Germany has reached an agreement with the regions most affected by a plan to phase out the use of brown coal, or lignite, for its power plants by providing about 40 billion euros ($45 billion) in aid, a document reviewed by Reuters showed.
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat is considered the lowest rank of coal due to its relatively low heat content has a carbon content around 60–70 percent. It is mined all around the world, is used almost exclusively as a fuel for steamelectric power generation, and is the coal which is most
be feasible consequently, lignite is burned near where it is mined. A small amount is used in industrial and domestic situations, but lignite is mainly used for steam/electric production in power plants. Lignite combustion has advanced from small stokers to large pulverized coal (PC) and cyclonefired units (greater than 500 megawatt).
Lignite coal power plants compete in the meritorder with hard coal and gas plants. In the meritorder curve they are positioned as a "lowproductioncost" increment, right next to nuclear generation. Costs of renewables influence renewable generation capacity, and thus reduce the residual load. Also, besides nuclear, high carbon
