    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

    number of high voltage substations is 207 with total transformer capacity of 69,031 MVA.

    The summary of transmission line length and number of EGATs substations classified by

    voltage level are shown in table below :

    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:

    Total Capacity COD

    - Power Generation Supply 1,600 2015

    Subtotal 3,200

    Total 4,400

    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

    (1,043 MW), and Hong Sa (1,473 MW).

    Other projects that the proposals for power sell are under negotiation,

    such as Hutyi Hydroelectric Project, Koh Kong Coal-fired Power Plant Project and Ta

    Sang Hydroelectric Project, will also be included in the PDP after the agreements can be

    reached.

    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:

    - Small Hydropower Plants 78.7 MW

    - Solar Energy Power Plant 1.0 MW

    - Wind Energy Power Plants 2.0 MW

    81.7 MW

    4.7 Coal Supply Plan for EGATs Coal-fired Power Plants

    As a part of EGATs implementation plan of the four units of coal-fired power

    plants to be in operation in 2015-2017, EGAT is now engaging with the potential coal

    producers in Indonesia, Vietnam and Australia for the supply of high quality coal

    throughout the power plant lives.

    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

    The estimate of air pollutants from power plants from 2008-2021 (based on the

    PDP 2007: Revision 1) which is compared to the estimate of PDP 2007 is shown in Table

    4.3.

    The study shows that there is no significant difference in the SO2, NO2 and

    particulate air pollution between the two PDPs. However, there is a substantial reduction

    in emissions of CO2as a result of higher power import from neighboring countries.

    Pakong Power Plant, Chachoengsao Province. The project is aimed to supply the electric

    power to Bangkok Area and vicinity via the connection of 230 kV Bang Pakong-Khlong

    Dan-Bang Phli Lines. The project was approved by the Cabinet in July 2006. The

    generating unit comprises 719 MW combined cycle block. It is scheduled to be

    commissioning in March 2009.

    5.9 North Bangkok Combined Cycle Power Plant Block 1 ProjectThe project is aimed to maintain power supply capability of Bangkok Area and

    vicinity after the decommissioning of the aging North Bangkok Thermal Power Plants

    Units 1-3. The project comprises 685 MW block of natural gas-fired power plant being

    constructed at the existing site of North Bangkok Power Plant at Bang Kruai Subdistrict,Nonthaburi Province. The project was approved by the Cabinet in December 2006. The

    natural gas supply will be provided through the PTTs pipe line being constructed under

    the Sai Noi-North Bangkok and South Bangkok Project. The commercial operation is

    planned to be in March 2010.

    5.10 Transmission System Development for Power Purchase from Nam Ngum 2Hydroelectric power Project

    The Nam Ngum 2 Hydropower Project is one of the large-scale projects in Lao

    PDR., aimed to export the electric power to Thailand under the MOU between the two

    countries. The total capacity of the project is 615 MW. Under the Power Purchase

    Agreement (PPA) between EGAT and the Southeast Asia Energy Company Limited

    (SEAN), the project developer, EGAT will purchase 597 MW power with an averaged

    annual energy of 2,310 GWh/Yr after completion of the project in December 2010.

    The transmission line links between the project and EGATs network will be

    made via the 230 kV Nam Ngum 2-Na Bong (in Lao PDR.)-Udon Thani 3 double circuit

    Lines. However, in view of the fact that EGAT has also committed to purchase power

    from other IPP projects in the central part of Lao PDR., of which the transmission line

    links can be shared to minimize the construction cost, the line section from the proposed

    site of Na Bong Substation to the border and from the border to EGATs Udon Thani 3

    Substation will be designed as 500 kV lines. Prior to the commissioning of other projects,

    the Na Bong Substation will not be constructed and the lines will be operated at 230 kV of

    voltage level. The Na Bong Substation will be constructed in a later stage and be designed

    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

    follows:

    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

    be summarized as follows:

    On 27th June 2007, the Ministry of Energy (by Energy Policy and Planning

    Office, EPPO) announced the second solicitation for proposals from independent power

    producers for the supply of power to EGAT during 2011 to 2014 with the total capacity of

    3,200 MW.

    The ranking of bid proposals were made according to the evaluation of

    levelized unit price of each bidder. Among 20 qualified bid proposals with the total

    capacity of 17,407 MW, 4 successful bidders were selected by EPPO and the list was

    announced on 19th October 2007. Due to the attractive unit price proposed by the coal-

    fired bidders, two coal-fired bids with total capacity of 1,200 MW were also selected in

    addition to the two successful gas-fired combined cycle bids of which made the cumulative

    capacity of the new IPPs became 4,400 MW. The list of selected bidders and their

    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:

    7.4 Power Purchase from the Union of MyanmarThe government of Thailand and the Union of Myanmar have entered into the

    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:

    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

  • 8/14/2019 Report Pdp2007 Eng

    46/104

    41

    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.
