NettetLignite is the least calorific of all categories of coal (anthracite, bituminous, subbituminous, brown coal/lignite): this is due to its high moisture and volatile content and to its low carbon content. This means that lignite-fired plants are designed to burn specifically lignite and that it is expensive to turn them into coal-fired plants.
