Several countermeasures are developed from various fields of responsibility in order to provide the sufficient and sustainable energy policy. This paper reviews the development of energy service company (ESCO) in Thailand which is expected to be an important player for the policy of energy conservation and efficiency. In addition, the strategic management of ESCO under the roles of Thai government, private organizations and ESCOs are also analyzed with the current countermeasures and the future trend measures by considering three options of energy performance contracting (EPC). The results of analysis show that the strategic management of ESCO mainly depends on the directive of Thai government especially the enforcement of law and regulation. The ESCO with guaranteed saving contract will be dominant player if the law and regulation are effective enforced in the future. Moreover, the ESCO with shared saving contract will be the highest feasibility under the fully supported financial; however, the participation of the ESCO with consultant ontract will decrease with significant level. Finally, the strategic management of ESCOs in Thailand is presented.
