Union for the Co-ordination of Transmission of Electricity

The Union for the Co-ordination of Transmission of Electricity (UCTE) is an association of electricity distribution network operators in Continental Europe. It operates a single phase-locked 50 Hz mains frequency electricity grid that supplies over 400 million customers in 22 countries, including most European Union members. It was founded in 1951 as the "Union pour la coordination de la production et du transport de l’électricité" (UCPTE) and was converted in 1999 into UCTE due to the EU deregulation of the electricity market.

Current (as of 2007) UCTE members are::Belgium, Germany, The Netherlands, Luxembourg, France, Spain, Portugal, Switzerland, Italy, Austria, Slovenia, Croatia, Poland, Slovak Republic, Czech Republic, Hungary, Western Ukraine, Bosnia and Herzegovina, Serbia, Montenegro, Former Yugoslav Republic of Macedonia, Greece, Romania, Bulgaria, Denmark (western part)
