Vyborg HVDC scheme, Electrical power transmission station in Leningrad region, Russia
Vyborg HVDC scheme is a power conversion station near Vyborg that links Russian and Finnish electrical grids together. The facility contains four converter blocks that transform electricity between two different voltage systems to enable the exchange.
The first three converter blocks were installed in the early 1980s to enable cross-border electricity supply. A fourth block was added in 2001 to increase the transmission capacity of the station.
The station represents a milestone in international energy cooperation between Russian and Finnish power systems during the late twentieth century.
The station is located near the Finnish border area and forms part of critical energy infrastructure. Keep in mind that this is a highly specialized industrial zone that is generally not open to the public.
When completed, the installation was the world's largest station of this type, until another facility in Saudi Arabia took the title in 2009. This early achievement made it a milestone in international power transmission technology.
