You cannot judge coal quality by eye. Two cargoes that look the same can differ widely in energy, moisture, ash and sulphur, and those differences decide what you really pay per unit of heat and whether your boiler runs well. The only reliable way is a written specification, proper sampling and laboratory analysis by an

Indonesia and Australia dominate world coal exports. Indonesia is the largest exporter of thermal coal for power plants. Australia is the largest exporter of metallurgical coal for steelmaking and the second-largest for thermal coal. Russia, Colombia, South Africa, the United States, Canada and Mongolia make up most of the rest. Where you buy from depends

Low-sulphur coal produces less sulphur dioxide (SO2) when it burns. That makes it easier for power plants, cement kilns and industrial boilers to meet emission limits, reduces corrosion in boilers and chimneys, and lowers the cost of running flue gas scrubbers. For many plants, choosing low-sulphur coal is the simplest and cheapest way to cut

Buying coal for a power plant means balancing four things: the right quality for the boiler, the lowest cost per unit of energy, secure supply and clean contract terms. Get the quality wrong and efficiency drops and maintenance rises. Get the supply wrong and the plant may run short when it matters most. This checklist

A reliable coal supply chain is built before something goes wrong. In 2026, coal buyers face falling Indonesian exports, supply disruptions such as the force majeure at Colombia’s Cerrejón mine, high gas prices that pull more demand toward coal, and volatile freight. Plants that depend on a single mine or on spot cargoes are most

Coal is still one of the world’s main energy sources. Global coal demand reached about 8.84 billion tonnes in 2025, and the IEA expects about 8.94 billion tonnes in 2026. Coal generates around a third of the world’s electricity and remains essential for steel and cement, even as renewables grow quickly. The market is now

In a blast furnace steelworks, coal quality goes straight into the cost and quality of the steel. High-grade coking coal makes strong, clean coke, which keeps the furnace running smoothly, lowers the amount of coke needed per tonne of iron and keeps impurities out of the metal. Poor coal does the opposite: more slag, more

Coal affects the environment at every stage: mining, transport, storage and, above all, combustion. Burning coal releases carbon dioxide, sulphur dioxide (SO2), nitrogen oxides (NOx), particulates and mercury. Coal has the highest CO2 emissions per unit of energy of the major fossil fuels. Industrial users cannot remove every impact, but proven technologies and better coal

The largest coal suppliers to power plants are national giants such as Coal India and China Shenhua, which mainly serve their home markets, and international miners and exporters such as Glencore, Peabody and Indonesia’s Bumi Resources and Adaro Andalan. For buyers who import, the supplying country matters as much as the company: Indonesia and Australia

The biggest savings in coal buying rarely come from haggling over the price per tonne. They come from buying the right grade for your plant, comparing offers on cost per unit of energy, cutting freight and port costs, and avoiding expensive quality problems. In a year like 2026, when Newcastle coal rose from an average
