRAHA a.s. was the general supplier of virtually all heat and nuclear
power plants in the Czech Republic and Slovakia. The company also has reference
in many countries of four continents. Last year, Skoda Praha became a fully
consolidated part of the CEZ Group, with CEZ increasing its share in Skoda Praha
to 97.6% at the beginning of March.

"Skoda Praha was also the general supplier of the existing Tusimice plant;
therefore, it is acquainted with its current shape," said Jiri Borovec, Director
of CEZ and Head of Production Division.

The new power plant will be equipped with state-of-the-art boilers with higher
efficiency of blocks (38% in aggregate) than the current power plant (which has
a 33% efficiency). As a result, and thanks to other measures, the environmental
parameters of the new plant will improve significantly. "When compared to the
current condition, which fully meets all stringent EU standards, the 'new'
Tusimice will further reduce all emissions. As the desulphurized combustion
products will be directed to cooling towers, no chimney is required," Otakar
Rydl, Head of the Recovery of Sources Division, pointed out. In comparison with
the current situation, the new technology will reduce CO2 emissions by 15%, SO2
emissions by 70%, NOx emissions by 65%, and ash emissions by 40%.

According to CEZ plans, the construction work aimed at the overall
reconstruction of the first two blocks of the plant is scheduled to commence in
the 2nd half of 2007, and the other two in mid-2009. The commissioning of the
new plant is scheduled for early 2009 or the end of 2010. The aggregate
investment is estimated at CZK 15 billion.

The majority of the existing power plants of CEZ were constructed in the late
1960's and early 1970's. Ten years ago, they were desulphurized and refurbished,
which extended their economic life by another 10-15 years. This means that the
economic life of the majority of them will end in the period between 2010 and
2015. Reconstruction of a specific power plant depends mainly on the volume of
coal sufficient for its entire economic life. "In the event of an entirely new
power plant, coal is required to be available for 40 years following its
commissioning; in the event of major reconstruction, including installation of
new technologies, the plant is expected to operate for 25 years," Jiri Borovec
explained. "However, with a view to limited coal resources, they cannot be
recovered to the current extent," he added.
