Figure 3 Management Scheme
The project will be operated by a personnel of 9 in total. The electricity generation status of the
facility will be remotely monitored by the company in Ulaanbaatar, and if an abnormality isdetected, electricians and other workers stationed in Altai will respond.
Although in many cases large-scale solar power generation are operated as unmanned power
plants in Japan, for 2 reasons, namely the prevention of theft of panels and other equipment, and theneed for regular cleaning of the panels due to the dusty climate, in this project it is planned to haveresident staffs at the power generation plant.
Since operation and maintenance standards for solar power plants is not officially defined in
Mongolia, in this study, Japanese standards have been adopted, as Japan has a broad diffusion oflarge-scale solar power generation plants. The Japanese standards are expected to ensure stable
operation of the power generation plant. The operational know-how of SAISAN Co., Ltd,
accumulated through a large-scale solar power generation business track record of 6 projects inJapan, will be harnessed to achieve stable continuous operation in the project.
(2) Maintenance and Inspection Scheme
For the same reasons above, Japanese standards for maintenance and inspection will be used. The
Japanese safety inspection standard is defined in the “Electricity Business Act second Subsection 2
voluntary safety”. Subsection 2, Article 42 which states that “the power plant’s managementcompany shall establish a safety system and shall notify the Ministry of Economy, Trade andIndustry”, and Article 43 which states that “a licensed electrician will be selected as theadministrator of the power plant”. Complying with these provisions, in addition to developing
safety regulations for the plant, a technician with the equivalent capability of a Japanese domestic

The company which is the main entity of this project consists of SAISAN Co., Ltd and myclimate
Japan Co., Ltd. Operation of the company is planned to be entrusted to Unigas LLC. Details of the
management structure will be further defined in the future.
Although the power generation company to be newly established does not have a track record,
SAISAN Co., Ltd already has experience of operating 6 mega-solar projects in Japan. SAISAN Co.,Ltd currently owns the 6 facilities, and entrusts the maintenance and management tovarious EPC operators. Of the domestic track record, NE, one of the outsourcees in this study, acted
as a subcontractor for the Yorii-machi project in Saitama Prefecture, and is advancing discussions
to participate in maintenance and management of this project.
1.1.5 Financial Analysis(1) Financial Analysis[Prerequisite 1: Determination of Generation Capacity]
Regarding the generation capacity of the project, outsourcees NE and GP respectively proposedfor 10MW and 8MW, whereas both Mongolian University of Science and Technology (MUST) andNational Dispatching Center (NDC) (government entity under jurisdiction of Ministry of Energy incharge of electricity distribution as well as balancing of demand and supply) suggested that
5MW-6MW is the most appropriate capacity.
Determination of generation capacity will be made before investment decision held in March 2015.
In this study report, analysis is made based on generation capacity set initially (10MW).
[Prerequisite 2: Status of Discussion with Ministry of Energy of Mongolia on Details of Power

Investment decision will be made by March 2015, based on a comprehensive evaluation ofanalysis results on 10MW and 5MW capacities above, as well as details of PPA, project risks andcountermeasures (including adoption of insurances).
(2) Financing Method
3 financing methods are planned for this project - first method being utilization of JCM financing
scheme, second being capital stock of the power generation company (joint venture of SAISAN Co.,Ltd and myclimate Japan Co., Ltd), and third being loan from Japanese banks.
First candidate for loan from Japanese banks is JBIC. Discussions have been made with the bankand as a result, under the condition that the project is sure to be selected as recipient of JCM
financing program, provision of corporate finance is possible (repayment period is approximately
7-10 years). Interest rate is set by JBIC based on 6-month London Interbank Offered Rate (LIBOR)
and grade of lender. As of currently, the interest rate is assumed to be 0.8%. However, since themaximum amount of loan from JBIC is limited to 70% of total amount of loan, the rest of theamount is to be obtained from private banks with business connections with SAISAN Co., Ltd andmyclimate Japan Co., Ltd. The interest rate for private banks are assumed to be 1.2%. The project
participants will proceed with negotiation with JBIC and private banks to prepare for financing of
the project.
(3) Risk Assessment
4 types of risks are identified in this project and respective countermeasures are taken into
consideration.
1. Country Risk and Countermeasure
Risk of discontinuation of the project due to country-specific issues such as political instability
and natural disasters is considered. Countermeasure for this risk is to enroll in trade insurancewith JCM Special Financing Scheme by Nippon Export and Investment Insurance (NEXI),
which is applicable up to 100% of total loss caused by this risk. For this project, NEXI has
confirmed that it is acceptable to adopt trade insurance to deal with this risk.
2. Default Risk and Countermeasure
Risk of discontinuation of the project due to inability of PPA counterpart to fulfill thecontractual obligations is considered. Similar to Country Risk, countermeasure for this risk is toenroll in trade insurance by NEXI. Since the applicability of trade insurance differs for every
project, the project participants will continue negotiating with NEXI in order to utilize theinsurance.
3. Exchange Risk and Countermeasure
In Mongolia, business transactions are required to be made in MNT (Mongolian Tugriks). For
this project, risk of exchange losses during income transaction from power generation company
in Mongolia to Japan in the case of denomination of electricity price in MNT is considered.
Countermeasure for this risk is to determine electricity price monthly, based on latest exchange
rate of USD/MNT available.
4. Contractual Risk and Countermeasure
Risk of amendments in the PPA due to change of government and amendments on related laws
is considered. Countermeasure to this risk is to ensure the contents of PPA continue in effectregardless of the circumstances in the country by signing of Stability Agreement. The Ministryof Energy has agreed to sign the Stability Agreement and currently the contents of theagreement are being discussed.

3) Advantages of Japanese Technology
2 studies were carried out as part of this survey. (1) To select the solar panels, being the major
device of the project, and the inverters, and to try to clarify the functional superiority of Japanesetechnology; (2) to clarify other elements required for large-scale solar power generation projects,
and to attempt to verify the superiority of Japanese technology in this field.
(1) Regarding the superiority of Japanese technology of the selected solar panels and inverters
The following equipment are planned to be used in the project.
Solar panels:
Next Energy and Resources Co., Ltd. (Japan), output 255W, conversion efficiency 15.5%
Inverter:Company A (Japan), output 630kW, conversion efficiency 98.6%
These products were compared with those of China, Germany and Switzerland and the results ofthe comparison show that the Japanese products both have performance that can be said to be “topclass”, but it has been confirmed that there is no appreciable difference when compared to foreign
products. This is due to the global progress of solar power technology development, and reflects thecurrent state of performance, whereby both the difference in price and functionality between
countries has been lost.
(2) Regarding the superiority of Japanese technology in other elements that are required forlarge-scale solar power generation businessTo generate electricity over a long period for more than 20 years consistently, in order to ensureprofitability, in addition to the individual performance of equipment, the following 3 elements wereidentified.
a. To continue to maintain the devices that perform power generation over a long period of time,
and the structure of the warranty system (Structure of the warranty system)b. Also for long-term operation and to avoid unexpected failures, optimal design and construction
suited to local environmental conditions (optimization of design and construction)c. For prolonged, stable power generation, suitable structure for monitoring, operation andmaintenance (maintenance and operation structure)

JCM Project Planning Study (PS) 2014 – Final Report

With the spread of the solar power generation business, EPC operators offer a comprehensive
service to provide the three elements of design, equipment procurement, and construction. NE
expects it is the case that Japan domestic EPC operators use their achievements in Japan as thefoothold for increasingly looking towards overseas expansion. And the trend in Japan and otheradvanced PV countries is that these EPC operators offer the equipment manufacturer's warranty,
and their own EPC warranty, or a warranty system offered in cooperation with an insurancecompany, and use the optimal design construction technology which they have developed throughindependent research, as a weapon to implement optimized design and construction, andfurthermore add monitoring and control systems as part of a comprehensive package.
It is difficult to compare the technological superiority of such integrated services, but it is
becoming a requirement of eligibility that EPC operators have systems for warranty andmaintenance. By doing this, through the utilization of JCM schemes, the experience gained in Japan
can be used as a weapon to boost overseas expansion of Japanese domestic EPC businesses, and it
is expected that these Japanese technologies propagate.
4) MRV Structure(1) Draft of MRV Scheme
From the 2 points of view of securing accurate data, and the maintenance of normal operation of
the facility, the monitoring and reporting scheme shown in Figure 2 is proposed.
Project Manager (1 person, stationed at Ulanbaatar),
Deputy Project Manager (2 persons, stationed at Ulanbaatar)

Electrician (1 person, stationed at Altai City)・ Double check on monitored data

Operator (2 persons, stationed at Altai City)・ Accumulation and recording ofmonitored data

Figure 4 Monitoring and reporting scheme of the project(2) Training Session for Establishment of MRV Scheme
To ensure the accuracy of monitoring data and maintain normal operation of the project, it isnecessary for the main entity to acquire knowledge on monitoring. In addition, since this project is
intended to reduce GHG emissions by connecting to the grid, coordination with the Ministry ofEnergy which has jurisdiction over power generation business, as well as relevant licensing
agencies, is essential. In order to continuously and stably reduce GHG throughout the lifetime of the
project, it is extremely important to deepen the understanding of large-scale solar power generation
among Mongolian government officials.
Therefore in this study, the "10MW-scale Solar Power Generation Project Steering Committee"
comprising the main entity and Mongolian government officials has been established, anddiscussions aimed at project implementation, sharing of knowledge, monitoring system and thestructure of cooperation with the Mongolian government have been held. In particular, the 2ndcommittee meeting was held in late January 2015 to focus on establishment of the
MRV scheme. The main contents of the 2nd committee meeting are as follows.

9JCM Project Planning Study (PS) 2014 – Final Report■ Visit to solar power generation plant at Yorii, Saitama Prefecture) (held on 20 January 2015)
Through the facility tour, in addition to introducing mega-solar technology of Japan to the
Mongolian side, training on facility management methods (monitoring of system, maintenance, etc.)
were also carried out.
■ Visit to TEPCO (held on 22 January 2015)
The point of view from Japanese domestic power operators was introduced, such as the mechanismof balancing supply and demand when renewable energy sources are installed and details of PPA.
■ Visit to Agency for Natural Resources and Energy (held on 22 January 2015)
The propagation of renewable energy in Japan, circumstances that led to the spread of renewables inJapan, and the mechanism used (feed-in tariffs, renewable energy levy, etc.) were introduced.
(3) Selection of Measuring Equipment
For monitoring the amount of electricity sold and purchased by the project, a watt-hour meter will
be used. The type of watt-hour meter used in Mongolia is specified by the Mongolian Agency forStandardization and Methodology (MASM) which has jurisdiction over standards and registrationof measuring instruments in Mongolia, and is defined in MNS5660: 2006 (Alternating Current
Static Watt-hour Meters for Active Energy). NE who is responsible for the selection of watt-hourmeter confirmed that the watt-hour meter planned to be used in this project meets the criteria set by
the Mongolian standard.
5) Environmental integrity and Sustainable development in host country
1.5.1 Securing Environmental Integrity, Impacts (Positive and Negative) on the Environmentby the Project and Countermeasures
Impacts of the project on the environment is described below.
[Positive Impacts on the Environment] Reduction of GHG
Realization of this project will contribute to reducing GHG emissions of Mongolia, which has seen
rapid economic growth and associated growing energy demand. This project is a beginning, andfurther GHG reduction is expected as renewable energy power generation projects in Mongolia
become more widespread.
 Mitigation of Air Pollution
Increasing the power generation rate from renewable energy by the realization of this project,makes a break from dependency on coal-fired power generation, contributing to air pollution
reduction in Mongolia. If this project creates an opportunity for renewable energy power generation
to further increase as an alternative to fossil fuels in the energy sector of Mongolia, and leads toefficiency improvements and further promotion of renewable energy, this will lead to further
prevention of air pollution.
[Negative Impacts on the Environment] Impact on Residents due to Reflection of the Sun
An environmental impact assessment (general evaluation) was carried out on the implementation of
the present project site, and no adverse effects of this project were found. The project site is locatedin a remote location 4.7km from Altai city, there are no residences or facilities other than an airport
in the vicinity. With implementation of the solar power generation business in the vicinity of the
airport there is a possibility that it might affect aviation, but the view of the Altai Prefecture landdevelopment director was sought, and it was confirmed that there is no problem.

JCM Project Planning Study (PS) 2014 – Final Report

1.5.2 Contribution to Sustainable Development
Contribution of the project to sustainable development is summarized as below.
[Contribution in Social Aspects]
 Realization of Stable Electricity Supply
If the recent trend continues where supply is limited due to the growing power demand due toeconomic growth, it could adversely affect economic development. However, for Mongolia, which
relies on coal for most of its power, if further expansion is based on coal-fired power plants, it is noteasy considering the cost and the time required, and furthermore considering the serious problem of
air pollution, alternative sources of power in place of coal-fired power are needed. Despite the factthat Mongolia is suitable for large-scale solar power generation with its high level of solar
irradiation and vast land, no large-scale solar plants of more than 1MW have been grid-connected at
the present time. Through our research we found that although solar power plants have beenplanned, due to the absence of investors none have been realized. If, through the realization of thisproject, large-scale solar power plants can spread in Mongolia, providing a stable supply of power
for the country's economy, the social contribution is large.
[Contribution in Economic and Technical Aspects]
 Promotion of Renewable Energy
Once this project has been realized, it is an opportunity to spread other solar power generation
businesses rapidly. In that case, construction materials starting with solar panels and businesses
such as design and construction may be promoted.
 Industrial Development of Gobi-Altai Aimag
In the Gobi-Altai aimag, in addition to insufficient power supply to meet the existing demand, there
is also no clear path to proving the power that will be needed for future developments starting withmine developments that are currently being promoted in the prefecture. The realization of thisproject will enable sufficient power supply for the existing demand, and by promoting the spread oflarge-scale solar power generation businesses in the region in the wake of this project, power for
future demand is ensured, bringing great effect for the industrial development of the region.
 Transfer of Japanese Technology
As mentioned above, if the renewable energy industry is promoted in Mongolia, there is apossibility for entrance by Japanese companies in this field. If Japanese companies continue to enter
into the Mongolian market, local transfer of superior Japanese technology, can lead to further
development of the country's renewable energy technology.
6) Toward project realization (planned schedule and possible obstacles to be overcome)1.6.1 Project Realization Schedule
The schedule towards project realization is as follows. Approval of the Feasibility Study report tobe submitted to the Ministry of Energy by the end of this March, and complete the agreement
and MoU for the sale of electricity through consultation with the Mongolian government officials.

The methodology that applies to this project is introducing new photovoltaic systems or adding a
new unit to an existing solar power system to generate renewable energy to supply to the grid,achieving emission reductions. Therefore, emissions reduction are calculated by multiplying theamount of renewable energy to be generated by the project (EGREF,p) by the emission factor of thegrid power to be replaced (EFCO2,grid,p).

(2) Calculation of Project Emissions
In this project, air conditioning of the building, ancillary power consumption by the power control
unit (inverter and solar radiation meter, etc.) occur. The project site is located in a remote location,
since there is no nearby independent power generation equipment, this power will be imported fromthe grid (purchases). Therefore, this power consumption will be monitored and multiplied by theemission factor of the grid power, and this amount will be subtracted as project emissions.

Based on the above calculation formula, the annual emission reductions of the project wascalculated as follows.
(Reference emissions)
RE p  EG RF , p  EFCO2, grid, p= 15,579,405 (kWh / year) × 0.817 (t- CO 2 / MWh)
= 12,728,37 ≒ 12,728 (t- CO 2 / year)/ 1000 (kWh)(Project emissions)

= 51,996 (kWh / year) × 0.817 (t- CO 2 / MWh) / 1000 (kWh)= 42.48 ≒ 43 (t- CO 2 / year)(Emission reductions)
ER P = RE P - PE P
= 12,728 (t CO 2 / year ) - 43 (t CO 2 / year )= 12,685 (t CO 2 / year )Annual emission reductions of the project are calculated as 12,685 (t CO 2 / year).
3) Data and parameters fixed ex ante
The ex ante parameter before project implementation used in this methodology is the grid emission
factor calculated in the next chapter of 0.817tCO2/MWh. The calculation method is shown below.
2.3.1 Understanding the Interconnectivity of the Mongolian Grid
There are 4 electrical grids in Mongolia - Central Energy System (CES), Western Energy System(WES), Altai-Uliastai Energy System (AuES) and Eastern Energy System (EES). Of these, it has
been confirmed by this study that the WES and AuES, and the AuES and CES are interconnected.
Currently, the CES comprises more than 80% of the transmission amount of the entire Mongolian
power system, while the WES and AuES are overwhelmingly small as compared to the CES1.

JCM Project Planning Study (PS) 2014 – Final ReportFeatures of the CES
The CES is composed mainly of sub-critical coal-fired power plants. Specifically, there are fivethermal power plants: the second thermal power (21.5MW), third thermal power (136MW), fourth
thermal power (580MW), Darkhan CHP (48MW), and Erdenet CHP (28.8MW). Also, in the CES,
in order to meet the increased power demand in the region that it powers, plans to build a new
subcritical coal-fired power station of 450MW in 2017 (5th thermal) are underway.
Features of the WES
The main power of the WES is provided by a single hydroelectric power plant of 12MW, which
was built as a CDM project. To compensate for the chronic power shortage, power is imported from
Russia.
Features of the AuES
The main power of the AuES is a hydroelectric power plant of 11MW, which was built as a CDM
project. In addition, imports from the WES and 2 diesel power generators (8.5MW and 7.0MW)
have been providing the power demand. From 2013, especially for dealing with seasonal power
shortages in winter, imports started from the CES, accounting for 45% of the total amount oftransmitted power of 2013 on the AuES.
From the current state as mentioned above, if the CES, WES and AuES are considered as one grid,
nearly 90% of power generation are composed of coal-fired power. In addition, in view of the newplan for thermal power generation in the future of the CES, during the implementation period of
JCM until 2020, the status occupied by coal-fired power is not expected to greatly change.
2.3.2 Setting of Target Range of Emission Factor
In the setting of the emissions factor in this methodology, the CES, AuES and WES are regarded
as one grid. Power that will be most affected by the implementation of this project, is considered tobe coal-fired power generation facilities in the CES. Thus, it was decided to take the approach of
setting the grid emission factor in this methodology on the basis of the emission factor of theexisting coal-fired power generation.
2.3.3 Setting of Emission Factor
In determining the grid emission factor, in order to ensure that the net emission reduction isachieved by the project to which the methodology is applied, a calculation process that estimates
lower than the actual emissions reduction in the emission reductions methodology was
examined. The procedure is described below.
①Determination of Thermal Efficiency of Coal-fired Power Generation Affected by the Project
The existing thermal power plants of Mongolia are all sub-critical pressure power generation
plants. Of the 5 plants connected to the CES, figures showing that the lowest thermal efficiency is
21.2%, and the highest is 40.5% have been published.

The thermal plant due to be commissioned in 2017 will also be a sub-critical. In the calculation ofemission factors, by adopting the thermal efficiency of the latest supercritical pressure power orultra-supercritical pressure power plant, it is possible to realize the calculation of a moreconservative reference emissions figure. This methodology employs figures published by the
Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan"Commercialization of State-of-the-art Power Generation Technology and Development Status(BAT reference table 2)", giving the design thermal efficiency of power generation at generation
point of 44.5% as the thermal efficiency of power generation.

To confirm that the calculated emissions factor compared to the actual emissions factor of the CES
is a conservative estimate, the latest value of the grid emission factor applied for CDM projects
connected to the CES was compared. This value has been calculated by the Institute for Global
Environmental Strategies (IGES) and has been published 3 . Both Operating Margin and Build
Margin are above 1.0tCO2 / MWh, confirming that the figure of 0.817kgCO2 / kWh used in themethodology is a conservative reference emission figure.

In this methodology, the emissions factor of 0.817tCO2 / MWh, calculated above, is assumed toapply until 2020. In the case that this project continues after 2020, either through JCM or a similar
emissions reduction scheme to be agreed, at that time, a review of the emissions factor should be
carried out, and re-confirmation that it is a conservative figure is recommended.

There will be temporary noise and vibration generated by the assemblyof the solar panels, but this will not be a significant impact on thesurrounding environment.
Since there are no rivers near the site, prediction and assessment of the
impact on rivers has not been performed.
Water pollution due to hazardous substance leaks during theconstruction period may occur.
This project does not have direct impact on the groundwater. However,if there is leakage of hazardous materials during the construction
period, there is a possibility that ground water pollution occurs.
There is a possibility of water contamination due to improper
processing of wastewater.
During the construction period there is the possibility of soil erosion
by vehicles.
During the construction period there is a possibility of soil
contamination by hazardous substances leakage.
During the construction period temporary disruption of vegetation will
occur.
Dust caused by the comings and goings construction vehicles might
affect the ecology of the plants.
This project implementation might affect animal life.
During the construction period due to a temporary increase inpopulation, illegal hunting may occur.
Not Applicable (there are no protected areas in the vicinity of the
project site).
Since no cultural properties exist near the site, prediction andassessment of the impact of the cultural properties has not been
performed.
Employment creation through implementation of this project can be
expected.

As can be seen in Table 3-1, the environmental impact expected at the present consists of normal
effects that can occur during construction work, and there are no special environmental impacts ofthe project. At 4.7km from the city, with no housing or nature reserves in the vicinity, it has been
judged that there are no special impacts on the surrounding environment due to the implementationof this project. We have obtained comments that cases where a detailed environmental impact
assessment evaluation is required by the Ministry of Environment and Green Development for solar
power projects are rare, and further environmental impact assessment work is not expected to occur.

or more. Therefore, there is no fear of adverse impact on the airport.

In general, local residents living close to the site have high potential impact from the project
implementation and typically require consultation the project implementation, however ① at thissite there are no houses around and the site is away from any residential area, ② explanation havebeen made to residents of the area ③ it has been confirmed that there is no problematical effect on
the airport due by the Land Development Bureau, therefore consultation and coordination have been
judged to be unnecessary.

4) Calibration of Measuring Instrument
Although a power meter will be used in this project, Mongolia national standards MNS5660:
2006 (Alternating Current Static Watt-hour Meters for Active Energy) does not describe clear
standards for calibration of the power meter. Therefore, in this project, the period of calibration will
be based on the standards of Japan. According to the provisions of the Ministry of Economy, Tradeand Industry in Japan, there are different validity periods of calibration depending on the type ofenergy meter, and it is necessary to use the equipment within that period 5 (Table 3-3 ). This projectwill use a 35 kV, 200 ~ 300A meter connected to the transmission line, therefore the validity periodof the power meter is set to 10 years.
