ABB has completed the first Nordic-Baltic transmission grid interconnection, improving the reliability and efficiency of electricity supplies in Europe.
The Estlink connection between the 330 kV substation at Harku in Estonia and the 400 kV substation at Espoo in Finland is one of the priority projects in a European Union plan to improve cross-border power infrastructure, reduce blackouts and help create more efficient power markets in Europe. An estimated 2 TWh of electricity will be delivered anually into the Nordic electricity market from Baltic generation.
The partners in the Estlink project are the three Baltic power utilities – Eesti Energia, Latvenergo, Lietuvos Energija – as well as Pohjolan Voima and Helsinkin Energia of Finland.
The 105 km underground and underwater HVDC link was designed, built and installed by ABB using its HVDC Light technology in a record 19 months using modular construction.
The project, which was announced in late April 2005, is worth $110 million for ABB.
