RATCH 2006 Message from the Chairman of the Board of Directors

ç...With outstanding operating performance, consistent project development and its responsive and competitiveness, it can be assured that the Company will continue to develop and achieve consistent progress in our business operations....é

Message from the Chairman of the Board of Directors Dear Shareholders Year 2006 was marked as an auspicious time for Thailand and Thai people as the entire country have celebrated the 60th Anniversary of His Majesty’s Accession to the Throne. The government and private sectors have jointly organized memorable, once in a lifetime celebrations that immensely impressed people not only in Thailand but also in other countries. On the other hand, 2006 was a year of structural change for the country, in terms of economy, society, environment and politics, which had direct effects on the energy business. The global oil price fluctuation had brought a massive negative impact on overall economic growth. One of the most severe nationwide flooding and changes in the government and policies have forced every organization in every sector to alter their management policy responsively. Ratchaburi Electricity Generating Public Company Limited (“The Company”), a leading electricity generating company in Thailand, had to adjust its visions, missions and policies to be in line with the government’s new energy policy. The Company has prepared for its investment expansion in order to keep its consistent growth and to implement its efficient management based on the Good Corporate Governance guideline of the Stock Exchange of Thailand (SET).

Powering the Growth Last year, the Company has invested in subsidiaries and co-invested with other companies to develop various projects, including the existing projects implemented continuously from 2005 and the new project introduced in 2006. These projects include 1) the development of Ratchaburi Power Company Limited (RPCL)’s Power Plant with 1,400megawatt production capacity in Ratchaburi province in which the Company holds 25 percent and is expected to operate in 2008; 2) the development of the Nam Ngum 2 Hydro Power Plant in Lao PDR with 615-megawatt

production capacity which commercial operation expected to be in 2013; 3) the development of the Nam Ngum 3 Hydro Power Plant in Lao PDR with 440-megawatt production capacity which is expected to be completed and start operation in 2013; and 4) the development of small renewable energy power plant which will produce electricity from the associated gas from Pratu Tao-A oil rig in Sukhothai province with 1.75-megawatt production capacity, expected to start its operation in 2007. The Company’s subsidiary, Ratchaburi Energy Company Limited has also continued with its investment in related businesses. The subsidiary invested in an alcohol manufactoring plant of Siam Ethanol Exports Company Limited, with 15 percent stake. This plant is located in Rayong province. It has a total alcohol production capacity of 30 million liters per year and will start to produce and sell alcohol in 2007.

Ready for future The Company has been preparing to bid in the Independent Power Producer (IPP) project in 2007 to cope with increasing domestic demand for electricity, in accordance with Thailand’s Power Development Plan 2007-2021. The Company has conducted a feasibility study of the projects and its potential location as well as started some community relation works to prevent possible conflicts or objection from communities against the mega-project development. The Company is now ready to participate in the bidding process and is confident that it will be able to expand the group’s electricity generation capacity constantly in the future. In addition, the Company has been prepared to expand its investment in neighboring countries, in order to achieve its goal- to become a leading electricity producer in the region.

Towards Business Excellence In 2006, the Company has restructured its organization to cope with changes and to support its business expansion in the future. Such restructure included the implementation of information system technology in human resource management to enhance employees’ morale and equitable treatment in human resource management, in accordance with the good corporate governance principle.

Continuous Growth Last year, the Company’s operating performance has grown constantly, reflecting its achievement in managing business in accordance with the Company’s policy.

These financial results clearly reflect the Company’s management and operational efficiency that increases investors’ confidence. TRIS Rating Company Limited has maintained organizational rating result on the Company and Ratchaburi Electricity Generating Company Limited-the Company’s subsidiary at the same rating level as 2005, which are “AA-” and “AA” respectively. The Company also values community relations and development of communities surrounding Ratchaburi Power Plant as a very essential composition to the success operation of the Ratchaburi Power Plant and the construction of the extension project. The Company’s commitment has earned a very strong recognition and perception from communities, community leaders, and government agencies.

Income structure of the Company, its Subsidiaries and Joint ventures in 2006 Major incomes of the Company come from dividends from Ratchaburi Electricity Generating Company Limited, whose incomes are from the 25-year Power Purchase Agreement (PPA) it has executed with the EGAT. A basic income structure under Ratchaburi Power Plant’s PPA can be divided into two major parts as follows. 1. Availability Payment (AP) The Availability Payment is set up to cover all investments which include loans, loan interest, shareholders’ returns and fixed operating expenses such as maintenance costs and administrative costs. In general, the AP will depend on whether a power plant is ready to generate and transmit power as required by the EGAT regardless whether or not the EGAT orders the plant to start distributing the power. 2. Energy Payment (EP) Ratchaburi Electricity Generating Company Limited will receive the EP as soon as it generates power and transmits the energy into the EGAT’s system. The EP consists of two parts as follows: 2.1 Fuel Payment 2.2 Variable Operating and Maintenance Payment For an income structure of the joint venture business which invests in a power-generation business; namely, Tri Energy Company Limited, in which Ratchaburi Gas Company Limited holds 50 percent therein, the Company’s income can be divided into two parts – the AP and the EP, similar to Ratchaburi Electricity Generating ’s basic income structure. For incomes of Siam Ethanol Exports Company Limited which Ratchaburi Energy holds 15 percent of its shares and which has a capacity to produce 100,000 liters or alcohol a day or 30 million liters a year under the license to produce alcohol for export, all incomes will come from the sale of 95 percent pure alcohol to overseas clients. Sales price will be based on alcohol price in the world’s markets. Siam Ethanol Exports Company Limited meanwhile, will start its and running in 2007.

RATCH 2006 The Industry & Competition

The Industry and Competition Power Consumption In 2006, power demand in Thailand reached 141,980 gigawatt-hour, 5.3 percent higher than the previous year (yet lower than the demand forecast by the Thailand Load Forecast Sub-Committee of 6.6 percent). One reason was related to the Ministry of Energy’s measures and relentless campaigns for energy conservation and efficient energy consumption. The peak load occurred on May 4, 2006 at 1.30 p.m. amounted 21,064 megawatts which 2.56 percent higher from the previous year peak load. As of December 31, 2006, Thailand installed generating capacity totaled 27,271 megawatts out of which 15,795 megawatts belonged to EGAT, 640 megawatts import, and 10,836 megawatts purchased from local IPPs and SPPs.

Overview on Developments of IPPûs and EGATûs Projects The 1,400 megawatts coal-fired BLCP thermal power plant has started its commercial operation into the EGAT’s system since October 2006. In addition, there are two Combined-Cycled Power Plants currently under construction; namely, the 1,400-megawatt Ratchaburi Power’s Power Plant (held 25 percent by Ratchaburi Alliances Company Limited) and the 1,400-megawatt Gulf Power Generation Power Plant. Besides, EGAT has been obtained an approval to construct four Combined Cycle Power Plant Projects, with total generation of 2,800 megawatts. As a result, the total generation capacity of projects currently under construction is around 5,600 megawatts and the commercial operation dates of all projects are scheduled within 2010. Currently, the Company is negotiating to invest with expected 25 percent shareholding in several overseas projects, which have signed agreements to sell their power to EGAT. These projects include the 615-megawatt Nam Ngum 2 Hydro Power Plant and the 440-megawatt Nam Ngum 3 Hydro Power Plant in Lao PDR. In addition, the Company is ready to submit a bid in the upcoming solicitation for IPP power plants in 2007 as set by the Ministry of Energy. The Company has undertaken project feasibility studies both at the existing location and new sites for being most responsive to the bidding requirements and conditions. The Company’s expansion project on the 725-megawatt Ratchaburi Power Plant Block 4 has been prepared with common facilities that will lead to competitive generating cost and eventually benefit the end users.

Energy Policy The National Energy Policy and Development Plan have been approved by the National Energy Policy Council (NEPC) and the Cabinet on November 6, 2006 and November 21, 2006 respectively. The substance related to power is summarized as follows: 1. Restructure and Improve the Energy Industry Management so as to optimize the efficiency of the national energy management. • Speed up the drafting and enforcement of the Energy Act with a view to distinctly separating the policy-making features from the regulatory ones. The regulation of the energy industry will cover the electricity and natural gas industry, and an Independent Regulatory Body will be established 2. Procure Energy so as to ensure sufficiency and security of energy supply. •

Revise Thailand's Power Development Plan: o Adjust the load forecast to be more suitable and correspond with the economic conditions so as to ensure appropriate investment in the power sector and hence adequate supply to meet the demand. o Promote greater participation of the private sector in power generation by accelerating the issuance of a request for proposals for power purchase from Independent Power Producers (IPPs). o Diversify fuel sources and types for power generation, including power purchase from neighboring countries, to ensure energy security and price stability, taking into account the generation costs, environmental impact and consumers’ benefits.

046 Ratchaburi Electricity Generating Holding Public Company Limited

3. Promote Energy Conservation and Energy Efficiency • Support the purchase of power from power producers using the cogeneration system, which is an efficient system for power generation, via the Regulations for the Purchase of Power from Small Power Producers (SPPs) and the Regulations for the Purchase of Power from Very Small Power Producers (VSPPs) at a suitable amount of purchasing capacity. 4. Promote Alternative Energy Suitable for Thailand in order to diversify fuel types and reduce dependency on energy import. • Support the purchase of power generated from renewable energy, such as agricultural residue, industrial wastes, biogas, garbage, wind and solar energy, in a suitable proportion and with appropriate purchasing prices by speeding up the announcement on the increase of purchasing capacity from VSPPs and the establishment of purchasing price adders from the prices specified in the Regulations. • Establish a public organization to carry out the promotion of renewable energy utilization in the communities to bring about tangible and sustainable outcome as its implementation would be flexible and efficient. • Support the policy study, research and development on alternative energy so as to determine practical guidelines on alternative energy development of the country. 5. Establish the Energy Price Structure so that energy pricing would be transparent, fair and would reflect the actual costs. • Revise the calculation method of the Fuel Adjustment Charge (Ft) to be more appropriate and fairer, allowing the pass-through of fuel costs and power purchasing prices under efficient operation. 6. Establish Measures Pertaining to Clean Energy to reduce the environmental impact resulting from various forms of energy industry operation. • Attach importance to the reduction of environmental impact resulting from energy business development by entrusting joint responsibility for the costs of environmental protection and solution to energy producers, distributors and consumers. •

Comply with the environmental commitments that have been ratified by Thailand in the international forums.

• Join the international cooperation in implementing environmental measures pertaining to the energy industry operation to enhance sustainable energy development. • Forge ahead the Clean Development Mechanism (CDM) to promote efficient use of energy and to enhance greater use of renewable energy. 7. Promote the Private Sector and General Public Participation in Policy-Making to create understanding and cooperation in energy development of the country. •

Promote participation in determining energy policy and measures so that energy development would be sustainable.

The policy also covers the study and research to formulate energy management that is sustainable and complies with the philosophical principle of Sufficiency Economy in energy procurement, sustainable energy development, energy efficient consumption, and promotion of competition in energy business.

The Working Group is responsible for analyzing and assessing risks, managing risks to comply with the policy set by the Company’s Board of Directors, and preparing quarterly risk management report to the Company’s Board of Directors. In recent organization restructuring, the Risk Management Department was established to coordinate risk management at functional level. The Company also provided a workshop on risk management for employees from every line function of the Company’s Group. In 2006, the Risk Management Committee reviewed both internal and external factors that may affect the Company’s ability to achieve its goals and agreed to classify the Company’s risks into three categories as follows: 1. Investment Risks mean the risks arising from project investment. 2. Financial Risks mean the risks from lack of liquidity and insufficiency of capital to invest in a project. 3. Management risks mean the risks occurred from mistakes in management, operational procedures, human errors and internal factors or situations.

Investment Risks The Company has a policy to invest in electricity generating and related businesses, taking into account the return for shareholders, employees and the public. To examine risk factors on the Company’s investment, the process is divided into four phases as follows: Phase 1: Project Selection The Company put much importance in considering risk factors related to the project selection. Those factors to be reviewed include economic, social, and political situations as well as technological changes. The projects that are in line with the Company’s policies and strategies will be selected. Phase 2: Strategic Partner Selection In deciding investment in each project, the Company thoroughly and prudently studied the feasibility and returns on investment. In selecting strategic partner, the Company would consider financial risks, conflict of interest and the policies of the potential strategic partner in order to ensure that they are in line with the Company’s investment policies and strategies. Roles and responsibilities of each party were clearly identified in order to create synergy. In addition, in this phase, the Company has to consider risks related to environment impact, financial support that enables the project to achieve its goal, all agreements with business partners, and public and community acceptance. Phase 3: Project Development The Company has four projects under development as follows: •

The construction of Combined-Cycle Power Plant Project of 1,400 megawatt generating capacity in the Ratchaburi Power Plant’s area. The project is operated by an affiliated company, Ratchaburi Power Company Limited.

•

The construction of an Alcohol-manufacturing Plant of 30 million liters per year production capacity. The project is operated by an affiliated company, Siam Ethanol Exports Company Limited.

•

The construction of a Hydro Power Plant – Nam Ngum 2 of 615 megawatt generating capacity. The project investment is made through SouthEast Asia Energy Limited.

•

The Flare Gas Fired Power Plant Project of 1.75 megawatt generating capacity. The project investment is made through Ratchaburi Energy Company Limited.

The four projects are exposed to some risks that the project might not be completed on schedule that would cost the Company extra expenses. The Company has closely followed up the project’s progress on a regular basis. The Company has nominated its representatives to be members of the Board of Directors or management of each joint venture or affiliate company to monitor the progress, and take part in setting regulations and directions of the project effectively, in order to control the budget spending and carry on the construction plan. Phase 4: Commercial Operations There are two projects already operated; the first project is 3,645 megawatt Ratchaburi Power Plant and the second one is a 700 megawatt Combined-Cycle Power Plant operated by Tri Energy Company Limited (350 megawatts out of which belongs to the Company Group). While Ratchaburi Electricity Generating Company Limited and Tri Energy Company Limited are responsible for electricity generating and operational risk management in order to maintain technical characteristics including Contracted Capacity and Contracted Operating Characteristics (COC), the Company has responsibility to follow up, review, supervise and provide support to ensure risk management complies with international standards, which will enable the Company to achieve its returns on investment target.

051 Annual Report 2006

The Companyâ&#x20AC;&#x2122;s major income is generated from the operations of Ratchaburi Electricity Generating Company Limited, the Companyâ&#x20AC;&#x2122;s major subsidiary that has a long-term power purchase agreement with EGAT, which already includes the availability payment (AP) and energy payment (EP) that covers all related risks. Therefore, the Company is confident of having constant income as projected throughout the agreement period. Although the Company the possibility that Ratchaburi Electricity Generating Company Limited may not achieve its targets is very low, the subsidiary company still have to manage its own risks as follows: 1. Availability Payment (AP) According to the Power Purchase Agreement (PPA), EGAT is obliged to pay the AP which is in line with the agreed COC while Ratchaburi Electricity Generating Company Limited is obliged to maintain technical characteristics and liable for penalty payment in case availability does not meet the contracted level. However, to minimize the risk of the revenue reduction that may occur by the penalty payment deducted from the full AP, the certain limitation on such penalty was defined in the PPA. It was stated in the PPA that in case the fine is less than the minimum payment (or 0.5 percent of the full annual AP), the fine is not subject to be paid. At the same time, the fine shall not exceed the maximum charge (or 2 percent of the full annual AP). 2. Fuel Prices The changes of natural gas prices do not affect Ratchaburi Electricity Generating Company Limited since the calculation of Energy Payment (EP) under the PPA is based on the actual price of natural gas each month. EGAT as the purchaser will take risk from the fluctuation of energy prices. However, Ratchaubri Electricity Generating Company Limited must maintain the actual Heat Rate at the level below or equivalent to the rate stated in the PPA. 3. The Heat Rate of the Plants Ratchaburi Electricity Generating Company Limited will receive a Fuel Payment, which is a part of the EP, in accordance with the Heat Rate of the plants (the rate of utilizing heat in generating one unit of electricity) specified in the PPA. The received EP will be recorded as the fuel costs in operating the power plants. Although the Heat Rate specified in the PPA covers the margin to compensate the depreciation of machines and equipment in the long run, Ratchaburi Electricity Generating Company Limited still holds certain risk on the Heat Rate in case that the actual Heat Rate is higher than the rate stated in the agreement. Consequently, Ratchaburi Electricity Generating Company Limited will be liable for the additional fuel costs. 4. Fuel Quality The quality of fuel is clearly specified in the Gas Sale Agreement (GSA). In case that PTT Public Company Limited (PTT) supplies fuel with the quality lower than that specified in the GSA, Ratchaburi Electricity Generating Company Limited is entitled to reject that fuel, and it is regarded that PTT is unable to deliver the qualified fuel. Ratchaburi Electricity Generating Company Limited does not take risk from such unqualified fuel supplied by PTT or from its rejection of the unqualified fuel since the cases do not effect the availability under the PPA. 5. Operational Cost According to the PPA, the AP will be adjusted into 2 cases; the expenses in Thai baht will be adjusted accordingly to the Thai Consumer Price Index (CPI), and the expenses in US dollars, such as expenses on imported spare parts and equipment, will be adjusted accordingly to the Manufacturers Unit Value Index (MUV Index) and to the exchange rates as EGAT will absorb the risk for the extra expenses as specified in the PPA. Ratchaburi Electricity Generating Company Limited, however, is liable for the risk in case the actual expenses adjusted and higher than the Thai CPI or the MUV Index. Nevertheless, only for the expenses on imported spare parts, if the adjusted prices are higher than the MUV Index, EGAT will share the responsibility for extra expenses in the proportion stated in the agreement.

052 Ratchaburi Electricity Generating Holding Public Company Limited

To mitigate the risk caused by the increasing prices of the plant spare parts or by the more spare parts employed than the estimated expense for improving safety and efficiency of gas turbine, Ratchaburi Electricity Generating Company Limited entered into the Contractual Services Agreement (CSA) with the Joint Ventures between General Electric International Operation Co., Inc and GE Energy Parts, Inc. The CSA of USD 451 million is effective since the signed date until the final operating date of the gas turbine according to the PPA. 6. Power Plant Operation and Maintenance According to the Power Plant Operation and Maintenance Agreement (OMA), Ratchaburi Electricity Generating Company Limited has outsourced the works to EGAT with the conditions concerning incentive and penalty that were mutually agreed and set in order to control the EGAT’s operation based on the key factors namely the Availability Payment (AP) and Plant Efficiency. In case EGAT’s operation causes the power plant the less in AP or the less in Plant Efficiency, Ratchaburi Electricity Generating Company Limited will receive a fine from EGAT as specified in the OM, which, however, may not cover such a loss in revenue as stated in the PPA. Nevertheless, since EGAT is specialized and experienced in the operation and maintenance of power plants in Thailand for more than 30 years, it is of very less opportunity that such incident occurs, except that there in any accident or machinery malfunction. In case of force majeure, Ratchaburi Electricity Generating Company Limited has an insurance covering all risks that may occur to machines, property and people, including the third party. 7. Political Risks 7.1 The Acquisition by Government Agency The acquisition by a governance agency, whether it is the physical acquisition of the power plant or the share acquisition, will be considered the Force Majeure resulted from the Government action under the PPA and Ratchaburi Electricity Generating Company Limited still have the right to receive the AP. In case the acquisition prolongs more than one year, EGAT has the right to revoke the PPA but it has to pay the revocation fee equivalent to the total sum of the Company’s remaining liabilities, retained earnings, reserved funds and shareholders’ dividend. 7.2 Legislation Changes In case the changes of laws affect the capital, revenue, or expenses of Ratchaburi Electricity Generating Company Limited in the amount exceeding the number specified in the PPA, EGAT and Ratchaburi Electricity Generating Company Limited will jointly discuss the adjustment of AP and EP. If legislation changes affect the company’s ability to abide by the PPA, the situation will be considered as an uncontrollable situation incurred by the government’s action. The Company will continue to be entitled to receive the AP.

Financial Risk 1. Financial Liquidity In financial liquidity management, the Company has taken into account the sufficiency of funds for project investment and the Company’s operations by preparing the financial plans, cash flow projection of dividends from subsidiaries and joint venture business. The business operations have been monitored closely and the financial projection and plans have been reviewed on a regular basis in order to ensure that the Company’s investment plan has been in line with the financial market situation. The Company has continuously monitored the financial market and other financial instruments to minimize financial cost and mitigate any associated risk that might occur.

053 Annual Report 2006

2. Debt Service Capability Ratchaburi Electricity Generating Company Limited, a subsidiary of the Company, has secured loans in Thai baht from six domestic financial institutions under the loan agreement dated June 23, 2005, which requires the Ratchaburi Electricity Generating Company Limited to repay the principal and interests until 2015. As of December 31, 2006, the accrued balance under the agreement is Baht 23,242,996,000. On July 29, 2005 the Ratchaburi Electricity Generating Company Limited issued and offered debenture amount of Baht 10,000,000,000 comprising three-year and five-year debentures. As of December 31, 2006, the outstanding balance of the debenture is Baht 6,500,140,000. According to the loan agreements, the subsidiary company must maintain the Debt Service Coverage Ratio at no less than 1.1 : 1. In case Ratchaburi Electricity Generating Company Limited fails to maintain the Debt Service Coverage Ratio or the loan agreements, the creditors will fine or confiscate the security, which may affect its operations. Ratchaburi Electricity Generating Company Limited has already prepared for such risks by allocate financial reserves for loans and interest payment. However, since the first initial drawdown, Ratchaburi Electricity Generating Company Limited has never failed to meet the loan covenance in all respect resulting in no such kind of default according to loan agreement. 3. Interest Rate The interest rate, as specified in the long-term loan and the five-year debentures (for the interest paid in the 3rd - 5th year) of Ratchaburi Electricity Generating Company Limited, is based on MLR rate. According to the Power Purchase Agreement (PPA) entered into with EGAT, Ratchaburi Electricity Generating Company Limited will receive its revenue with MLR indexation from EGAT, resulting in no interest rate risk. 4. Exchange Rate Though income, loans and most of the expenditures of Ratchaburi Electricity Generating Company Limited are in Thai baht, there is exchange rate risk arising from the purchase of imported equipment and spare parts. However, EGAT has compensated to the exchange rate volatility for importing cost as a part of revenue under the PPA entered into with EGAT.

Management Risk 1. Human Resource The Company realizes that employees are valuable resources and, therefore, manages well the risks related to its employees. The Company ensures effective recruitment and selection process, provides appropriate and fair remunerations and benefits to retain qualified human resource, develops human capability, and regularly reviews work process and system to support the Companyâ&#x20AC;&#x2122;s business expansion. In 2006, the Company launched an organizational restructure to be in line with the Companyâ&#x20AC;&#x2122;s business expansion. The Company continuously provided training to its employees at all levels according to the annual human resource development plan to increase their capability and potential. The action is to increase capability of its employees in all levels to be able to replace vacancies when needed and appropriate. The Company studied and reviewed its remuneration structure in order to retain and motivate qualified employees and to be competitive in the labour market. The Company also improved its Human Resource Information System (HRIS) and performance appraisal system in order to ensure that its human resource management effectively supports the Companyâ&#x20AC;&#x2122;s policy.

RATCH 2006 Future Projects

Future Projects According to the government’s policy encouraging the private sector to compete in power generation industry, it is expected that in the first quarter of 2007, the Ministry of Energy will issue a Request for Proposal (RFP) for Independent Power Producers (IPPs) to submit a power purchase proposal to the Electricity Generating Authority of Thailand (EGAT), the sole power purchaser in Thailand. The total power purchased from the IPPs will be 3,000-4,000 megawatts and commercial operation will start between 2011-2013. Aside from buying power domestically, the Thai Government also promotes the power purchase from neighboring countries such as Lao PDR, Myanmar, Malaysia, and China. On December 20, 2006, the Thai and Lao PDR governments signed an Memorendum of Understanding (MOU) where electricity purchase from Lao PDR will be increased from 3,000 megawatts up to 5,000 megawatts. The power purchase from Myanmar is expected to be approximately 1,500 megawatts. As for Thailand and Malaysia, the current purchase is at 300 megawatts and it is expected to be increased up to 600 megawatts in the near future. At the same time, the government also promotes renewable energy power plant projects such as biomass, wind and solar energy. There will be a solicitation to purchase electricity from renewable energy power plants and dispatching regulations, plant characteristics and configurations and tariffs will be specially determined for renewable power plants. In addition, the power purchase from Very Small Power Producers (VSPPs) will be increased from one megawatt to no more than 10 megawatts. As a result of the said government’s policy, the Company, as an IPP, perceives investment opportunities to expand its generating capacity domestically and internationally to increase returns to the shareholders. The modern, safe and environmental-friendly production process is focused so that the Company has determined the framework for its future power production and distribution projects as follows:

1. IPP Power Plant Projects The Company is prompt and prepared for the new IPP power plant bidding. It has processed a potential site selection, conducted feasibility studies and an environment impact assessment, prepared a financial plan and undertaken community relations work to gain acceptance from local people. To participate in the 2007 IPP bidding, the Company conducted project feasibility studies and new project development plan as follows: 1.1 Ratchaburi Combined Cycle Power Plant Block 4 The 700-750-megawatt Ratchaburi Combined Cycle Power Plant Block 4 uses natural gas from Myanmar as its primary fuel. The plant is one of the most well prepared since it has furnished with common facilities such as a demineralization plant, a wastewater treatment system and utility system. The project’s Environment Impact Assessment (EIA) report was approved by the Natural Resource and Environment Policy and Planning Office on March 7, 2005. 1.2 Tri-Energy Combined Cycle Power Plant Block 2 Ratchaburi Gas Company Limited, the Company’s subsidiary, co-developed the Tri-Energy Power Plant, Block. 2, with Texaco Thailand Energy Company One, an affiliate of Chevron Corporation, in the Tri-Energy Power Plant compound in Ratchaburi Province. The area is equipped with fundamental infrastructure and therefore ready for project development. At the same time, the project’s EIA report was approved by the Natural Resource and Environment Policy and Planning Office on November 10, 2005. 1.3 New Combined Cycle Power Plants in the Central and Eastern Region of Thailand The Company has selected a potential site in the Central and Eastern part of Thailand to develop two natural gas-fired Combined Cycle Power Plants, which critical factors for power generation for example siting, size and description of area, rules and regulations of land use in the area, possibility for area development, and support from local community, will be taken into consideration. Then, feasibility studies will be made on both technical and financial respects including the selection of Engineering Procurement and Construction (EPC) contractor. Currently, the project is being studied for its environment impact assessment (EIA).

056 Ratchaburi Electricity Generating Holding Public Company Limited

1.4 A Coal-Fired Thermal Power Plant in the Southern part of Thailand Since as much as 70 percent of the countryâ&#x20AC;&#x2122;s power plants rely on natural gas as fuel for generation, the government has a policy to increase the portion of Coal-Fired Power Plants for the sake of national power system security. The Company has searched for potential sites both in Thailand and in neighboring countries to develop a coal-fired power plant. The area will be selected based on community support and acceptance as the first prioritized factor before considering other factors related to power generation. The project is currently being studied on its technical and pricing soundness.

2. Overseas Power Plant Projects The Company is seeking investment opportunities in Lao PDR, Myanmar and Vietnam to build a power plant of which generated power may be either sold to Thailand or in those countries. At present, there is a plan to develop the following power plants in neighboring countries: 2.1 The Nam Ngum 3 Hydro Power Plant A group of project developers which the Company plans to hold 25 percent of its shares entered into an MOU with EGAT on December 18, 2006 to purchase power from the Nam Ngum 3 Hydro Power Plant. The MOU contains important criteria for further discussion in order to come up with a power purchase agreement. The project, which will be situated in the Northern part of Lao PDR, has a total production capacity of 440 megawatts and is expected to complete its construction and commercially operate by early 2013. The plant will enter into a long-term power purchase agreement with EGAT for 27 years. 2.2 A Power Plant in the Southern part of Lao PDR The Company and the firm that had an MOU with the Lao PDR Government is studying the feasibility to develop several projects concurrently of which the generated power will be sold to the lower Northeastern provinces of Thailand. When technical and financial studies reveal that the project is feasible, the Company will negotiate with EGAT on the tariff and on the long term power purchase agreement. 2.3 Power Plant Projects in Myanmar and Vietnam The Company is seeking an opportunity to invest in a Combined Cycle Power Plant and a Hydro Power Plant in Myanmar of which the generated power will be sold to Thailand. As for Vietnam, the Vietnamese Government is currently promoting foreign investors to invest in power sector since domestic supply cannot meet with local demands. The promotion includes exemptions of import duty on machines and equipment and income tax. The Company is currently negotiating with a co-investor in Vietnam.

3. Renewable Energy Power Plants Renewable energy is clean, sustainable and reduces environmental impacts. It also promotes further development of sustainable energy and decreases dependence of imported energy. The Company ranks investment in renewable energy power plant among its priorities as it is one of the governmentâ&#x20AC;&#x2122;s major policies and it has studied a feasibility to develop a wind power plant and a solar thermal power plant, which can be summarized as follows: 3.1 Wind Power Plant The Company has studied sources of wind power and monitored wind power generation technology based on wind velocity in Thailand. It also keeps updated with the technology of wind turbines suitable for speeds of wind found in Thailand as well as calculates the cost of wind power generation to determine a possibility to develop it as a source of future energy to respond to the governmentâ&#x20AC;&#x2122;s renewable energy development policy. 3.2 Solar Thermal Plant The Company plans to expand its investment into an alternative energy business, which will be based on highlyefficient technology and should be a long-term investment to increase its competitiveness in the long run. So far, it has studied and looked into several alternative energy projects for future development opportunities.

5. Leadership and Vision The Company’s directors have different skills, knowledge, capability and experience in many disciplines, which enhances management efficiency. The Company’s directors, as the leader of the organization, play a key role in leading the Company to success. The directors plan and formulate strategies and policy to increase organizational competitiveness, which means the organizational growth, increasing long-term value to shareholders, and responsibility for all stakeholders. With integrity and ethics, the Company’s directors are responsible for ensuring that the Company operation fully complies with the law, related regulations and decision made in the shareholders’ meetings, and ensuring that the executives’ management and administration are in line with the Company’s goals and preset framework for the maximum benefits of shareholders while taking into account the best benefits of society. Each of the Company’s director realizes the responsibility towards the shareholders who are the business owners and have the right to appoint the directors. The directors perform and take responsibility in operating the business for the best benefits of the shareholders, or Fiduciary Duty. Their four duties are Duty of Care, Duty of Loyalty, Duty of Obedience and Duty of disclosure. The Company’s directors maintain independence in decision making for the best possible benefits of the Company and its shareholders. The directors play a vital role in formulating, approving, and reviewing vision, mission, key policies, financial goals and budget, and strategic plans, monitoring operation results of the management to regularly keep track of

073 Annual Report 2006

business progress, providing timely advice and help in adjusting plans that may not on the right track, ensuring sufficient internal control and regular monitoring, and providing policy on appropriate risk management which is a very important and urgent policy that the Company has to implement and materialize. The directors approved annual key performance indices and evaluation criteria in the beginning of the year and required performance report on regular basis for efficient monitoring, reviewing and adjustment. By the end of the year, the indices and criteria will be used for evaluating performance of the management and the Board of Directors, which is linked to remuneration determination. The sub-committees including the Audit Committee, Risk Management Committee and Human Resources and Remuneration Committee also play crucial roles in supervising and monitoring closely the management performance. In addition to appraising the Company’s performance against the preset criteria, the Board of Directors has implemented self assessment measures since 2002. The factors considered cover many important areas, including directors’ readiness, strategy formulation and business planning, risk management and internal control, conflict of interest prevention, financial and performance report monitoring, the Board of Directors’ meeting and nomination of the Board of Directors and the management. Results were used in reviewing and improving their future work process. The Company has followed SET’s guideline which viewed that a director of a listed company should hold directorship in no more than five listed companies. However, the present Chairman of the Board of Directors (Mr. Cherdpong Siriwit) is a highly capable and has great experience in energy industry and therefore holds the position of Chairman of the Board in other listed companies, including PTT Public Company Limited, PTT Exploration and Production Public Company Limited, Thai Oil Public Company Limited, Rayong Refinery Public Company Limited, and PTT Chemical Public Company Limited, and a director of Thai Oil Power Company Limited, all of which are subsidiaries of PTT Public Company Limited. The appointment was for the benefit of directing all the companies under the PTT Group into the same direction. For the Managing Director, who holds the highest position in the Company’s management, the Company has limited his directorship in other state enterprises and listed companies to no more than five, not including subsidiaries, associated companies and joint venture business, in order to enable him to fully perform his tasks, increase opportunities to exchange experience and strengthen relationship with business partners and other organizations that will benefit the Company’s operations. To assist the newly appointed directors in their assignment, the Company provided them with a summary of the Company’s businesses, the Company Group’s structure, organizational structure, their operations, the Articles of Association, rules and regulations, key policies, Code of Conduct and directors’ rules based on the requirements of SET and SEC. Furthermore, to promote understanding of roles, duty and responsibility as well as necessary skills for the directors to do their job best as the directors of a listed company, the Company has a policy to encourage the directors to participate in seminars arranged by related organizations, such as the IOD and SET. The directors who attended trainings and seminars organized by IOD are as follows:

Operating a business based on full compliance with rules and regulations set by the government’s supervising agencies is one of the Company’s crucial principles. In the Board of Directors meetings, the management prepared information summary and presented to the Board of Directors for their acknowledgement of such announcement, rules, regulations and memorandum, both newly written and amendment version issued by SEC and SET. Directors and management perform duties as designated or as the status and title holder in the Company or as seconded in any affiliates for the Company’s benefit. In case there is any lawsuit claiming due to such performance, the Legal Department will be responsible for its defense until the case becomes final. The Company has set aside Baht 2 million a year as a reserve for loss, including damages, cost of legal defense, fines, compensations by court’s order, civil penalties as applicable by law or any other money which is considered punishment or warning where the Company will be liable for such loss if the duty is duly performed as a result of his/her authority whether or not such action is taking place now or was done in the pass unless it is a fraud or corruption which the Company shall not be responsible for any loss incurred and will demand all expenses resulting from defending such a case from the corrupted or fraudulent directors or executive officers. The Company also sent concerned staff to attend training course for Board of Directors Secretary, as well as other relevant courses, organized by the IOD. This is to improve their knowledge and understanding of their responsibility that are crucial to support the Board of Directors’ operations. When directors need more related information, they can contact the Company’s high-level executives. The Company also assigned the Corporate Secretary Department to coordinate and render the secretariat and administration works for the Company’s directors.

6. Conflict of Interests With commitment to good corporate governance practice, the Company’s Board of Directors has ensured transparency in business operations and prevented conflict of interest. To maintain transparency and prevent personal interests, the Company’s Board of Directors have implemented guidelines prohibiting directors, executives, employees, temporary staff, spouse and children who have not attained manhood from using the Company’s internal information, which is important and yet not disclosed to the public, for their own or others’ interests. Anyone breaking this rule will be disciplinarily punished. The Audit Committee has reported to the Board of Directors every quarter about connected transactions which were carefully reviewed based on SET’s rules and regulations. Such connected transactions are disclosed on page 58-63 of the Annual Report and in the Form 56-1.

7. Business Ethics The Company has introduced Code of Conduct, Code of Ethics for Executives and Code of Ethics for Employees as guidelines in its operations and actions with full concerns to the responsibility for shareholders, social and environment responsibility, ethical practices toward customers, business partners, the Company, oneself, colleagues, supervisors, subordinates, society and political sector. The Board of Directors is responsible for arranging a system to ensure the Company operates in accordance with applicable law and relevant ethical practice. The code of ethics are based on the strong belief that sustainable and successful business operations and leadership can be achieved not only through commitment to work, technology development, efficient management and corporate good governance practice but also business ethics, transparency, morale, responsibility for stakeholders, society and environment. (The three codes of conduct are published on the Company’s website.)

8. Balance of Power of Non-Executive Directors The 13-member Board comprises 12 non-executive directors (including five independent directors) and one executive director. The number of independent directors are more than one third of the entire Board. Chairman of the Board is an independent, non-executive director and is not the same person as the Managing Director. Responsibilities of the Board members are clearly identified, ensuring that the directors properly act as a representative of shareholders and there is sufficient balance of power. To enhance the Board’s efficiency, the Company has set up three Sub-Committees to assist the Board in different areas including the Audit Committee, the Human Resource and Remuneration Committee and the Risk Management Committee. Their duties and responsibilities are published on page 34-36 of the Annual Report. The Company highly places importance on the dependence in decision making of the Board of Directors for maximum benefits of the Company and overall shareholders. Every director performs his/her duties with integrity and care to protect the Company’s benefits as he/she realizes his/her status as a representative of the shareholders and the responsibility in leading, monitoring, supervising, giving advice and assistance in the management operation.

075 Annual Report 2006

To encourage the non-executive directors’ meeting, the Board of Directors provide the non-executive directors’ meeting at least once a year. In 2006, the Board organized a non-executive directors’ meeting in December 2006. The issues discussed in the meeting include directors’ self assessment and recommendations for increasing the Board’s efficiency namely the Board of Directors’ meeting, management supervision, sub-committee supervision, management’s report, business plan, internal audit system and corporate performance assessment.

9. Aggregation or Segregation of Positions The Company has clearly separated responsibilities in policy formulation, supervision, and management. The Chairman is an independent director, not the same person as the Managing Director, has no relations to the management, is the leader and plays an important role in making decision on the Company’s policy as agreed at the Board of Directors’ meeting which considered and jointly worked with the management on business goal setting. The Chairman of the Board leads and ensures the Board of Directors’ meeting is effective and efficient, by encouraging every director to participate in the meeting and openly share their opinion. The Chairman supports and regularly provides advices on business operations through the Managing Director without intervening in the management’s responsibility. The Managing Director, who holds the highest position in the management, is responsible for routine management. Scope of responsibility of the Managing Director and the person in charge of this position is clearly set. The Managing Director is obliged to manage and operate the Company in compliance with the objectives, rules and resolutions of the Board of Directors’ meeting in which independent directors participated. The Managing Director also has the authority to manage permanent and contractual employees. In managing the Company’s business, the Managing Director who reports to the Board of Directors has the authority to hire, appoint, punish, terminate, promote and adjust salaries of employees and contractual staff members. This, however, is limited to the employees or contractual staff members to whom these actions are enforced by the Board of Directors’ or the Company’s rules and regulations to be authorized and approved by the Board of Directors. The Managing Director also has the authority to set work conditions for employees and contractual staff members, order and announce direction for business operation which is neither contrary to the Company’s rules and regulations nor the Board of Directors’ resolution. The Managing Director will undertake other businesses under the Company’s rules and regulations and the Board of Director’s resolution, and sets the scope of works for employees and contractual staff members at all levels. In terms of outsiders-related actions and businesses, the Managing Director has the authority to take action on behalf of and binding to the Company except for those actions and businesses that the Managing Director or any person having conflict of interest as stakeholders or contrary party to the Company or its subsidiaries. In such case the Managing Director may take action only under approval by the Board of Directors meeting in which independent directors attended. For this action, the Managing Director may authorize other person to take action on his behalf, except in any business that may bind the Company as the borrower, buyer or order maker and involves a project worth more than Baht 30 million. Any juristic act made by the Managing Director, which violates the Company’s rules and regulations or the Board of Directors’ resolution, will not hold the Company liable, except ratification is made by the Board of Directors. The Managing Director has authority to approve the procurement not exceeding Baht 30 million each, and the donation not exceeding Baht 100,000 each. The donation not exceeding Baht 300,000 each has to be proposed for approval from the Chairman of the Board and the donation of higher value each is under the authority of the Board of Directors. When the Managing Director is not in office or not able to perform his tasks, or when the position is vacant, the Deputy Managing Directors will take charge as the Acting Managing Director as orderly appointed by the Board of Directors. The Acting Managing Director has the same authority and scope of responsibility as the Managing Director except for the authority as the member of the Board of Directors.

The remuneration is also determined to motivate and retain human resources of required knowledge, capability, skills and experience that contribute to the success of the Company Group. The directors who are assigned to take extra responsibility, such as being appointed to Sub-Committees, will receive additional remuneration. The executive director will receive remuneration as a director that is linked to both corporate and the Board’s performance. The Board of Directors’ remuneration is submitted to the shareholders’ meeting for approval on annual basis. Currently, the remuneration is classified into two types: annual bonus and meeting allowances. Remuneration of the top management is in line with the policy and criteria set by the Board, and is considered and reviewed by the Human Resource and Remuneration Committee based on the key performance indices set earlier. The Board will finally approve the remuneration of the management. As required by the SEC, the remuneration of directors and the management is revealed on page 26-27.

11. Board of Directorsû Meetings The Company annually scheduled the Board of Director’s meetings in advance. Tentatively, the meeting is organized on the third Monday of each month. Next meeting schedule was confirmed in each meeting to ensure the directors and management were informed of the schedule and were able to fix their schedule in order to achieve effective meetings. There are some additional meetings as necessity occurs. Sub-Committees’ meetings are also scheduled in advance. Meeting agenda was clearly categorized and monthly schedule was clearly prepared. The Chairman and Managing Director, who also acted as the Secretary to the Board, jointly discussed the meeting agenda to ensure the important activities were covered and informed the directors in advance as well as sent meeting notice to them beforehand.

RATCH 2006 Environmental and Social Responsibilities

Environmental and Social Responsibilities Environmental and social responsibilities are important in achieving sustainable success in our business operation. Thus, the Company requires for all of its electricity generating plants to implement sufficient environmental protection measures and to control possible impact from its activities in compliance to the related laws and safety regulations. In conjunction, the development and contribution to enhance the quality of life for people living in nearby community are implemented simultaneously. In the past year, the Ratchaburi Power Plant, operated by the Company’s major subsidiary Ratchaburi Electricity Generating Company Limited, has strictly followed the practice of prevention, correction and control of environmental impact that has been set in the Ratchaburi Power Plant’s Environmental Impact Assessment Report (EIA) approved by the National Environment Board on March 2, 1996. The Company also set its safety measures to control and prevent possible impact as much as possible. Last year, the Company was assessed under the EMS ISO 14001 version 2004 by Det Norske Veritas Company Limited, and, eventually, the Company has received the certification on July 14, 2006.

Environmental Management The Ratchaburi Power Plant has strictly followed the environmental impact reduction and environmental quality monitoring plan, and regularly prepared and provided the report on such matters to the Office of the Natural Resources and Environment Policy and Planning semiannually. Significant environmental management standards already implemented are as follows: • Continuous Emission Monitoring Systems (CEMs): the system collected emission sample from the end of smokestacks at Ratchaburi Power Plant every 15 minutes to measure and keep record of carbon dioxide, nitrogen, sulfur dioxide, carbon monoxide and dust. In the past year, the contaminated air index measured at the Ratchaburi Power Plant was under the control limit, according to the standards specified by the ministerial announcement of the Ministry of Industry B.E. 2547 on contaminated substances emitted from electricity generating and distribution plants, and the ministerial announcement of the Ministry of Science, Technology and Environment (B.E. 2539). • Air Quality Measurement: The Company has installed a measuring tool at the end of each smokestack as well as introduced Ambient Air Quality Monitoring Systems (AAQMs) by installing four permanent air quality monitoring stations in the community near the power plant for 24-hour monitoring of sulfur dioxide, nitrogen dioxide, ozone and dust smaller than 10 micron, and dust levels. The monitoring showed that the level of pollutants, especially sulfur dioxide and nitrogen dioxide in the air around the power plant was relatively low by the standards specified in the National Environment Board announcements No. 10 (B.E. 2538), No. 21 (B.E 2544), and No. 24 (B.E. 2547). • Waste Water Management: The analysis of waste water sample collected at the end of the pipes which are approximately three kilometers from the Retention Pond No. 2 before being released to the irrigation canal (Bang Pa Canal) shows that water quality index successfully met the Irrigation Department’s standards on waste water released to irrigation system, the control standards on releasing waste water from industrial plant and industrial estates, and the Ministry of Science, Technology and Environment announcement No. 23 (B.E. 2539). • Surface Water Quality: Ratchaburi Power Plant collected water sample from four locations – Mae Klong River at Ban Tha Rab, and three areas in Bang Pa Canal – before, after and at the Power Plant’s water release area. The water sample was analyzed against the quality standard of surface water under the National Environment Board announcement No. 8 (B.E. 2537). The analysis shows that the level of Dissolved Oxygen (DO) and the level of Biological Oxygen Demand (BOD) in the four water samples varied in different seasons. As a result, the Ratchaburi Power Plant has tightened its standards for monitoring surface water, especially for water in Bang Pa Canal. The Power Plant installed water quality measurement tools before and after the Power Plant’s water release point, in order to continuously monitor water qualities including PH, electricity conduction, temperature, DO and BOD levels. • Noise Control: Ratchaburi Power Plant has measured loudness at the plant and nearby community four times a year regularly. Noise measurement instruments have been installed to keep track of noise level 24-hours for three consecutive days. Results shows that the noise level occurred by the power generating procedure was below 70 decibel and

081 Annual Report 2006

the maximum noise was below 115 decibel which are within the allowed range specified in the National Environment Board announcement No. 15 (B.E. 2540).

Safety Measures To effectively prevent and reduce possible impact, Ratchaburi Power Plant carefully formulated Safety Measures that include planning and sparing sufficient space between buildings and facilities in the power plant area to prevent possible accident from spreading, and installing advanced safety equipment, especially the automatic fire prevention equipment in the area that risks of fire accident may occur while the electricity generators are operating. Sub-systems used for fire prevention in the Power Plant are listed as follow; • Fire alarm system: smoke and heat detectors were installed in every building within the Power Plant and interoperate with the automatic fire distinguishing system. When the devices detect smoke and heat, they will immediately send signal to the fire alarm and control equipment. Once there is flame, the detectors will activate the automatic fire extinguishers. Automatic water sprinklers that have been installed around transformers will immediately sprinkle water once receiving fire alarm signal. • Fire prevention branches and hydrants: were installed within the electricity generating buildings and every 100 meters on roads around the buildings. • Gas fire distinguisher: the automatic system interoperates with the fire alarm system. There are three gas fire distinguishing systems as follows: -

Carbon Dioxide Fire Prevention System is used in emergency in front of the gas turbine unit

The FM200 system is used at electricity system room. FM200 is an environmentally friendly gas that does not harm the global atmosphere

Inert gas is used when fire breaks up at generator control room.

• Foam system is located at every oil tank. The system will immediately activate when receive signal from fire alarm system. It will inject foam under oil tank to prevent fire from spreading. Sprinklers around gas tank will also spray water to cool down the tanks, preventing tanks from deforming and prevent fire from spreading to the nearby oil tanks. •

Water pumps and water resources is separated into two units as follows; -

Unit 1: pumping water from raw water reservoir, which has 1.6 million cubic meters of water. This will be used for fire accident at the Combined-Cycle Power Plant.

Unit 2: pumping water from two 8,800 cubic meter water tanks. The Unit 2 will be used in case of fire at the Combined-Cycled Power Plant

However, in case one of the water pump units does not work, water from other area can be channeled into the fire spot. In addition, the Ratchaburi Power Plant employs loss management system for its safety management within the Power Plant. This includes rules for people working in the Power Plant and employees and practice guidelines for contractors who have to work in the Power Plant area. The Company regularly train and remind its staff of safety rules that covers general safety measure, safety measure for working in high places, safety for working in poor ventilated areas, rules on working on high risk areas such as rules related to working with electricity system, and loading and unloading hydrogen, and chlorine tank change, before they start to work. In 2006, the Company upgraded the high-risk work supervision measure. In addition to strict control, the company introduced four-hour after-work monitoring system. In case that the accident prevention equipment fails to perform and the accident starts to expand, the Ratchaburi Power Plant has already prepared systematic emergency plan to limit and minimize possible losses. In its emergency plan, the plant is prepared for emergency in four areas – the Thermal Power Plants area, the Combined-Cycled Power Plants area, and another two areas surrounding production buildings and warehouse. The Ratchaburi Power Plant clearly assigns specific person to take care of each area in case of emergency. Fire drill is held regularly on yearly basis. In 2006, the Ratchaburi Power Plant held an internal fire drill, in cooperation with PTT Public Company Limited’s Pipe System Operation Center Region 5,

In my opinion, the consolidated and company financial statements referred to above present fairly, in all material respects, the consolidated and company financial position as at 31 December 2006 and 2005, and the consolidated and company results of operations, and cash flows for the years then ended of Ratchaburi Electricity Generating Holding Public Company Limited and its subsidiaries, and of Ratchaburi Electricity Generating Holding Public Company Limited, respectively, in accordance with generally accepted accounting principles.

The preparation of financial statements in conformity with Thai generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of revenues and expenses in the reported periods. Although these estimates are based on management’s best knowledge of current events and actions, actual results may differ from those estimates. An English version of the consolidated and company financial statements have been prepared from the statutory consolidated and company financial statements that are in the Thai language. In the event of a conflict or a difference in interpretation between the two languages, the Thai language statutory consolidated and company financial statements shall prevail. 2.2 Accounting standard effective from 1 January 2007 According to the notification of Federation of Accounting Professions No.26/2549 dated on 11 October 2006 and No.32/2549 dated on 3 November 2006 relating to the amendment of TAS 44 “Consolidated financial statements and accounting for investment in subsidiaries” and TAS 45 “Accounting for investments in Associates” which require the change from the equity method of accounting to cost method of accounting for the investment in subsidiaries and associates presented in the separated financial statements. In according to the cost method of accounting, income from the investment will be recognised when dividends are declared. The notification is mandatory from 1 January 2007. The Company also applies the cost method of accounting for interest in joint venture presented in the separate financial statements. 095 Annual Report 2006

2.3 Group accounting - investments in subsidiaries, and interests in joint ventures 2.3.1 Investments in subsidiaries Subsidiaries are all entities over which the Group has the power to govern the financial and operating policies generally accompanying a shareholding of more than one half of the voting rights. Subsidiaries are consolidated from the date on which control is transferred to the Group and are no longer consolidated from the date that control ceases. The purchase method of accounting is used to account for the acquisition of subsidiaries. The cost of an acquisition is measured as the fair value of the assets given up, shares issued or liabilities undertaken at the date of acquisition plus costs directly attributable to the acquisition. The excess of the cost of acquisition over the fair value of the Group’s share of the identifiable net assets acquired is recorded as goodwill. Inter company transactions, balances and unrealised gains (losses) on transactions between group companies are eliminated; unrealised losses are also eliminated unless cost cannot be recovered. Where necessary, accounting policies of subsidiaries have been changed to ensure consistency with the policies adopted by the Group. In the Company’s separate financial statements, investments in subsidiaries are reported using the equity method of accounting. A list of the Group’s principal subsidiaries is shown in Note 6. 2.3.2 Interests in joint ventures The Group’s interests in jointly controlled entities are accounted for by the equity method of accounting in the consolidated and company financial statements. The Group recognises the portion of gains or losses on the sale of assets by the Group to the joint venture that it is attributable to the other venturers. The Group does not recognise its share of profits or losses from the joint venture that result from the Group’s purchase of assets from the joint ventures until it resells the assets to an independent party. However, if a loss on the transaction provides evidence of a reduction in the net realisable value of assets or an impairment loss, the loss is recognised immediately. A list of the Group’s principal joint ventures is shown in Note 6. 2.4 Foreign currency translation Items included in the financial statements of each entity in the Group are measured using Thai Baht. The consolidated and company financial statements are presented in Thai Baht. Foreign currency transactions are translated into Thai Baht using the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currency are translated to Thai Baht at the exchange rate prevailing at the balance sheet date. Gains and losses resulting from the settlement of foreign currency transactions and from the translation of monetary assets and liabilities denominated in foreign currencies, are recognised in the statement of income. 2.5 Cash and cash equivalents Cash and cash equivalents are carried in the balance sheet at cost. For the purposes of the cash flows statement, cash and cash equivalents comprise cash on hand, deposits held at call with banks, short-term highly liquid investments with original maturity of three months or less. 2.6 Trade accounts receivable Trade accounts receivable are carried at original invoice amount less allowance for doubtful receivables based on a review of all outstanding amounts at the year end. The amount of the allowance is the difference between the carrying amount of the receivable and the amount expected to be collectible. Bad debts are written off during the year in which they are identified.

2.7 Spare parts and supplies Spare parts and supplies are stated at cost less allowance for obsolescence. Cost is calculated based on the moving average basis. The spare parts are categorised as fuel, specific spare parts and common spare parts. Specific spare parts are used for specific plant equipment in the power plant. The allowance for specific spare parts is calculated using the straight-line method to write off the balances of specific spare parts on hand at the year end over the remaining useful life of the power plant. 2.8 Investments Investments other than investments in subsidiaries and interests in joint ventures are classified as held-tomaturity. The classification is dependent on the purpose for which the investments were acquired. Management determines the appropriate classification of its investments at the time of the purchase and re-evaluates such designation on a regular basis. Investments with fixed maturity that the management has the intent and ability to hold to maturity are classified as held-to-maturity and are included in non-current assets, except for maturities within 12 months from the balance sheet date, which are classified as current assets. Purchases and sales of investments are recognised on the trade date, which is the date that the Group commits to purchase or sell the investments. Cost of investment includes transaction costs. Held-to-maturity investments are carried at amortised cost using the effective rate. A test for impairment is carried out when there is a factor indicating that an investment might be impaired. If the carrying value of the investment is higher than its recoverable amount, impairment loss is charged to the consolidated and company statements of income. 2.9 Intangible assets 2.9.1 Goodwill Goodwill represents the excess of the cost of an acquisition over the fair value of the Groupâ&#x20AC;&#x2122;s share of the net identifiable assets of the acquired subsidiary/joint venture at the date of acquisition. Goodwill on acquisitions of subsidiaries is included in intangible assets. Goodwill on acquisitions of joint ventures is included in interests in joint ventures. Goodwill is amortised using the straight-line method over its estimated useful life. Goodwill is tested for impairment and carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity include the carrying amount of goodwill related to the entity sold. 2.9.2 Development expenditure Development expenditure is recognised as an expense as incurred. Costs incurred on development projects are recognised as intangible assets when it is probable that the project will be a success considering its commercial and technological feasibility, and only if the cost can be measured reliably. Other development expenditure is recognised as an expense as incurred. Development expenditure previously recognised as an expense is not recognised as an asset in a subsequent period. Development expenditure that has been capitalised is amortised from the commencement of the commercial operation on a straight-line basis over the period of its expected benefit. 2.10 Property, plant and equipment Property, plant and equipment are initially recorded at cost. Plant and equipment are stated at historical cost less accumulated depreciation. Depreciation is calculated using the straight-line method to write off the cost of each asset, except for land which is considered to have an indefinite life, to their residual values over their estimated useful lives as follows:

5 - 25

Operating and maintenance equipment and Equipment for Wind power plant Buildings and structures

5 5 and 20

Furniture, fixtures and office equipment

5 Equipment for the Gas Turbine power plant will be depreciated when it is in use.

Where the carrying amount of an asset is greater than its estimated recoverable amount, it is written down immediately to its recoverable amount. Repair and maintenance expenses are charged to the income statement during the financial period in which they are incurred. The cost of major renovations is included in the carrying amount of the asset when it is probable that future economic benefits in excess of the originally assessed standard of performance of the existing asset will flow to the Group. Major renovations are depreciated over the remaining useful life of the related asset. Repair and maintenance expenses of equipment for the operation of gas turbines in the combined cycle power plant are according to the Contractual Service Agreement for the Combined Cycle Generating of Ratchaburi Power Plant with the Consortium of General Electric International Operations Co., Inc. and GE Energy Parts, Inc. It is recorded by using the straight-line method relating to the contract period and charged to the income statement during each financial period (Note 20). Gains and losses on disposals are determined by comparing proceeds with carrying amount and are included in operating profit. 2.11 Deferred income taxes and income taxes The Group does not recognise income taxes payable or receivable in future periods in respect of temporary differences arising from differences between the carrying amounts and tax base of assets and liabilities in the consolidated or company financial statements. Subsidiaries have certain promotional privileges from the Board of Investment, which include exemption of income tax as described in Note 16. Income tax presented in the consolidated and company statements of income relates to non - BOI promoted activities. 2.12 Borrowings Borrowings are recognised initially at the fair value of proceeds received, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost using the straight-line method, any difference between proceeds (net of transaction costs) and the redemption value is recognised in the statement of income over the period of the borrowings. 2.13 Employeesâ&#x20AC;&#x2122; benefits The Group operates a provident fund that is a defined contribution plan, the assets of which are held in a separate trust fund and managed by fund managers. The provident fund is funded by payments from employees and by the relevant Group companies. Contributions to the provident fund are charged to the consolidated and company statements of income in the year to which they relate. The Group does not recognise liabilities in respect of employee benefit potentially payable under the Thai Labour Law.

098 Ratchaburi Electricity Generating Holding Public Company Limited

2.14 Revenue recognition A subsidiary has entered into a 25-year Power Purchase Agreement with Electricity Generating Authority of Thailand (EGAT) whereby the subsidiary will deliver the Net Electrical Generation to EGAT. Revenue comprises Availability Payments and Energy Payments. Availability Payments are recognised according to the terms set out in the Power Purchase Agreement, as conditions are met essentially on a time basis of power plant operation, net amount of sales taxes and discounts. Energy Payments are calculated based on electricity delivered. Service income is recognised on the performance of services. Interest income is recognised on an accrual basis unless collectibility is in doubt. Dividend income is recognised when the shareholderâ&#x20AC;&#x2122;s right to receive payment is established. Revenue from sales and service within the Group are eliminated in the consolidated financial statements. 2.15 Dividends Dividends are recorded in the consolidated and company financial statements in the period in which they are approved by the Annual Shareholdersâ&#x20AC;&#x2122; meeting. 2.16 Provisions Provisions, which exclude the provisions relating to employee benefits, are recognised when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate of the amount can be made. Where the Group expects a provision to be reimbursed, the reimbursement is recognised as a separate asset but only when the reimbursement is virtually certain. 2.17 Segment reporting The Group engages in the power plant business through its own operations and through investments. Management considers its activities as an integrated and complementary line of business and determines that the Group has only one major business segment. Moreover, in terms of operating locations and market areas, the Group has only one geographical segment because it operates solely in Thailand. 2.18 Comparatives The comparative figures have been adjusted to conform with changes in presentation in the current year.

The original long-term loans were secured liabilities under the Loan Agreement dated 9 October 2000 which were amended on 20 June 2002 and 27 June 2003. The long-term loans are secured over land, buildings, power plant and equipment of a subsidiary. In addition, the Power Purchase Agreement, the Asset Purchase Agreement, the Major Maintenance Agreement, insurance policies and other related agreements with the lenders had been assigned as collateral in accordance with the conditions under the Loan Agreement. On 16 June 2005, the subsidiary entered into an underwriting agreement with four local financial institutions. Under the agreement, these four financial institutions had jointly agreed to underwrite the refinancing facilities totalling Baht 34,262 million, which comprised Tranche A long-term credit facilities of Baht 24,262 million, debenture facilities of Baht 10,000 million and Tranche C short-term credit facilities of Baht 10,000 million as temporary facilities before completion of debenture issuance to refinance the full amount of existing loans. On 23 June 2005, such subsidiary entered into a loan agreement with six local financial institutions which comprised Tranche A long-term credit facilities of Baht 24,262 million and Tranche C short-term credit facilities of Baht 10,000 million. On 25 July 2005, the subsidiary drew down the Tranche A and Tranche C credit facilities totalling of Baht 34,262 million to repay the full amount of the existing loans. On that day the subsidiary redeemed the mortgage and pledge as collateral of land, buildings, power plant and equipment and investment in securities toward the existing loans, and mortgaged and pledged land, building, power plant and equipment as collateral in accordance with the refinancing agreement and debentures. According to the debt restructuring, the subsidiary paid the penalty charge on prepayment of existing loans amounting to Baht 154.50 million, and write off deferred financing fee for prepayment of existing loans amounting to Baht 236.52 million, which are recorded as administrative expenses in the third quarter of 2005. During 26 to 29 July 2005, the subsidiary issued and distributed the unsubordinated debentures, bearing the name of the holders, secured, with the debenture holder representative and principal installment repayments to the general public and institutional investors. The debenture comprised Tranche B1 of Baht 7,000 million with a threeyear repayment period and a fixed interest rate of 3.67% per annum and Tranche B2 of Baht 3,000 million with a fiveyear repayment period and a fixed interest rate of 3.67% per annum for the first and second year and Minimum Lending Rate (MLR) minus 2 per annum throughout the remaining periods. The subsidiary used proceeds from issuing of debentures amounting to Baht 10,000 million to pay the full amount of Tranche C short-term credit facilities on 29 July 2005.

18. Financial instruments Foreign Currency Risk The Group has no significant foreign currency risk since the major business transactions of the Group are carried out in Thai Baht. In respect of currency exchange risk, which mainly relates to the purchase of spare parts and maintenance expenses in US Dollars, the Group manages its short-term exchange risk by entering into forward exchange contracts, normally of a maturity of no longer than 30 days. In addition, the pricing formula contained in the PPA with EGAT allows for the inclusion of the exchange risk factor relating to the purchase of spare parts and maintenance expenses.

112 Ratchaburi Electricity Generating Holding Public Company Limited

Trading for speculative purposes is prohibited. All derivative transactions are subject to approval by the managing director of each company before execution. Decisions on the level of risk undertaken are confined to the managing director of each company, which has established limits by transaction type and by counter party. Credit Risk The Group has no significant concentrations of credit risk relating to its cash and investments. The Group places its cash and investments with high quality institutions. The Group’s policy is designed to limit exposure with any one institution and to invest its excess cash in low risk investment accounts. The Group has not experienced any losses on such accounts. The Group has no significant credit risk with any single counterparty or group counterparties as the only customer of the Group is EGAT, a State Enterprise. Interest Rate Risk Interest rate risk arises from the fluctuations in market interest rates, which may have a negative effect on current and future operations of the Group. Management believes that exposure to interest rate risk is minimal because the floating interest rate according to the condition in the long-term loans agreements (Note 8) is included in the availability payment as specified in the Power Purchase Agreement (Note 20). Therefore, the Group does not enter into a hedging agreement to protect against such risk.
