Information about the project
“LitPol Link” is an electricity interconnection with neighbouring Poland that, for the first time, connected the electricity infrastructure of the Baltic States with that of Western Europe. This electricity transmission highway enabled the Baltic States to operate together with the energy systems of other Western European countries and contributed to the development of the European electricity market.
“LitPol Link” consists of a 500 MW, 400 kV high-voltage electricity transmission line from Ełk to Alytus. The total length of the overhead line is 163 kilometres: 51 kilometres run through Lithuania, in the Alytus and Lazdijai districts, and 112 kilometres through Poland, across the Podlaskie and Warmian-Masurian Voivodeships.
One of the key elements of the interconnection is located at the Alytus substation – a DC back-to-back converter that enables the synchronisation of the differently operated electricity transmission systems of Lithuania and Poland.
The 500 MW “LitPol Link” electricity interconnection has been in operation since the end of 2015. Its expected service life is 50 years, and the total project value is EUR 340 million.
