Volkhovskaya is the first hydropower plant to be built under the Soviet Union's Electrification State Program (GOELRO) in 1926. Power Machines said the plant is a historical monument of Russian science and engineering.
Power Machines is to manufacture and supply a turbine and generator, modernize controls and excitation, and implement an automatic process control system using microprocessor control panels. The 9-MW unit is to be increased to 12 MW upon completion in 2008.
Volkhovskaya has five 9-MW units and three 12-MW units. The 12-MW units were rebuilt in the 1990s.
Power Machines said it and TGC-1 were studying the possibility of rebuilding the other four 9-MW units. It said they also were studying possible reconstruction of two units of the 99-MW Nizhne-Svirskaya hydroelectric project.
TGC-1 was registered in 2005 to involve 56 power plants in four regions. Its hydro projects, by region, include:
o St. Petersburg and Leningrad Oblast: Volkhovskaya; Vuoksinskiye Cascade including 94-MW Lesogorskaya and 70.3-MW Svetogorskaya; and Nizhne-Svirskaya;
o Karelian Republic: 24-MW Segozierskaya (proposed for commissioning 2013-2015); 86.8-MW Beloporozhskaya (proposed for commissioning 2013-2017: 25.6-MW Kondopozhskaya; several small hydros;
o Murmanskaya Oblast: Nivskie Cascade including 60-MW Niva 2 and 155.5-MW Niva 3; and Pazskie Cascade including 11.2-MW Kaitakosky and 30.5-MW Yaniskoski.
