1. Introduction
Thailand Power Development Plan 2007 2021 (PDP 2007) was formulated by
the Electricity Generating Authority of Thailand (EGAT) under the policy framework of the
Ministry of Energy, in terms of reliability of power supply, fuel diversification, power
purchase from neighboring countries, and power demand forecast, etc. The PDP 2007 was
approved by the National Energy Policy Council (NEPC) and endorsed by the cabinet in June
2007. The PDP 2007 has been used as a framework for the development of EGATs new
power plants, the solicitation of new independent power producers (IPPs), small power
producers (SPPs), and power purchase from neighboring countries.
After the approval of PDP 2007, the solicitation of new IPPs and SPPs (both co-
generation and renewable power plants) was undertaken by the Energy Planning and Policy
Office (EPPO) of the Ministry of Energy. The selection of IPPs and SPPs was finalized in
December 2007.
For the processes to purchase power from neighboring countries, EGAT has
reached the agreements for power purchase from several IPP projects in Lao PDR. The PowerPurchase Agreements (PPA) of Nam Ngum 2 (597 MW) and Theun Hinboun Expansion
Project (210 MW), the Memorandum of Understanding on Tariff Setting (Tariff MOU) of
Nam Ngum 3, (440 MW) Nam Theun 1 (523 MW), Nam Ngiep (261 MW), Nam Ou (1,043
MW), and Hong Sa (1,473 MW) projects were signed between EGAT and respective project
developers.
To cope with the present information on committed IPPs and SPPs projects under
the new solicitation, the progress of power purchase from neighboring countries and the
adjustment on the electricity demand forecast, EGAT under the guidance of Ministry of
Energy has reviewed the PDP 2007. The revised PDP called Thailand Power Development
Plan 2007-2021: PDP 2007 Revision 1 was presented to the National Energy Policy
Committee (NEPC) for endorsement on December 7, 2007.

2. Summary
2.1 Current Status
The peak power demand of 2007 occurred on April 24, 2007 of which the
maximum power generation of the country has reached 22,586.1 MW. The growth of
power demand is 1,552.1 MW or 7.22% over the record of 2006. On the view of energy
consumption, the energy demand of 2007, estimated by the record of first eleventh months
(January-November 2007), was 134,873.8 GWh. The increase of energy consumption of
2007 compared to 2006 was 3,987.2 GWh or 3.05%.
2.1.1 Power Plants
As of November 2007, the total installed capacity is 28,530.3 MW,
comprising 15,793.6 MW (55.4%) from EGATs power plants, 12,097 MW (42.4%) from
private power producers (IPPs and SPPs) and 640 MW (2.2%) from foreign power
purchase. The details of installed capacity of Thailand power system are shown in
Appendix 3.
2.1.2 Transmission Systems
The standard voltage levels of EGAT transmission systems are 500 kV,
230 kV, 132 kV, 115 kV, and 69 kV at operating frequency of 50 Hz. The total length of
high voltage transmission line as of November 2007 is 30,580 circuit-kilometers. The total

2.2 Additional and Updated Information for the Revision of PDP 2007
Additional and updated information and assumptions used for the revision of
PDP 2007 are as follows:
2.2.1 The March 2007 Load Forecast was reviewed to cope with the actual
energy consumption in the year 2007, of which slightly lower than the projection. The
estimated consumption of 2007 based on the record of the first 11 months was used instead
of the forecast figures while the future growth rates during 2008-2021 were kept as March
2007 forecast. No revision was made on the peak demand forecast. The amended demand
forecast is shown in Appendix 5.
2.2.2 The amount of natural gas available for power generation was revised
according to the estimate of PTT Plc. made in November 2007. The new estimates are:
Year 2010 2014 2021
Quantity (mmcfd) 2,337 2,993 3,808
(See Appendix 6 for more details)
2.2.3 The long-term price estimates of natural gas, imported coal and dieseloil were adopted from the estimate of the Energy Policy and Planning Office (EPPO) used
for the evaluation of IPP proposal. The revised forecast of domestic lignite price was made
by EGATs Fuel Management Division.
2.2.4 The capacities of the new IPP generating units were revised inaccordance with the announcement of successful bidders by EPPO on December 7, 2007
but the expected commercial operation dates (COD) were adjusted from the bidders
proposal to be matched with the demand forecast. The selected proposals and adjusted
CODs are:

2.2.5 In addition to the total existing power purchase from SPPs (FirmContract) of approximately 2,300 MW, the total amount of new capacity from SPPs (Firm
Contract) during 2007-2021 was kept at 1,700 MW to be complying with the total amount
of 4,000 MW approved earlier by the NEPC.
The total amount of proposed power sell from SPP (Firm Contract) for
the new solicitation in 2007 was far exceeded the target of 500 MW for co-generation
plants and 530 MW for renewable plants. The selection was made based on the capability
of the transmission networks to accommodate the power purchased. The total amount of
power purchase from the selected proposals was 760 MW from co-generation power plants
for the COD during 2012-2016 and 335 MW from renewable power plants for the COD
during 2009-2012. The details of power purchased from SPPs (Firm Contract) are shown
in Appendix 7.
2.2.6 The expected energy purchased from the existing 303 MW SPPs (Non-firm Contract) of 691 GWh/Year was also included as a part of energy generation. Thedetails are shown in Appendix 8.
2.2.7 The power purchased from the IPP projects of neighboring countriesthat EGAT could reach the agreements with the project developers in term of power
purchase agreements (PPA) or the Memorandum of Understanding on Tariff Setting
(Tariff MOU) were included. These projects are:
a) The projects with the PPA signed are Nam Ngum 2 (597 MW) andTheun Hinboun Expansion Project (210 MW); and

3. Power Demand Forecasting
The load forecast used for the preparation of the PDP 2007: Revision 1 was
amended from the March 2007 Load Forecast prepared by Thailand Load Forecast
Subcommittee. Only the forecast of energy demand from 2008-2021 was amended to cope
with the deviation from the actual consumption of 2007 to the forecast of corresponding
year. The estimated consumption of 2007 based on the record of the first 11 months was
used instead of the forecast figures while the future growth rates during 2008-2021 were
kept as forecasted in March 2007. There is no amendment for the peak (MW) demand
forecast.
The amended energy demand forecast during 2007-2021, compared to the
March 2007 forecast is shown as the following table.

4.6 Renewable Portfolio Standard (RPS)
A Renewable Portfolio Standard (RPS) is a regulatory policy that requires the
increased production of renewable energy sources such as wind, solar, biomass, etc. The
RPS was first introduced according to the resolution of the first workshop on Energy
Strategies held in August 2003 and was later applied for the preparation of PDP 2004. The
RPS mechanism was initially applied only on EGAT. Under the RPS policy, EGAT was
obliged to develop renewable energy sources not less than 5 percent of the new generating
capacity during 2008-2010. The total capacity of EGATs renewable energy plants
required by the RPS is 140.7 MW.
The first lot of renewable energy source projects of EGAT with the total
capacity of 81.7 MW was concurred by the Committee on Energy Policy Administration
(CEPA) in November 2006 and was approved by the National Energy Policy Committee
(NEPC) in December 2006. The NEPC also waived EGATs obligation to construct the
remaining 59 MW of renewable energy plants and substituted by the commitment to
purchase power from renewable energy plants developed by private power producers under
the Small Power Producer (SPP) and Very Small Power Producer (VSPP) solicitation.
This new policy was adopted for the construction of new generating units to be
commissioning from 2011 onwards. The approved EGAT renewable energy projects
comprised:

4.8 Emissions of Air Pollution from Power Plants
Based on the PDP 2007: Revision 1, the new power plants to be in operation
during the planning horizon of 2011 to 2021; consisting of:
- Combined Cycle Power Plants (Natural Gas-Fired) 8,800 MW- Coal-Fired Power Plants 4,000 MW- Nuclear Power Plants 4,000 MW- SPP (Co-generation and Renewable Energy) 1,700 MWOf the total installed generation capacity at the end of the planning horizon of
PDP, 58.1 percent is fossil-fuel-based combined cycle and thermal power plants of which
accounted for the air pollutants.
With increasing environmental awareness, the study to quantify emissions from
power plants was also conducted. The emissions from all power plants were estimated
based on fuel consumption, as well as emission factors for specific power generation
plants, for the years of 2011-2021. Based on the estimate annual generation of the existing
power plants and the new generating capacity in the PDP, the calculated total annual fuel
consumption was multiplied by the respective emission factors for four pollutants, CO2,
SO2, NOx and particulates. Emission factors used for various fuel and power plant types
are listed in Table 4.2

6. The Need for Nuclear Power Plants in Thailand
Electricity is one of the vital infrastructures to enhance the competitiveness of
the country. The electricity consumption of the country of which is supplied by both
purchases from neighboring countries and local generation, has increased steadily at an
average rate of 5.9 percent per year. Nonetheless, the production of electricity is still
highly depended on the fossil fuel. According to the PDP 2007: Revision 1, the natural gas
share of electricity generation remains around at 70 percent through the year 2012. The
generation from lignite remains relatively flat for the next 8 years and slightly decreases
very slow through the year 2021. The imported coal share increases slightly, from 8.4
percent in 2007 to 16.8 percent in 2017. Net imports of energy from neighboring countries
are expected to continue to meet a major share of total electricity demand.
Trend (in energy prices) is volatile by many factors that are difficult to predict,
such as world energy market, economic growth of the country and technologies.
Emissions of air pollutants and greenhouse gases are also important issues for the future
power generation.
Nuclear power generation is part of the worlds sources of energy mix
providing over 16% of world electricity. It is especially suitable for large-scale, base load
electricity demand. At present, nuclear power becomes an important option to meet energy
needs while achieving security of supply and minimizing carbon dioxide emissions.
Nuclear power could make a major contribution to reducing dependence on natural gas and
curbing CO2emissions in a cost-effective way, since its uranium fuel is abundant.
Asia is the region where electricity generating capacity from nuclear power is
growing significantly. In East and South Asia, there are over 109 nuclear power reactors
in operation, 18 under construction, and 110 under planning stage. The greatest growth in
nuclear generation is expected in China, Japan, South Korea and India.
EGAT as an utility responsible for power generation and transmission to supply
electricity demand of the country has been studied the advantages and disadvantages of
-
8/14/2019 Report Pdp2007 Eng
39/104
34
moving forward to the nuclear power generation. The advantages and disadvantages of
using nuclear power can be summarized as follows:
a) Advantages:- Competitive Production Cost Nuclear power is competitive with coal-
fired power plant fuel for electricity generation, despite relatively high capital costs and the
need to internalize all waste disposal and decommissioning costs. If the social, health and
environmental costs of coal are taken into accounts, nuclear will be more competitive.
Several productions of new reactor technologies will also drive the construction cost of
nuclear power plant down and further increase the competitiveness.
- Security of Fuel Supply From a national perspective, the security of
future fuel supply is a major factor in assessing its substainability. The abundance of
naturally occurring uranium makes nuclear power attractive to an energy security
standpoint. At present, the current usage of uranium is about 66,500 tU/yr. Thus the
worlds present measured resources of uranium (4.7 Mt) to be used in conventional
reactors, are enough to last for 70 years. This represents a high level of assured resources.
- Stable Fuel Price A long-term advantage of nuclear power over fossil
fuels is the low impact on fuel price increase, since a large proportion of those costs is in
the capital cost of the plant. This insensitivity to fuel price fluctuations will help stabilize
the electricity tariff.
- Low Air Pollutants and Greenhouse Cases Emission from electricity
generation is one of the major sources of air pollutants and greenhouse gases, providing
one third of the total. Coal-fired generation unit emits twice as much carbon dioxide as
natural gas-fired per unit of power at the power plant site, but hydro, nuclear power and
most renewables do not directly contribute any. On a global scale nuclear power currentlyreduces carbon dioxide emissions by some 2.5 billion ton per year (relative to the main
alterative of coal-fired generation. The development of nuclear power would substantially
reduce air pollutants and carbon dioxide emissions from power generation.
b) Disadvantages:- Radiation Risk The principal risks associated with nuclear power arise
from health effects of radiation. Nuclear power produces radioactivity that can come
into contact with the surrounding through small releases during routine plant operation,

7. Power Purchasing from Private Power Companies and Neighboring
Countries
7.1 Small Power Producers (SPPs)
The current solicitation of Small Power Producers (SPPs) is a part of
government policy to promote the utilization of natural resources for power generation and
to enhance efficiency through the co-generation process. The solicitation is announced for
the purchase of power generated from coal and natural gas-fired co-generation plants and
renewable energy such as biomass, etc. The generating capacity of each contract is still
kept within the range of 10-90 MW.
The record of SPP contracts as of November 2007 can be summarized as

7.2 Independent Power Producers (IPPs)
Independent Power Producers (IPPs) are the large scale private power
producers participating in the electricity supply industry by selling the generated power to
EGAT. The fuel used in the IPPs could be natural gas, coal or heavy oil. In contrast with
the Small Power Producers (SPPs), the generating capacity of the IPPs would be larger
than 90 MW.
The first round of IPP solicitation was announced in December 1994. Seven
power producers with the total capacity of 6,677.5 MW were selected to sell the electric
power to EGAT. Most of them are now in operation. The list of existing IPP contracts can

7.3 Power Purchase from Lao PDRThe power purchase from Lao PDR. was commenced in 1971 when the Nam
Ngum project, the first medium scale hydroelectric power plant, was in operation. The
volume of the power trade between the two countries was gradually increased and led to an
intergovernmental agreement to purchase bulk power from Lao PDR. In June 1993, the
Thai government signed a Memorandum of Understanding (MOU) with Lao government
to import power from Lao PDR. up to 1,500 MW by 2000. In June 1996, under the requestof Lao PDR., another MOU was signed for an additional power import of 1,500 MW
within the year 2006. The total amount of power purchase from Lao PDR. was later
extended to 5,000 MW and 7,000 MW after signing of MOUs in December 2006 and
December 2007 respectively.
After signing of the MOU, many private investor groups have proposed various
feasible projects that would export power to Thailand. The list of private projects for
power export to Thailand can be summarized as follows:

Memorandum of Understanding (MOU) on the power purchase from the Union of
Myanmar on 4th July 1997. According to the MOU, Thailand will cooperate with the
Union of Myanmar to encourage the purchase of power up to 1,500 MW from the power
projects in the Union of Myanmar utilizing indigenous resources particularly hydropower
and natural gas by the year 2010. EGAT as an assigned authority to implement the power
purchase program has jointly determined details of the power purchase including the
selection of projects, capacity of purchase and appropriate timing.
In May 2005, the Ministry of Energy of Thailand and the Ministry of Electric
Power (1) of the Union of Myanmar signed the MOU on the Cooperation in the
Development of Hydropower Projects on the Thanlwin and Tanintharyi River. The master
plan for the development of hydropower projects on the Thanlwin River was later prepared
jointly by EGAT and the Development of Hydroelectric Power (DHP). The master plan
indicated five potential hydropower projects on Thanlwin River as follows:

Project Installed
Capacity
1.) Ta Sang 7,000 MW
2.) Ywathit 800 MW
3.) Upper Thanlwin 4,000 MW
4.) Lower Thanlwin 500 MW
5.) Hatgyi 1,200 MW
Among these projects, only Ta Sang and Hatgyi are now under implementation.
a) Ta Sang projectThe Ta Sang Project is currently under the feasibility study stage. The site of
the project is in the southern part of San State, about 130 km from the Thai-Myanmar
border. The installed capacity was planned at about 7,000 MW. The MDX Group
Company Limited (MDX) was granted a concession from the Government of the Union of
Myanmar (GOM) to develop the project. The MDX and the Department of Hydroelectric
Power (DHP) jointly established the Ta Sang Hydropower Company Limited in April 2007
responsible for planning, designing, constructing and operating the project. The company
has submitted a tariff proposal for the power sale to EGAT. The tariff proposal is now
under negotiation.
b) Hatgyi ProjectThe site of the Hatgyi Project is located in Karen state about 45 km from Thai-
Myanmar border. The project was designed as the run-of-river hydropower project with noreservoir. The total installed capacity was planned at 1,360 MW. A portion of about 170
MW power will supply to the local demand in the Union of Myanmar while the major
portion of 1,190 MW will be exported to Thailand.
EGAT has signed the agreement with the DHP for the joint development of the
project associated with responsibility to seek co-investors. The Sino hydro Co., Ltd.
(Sinohydro) has expressed its interest in developing the project. In June 2006, EGAT and
Sinohydro signed the MOU for the cooperation in the development of the project. The

feasibility study of the project was jointly prepared by EGAT and Sinohydro. The
feasibility report was submitted to the DHP in January 2008. Sinohydro has submitted the
proposal for power sale to EGAT. The proposal is now under negotiation.
In addition to the development of hydropower projects, the pre-feasibility study
for the development of 270 MW lignite-fired power plant in Kyaing Tong was prepared by
the Sahakol Group. The project was planned as the mine mouth lignite-fired power plant
with the installed capacity of 270 MW of which about 30 MW will supply the local
demand. At present, there is no progress for the development of this project.
7.5 Power Purchase from the People Republic of ChinaThe Government of Thailand entered into a Memorandum of Understanding
(MOU) with the Government of Peoples Republic of China (PRC) in November 1998
with the intention to export power of 3,000 MW from Yunnan Province of PRC to
Thailand. Due to the economic depression of the region and the issues relating to the right-
of-way of the transmission line passing through the territory of Lao PDR., the proposed
project has been delayed.
To proceed with the MOU, the study of the project was reinitiated in 2004.
Thailand, PRC. and Lao PDR. agreed to conduct a joint feasibility study on power export
from China to Thailand through Lao PDR. The study was planned to cover technical and
economic justification of the project as well as the proposal to render an acceptable benefit
to Lao PDR. for the consent to construct the transmission line through its territory.
Nonetheless, despite of several technical and economic studies carried out, butno definite resolution was concluded due to issue relating to the price gap between the
proposed tariff by PRC. and an acceptable tariff of EGAT. All parties concerned agreed to
temporarily suspend the project.
