Construction of converter station for submarine cable commencing in Rauma

ABB in Sweden carries responsibility for the overall contract for the converter station of the DC link. The manufacture and testing of the subsystems is in progress at ABB’s factory in Ludvika. The contract covers earthwork, new valve facility, DC converters with foundations, DC and AC bays with their devices, and the control and protection system of the link. The construction work is carried out by Skanska.

Construction work at the opposite station at Finnböle in Sweden began in March 2010. The Fenno-Skan 2 submarine cable project has progressed well on schedule. The capacity of the transmission line between Rihtniemi and Rauma in Finland was raised at the end of 2009, and the electrodes were replaced at Lautakari in Pyhämaa. The construction of the transmission line in Sweden between Dannebo and Finnböle is in progress. The manufacture of the submarine cable commenced in Halden in Norway at the end of last year.

Fenno-Skan 2 will be an 800 megawatt and 500 kilovolt electricity transmission connection between Finland and Sweden. The connection will be a direct current link. The total length of the link will be approx. 270 kilometres, of which the actual submarine cable will account for some 200 kilometres. The extension will be carried out in co-operation between Fingrid Oyj and Svenska Kraftnät. The project will increase the electricity transmission capacity between the two countries by 40 per cent.
