1. Background/Objective of the Project
For the people in Iraq, the Iraqi government at its maximum effort has been rehabilitating, building
and upgrading the infrastructures which were destructed or exhausted in the periods of the wars and
economic sanction since such periods ended. The power sector is one of those infrastructures which
are essential for the life of Iraqi people and is needed to be improved immediately.
As for the electricity situation, it is estimated that the power demand will be reached 30,000MW in
2020 from 20,000MW in 2015.
As one of solutions to enhance the power supply, the Ministry of Electricity, Iraq (MOE) plans to
convert the existing simple cycle gas turbine (SCGT) power stations to the combined cycle gas
turbine (CCGT) power stations, which is called the Add-On project (Add-On Project). Based on
this, in May 2015, MOEs expectation for the feasibility study for the Add-On Project was shown.
In this study, one site was selected for Add-On Project with the consideration of suitability and
priority of three (3) candidate sites (i.e. Amara, Nasiriyah and Najibiyah) through the meeting. And
the feasibility study of Add-On Project for selected gas turbine power station was carried out.
2. Financial Situation in Iraq
Iraqi Government has currently faced financial stringency because of the less national budget due to
the slump of crude oil price and the increase of costs/expenses for cleaning operation by Iraqi army
against terrorism (called by themselves as Islamic State for Iraq and Syria ISIS).
The World Bank and the International Monetary Fund (IMF) decided to provide Iraq with
financial supports. However, those financial supports are not enough and each ministry in the Iraqi
Government has to find out appropriate solutions to cover such situation.

3. Outline of Add-On Project
Basic Concept:
The principle of the combined-cycle is firstly to recover the exhausted gas and generate the
steam by the heat recovery steam generator (HRSG) and secondly to combine the steam and
generate the electricity by the steam turbine generator (STG). After completing the gas turbine
cycle (simple cycle), the temperature of the exhausted gas from the gas turbine which is wasted
in the simple cycle is still high enough to generate the steam. By recycling this exhausted gas,
the overall net efficiency of the combined-cycle may achieve at more than 50% from the
simple-cycle at around 35%-40%. This recycling of the waste entropy can expand the power

capacity without increasing the fuel consumption and the environmental load. Especially, to add
the HRSG and STG on the existing/operating simple-cycle power plant is called Add-On also
known as repowering or bottoming.
Site Selection:
The study has initially considered three (3) potential sites where the gas turbines are already
installed or planned to be installed in simple cycle and one of them could be converted to a
combined cycle plant.
Three sites proposed by MOE of Add-On
Site Amara Nasiriyah Najibiyah
Governorate Missan Thi Qar Basrah
Gas Turbines number 4 units x 125 MW 4 units x 125 MW 4 units x 125 MW
Simple Cycle PS In operation Planned, Not started In operation
Note: All three (3) sites utilize four (4) gas turbines of General Electric (GE) make, Frame 9 E type
or plan to install.

S-5
Location of Candidate Gas Turbine Power Station
The power stations at Amara and Najibiyah have been completed and the gas turbines in simple cycle
mode are in commercial operation. At Nasiriyah site, the gas turbines have not been yet installed
however the EPC contractor has been selected and the installation works are expected to commence in
early 2016 and be completed in 25 months from thereafter.
The site of Najibiyah has been ruled out for Add-On because there is no extra land available for
accommodating the equipment needed for the conversion into combined cycle. As the sites of
Nasiriyah and Amara have adequate extra land and they have been compared. The site of Nasiriyah
has been selected for this study because of the vicinity of the river water (Euphrates) which ensures
availability of the water to the power station, in the required quantity and with lower pumping costs.

4. Implementation Schedule
The implementation of the Add-On Project is envisaged to start once the simple cycle gas turbine
power station is completed, as follows. The Project Implementation Time Schedule (Base) is
attached.
Simple cycle gas turbine power station poject starts in early 2016, lasts 25 months and end in first
quarter of 2018
The Add-On Project will start at 2nd
quarter of 2018 and last 33 months therefore will be
completed by end of 2020
As alternative, upon MOEs request, another implementation schedule has been studied in order to
anticipate the Add-On Project early completion. The Project Implementation Time Schedule
(Alternative) is attached.
The concept is to start some engineering and procurement activities of the Add-On Project 3
months ahead of the simple cycle gas turbine power station completion.

Technology Advantages of Japanese Companies
The main purpose of the Add-On project is to increase the output comparing with simple cycle and
to achieve the higher efficiency to reduce the fuel consumption. In this regards, Japanese leading
equipment companies have many experiences to optimize the steam cycle in accordance with
specific condition such as in Iraq and to develop the equipment model. Moreover, the utilization of
steam exhaust from existing Gas Turbine efficiently is one of the important parts of which many
Japanese leading equipment companies including companies who do not manufacture Gas Turbine
have accumulated their technology for a long time. Therefore, Japanese leading equipment
companies are expected to contribute a lot toward optimization of model and cycle like this project.
5. Conclusion
The electricity demand in Iraq has been rapidly increasing however the electricity supply has not met
such demand. Considering the situation in Iraq and current circumstances around MOE, it is
understood that the Add-On project for Nasiriyah Gas Turbine Power Station is very appropriate
solution because this is the project which is possible to realize and materialize under the current
situation and circumstances in Iraq. Furthermore, consideration of utilization of JBIC buyers credit
scheme + EPC is expected because the construction cost as EPC basis can be economical than IPP
basis.

in operation of whole of electrical power system from generation, transmission, distribution and
collection of electricity bill from the consumers.
The organization chart of MOE is as shown in Figure 1-1 below. As of January 2016 Mr. Qassim
Mohammed Fahdawi is the Minister of MOE.
(Figure 1-1 / Organization Chart of MOE)
(Source: MOE)
1-2. Electricity Supply and Demand:
The actual generation output at the end of 2013 was around 11,000MW against the demand
16,000MW. In 2013, the electricity supply form the national grid to Iraqi people was around 16
hours per day.
And, it was increased up to around 12,000MW in 2014, however it is expected that the demand in
2018 will be over 20,000MW.
1-3. Power Stations:
The design capacity of the power station in the whole county in 2013 was around 22,000MW which
are steam (6,000MW), gas (11,700MW), Hydro (1,800MW) and Diesel (2,400MW). According to
MOEs explanation in the Iraqi Power Conference in London in June 2014, it is expected to add

2. Current Circumstances MOE has faced
2-1. Lack of Budget
The national budget of Iraq heavily relies on the amount and its price of exporting of crude oil
because around 90% of national revenue is come from the revenue of exporting of crude oil. The
Table 1-2 shows the national budget of Iraq and the planed oil price/export volume.

1-4
Due to trend of decreasing of oil price recently, the amount of national budget is very much
negatively affected and the allocation of yearly budget to ministries for reconstruction and
development projects has been decreased accordingly. As reference, the oil price as of January 2016
is around USD30 BPD.
2-2. Unstable Security Situation
In June 2014, Iraq was attacked by terrorism (called by themselves as Islamic State for Iraq and
Syria ISIS) and some cities in northwestern area of Iraq were occupied and controlled by them.
Iraqi army has been conducting cleaning operations against ISIS continuously and succeeded to push
them back in some areas, however threat and attacks by ISIS have been continuing unfortunately.
Because of those situations, Iraqi Government is obliged to spend huge amount to sweep ISIS, and
the budget for rehabilitation, reconstruction and development projects in the country was very much
decreased, which also makes further delay of necessary planned reconstruction projects in current
and future. The Figure 1-2 shows the control of terrain in Iraq as of November 2015.

2-3. Financial Situation in Iraq
As mentioned above, Iraqi Government has suffered two kinds of negative impact and has been
facing the situation of financial stringency at the moment. Therefore, in order to cover the negative
financial situation, the World Bank and the International Monetary Fund (IMF) decided to provide
the country with financial supports. However those financial supports are not enough and each
ministry is in the situation that ministry cannot implement by Iraqi national budget and they have to
find out suitable solutions such as utilizing foreign finance arranged by foreign institutes on their
reconstruction and development projects to be proceeded with the implementation of the necessary
projects.
3. Gas Turbine Power Stations in South of Iraq

3.1 Background and Objective
For the people in Iraq, the Iraqi government at its maximum effort has been rehabilitating, building
and upgrading the infrastructures which were destructed or exhausted in the periods of the wars and
economic sanction since such periods ended. The power sector is one of those infrastructures which
are essential for the life of Iraqi people and is needed to be improved immediately.
The Ministry of Electricity, Iraq (MOE) has been executing a lot of projects which rehabilitate
and newly install the power stations, substations, transmission lines, distribution lines and other
necessary projects to increase the power supply resources and provide enough electricity for all
through the country.
As one of solutions to enhance the power supply, MOE plans to convert the existing simple cycle
gas turbine (SCGT) power stations to the combined cycle gas turbine (CCGT) power stations.
The principle of the combined-cycle is firstly to recover the exhausted gas and generate the steam
by the heat recovery steam generator (HRSG) and secondly to combine the steam and generate
the electricity by the steam turbine generator (STG). After completing the gas turbine cycle
(simple cycle), the temperature of the exhausted gas from the gas turbine which is wasted in the
simple cycle is still high enough to generate the steam. By recycling this exhausted gas, the overall
net efficiency of the combined-cycle may achieve at more than 50% from the simple-cycle at
around 35%-40%. This recycling of the waste enthalpy can expand the power capacity without
increasing the fuel consumption and the environmental load. Especially, to add the HRSG and STG
on the existing/operating simple-cycle power station is called Add-On also known as repowering
or bottoming.
MOE has purchased total 72 units equal to 10,442MW of gas turbines from General Electric
(GE) and Siemens that is called the Mega Deal. More than 90% of the Mega Deal gas turbines
have been already installed as the simple cycle power stations by the end of 2015.
Based on the conceptual plan of the combined cycle conversion mentioned above, MOE has been
discussing with the IPP developers to realize the projects. However, it is assumed that the total cost
in IPP paid by MOE as tariff should exceed the total cost in investing by MOEs own for EPC even
though MOE would utilize the foreign finance on the projects. Therefore it is highly recommended
to MOE that MOE would consider the EPC to be financed by foreign institutes (EPC+Finance)
besides the IPP as alternative. As the recommendation of the EPC+Finance, in May 2015, MOEs
expectation for the feasibility study for the Add-On project (Add-On Project) was shown.

3-3
MOE had provisionally shortlisted three (3) sites in the south region of Iraq where SCGT power
stations either exists or are planned, out of which one of the most suitable sites to be converted to a
CCGT power station. Among three (3) candidate sites, Nasiriyah (Thi Qar Governorate) has been
selected by the discussion with MOE for this feasibility study.
Under this Add-On Project, individual HRSG will be installed behind each of the existing gas
turbines. The exhaust from each gas turbine will be led to the HRSG via individual diverter damper
installed in by pass stack. The proposed arrangement will allow simple cycle as well as combined
cycle operation of the plant. The diverter dampers along with the guillotine dampers for all four (4)
gas turbines shall be installed for safe maintenance of the HRSG while the gas turbine is operating in
simple cycle mode. The HRSG will be of horizontal design employing natural circulated evaporator
sections. The HRSG comprises of HP and LP drums together with respective economisers,
evaporators and super- heaters.

Steam from the four (4) HRSGs will be connected to one (1) number HP/LP steam turbine having
down flow exhaust arrangement exhausting the steam into a water cooled condenser (WCC), thus
constituting an Add-On Block of 4-4-1 configuration.
Generator of steam turbine will be connected to a dedicated step-up transformer for power
evacuation at 400kV level using existing 400kV GIS.
3.2 Contents and Technical feasibility
3.2.1 Site Selection
The study has initially considered three (3) potential sites where the gas turbines are already installed
or planned to be installed in simple cycle and one of them could be converted to a combined cycle
plant:
Table-1: Three sites proposed by MOE of Add-On
Site Amara Nasiriyah Najibiyah
Governorate Missan Thi Qar Basrah
Gas Turbines number 4 units x 125 MW 4 units x 125 MW 4 units x 125 MW
Simple Cycle PS In operation Planned, Not started In operation
All three (3) sites utilize four (4) gas turbines of GE make, Frame 9 E type or plan to install.
The power stations at Amara and Najibiyah have been completed and the gas turbines in simple cycle
mode are in commercial operation. At Nasiriyah site, the gas turbines have not been yet installed
however the EPC contractor has been selected and the installation works are expected to commence
in early 2016 and be completed in 25 months from thereafter.
The site of Najibiyah has been ruled out for Add-On because there is no extra land available for
accommodating the equipment needed for the conversion into combined cycle. The sites of Nasiriyah
and Amara have adequate extra land and they have been compared with following terms:

Note: The above site information mentioned in Table-2 has been provided by MOE
The site of Nasiriyah has been selected because of the vicinity of the river water (Euphrates) which
ensures availability of the water to the Power Station, in the required quantity and with lower
pumping costs.
Furthermore the time schedule expected for the implementation of the SCGT power stations in
Nasiriyah site (25 months) allows to put in place all necessary arrangements, such like financing,
proposal and signing of the EPC contract, for starting the Add-On project in timely and smooth
manner. So the Power Station can be phased in 2 consecutive steps: the simple cycle and then its
conversion to combined cycle.
3.2.2 Existing Facilities
Currently the simple cycle power station at Nasiriyah has not been installed yet however four (4) gas
turbines have been already purchased and kept in the warehouse. The EPC contractor for installing
four (4) gas turbines and generators in simple cycle and providing the associated auxiliary systems
has been selected. The EPC works are expected to start in the early months of 2016 and last for a
period of 25 months.
The SCGT Power Station is designed with four (4) GE gas turbines and generators Frame 9E (MS
9001EA), outdoor installation type, having Non Dry Low Nox (Non-DLN) combustors with
capabilities to fire crude oil as main fuel, light distillate oil and natural gas as back-up. The natural
-
3-7
gas, although currently not available, is planned by the Ministry of Oil, Iraq (MOO) to be brought
at site at beginning of year 2018.
The SCGT power station will also have common and auxiliary systems as briefly described here
below:
Fuel facilities include an unloading station for light diesel oil, storage tanks and fuel forwarding
system for both crude oil & light diesel oil. Fuel gas station is also envisaged with all necessary
equipment for conditioning of gas before firing in the gas turbine combustors.
Raw water to the plant is supplied from the Euphrates River. Water treatment and storage facilities
include: pre-treatment of the river water with clarification and sludge removal. Reverse osmosis and
EDI type water treatment plant for demineralized water supply for SCGT consumers and water
injection in gas turbine combustors. Service water, fire water and potable water system also
envisaged for plant usage. Effluents treatment and sewage treatment are installed for treatment of
waste water and plant sewage respectively.
Other mechanical systems considered are compressed air, firefighting system and auxiliary boiler.
Electrical power evacuation is by means of four (4) step-up transformers one each for each gas
turbine, 400 kV and 132 kV gas insulated switchgears (GIS) located indoors. Electrical power
distribution has unit auxiliary transformers (UAT), MV power distribution system, LV power
distribution system, emergency power supply system and emergency diesel generator.
Gas turbines are installed outdoor having their own compartments/enclosures. The SCGT power
station includes central electrical and control building, GIS buildings, administration building, fire
station, canteen, warehouse, bachelor house and workshop building.
3.2.3 Combined Cycle Configuration
The conversion of a SCGT power station to a CCGT power station is realized by adding the HRSG
that utilizes the heat of the exhaust gases for generating steam which is utilized in operating a steam
turbine and generator to generate electricity.
The steam from each HRSG can be connected to four sets of smaller sized steam turbines or the
steam output from each of the four HRSGs can be combined together to supply the steam to a
common piping header which then feeds one larger sized steam turbine. The way the GTG/HRSG
-
3-8
units are grouped in order to supply steam to the steam turbine and the number of steam turbine
determine the configuration of the combined cycle.
In consideration with the following advantages, the 4/4/1x1 configuration mentioned below will be
more recommendable in this feasibility study than the 2/2/1x2 configuration mentioned below.
Advantages of the 4/4/1 configuration:
The bigger capacity STG unit has better efficiency than 2 STG of smaller capacity for the same steam parameters.
Lower capital costs due to saving on the cost of the steam turbine and generator, their foundation and STG building, step up transformer, electrical power distribution equipments
and cabling.
Suitable for base load
The plot area requirement is less (the available site area in Nasiriyah is limited).
Reduced construction area during the construction at site.
4/4/1x1 configuration: 1 block comprising of four (4) gas turbines, four (4) heat recovery
steam generators and one (1) steam turbine generator.
2/2/1x2 configuration: 2 blocks each comprising of two ( 2) gas turbines, two (2) heat recovery
steam generators and one (1) steam turbine generator
As Nasiriyah site will have four (4) GTGs of about 125 MW ISO rating, this report describes
feasibility study of the 4/4/1x1 configuration with the consent of MOE.

3.2.4 Design Basis for the Add-On Project
The design conditions utilised for the Add-On project have been considered as follows:
3.2.4.1 Fuel
Main fuel considered for Add-On project is natural gas while crude oil and light fuel oil are back up
fuels.
This is because the fuel gas is expected to be available at Nasiriyah site in early 2018 and the cost of
the natural gas is expected to be lower than crude oil and light fuel oil. Further as per information
from MOE, the fuel gas is envisaged to be used as main fuel after 2018. Thus the Add-On project will
be starting the commissioning and the commercial operation with fuel gas.

and detailed power system network of PSS/E data of the current 2015 condition. Depending of the
circumstances and from the MOE provided data, the condition of the Power System including that
of 2015, will be organize in this section.
3.1 Areas and Governorates in Iraq
Iraq is divided into 5 areas and 15 governorates (excluding the Kurdistan Region) as shown in
Table 3-1.

3.2 Power Network System in 2015
The PSS/E data of the 2020 Power System provided by MOE had some comment written of the
actual situation. The study team assumed the power system network of 2015 based on this comment.
The power system network in 2015 is shown Figure 3-1.
The power system network of Iraq in 2015 has 30 substations and the total length of 400kV
transmission lines approximately 4,900km.
3.3 Expansion of power system network
Figure 3-2 shows the power system network in 2020. The substation, power plant and transmission
line is particularly enhanced at middle southern area.

3.4 Demand and supply balance in 2020
By analyzing the network data of PSS/E provided by MOE the areal demand and supply balance
has been considered to be as shown in Table 3-2.
The total demand in 2020 is 28,541MW including transmission loss and station service power.
Middle area, of which the capital city is Baghdad, accounts for 35% of total demand, and Southern
area, which has the second largest city of the Country, Basra, accounts for 26%. Hence, Middle and
Southern areas account for about 60% of total demand.
Meanwhile, Middle and South areas have 31% and 25 % of total power generation over the country
29,037MW, respectively. Accordingly, the power is not transmitted between areas. The loss of
power system network on this demand and power generation situation is small.

3.5 Network system in 2020
The 400kV network has performed at the bulk power transmission system among areas and 132kV
network has played the role of local supply systems.
Figure 3-4 shows 400kV bulk power network as of 2020. 400kV transmission line are particularly
enhanced in the north-south direction. Mosul, Baghdad and Basra city is in this straight line.
The Iraqi power system has been interconnected with Iranian power system by a 400kV single
circuit transmission line at Diyala substation located in Upper Euphrates area.
3.6 Transmission line
Table 3-3 shows the 400kV transmission lines in 2020. The total length of 400kV transmission lines
reaches approximately 8,300km. This length is about two times of that of 2015.
The transmission line capacity of 400kV lines has 970MVA, 1000MVA and 2774MVA. According
to the PSS/E data, capacity of 2774MVA line is using a quad conductor. This quad conductor of

3.8 Power Plant
The power plant development plan in Iraq prepared by MOE is shown in Table 3-5 and 3-6. The
study team made location map of the power plant development plan as shown in Figure 3-5 and
Figure 3-6. The total amount of the two plans is approximately 30,000MW of generator capacity.
The current demand planning is about 29,000MW in 2020, it was found to be sufficiently supplying
the demand with the new power plant and the existing power plant.
Construction or reinforcement of the power plant have been conducted mainly in Middle Euphrates
and Southern region.
