The Lithuania–Poland interconnection LitPol Link represents electricity link between the Baltic transmission system (part of the IPS/UPS system) and the synchronous grid of Continental Europe. As of 2016[update] the first stage of the project which has a capacity of 500 MW has been completed.
In 2000, European Commission and the EBRD agreed to finance a feasibility study on the Poland–Lithuania transmission interconnection. The study was completed in September 2002. The connection is expected to increase Poland's electricity interconnection level from 2% to 4%. Parts of LitPol are on the EU "Projects of Common Interest" list in November 2015.
On 29 September 2006 Polish President Lech Kaczyński and Lithuanian President Valdas Adamkus signed joint declaration on the joint power grid project during their meeting in Warsaw. The memorandum of understanding to establish a joint interconnection operator was signed between Lietuvos Energija and Polish PSE-Operator in Vilnius on 8 December 2006. Project Company Shareholding Agreement signed on 12 February 2008 in Warsaw. The joint project company LitPol Link was founded on 19 May 2008.
Aiming to build a 400 kV overhead line between Ełk and Łomża PSE-Operator signed a contract with the Polish construction company PBE ELBUD Group on 12 September 2011. During start of 2013 Lithuanian transmission system operator Litgrid awarded ABB Group a $110 million contract to supply and install the first HVDC converter station in proximity of Alytus, Lithuania.
Construction of the link commenced in the Alytus district on 5 May 2014. LitPol electricity link started operations on 9 December 2015 the same day transmitting up to 200 MW power from Poland to Lithuania.
The interconnection represents 53-kilometre (33 mi) double circuit 330 kV line Kruonis–Alytus, 1000 MW back-to-back converter in Alytus and 48-kilometre (30 mi) double circuit 400 kV line from Alytus to the Lithuania–Poland border on Lithuanian side and 106-kilometre (66 mi) double circuit 400 kV line border–Ełk on Polish side.
According to the pre-feasibility study cost of the interconnection estimated €237 million. With intention to enhance existing energy infrastructure including Poland–Germany and Poland–Czech Republic upgrades in addition Polish TSO invested €650 million and Lithuanian TSO €262 million. Lithuania–Poland interconnection has been listed as a EU Trans-European Networks project. The interconnection initial capacity is 500 MW with transmission capacity upgrade up to 1000 MW possible after completion of second HVDC back-to-back station.
The tower 61 near Elk, the tower 160, the tower 166 ( both near Suwalki) and the tower 293 near Sankury have a height of 107 metres.
HVDC Back-to-back station
The Alytus HVDC back-to-back station is located 600 metres (2,000 ft) southwest of the existing 330 kV-substation which has been extended as well. It consists of two converters each rated for 500 MW transmission power. The facility is 200 metres (660 ft) long and 170 metres (560 ft) wide.
