Indonesia is one of the world's largest producers and exporters of coal. Since 2005, when it overtook Australia, the country is the leading exporter in terms of thermal coal. A significant portion of its exported thermal coal consists of the medium-quality type (between 5100 and 6100 cal/gram) and the low-quality type (below 5100 cal/gram) for which large demand originates from China and India.
- According to information presented by Indonesia’s Ministry of Energy and Mineral Resources, Indonesian coal reserves are estimated to last around 83 years if the current rate of production is to be continued.
- Regarding global coal reserves, Indonesia currently ranks 9th, containing roughly 2.2 percent of total proven global coal reserves according to the most recent BP Statistical Review of World Energy.
- Around 60 percent of Indonesia’s total coal reserves consists of the cheaper lower quality (sub-bituminous) coal that contains less than 6100 cal/gram.
