MOESK increases capacity and improves reliability of power supply in the south of Moscow

JSC “Moscow United Electric Grid Company” (belonging to the Rosseti Group of Companies) is carrying out a large-scale renovation of 220/110 kV “Avtozavodskaya” substation within the framework of implementation of the investment program. Central Electric Grids branch completed next stage of the facility renovation.

250 MVA Autotransformer (AT-2) was put into operation after being transferred from the old outdoor 110 kV switchgear to the new 110 kV gas-insulated switchgear and control gear. The works on reconnecting the cable lines from the old outdoor 110 kV switchgear to the new 110 kV gas-insulated switchgear and control gear are in progress.

After the renovation the substation capacity will increase from 500 to 660 MVA. This is particularly important given the location of the main substation. The substation supplies electric power to consumers in Southern Administrative District of Moscow including many socially and economically significant facilities, namely Office of the Federal Tax Service of the Russian Federation, Kolomenskoye Memorial Estate, Arbitration Court, Kolomenskoye district heating station, Moscow State Academy of Water Transport, State Road Traffic Safety Inspectorate for Southern Administrative District, “Sky Fort” residential complex, “Hudson” shopping mall, about 20 schools,over 20 kindergartens and polyclinics.

“All electrical equipment has a higher reliability, compactness and increased transmission capacity if compared to older models. The use of advanced technologies in production of the equipment made it possible for us to decrease operating costs, improve reliability and safety and extend the scheduled maintenance turnaround cycle,” said Vsevolod Ivanov, Director of Central Electric Grids of MOESK.

Renovation of Avtozavodskaya substation commenced in 2008. Its main objective was to increase capacity and reliability of the main substation. The total investments of the Company in the project will amount to RUR 3.8 billion. Modernization completion is scheduled for the end of this year.
