The synchronous grid of Continental Europe (also known as Continental Synchronous Area; formerly known as the UCTE grid) is the largest synchronous electrical grid (by connected power) in the world. It is interconnected as a single phase-locked {{nowrap|50 Hz}} mains frequency electricity grid that supplies over {{nowrap|400 million}} customers in {{nowrap|24 countries}}, including most of the European Union. In 2009, {{nowrap|667 GW}} of production capacity was connected to the grid, providing approximately {{nowrap|80 GW}} of operating reserve margin.[1] The transmission system operators operating this grid formed the Union for the Coordination of Transmission of Electricity (UCTE), now part of the European Network of Transmission System Operators for Electricity (ENTSO-E). AreaThe synchronous grid of Continental Europe covers territory of the ENTSO-E Continental Europe regional group and some neighboring countries not involved in the ENTSO-E. The synchronous grid includes part or all of Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark (western part), France, Germany, Greece, Hungary, Italy, Luxembourg, Macedonia, Montenegro, the Netherlands, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, and Switzerland as a members of the ENTSO-E Continental Europe regional group. In addition to the ENTSO-E members, the small west electricity island of Ukraine is synchronized with the grid of Continental Europe. Albania is operating the national grid synchronously with the synchronous grid of Continental Europe. The grids of Morocco, Algeria and Tunisia are synchronized with the European grid through the Gibraltar AC link and form the SWMB. In April 2015, the grid of Turkey was synchronized with the European grid.[2] Although synchronous, some countries operate in a near island mode, with low connectivity to other countries. The European Commission considers high connectivity to be beneficial,[3] and has listed several interconnection projects as "Projects of Common Interest".[3] However, the national grids must also be upgraded to handle increased power flows if the values of a free energy market are to be realised in the EU.[4] List of electricity interconnection level{{external media| topic = |align=right | image1 =2011 interconnection levels, and 2020 plans }} Electricity interconnection as percentage (EIL = electricity interconnection level) of installed electricity production capacity in 2014; the EU has a goal of at least 10%.[5]
Electricity island networksThe British grid is not synchronized with the Continental Europe frequency, but it is inter-connected via the HVDC Cross-Channel link and BritNed to an electricity interconnection level of 6%.[5] Similarly, the Nordic regional group of ENTSO-E (former NORDEL), composed of Norway, Sweden, Finland and the eastern part of Denmark (Zealand with islands and Bornholm), is not synchronized with the Continental Europe, but has a number of non-synchronous DC connections with the Continental Europe grid. Gotland is not synchronized with the Swedish mainland, as it is connected by HVDC. The networks of Ireland and Northern Ireland form the ENTSO-E Irish regional group, which is not yet interconnected with the Continental Europe grid, but has interconnection with the British network through the Moyle Interconnector and the East–West Interconnector. Similarly, the network of ENTSO-E Baltic regional group, composed of Lithuania, Latvia and Estonia, currently part of the IPS/UPS system, is interconnected with the Nordic grid through the Estlink cables and the NordBalt cable, at an electricity interconnection level of 10%.[5] The Baltics are connected with the Continental Europe grid through the Lithuania–Poland interconnection. The networks of Iceland and Cyprus, are not yet interconnected with the other grids. Malta is connected up to 35% via the Malta-Sicily interconnector, commissioned in 2015. Future extension plansUCTE/ENTSO-E and the corresponding partner TSO companies are planning the following extensions of the grid and synchronous frequency:
Studies are made on the synchronous connection between the Continental Europe and IPS/UPS networks . Separately, there is another option concerning Ukraine and Moldova, and the ENTSO-E Baltic regional group – to disconnect only these networks from the IPS/UPS system and synchronously interconnecting them to the synchronized grid of Central Europe. Further possibilities are extension to the Nordic regional group, the Turkey-Iraq interconnection, and the DESERTEC concept for interconnection with other countries in the Middle East. In the past Armenia and Turkmenistan networks were part of the Soviet unified system, but currently they are connected to the Iran grid. See also{{Portal|Energy}}
