Mae Moh Mine is the largest open-pit lignite mine in Southeast Asia, with a total mining area of 9,260 acres and external dumping area of 10,240 acres. It is located 630 kilometers from Bangkok in Mae Moh district, Lampang province. In 1953, an abundant lignite resource was found at Mae Moh basin. That contributed to the project to construct Mae Moh lignite power plants. It produces and supplies lignite to Mae Moh power plants to generate electricity at a comparatively low cost. At present, sixteen million tons of coal per year is produced and transferred to 10 units of the Mae Moh Power Plants, with a combined total power generation of 2,400 Megawatt.
