         In 1971, in the reign of King Rama VI, it was found that there were lignite sources in the area of Mae Moh District in Lampang Province and Klong Khanan District in Krabi Province. In the reign of King Rama VII, these lignite sources were reserved for official use only.
         In 1954, a royal decree was issued to establish the Lignite Authority to actively operate the Mae Moh Lignite Mine. The Mae Moh Mine had been producing and selling lignite to tobacco factories in the north as well as to railways factory and cement factory. In 1968, the Electricity Generating Authority of Thailand was established by the promulgation of the Electricity Generating Authority of Thailand Act, B.E. 2511 (1968) which merged the assets and operation of Lignite Authority, Yanhee Electricity Authority and the Northeastern Electricity Authority. Since then the Mae Moh Lignite Mine which is the largest mine of Thailand has been operated under the responsibility of EGAT.
         On August 17, 1972, EGAT started the construction of Mae Moh Power Plant Units 1-2 with the installed capacity of 75 MW each and expanded the Mae Moh Mine to increase its production.


         The guest houses provide the visitors with natural peacefulness amid the mountains and beauty of various species of trees.

         The club house is where the visitors can enjoy their food and the view of the mine and golf course.
