The objective of the present work is the assessment of the lignite contribution to the energy balance of Greece, according to the creation processes and the chronological classification.The lignite deposits known so far in Greece have been discovered and researched from the scientists of IGME in the course of evolution since 1948 (Greek Geological Survey), 1950 (Institute of Geology and Surface Research), 1973 (National Institute of Geological and Mineral Exploration) and finally in its current form in 1976 (Institute of Geology and Mineral Exploration) and are divided into (a) "productive", (b) future "productive" and (c) no financial interest in power generation. A project, co-financed by the Greek Government and the European Union, is currently implemented, aiming at the recovery of the latter in non-electrical purposes with very good results in the first
