SECTION A. Description of project activity

A.1. Purpose and general description of project activity

The Cam Lam VN Solar Power Plant is necessary to supplement the power supply, as the demand
for electricity will gradually increase due to continuous development country wise and at province
level. The power will contribute to reduce environmental pollution by providing clean energy
sources in line with the general sustainable development trend of the world. The project use poly-
Mono-Si photovoltaic cells without any backup generators and will generate 100% clean energy to
be fed into the national grid.

The 50 MW project is installation of a new power plant at the site and is not a capacity addition or
retrofit or replacement of any other existing plant. So the current baseline scenario is the energy
that is being fed into the national grid through other power plants, the details of which would be
provided in the document later, and the project scenario is a clean Greenfield power plant that
would generate energy and supply it to the national grid. This energy would help reduce the energy
deficit of the country by supplying the electricity through the grid.

The project would be generating around 78,885 MWh of electricity on average for the first crediting
period as per the data from the contractor and would thus be reducing 66,991 tonnes of CO2 from
the atmosphere annually, thus generating 66,991 CERs for the relevant crediting period. As the
minimum power generation requirement that the power purchaser requested is 78,885MWh and
the minimum power generation requirement can be achieved at a performance Ratio 79.84%, the
average electricity generation from this project is capable to meet the requirement during the
crediting period.

The most significant improvement the project would be making the generation of electricity itself
that would reduce the load shedding and the energy crisis to some extent and provide electricity to
the local population. The entire solar park in the long run would play a critical role in attempting to
bridge the supply demand gap that the country is facing at the moment.

A.2. Location of project activity

Khanh Hoa is a coastal province in the south of Vietnam, some of its territory extend farthest to the
South China Sea.

• Host Country: Viet Nam

• Region/State/Province etc.: Khanh Hoa Province

• Town/City/community etc.: Cam Nghia Ward, Cam Ranh City
• Geographical coordinates: 11°59`29.6322" N, 109°5`8.31" E
The project area had been used for annual crops production but it does not bring high productivity
and inefficient to develop agriculture and forestry. At the same time, this position is not in the
planning of other projects and there are no inhabitants. Therefore, priority should be given to the
development of solar power plants in these areas to maximize land use efficiency.

There are natural advantages along with easy grid connection, roads and status, and favorable
land use planning are important factors for the project to be feasible and gain high efficiency.

A.3. Technologies/measures
Solar PV system use directly sunlight for electricity production tank to solar module systems. Solar
modules are made of many different types of materials, manufactured by many processes and
used widely for solar power projects in the world. Solar PV systems may only create electricity on
day and power output will also vary according to different conditions of weather. However, Solar
PV systems will produce max electricity on days hot days, where the needs for electricity is
increasingly high.

Figure 2 Typical grid-connected Solar Power Project

Solar PV modules will invert sunlight into DC current by photovoltaic effects. This energy will be
converted into AC with the same frequency of the grid’s current through frequency inverters.
Multiple solar modules are connected, which can range from tens of watts (W) to tens of
megawatts (MW). For solar panels manufactured for commercial purposes, the photovoltaic
conversion efficiency of solar panels ranges from 14% to 20%. This technology mainly uses tow
radiation components that are direct and diffused and suitable even in area with low direct radiation.

When designing the Cam Lam VN Solar Power Plant which has total capacity of 50 MW arranged
with a layout area of about 60ha, the PP consider the following issues and select the main
equipment.

Fixed flat PV module

PV modules will be fixed in a certain direction. This configuration will make the installation simple,
and make installation and maintenance cost very low. The PV modules will be installed in a fixed
direction so that PV modules receive solar radiation energy the most.

Solar panels
According to the operation license of the Cam Lam VN Solar Power Plant, PP uses a 144cell,
Mono-Si with a capacity of 385Wp and 390Wp module.
According to Decision 11/QD-TTg of the Prime Minister on the mechanism for supporting the
development of solar power, the efficiency of PV panels should be > 15%.

Inverter
With the development of inverter technology, for large-scale grid connected solar power plants,
solutions using inverter power units with a capacity of, more than 500 KVA/inverter are suitable.

In the current phase, for large-scale grid connected solar power plants such as Cam Lam VN Solar
Power Plant, the solution is to use central inverter units with a capacity of 1000KVA/inverter or
more and use a suitable common configuration.

Annual power output estimation is expressed with a range of values with certain reliability. P50
value is the estimation of the potential annual power output. The uncertainty of energy yield
simulation software depends on each modelling stage and on the uncertainty in the input variables.
Modelling software itself can introduce uncertainty of 2 percent to 3 percent. Uncertainty in other
modelling inputs include estimates in downtime, estimates in soiling, uncertainty in the inter-annual
variation in solar resource and errors due to module specification not accurately defiling the actual
module characteristics.

Plant Monitoring
Large capacity inverter is built in communication modules and internal protocol processing. Input
parameters (DC side) and output parameters(AC side) will measure and collect data such as
current, voltage, power, frequency of solar module groups. Grid connection data, on-site status of
the plant and real-time response data will be collected with 1 main meter with 0.2s class accuracy
and 2 back-up meters with 0.5s class accuracy.

The plant does not have any emission sources and GHGs within the project boundary that may
need any monitoring. The plant boundary in the diagram is shown via a dotted line whereas, the
project is connected to the national grid. The project boundary, thus, is depicted by solid line.

B.4. Establishment and description of baseline scenario

According to ACM0002 version 19.0, in case of the baseline scenario for the Greenfield power
plant, the baseline scenario is electricity delivered to the grid by the project activity would have
otherwise been generated by the operation of grid-connected power plants and by the addition of
new generation sources, as reflected in the combined margin (CM) calculations described in
“TOOL07: Tool to calculate the emission factor for an electricity system”. (Versions 7.0)

The Project activity is generation of electricity from renewable energy sources. The electricity
generated from the solar PV plant has zero emissions; there is no material leakage and the
electricity generated will be fed into the fossil intensive national grid through the interconnection
facility at the site.

The grid in Viet Nam is partly composed of greenhouse gas intensive fossil fuel based power
stations. The state-owned company Electricity of Viet Nam (EVN) dominates power production,
transmission, and sales in Viet Nam. Vietnam has a large range of domestic primary energy
sources such as crude oil, coal, natural gas and hydro power which have played an important role
in ensuring energy security for economic development in the past two decades. With the increasing
energy demand and recent fluctuations in energy import and export, Vietnam has become a net
energy importer since 2015.

All power plants in Viet Nam are physically connected to the Viet Nam national electricity grid,
which is operated and monopolized by the EVN. Thus, the baseline scenario of the proposed
project is the delivery of equivalent amount of annual power output from the Viet Nam national grid
to which the proposed project is also connected. The database for calculating the baseline is
published by the DNA of Viet Nam.

One of the key assumptions made in determining the baseline is to treat the whole grid system as
one entity. The grid system is not divided into provincial sub-groups (as in China for example). The
only distinction made by the EVN as to categorize power stations are by power source (hydro
power 37.6%, Coal fired power 34.3%, Gas fired 17.3%, Oil fired 3.3% others included diesel,

Version 11.0 Page 8 of 26

 CDM-PDD-FORM
small hydro, renewables 5.8%, import 1.2%) and ownership (state, independent power producer,
“build-operate-transfer”).2

According to the official letter No.330 BDKH-GNPT published by DNA Vietnam on 29/03/2019, the
operating margin emission factor EFgrid,OM,y = 0.8336 tCO2/MWh; and the build margin emission
factor EFgrid,BM,y = 0.8961 tCO2/MWh which is not changed during monitoring period according to
the TOOL 07 para 72&73, Option 1. And based on “Tool to calculate emission factor for an
electricity system”, the defaults weights value for solar power projects.

A conservative approach was taken by using the approved ACM0002 methodology, which states
that the Project activity would replace the weighted average of the ratio of emissions in the system
represented by:

(a) The Operating Margin (OM): the ratio of emissions from generation of all power generating
projects in the defined system over the latest three year period excluding least cost/must run
projects; and

(b) The Build Margin (BM): the generation-weighted average emission factor (tCO2/MWh) of all
power units m during the most recent year y for which power generation data is available,
calculated;

(C) The Combined Margin (CM): the default values established in the “Tool to calculate the
emission factor for an electricity system” version 07 for the weighting of the OM (wOM = 75%)
and for the weighting of the BM (wBM =25%)

The value are used in the calculation of the baseline emission factor respectively for Wind and
solar power generation project activities, for the first crediting period and for subsequent crediting
periods; The values for wOM + wBM applied by project participants should be fixed for a crediting
period and may be revised at the renewal of the crediting period.

Accordingly, it is proposed to present in this PDD the measurement of emissions observed when
comparing the “business as usual” case (without the project activity) with emissions under the
project (the “project scenario” case). The baseline emission factor represents a conservative
estimate of emissions per MWh of grid generation and the emissions “saved” per MWh of the
project generation.

Vietnam’s average electricity grid emission factor of 0.8492tCO2eq/MWh, as stipulated by the

Government of Vietnam (Ministry of Natural Resources and Environment Vietnam) in March 2019
and the carbon dioxide intensity of the fuel source (other than electricity) used in the relevant
industrial installations.

simplified procedures does not affect the projects that request registration as a CDM project
activity or a programme of activities by 30 August 2020 and apply the simplified procedures
contained in version 19.0 of ACM0002.

B.6. Estimation of emission reductions

B.6.1. Explanation of methodological choices

Baseline emissions include only CO2 emissions from electricity generation in fossil fuel fired power
plants that are displaced due to the project activity. The methodology assumes that all project
electricity generation above baseline levels would have been generated by existing grid-connected
power plants and the addition of new grid-connected power plants. The baseline emissions are to
be calculated as follows:

Equation (1)

Where:
= Baseline emissions in year y (t CO2/yr)
= Quantity of net electricity generation that is produced and fed into
the grid as a result of the implementation of the CDM project
activity in year y (MWh/yr)
= Combined margin CO2 emission factor for grid connected power
generation in year y calculated using the latest version of
“TOOL07: Tool to calculate the emission factor for an electricity
system” (t CO2/MWh)

If the project activity is the installation of a Greenfield power plant, then:

Equation (2)

Where:
= Quantity of net electricity generation that is produced and fed into
the grid as a result of the implementation of the CDM project
activity in year y (MWh/yr)
= Quantity of net electricity generation supplied by the project
plant/unit to the grid in year y (MWh/yr)

Leakage
No leakage emissions are considered. The emissions potentially arising due to activities such as
power plant construction and upstream emissions from fossil fuel use (e.g. extraction, processing,
transport etc.) are neglected.

Emission Reductions
As per the methodology, “ACM0002 Version 19.0”, emission reductions are calculated as follows:

Equation (3)

Where:
= Emission reductions in year y (t CO2e/yr)
= Baseline emissions in year y (t CO2/yr)
= Project emissions in year y (t CO2e/yr)

Project Emissions
The project emissions have been taken to be 0 as mentioned in section B.6.1.

Leakage
Leakage emissions are not considered and neglected as stated in section B.6.1.

Emission Reductions
As mentioned in section B.6.1, the emission reductions from a project can be calculated using the
following formula:

Where:
= Emission reductions in year y (t CO2e/yr)

= Baseline emissions in year y (t CO2/yr)

= Project emissions in year y (t CO2e/yr)

Therefore, Emission reduction

SECTION D. Environmental impacts

D.1. Analysis of environmental impacts

Solar power plants that use renewable energy. It is safe, clean and environmentally friendly power
plants. The operation of a solar power plant does not generate greenhouse gases, so it affects not
only the regional climate but also the ecosystem of the earth. However, during the preparation and
construction of the project, it also has some impact on the surrounding environment.

The project "Cam Lam VN solar power plant" is located in Cam An Bac commune, CAM LAM
district, Khanh Hoa province. Considering the hydrographic climate, especially the region's
radiation potential, the good regional environmental factors are well suited for photovoltaic
development. At the same time, the nature of the terrain and geology of the area is relatively stable,
mainly of sugarcane, acacia, banana, and cashew. There are no treasures, military zones or
industrial projects, chemical works, cultural belief works in the project area so it is very convenient
for the construction of the project. The project area is close to the inter-village road asphalted,
which is very advantageous in transporting equipment to build the plant. The line is built mainly on
sugarcane and cash crops of the people, mainly affecting the production activities of the people
during the construction phase.

D.2. Environmental impact assessment

Evaluation of impacts of land acquisition
The objective of the project is to minimize the encroachment on residential land and historical and
cultural relics such as communal houses, temples and shrines. The project survey area is mostly
uncultivated land and a part of cash crops. During the implementation of the project, about 70ha of
land is for the solar power plant.

Version 11.0 Page 18 of 26

 CDM-PDD-FORM
The destruction of production forests, trees, and crops discourage people's income from
agricultural production, affecting the quality of life of people, making it difficult for people to find a
job appropriate to the level. As a result, these impacts will be mitigated by the attention of the
community and authorities, which will provide adequate compensation for loss of land.

- Negative impact
Loss of all cultivated land has been recovered, loss of income due to cultivation, overcapacity, etc.
However, impacts are only local with households losing their cultivated land. Owners will have
policies to compensate land, crops in accordance with the regulations.

- Positive impact
When the project goes into operation, economic benefits to the project area in particular and
CAM LAM district in general. The project does not have a major impact on ecosystems,
biodiversity; environmental problems such as erosion, sliding, collapse, land subsidence; Climate
Change; degradation of environmental components and other factors. The Cam Lam VN Solar
Power Plant is necessary to supplement the power supply for the demand of load development
continuously of the country in general and Khanh Hoa province, contributing to reduce
environmental pollution, to develop clean energy sources in line with the general sustainable
development trend of the world. Apart from the environmental attributes, this project will bring
about local employment in construction, quality assurance and general management area and
local economy vitalization will thus be expected. Moreover, if we take power demand forecast of
Khanh Hoa Province into account, average commercial electricity growth rate of 10.9%/year is
quite large, so the commissioning of solar power plants to operate in upcoming period seems
reasonable.

Evaluation of impacts of site clearance

During preparation, site clearance, CTRs are mainly demolition materials, photoluminescence of
plant biomass in the project area. The type of waste discharged from demolition,
photoluminescence depends on the volume and characteristics of objects in the demolition area.
In the plant construction area, there are only plant and vegetation. As a result, large amounts of
solid wastes are the branches, leaves and vegetation. The amount of dust diffused due to the
demolition process, clearance of the project is mostly deposited dust, the ability to spread not far.
Moreover, this amount of dust can be controlled by humidification method during demolition
works, land clearance. The concentration of pollutants in the exhaust gases and dust generated
by vehicles transporting wastes during the preparation of construction sites are many times lower
than the permissible standards, so the range and the degree of impact of the polluting sources on
the waste transport route during the preparation phase is negligible.

Impacts on landscape architecture

The PV modules and the entire solar power plant are the typical projects of the clean energy
sector in Vietnam, the project is designed with scientific space and layout. The solar project is a
clean and environmentally friendly energy project that will create beautiful scenery and can
promote the strengths of local sightseeing, learning, research and tourism.

Impacts due to dust generation, emission

In comparison of the use of solar energy to fossil-fuel power projects (such as thermal power
plants, gas power plants, etc.), Cam Lam VN solar power plant project producing electricity from
clean energy does not generate waste, dust, toxic gases, especially greenhouse gases that do
not emit greenhouse gases. With this advantage, the projects of solar power in general, the
project of Cam Lam VN solar power plant in particular is considered a form of "clean energy" or
also known as "green energy", contributing to saving fossil fuel. With a capacity of 50MW, the
Cam Lam VN Solar Power Plant project brings many benefits to localities in particular and to
Khanh Hoa province in general.
