Substation "Vostochnaya", Power distribution facility in Leningrad Region, Russia

Substation Vostochnaya is a high-voltage power distribution facility in the Leningrad Region of Russia, operating at 330 kV. It connects several transmission lines within the regional electricity network.

Substation Vostochnaya was commissioned in 1964 as a key link of the Leningrad energy system. In January 2007 two additional autotransformers and about 30 units of 330 kV equipment were put into service. A comprehensive reconstruction completed by 2011 equipped it with modern apparatus, and since 2013 it has formed part of the Saint Petersburg Energy Ring.

Since 2013 the substation has been part of the Energy Ring of Saint Petersburg, a 330 kV loop around the city. Its name, Vostochnaya ("Eastern"), refers to its position on the eastern side of the ring. The site lies between the village of Novosergievka and the 7 km railway platform.

This is an active industrial site with no public access. Only authorized personnel are permitted on the grounds.

Before 2022, this facility was one of the few direct electrical links between the Russian and Nordic grids. The physical connection still exists, but it now carries no power.
