Groundbreaking Ceremony of the “Lachin” Junction Substation

On September 21, President of the Republic of Azerbaijan Ilham Aliyev attended the groundbreaking ceremony for the 110/35/10 kV “Lachin” junction substation to be built by AzerEnergy Open Joint Stock Company in the city of Lachin and laid the foundation of the substation. While informing the head of state about the “Lachin” junction substation, the president of AzerEnergy Open Joint Stock Company Baba Rzayev stated that in order to connect the city of Lachin and surrounding villages to the common energy system of Azerbaijan, and to provide an uninterrupted and sustainable supply of electricity the digital substation is planned to be built at the southern entrance to the city which will be constructed according to a project agreed with the Committee for Urban Planning and Architecture.

The substation with a total capacity of 80 megavolt-amperes will perform a node function. Thus, a 110-kV double-circuit line from the “Shukurbeyli” substation in Fuzuli to the “Jabrayil”, “Zangilan”, “Gubadli” substations, and from there to the “Gulabird” hydroelectric power station, a 110-kV double-circuit line from the “Dashkesan” substation to the “Kalbajar” and “Gorchu” substations, as well as a 110-kV double-circuit line from the “Shukurbeyli” substation to the “Fizuli” and “Shusha” substations will be connected to the “Lachin” city substation. Thus, a circular electric power supply for substations built after the 44-day Patriotic War in Karabakh and East Zangezur, as well as newly-built two-circuit high voltage lines with a length of more than 400 kilometers will be created. If an accident occurs in one of the high-voltage lines located in the liberated territories, then the voltage will be immediately supplied through the lines coming from another direction. So, there will be no power outages in Karabakh and East Zangezur.

At this substation which is of strategic importance, a Control Center equipped with modern systems of digital control, security, and microprocessor-type automation, direct and alternating current devices, 35-kV and 10-kV closed switchgears, as well as 110-kV open switchgear consisting of the most modern equipment will be created, and a special dormitory building will be built for working personnel. To monitor the operation of the substation in real time and to transfer indicators to the SCADA system of “Azerenergy” OJSC, a local micro-SCADA dispatch control system will be established and the center of the energy system will be integrated into the SCADA system. In order to ensure fire safety at the “Lachin” junction substation, a pumping station, a fire basin, an emergency oil collector, fire protection and fire alarm systems will also be installed.
