Since 1992, the designated factory and commercial building in Thailand have to officially appoint their own personnel responsible for energy (PRE) under the Energy Conservation and Promotion Act B.E. 2535 (A.D. 1992). PRE is an important element for each designated facility to drive the energy management system and ensure its success of the program. In Thailand, one may become PRE from various methods, but most common way of becoming PRE is from PRE training programs under required educational background. This paper concludes the PRE training programs in Thailand which consists of five main curriculums as the following: 1) PRE for designated factory 2) PRE for designated building 3) Senior PRE theoretical training 4) Senior PRE practical training and 5) PRE for manager level. The first four curriculums are compulsory programs required by law while the last one is a voluntary program. The technical comparison between those five curriculums is presented. The driving mechanism to implement those five curriculums including barriers are also raised.
