The Sagorsk pumped storage power plant ( Russian Заго́рская гидроаккумули́рующая электроста́нция ) is the only pumped storage power plant in Russia . It is located near the city of Sergiev Posad (which was called Sagorsk from 1930 to 1991 ) in Moscow Oblast . It is located 67 km from Moscow on the Kunja River and is owned by the RusHydro / Mosenergo energy company based in Moscow.
Sagorsk-1 power plant
The decision to build the first Russian pumped storage power plant (also known as the Sagorsk-1 power plant ) was made in 1974. In December 1987 the first two reversible pump turbines went into operation, the power plant reached the full output of 1200 MW in turbine operation and 1320 MW in pump operation in 2000 with now six Francis turbines . The upper basin is formed by a ring dam and the lower basin is the Kunja, a tributary of the Dubna . The height of fall between the upper and lower basins is only 100 m, which is comparatively small for pumped storage power plants. The six pressure pipelines each consist of 18 segments with a length of 40 m and a diameter of 7.5 m. The connection to the power grid is via a 500 kV switchgear. In 2004, the Sagorsk power plant was the eighth largest pumped storage power plant in the world in terms of installed turbine capacity.
Sagorsk-2 power plant
The Sagorsk-2 power plant is currently being built in the immediate vicinity of the existing Sagorsk-1 power plant . Four turbines from the manufacturer Silowyje maschiny (in which Siemens is also involved) with an output of 210 MW each are planned. Work on this began in 2007. It was originally assumed that the first two turbines should go into operation in 2010 and the other two in 2012. In the meantime, it is assumed that Zagorsk-2 will be completed in 2014 [obsolete] . Sagorsk-2 will have an output of 840 MW. At the start of construction in 2007, construction costs totaling 850 million US dollars were named. The connection to the power grid is to take place via a 90 km long 500 kV extra-high voltage line.
A serious incident occurred on the night of September 17-18, 2013: In the advanced stage of construction, after the generators and turbines had already been delivered, massive amounts of water penetrated the building. The cause is suspected to be subsidence . The incident could have caused major damage and potentially cause the completion of Sagorsk 2 to be significantly delayed. No one was harmed in this incident.
