is . The cable is constructed by ABB. The submarine cable was laid by Global Marine Systems using the Sovereign service vessel. The project cost €110 million. Sites Estlink 2 History A preliminary agreement on EstLink 2 was signed between Elering and Fingrid on 15 February 2010 in Tallinn. Capital investment decision by Fingrid was made on 20 May 2010. A construction agreement was signed on 1 November 2010. On 23 December 2010, the contract to manufacture and install the subsea and underground cables was awarded to Nexans, the contract to build converter stations was awarded to Siemens, the contract to build the Nikuviken cable terminal station and to expand the Anttila substation in Finland was awarded to Empower Oy, and the contract to build the transmission line between Anttila and Nikuviken was awarded to ETDE, a part of Bouygues. Laying of the cable started on 15 October 2012 and it is laid by the cable ship Nexans Skagerrak. The cable testing started on 22 October 2013. A trial operation started on 6 December 2013 and continued until 6 February 2014 after which it started commercial operations. It was officially inaugurated on 6 March 2014. Description The total length of Estlink 2 would be , including a long offshore cable, a long onshore cable in Estonia, and of overhead lines in Finland. The long underground cable starts at the Püssi substation and runs the coast of the Gulf of Finland at Aseri. From there the long offshore cable runs to the Nikuviken cable terminal station in Finland. The Nikuviken cable terminal station will be connected with the Attila converter station by the long overhead line. Estlink 2 will be a classic bidirectional monopolar high-voltage direct current connection with line-commutated converter thyristors. Its maximum transmission rate will be 650 MW and it will operate with a voltage of 450 kV. Its estimated cost is about €320 million, of which converter stations cost €100 million and cable €180 million. The European Commission has decided to allocate €100 million to the project. Sites Waypoints of overhead line in Finland Estlink 3 On June 28, 2022, Elering and Fingrid signed a memorandum of understanding to begin planning for a third submarine cable, EstLink3, with a capacity of up to 1000 MW, expected to be completed by 2035.
