The Visegrad region shares the CENTREL electricity system, which links the Czech Republic, Slovakia and Hungary. In 1995, the CENTREL system was connected with Western Europes grid. Poland also has electricity connections with Ukraine and Belarus. Currently, both north-south and east-west connections are being expanded, as part of the EUs Trans-European Energy Network project, including a new link to Lithuania. The four countries of the region are also members of European electricity transmission system Union for the Coordination of Transmission of Electricity (UCTE). UCTE coordinates the interests of transmission system operators in 20 European countries.
