The following information was filed by CEZ, a. s. in Czech language with the
Prague Stock Exchange as required by its rules and regulations:

Report No. 1:

TEMELIN TO PURCHASE NUCLEAR FUEL FROM RUSSIAN TVEL

As of 2010, Russinan TVEL will become a new supplier of nuclear fuel to Temelin
Nuclear Power Plant. In the same year, a contract with American Westinghouse
will terminate. Today, the representatives of CEZ, a. s., and Russian TVEL have
signed a contract for the supply of nuclear fuel for two VVER-1000 reactors of
Temelin Nuclear Power Plant. Namely, the contract was signed by Jiri Borovec,
Vice-Chairman of the Board of Directors and Head of Generation Department, and
Daniel Benes, Vice-Chairman of the Board of Directors and Head of Administration
Department, for CEZ, and Anton Badenkov, TVEL Deputy President, for TVEL.

CEZ selected the new supplier of fuel for Temelin in a tender in which also the
present supplier, i.e. Westinghouse, participated, besides TVEL. The contract
provides for the supplies for both units for the following 10 years, i.e. until
2020. During the term of the contract, TVEL is supposed to supply approx. 400
tons of fuel. The aggregate contract value is several billion Czech crowns.

Cooperation with TVEL as a supplier of fuel to Czech nuclear power facilities
comes as nothing new. TVEL is a long-time supplier of fuel to another Czech
nuclear power plant in Dukovany.

In one reactor of Temelin Nuclear Power Plant, there are 163 fuel units in total
containing 92 tons of fuel. Annually, approx. 1/4 of fuel, i.e. 40 units (23
tons of fuel), is replaced.

Czech nuclear power plants generate nearly 42% of the electric power production
in the Czech Republic. In 2005, Dukovany and Temelin Nuclear Power Plants
generated 24.7 TWh of electric power.
