The main stage of a comprehensive upgrade of one of the biggest power centers in the Republic of Dagestan, 330 kV Derbent substation, is complete. A new power transformer has been installed and new generation of 330 kV switching equipment implemented. The upgrade is ongoing along with a project of building a 171.7 km 330 kV Artem – Derbent overhead line that will improve the reliability of power supply over the whole south of the region, including railway facilities of JSC ‘RZD’ and oil pumping stations, and international transit of power to the Republic of Azerbaijan. The total cost of work is over 6.9 bn rubles.

The substation's 125 MVA autotransformer has been replaced with one of higher capacity, 200 MVA. The second autotransformer will be commissioned before end of 2020, raising the facility's capacity from 282 up to 432 MVA. The new power units are provided with an energy-efficient cooling system and a firefighting fine water-spray module. Such design allows eliminating fire within the shortest time with minimum consumption of water.

Due to the complicated terrain of the land, a 330 kV gas insulated switchgear (GIS) has been mounted at the substation. This is the first application of such equipment in Dagestan. GIS has a number of benefits compared to switchyards; e.g. it is highly reliable, firesafe, environmentally friendly, and has a footprint three times smaller. The GIS service life is 50 years.

Also, microprocessor-based relay protection and emergency control automation suites have been implemented. 

The Derbent 330 kV substation upgrade is joined with the 330 kV Artem – Derbent overhead line construction project. It is part of the Comprehensive Backbone Infrastructure Upgrade and Expansion Plan approved by order of the Russian Government no. 2101-r dated September 30, 2018.
