Siemens Completes Estlink 2 Transmission Project

Siemens Energy completed the EstLink 2 project, a high-voltage direct current (HVDC) link consisting of converter stations in Anttila, Finland, and Püssi, Estonia. Power is now being transmitted by Fingrid, the transmission system operator in Finland and the Estonian transmission system operator Elering. The new joint transmission capacity between the two countries is now increased from 350 MW to 1000 MW. Siemens was responsible for designing the HVDC system as a monopolar connection with metallic return conductor. This turnkey project included delivering, installing and commissioning of the complete HVDC converter stations, excluding the overhead line and power cable part in between the stations. Total value of the converter station turnkey project was €100 million (approximately $137 million USD).
