PROJECT OBJECTIVES
• Improvement of Armenian power system efficiency
• Increasing of the internal power transmission network efficiency
• Minimizing of the power transmission losses
• Increasing of power transmission reliability for regional
consumers
• Supporting to RoA sustainable economic development
• Ensuring of reliable, flexible and mutually beneficial cross-border
power exchanges between Armenian and Iranian power systems
WORKS TO BE IMPLEMENTED UNDER THE PROJECT
The project is planned to be implemented in two stages
starting from 2015. In the first stage it is planned to
rehabilitate “Agarak-2” and “Shinuhayr” substations by the
financing of ADB .
In the second stage it is planned to rehabilitate
“Yeghegnadzor” and “Ararat-2” substations, by the financing
of EBRD.
During the entire project implementation period (2015-2019)
the management and technical supervision of the construction
works will be financed by ADB.
EXPECTING RESULTS FROM THE PROJECT
After the project completion the efficiency of power system
operation and the reliability of power supply will be increased
contributing to the sustainable development of economy and
reduction of power transmission losses in power system.
The rehabilitation of existing (“Agarak” and “Shinuhayr”)
substations will improve the power supply reliability and
quality for urban and rural consumers.
“Agarak-2” 220/110/6kV substation should
be constructed instead of “Agarak”
switching point under the financing of ADB.
The following equipment will be installed at
“Agarak-2” 220/110/6kV substation:
• AT 220/110/6kV 125 MVA
• 6kV switchgear
•110kV circuit breaker
• 220/110kV disconnector
• overvoltage limiter
• current and voltage transformer
• relay protection and automation equipment and etc.
The completion of works is foreseen in 2018.
“Agarak-2” 220/110/6 kV substation will be constructed 385 km
far from the capital Yerevan. It will occupy 3,813 ha area and
will be located 150km far from ‘’Shinuhayr’’ substation. In
2002 “Agarak” switching point has been constructed in this
area.
It is foreseen to change 220kV
switchgear scheme to l, II and
transfer
busbar
system
by
the
rehabilitation
of
“Shinuhayr“
220/110/35/6kV substation. During
the rehabilitation the following
equipment should be installed:
• 220/110/35kV circuit breakers
• disconnectors
• current and voltage transformers
• overvoltage limiters
• 6kV indoor switchyard
• relay
protection
and
automation
equipment and etc.
“Shinuhayr’’ substation was built
in 1961. The installed capacity of
the
substation
is
271MVA.
The
substation is located on 235km far
from
the
capital
Yerevan.
It
occupies 6,6 ha area. In 2004 the

substation (financed by EBRD), the
following
equipment
will
be
installed:
• 110kV circuit breakers
• 220/110kV
current
and
voltage
transformers
• overvoltage limiters
• 35kV switchgear
• relay protection and automation equipment

substation was built in 1966. The
installed capacity of the substation
is
126
MVA.
The
substation
is
located 125km far from the capital
Yerevan. It occupies 3,55 ha area.
In 2004, 220/110kV substation was
partially
modernized
and
some
circuit breakers and disconnectors
were replaced with the new ones.
During
the
rehabilitation
of
“Ararat-2” 220/110/6kV substation
(financed by EBRD) the following
equipment should be installed:
• two
125MVA

transformers,
• 220 and 110kV circuit breakers,
• disconnectors,
• power and voltage transformers,
• surge arresters (overvoltage limiters),
•6kV indoor switchgear
• relay protection and automation equipment
The installed capacity is 126MVA.

“Ararat-2” 220/110/6kV substation
was built in 1975. The substation
is located at a distance far from
55km from Yerevan. It occupies
4,55 ha area. In 2004, 220kV
switchgear was partially equipped and
