On December 20, 2007, the Russian North-West Transmission Grids branch of OAO "UES FGC" brought on line the 330-kV Rzhevskaya Substation with overhead cable transmission lines. The new substation is the first power grid facility of this voltage class to have been built in Saint Petersburg and the Leningrad Region over the past twenty years. It will help improve the reliability of power supply in the north-eastern part of Saint Petersburg. The total amount of funds invested in the new substation project was RUB3.1 billion.
On 25 December, the Urals Transmission Grids branch completed the first phase (220- kV) of the 500-kV Yemelino Substation project. The substation will support the large-scale expansion project underway at the Seversky Pipe Plant and will provide 110 MW of capacity to the plant, thus making it possible to put into operation a modern electric furnace shop in mid-2008. The 500-kV Yemelino Substation project will be completed in December 2008.
