<> CJSC





In pursuance of the order N12 dated 20.01.1997, of Ministry of Energy of RoA, proceeding from the improvement necessity in Energy System of RoA, "High Voltage Electrical Networks" as a subsidiary company was established in the structure of "Armenergo" State Enterprise on 30.06.1997.

Based on the decision N450 dated 20.07.1998 of the Government of RoA, "High Voltage Electrical Networks" CJSC (HVEN CJSC) was established on 21.08.1998 in a way of reorganization of subsidiary company as "High Voltage Electrical Networks" CJSC.
The main objects and goals of HVEN CJSC are the transmission of energy via 220-110kV electrical networks, existing in the balance of HVEN CJSC.

The problems of HVEN CJSC are as follows:

  • The implementation of 220-110kV electrical networks service operation, maintenance, reconstruction, retooling and design works.
  • The extension and development of transmission networks.
  • The construction of energy facilities and high voltage transmission lines.
    • The providing of OHL and substation equipment operations without failure and readiness to bear the requested load.

• The providing of safety work, and the arranging the preparation and improvement of professional qualification of personnel.

110-220kV electrical networks

In the balance of HVEN CJSC as on 01.01.2004. there are 15 substations of 220kV, in which the total power of installed 36 power transformers is 2750.0 MVA and one "Agarak" 220kV Swithching Point, 110-220kV OHL with 1870.24km long, including 330kV -164.0km long, 220kV-1301.13km long and 110kV-405.11km long as per design clearances.
The capacity of power transformers, installed and being under operation at the substations, satisfies the transmission of consumed electrical energy.

Energy system of RoA via "Agarak" 220kV Swithching Point is connected with Energy system of IRI by "Ahar- 1,2" 220kV interstate lines, and by "Alaverdi" 220kV, "Lalvar" and "Javakhq" 110kV OHL are connected with energy system of Republic of Georgia.

The highest and the lowest towers as per territory.

N80 tower of "Meghri" 220kV OHL. is the highest tower of HVEN CJSC, which is situated in 2717m height in Guliberd mountain pass, Aramazd and Katar mountains tips saddles of Bargushat mountain range.

N1 tower of "Ahar- 1,2" 220kV OHL at beach of Araks river is the lowest tower by 550m height.
