PRAGUE. JUNE 6. INTERFAX C.NTRAL EUROPE - The Czech Republic has enough resources to be a regional exporter of electricity until 2015, after which supply and demand will balance out and the country will have to extend its nuclear power production capacities in order to sustain supply long-term, director of Czech Industry and Trade Ministry's electricity department Ladislav Pazdera told Prague-based conference Energy Trading in Central and Eastern Europe Wednesday. "[Extension of current nuclear capacities] is not a question of if but when, whether it will be in 2020 or 2025," Pazdera said. He said the timing will depend on whether or not companies will manage to overcome zoning limits banning them from exploiting 1,293 tonnes of yet untapped resources of brown coal. Prague-and Warsaw-listed Czech state-controlled power utility CEZ currently operates two nuclear plants Dukovany and Temelin. He also said that the Czech government is opposed to the idea of creating a single energy market regulator on the European Union level but would back a middle regulatory body. "We support the idea of giving some more competence to some regulatory body but not giving regulatory powers to the European Union," Pazdera said.
