Estlink 2

Estlink is a set of HVDC submarine power cables between Estonia and Finland, established to secure power supply and integrate the Baltic and Nordic energy markets. The first interconnection, Estlink 1, was launched in 2006 and connected the Estonian electrical system at the Harku converter station to the Finnish transmission network at Espoo converter station. Estlink 1 is a 105km-long, +/-150kV, 350MW HVDC link cable manufactured by ABB and laid by Global Marine Systems using the CS Sovereign. The project cost €110 million. In 2010, a preliminary agreement for Estlink 2 was signed, and construction began in 2012. The cable is laid by the Nexans Skagerrak and is expected to increase the capacity of the Estlink connection.learn more on wikipedia
