LitPol Link is an electricity link between Poland and Lithuania which connects the Baltic power systems to the Continental Europe Synchronous Area. It has a capacity of 500 MW and since 2025 operates in a synchronous regime.[2]

History

[edit]

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.[3] The connection is expected to increase Poland's electricity interconnection level from 2% to 4%.[4] Parts of LitPol are on the EU "Projects of Common Interest" list in November 2015.[5]

On 29 September 2006 Polish President Lech Kaczyński and Lithuanian President Valdas Adamkus signed a joint declaration on the joint power grid project during their meeting in Warsaw.[6] The memorandum of understanding to establish a joint interconnection operator was signed between Lietuvos Energija and Polish PSE in Vilnius on 8 December 2006. Project Company Shareholding Agreement signed on 12 February 2008 in Warsaw.[7] The joint project company LitPol Link was founded on 19 May 2008.[8]

Aiming to build a 400 kV overhead line between Ełk and Łomża, PSE signed a contract with the Polish construction company PBE ELBUD Group on 12 September 2011.[9] In early 2013, the 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.[10]

Construction of the link commenced in the Alytus district on 5 May 2014.[11] LitPol electricity link started operations on 9 December 2015 the same day transmitting up to 200 MW power from Poland to Lithuania.[12]

Technical features

[edit]

The interconnection comprises a 53-kilometre (33 mi) double-circuit 330 kV line from Kruonis to Alytus, a 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 the Lithuanian side, and a 106-kilometre (66 mi) double-circuit 400 kV line from the border to Ełk on Polish side.[13]

According to the pre-feasibility study, the cost of the interconnection was estimated to be €237 million. With a view to enhancing existing energy infrastructure, including Poland–Germany and Poland–Czech Republic upgrades, the Polish TSO invested an additional €650 million and the Lithuanian TSO €262 million.[8] The Lithuania–Poland interconnection has been designated an EU Trans-European Networks project. The interconnection initial capacity is 500 MW, with a transmission capacity upgrade of up to 1000 MW possible after completion of a second HVDC back-to-back station.[14][15]

The tower 61 near Ełk, tower 160, tower 166 (both near Suwalki), and tower 293 near Sankury, have a height of 107 metres.[citation needed]

HVDC Back-to-back station

[edit]

Between 2015 and 2025, the line was connected to the HVDC back-to-back converter station, located in the Alytus, 600 metres (2,000 ft) southwest of the existing 330 kV-substation. It had two converters each rated for 500 MW transmission power. The facility is 200 metres (660 ft) long and 170 metres (560 ft) wide.[16] Following the synchronization with CESA, the line is connected to the transformers and operates in synchronous mode.

Project company

[edit]

LitPol Link was founded by PSE and Litgrid with equal stakes. The company is based in Warsaw.[14] Acting Managing Director of LitPol Link Mr. Artūras Vilimas.[17]
