Coal Business

Company’s core business is in the coal production and distribution domestically and overseas, having coal mine projects located in Indonesia as its base for coal production and distribution activities. In addition, the Company has ocean freight transport service business in Singapore to effectively support and manage coal transport for distribution in the Country or delivery to other countries.

Coal Characteristics

Coal is a fossil fuel, consisting of volatile matter, inherent moisture and important combustible mixture of carbon. After combustion with the volatile matter and inherent moisture driven out, small portion of coal ash remains. Coal is found in various forms or grades based on the contents of heating or calorific value, volatile matter and fixed carbon, representing in descending order of quality in 4 groups from (1) anthracite, (2) bituminous, (3) sub-bituminous, and (4) lignite. The indigenous coal deposits in that have been explored and extensively developed for local industries in Thailand are generally of lignite grade. Imported coal is mostly of bituminous grade which contains higher calorific value than lignite coal produced in Thailand.

The price of coal is usually determined based on the quality of coal, consisting of calorific value, moisture, volatile matter, fixed carbon, ash, sulfur and size.

Coal Production

Coal is formed in several stages from plant remains that have been compacted, hardened, chemically altered and metamorphosed by heat and pressure over millions of years. Therefore, in order to develop a coal mine, coal exploration works are required for the collection and interpretation of geological data in order to learn about the thickness of coal seams, boundary areas of the coal resource, chemical content and quality, and economic reserve estimation. The development of coal deposit is generally based on the information and data obtained from these exploration programs. Accordingly, the production of coal consists of following three major steps:

  1. Coal Exploration: The exploration program begins with the preliminary collection and analysis of the land surface and geological data at the target areas. Subsequently, fieldwork includes scout drilling to
    study the formation and type of soil and rock, and geological structure of the target areas to ascertain that there exists the coal deposit with further assessment of coal quality and reserve estimation for economic analysis to facilitate a decision for further development of the coal mine.
  2. Coal Mining: Before proceeding with coal mining operation, more detail drilling activities are required to collect and interpret necessary information and data of the mining areas; such as, coal reserves
    and quality for each of the coal seam formations including soil layers. The collected data and information will be used to determine the mine master plan which includes the analysis of mining costs and mining methods, as well as the quantity and areas for overburden removal and coal winning logistics, and also selection of suitable mining equipment and machinery.
  3. Coal Dressing: In order to attain the quality as required by the users or customers, coal extracted from the coal mining operation need to go through coal dressing process which includes crushing, sizing, sorting and washing to remove any contaminations, etc.

Coal Pricing Policy

Coal pricing is mainly determined by its heating value, similar to other type of fuels. Coal sale price for each customer varies depending on certain factors such as order volume, coal specifications such as calorific value, credit term and other conditions specified by the customer. These factors shall be used to determine the coal price fairly and similarly with all the customers. The price for imported coal is based on the agreement with each customer which can either be priced on FOB or CIF basis, or priced as delivered to the customer’s factory, etc.

Coal Distribution

For coal distribution in the domestic market, the Company directly sells coal directly to customers without going through agent. As for the overseas market, coal are sold directly to the customers or through coal trading agents, mostly on the credit term basis, of which the Company carefully provides credit terms only for the long time customers with stable financial status. For new customers, the Company protects the risk by having a letter of credit (L/C) opened by the customer. Since the start of operation in 1985, the Company has encountered very few bad debts from the sales of coal.

Competitive Strategy

The Company focuses mainly on the service and quality control of the coal products as its marketing strategy rather than relying on pricing strategy. In addition, the Company has continually developed ways to produce high quality coal by bringing in modern technology for continuing improvement of coal production and operation.


The domestic coal distribution business has been recognized as an oligopoly market with only a few numbers of operators, having group of large and small industrial customers with the major competitor is Banpu Public Co., Ltd. Nevertheless, since the Company has its own coal mines with high quality coal and decades of mineable reserves, therefore possesses sufficient competitive advantage and business potential.

Industrial Trend

Coal is the main fuel in electricity generation and can be used as a substitute for almost every kind of fuel depending mainly on the convenience of utilization and demand on heating energy. Additionally, coal reserves are higher than other types of fossil fuel. The trend of coal consumption is still growing as the price of oil and other sources of fuel are still significantly more expensive and experience more price volatility than coal. Nonetheless, coal prices had been declining significantly since year 2011 to the lowest level in 2016 in accordance with the world economy, subsequently, coal price was recovered during the second half of 2016 and climbed up to the highest level in over five years by the end of 2016 and continued to stay at a high level until the middle of 2018 before starting to decline until present as global economy began to slow down. Additionally, the Indonesian Government policy has become more stringent, especially on the Domestic Obligation Market policy, which stipulates higher portion of coal supply to the domestic consumers with lower selling price than that of export. As a result, the average coal price in 2019 was much lower than the previous year.

Despite the fact that coal market has been affected by the trade war and global industrial changes, as with other industries; nonetheless, coal fuel is a fundamental factor in the production of electricity with the lowest cost, therefore, many countries still rely on energy from coal, especially in Asian countries such as China, India, and Southeast Asian countries including Japan, South Korea, Vietnam, Malaysia and the Philippines, as there is a tendency for increasing demand of imported coal to use in coal-fired power plants that the construction have been recently completed and there are many other coal-fired power plants still under construction, except for the European region where coal usage has declined significantly. Nevertheless, the Company with subsidiary companies operating coal mining business in Indonesia should benefit from geographical advantage of Indonesia since many countries still rely on coal imports from Indonesia, while coal consumption in Indonesia also tends to increase as well. The overall energy consumption from coal is still increasing, although the proportion of coal usage has been reduced as compared to the overall energy production, especially renewable energy, being promoted to replace fossil fuels. It is expected that coal price will still fluctuate in high level according to the market conditions, global economic slowdown and impact of various incidents, including restrictions on coal production and coal supply in the world market.

Domestic Coal Business

The Company imports coal from the joint venture coal mining projects and from other sources in Indonesia for distribution in Thailand by either direct delivery and for inventory and processing before delivery to the customers at Ayutthaya Coal Distribution Center, located in Nakornluang District, Ayutthaya Province on an area of 31 rai and 29 square wah, which can support over 200,000 tons of coal inventory. The Company’s domestic coal market share in 2019 was approximately 5.4 percent of the amount of coal used in the industrial sector, excluding coal used for electricity production of independent power producer (IPP) and small power producer (SPP). The majority of domestic coal consumption in 2019 was mainly by cement industry at approximately 41 percent with the remaining 59 percent by electricity production and other industries, which excludes electricity production from the Electricity Generating Authority of Thailand (EGAT). It is expected that the consumption of coal, with lower cost per heat unit than other types of fuel, will continue to increase
in the future.

Overseas Coal Business

For more than 18 years, the Company has invested in joint venture coal mining projects in Indonesia, of which coal is imported for distribution to the domestic customers and exported to other countries especially in the Asia region market, such as India, Japan, South Korea, Taiwan and Hong Kong, etc. Coal produced by the Company has good quality with reputable brand and trusted by both domestic and overseas customers. The Company is one of the highly regarded and reliable coal companies in the Asia region.
