2nd line Slavetice (CZ) – Dürnrohr (AT)

400kV 2006 On the common towers with the existing line – V437

Further needs of the system: There is still the need of completing of the last section 400kV north-south link in Bohemia (to construct the 400kV line between the substations Cechy Stred and Bezdecin), supposed commissioning about 2008.

The construction of the 400kV line Krasikov-Horni Zivotice is planned by the year 2010 and 2nd circuit of 400kV line Prosenice-Nosovice about year 2011.

CONCLUSIONS

• CEE Region combines countries being a new members of EU and countries being just before accession in 2007. Most of these countries were connected to UCTE synchronous area many years before their formal accession that in general confirms relatively high technical level of their electrical power sectors and in particular their transmission networks.

• Transmission infrastructure of many countries of the CEE Region, expecially 400 kV network, is inadeqately developt and requires significant investments, within a period of coming 10 – 15 years, for internal technical improvement of the systems and theirs interconnection to neighboring UCTE and UPS/IPS countries,

• Countries like PL, H, SK and RO located at the border of the UCTE synchronous area are already or will be connected to UPS/IPS countries by radial, island areas or by back to back stations.

• Since significant increase in generating capacity is not assumed in the next 10 years, the security of electric energy supply within the CEE Region is directly related to development of power transmission infrastructure.
