Coal was first discovered in Nigeria in 1909 at the Udi Ridge in Enugu by a British mines engineer, Albert Kitson. Kitson had been prospecting for silver. By 1914, the year of Nigeria's amalgamation, the first consignment of coal made its way to the United Kingdom from the newly created ports at Port Harcourt.

Coal is used as fuel and in industrial production of tar, gas and non edible oils. Arguably the most singular impediment to the attainment of the vision 20:2020 in Nigeria is power{ electricity} because of the direct bearing it has on other economic indicators like unemployment rate and low capacity utilization in the manufacturing sector.

According to , the company mines 40 million metric tons (MMt) of marketable coal per year (mostly used at the Secunda CTL plant) and exports about 2.8 MMt per year. distributes and markets natural gas produced in Mozambique that is exported to South

Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coal-fired thermal power plants, the raw coal is first pulverized to the shape of flour before it is force-fed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated from the coal.
