EstLink 2, a direct current interconnection between Estonia and Finland, has been made available for commercial operations. The EstLink 2 interconnection triples the transmission capacity between the two countries and significantly strengthens the integration of electricity markets in the Baltic Sea region. After the commissioning of EstLink 2, the transmission capacity between the countries has increased from 350 MW to 1,000 MW from Estonia to Finland, and to 860 MW from Finland to Estonia. The restriction on transmission capacity to Estonia will remain in place until the reserve power plant in Kiisa is commissioned in September 2014. The EstLink 2 interconnection is owned by the transmission system operators Fingrid and Elering. The total length of EstLink 2 is approximately 170 km, some 14 km of which is an overhead line in Finland, about 145 km a submarine cable laid on the bottom of the Gulf of Finland, and about 11 km an underground cable in Estonia. The total budget for the project is approximately €320m, divided between Fingrid and Elering. EstLink 2 has received €100m in investment subsidies from the European Union.
