Indonesian coal

Resources and coal deposits are abundant in Indonesia, mostly in the islands of Sumatera and Kalimantan. Indonesian coal typically has high levels of volatile matter and medium calorific values (CV of 5,000–7,000 kcal/kg). Coal is among the cleanest in the world and is therefore a more environmentally favourable solution or blending material for coal-fired power plants due to its low ash and sulphur levels.

Because of the country's archipelagic geography and geological structure, coal deposits frequently have thick seams that are close to the surface, making open-mining methods with low stripping ratios feasible. Additionally, transportation to coal terminals or transshipment locations is easily accessible via rivers and oceans. Asia is the coal market's largest consumer.
