The Energy Policy and Planning Office (EPPO) is responsible for recommending national energy policies and plans, inclucling energy-related measures and energy conservation to ensure well-proportioned, adequate and efficient supply of energy which corresponds with the situation of the country.

          Due to the global energy crises during 1973-1975 And again during 1979-1980, the world economy had to Face problems of high inflation and high unemployment, resulting in a persistent and worldwide economic slowdown for several years. Thailand was then inevitably affected by the global situations; moreover, there was a lack of unity among a number of agencies dealing with energy matters, making it difficult to control and monitor the work execution, which led to discontinuity and ineffectiveness of energy policy formulation and administration.

          Due to the aforementioned crises, the Government under Prime Minister General Prem Tinasulanonda had given top priority to the consideration of the improvement of energy policy management system to be more unified and presented the recommended approach to the Council of Economic Ministers on 8 September 1986, i.e. to establish the National Energy Policy Council (NEPC), together with the National Energy Policy Office (NEPO) established under the Office of the Secretariat of the Prime Minister to serve as Secretariat To the NEPC, to be in charge of the formulation of Energy policies and measures. Subsequently, Prime Minister General Prem Tinasulanonda signed the office Of the Prime Minister’s Regulation on the National Energy Administration, B.E. 2529 (1986), leading to the Appointment of the National Energy Policy Council on 16 October 1986.

          Later, the cabinet Under Prime Minister General Chatichai Choonhavan passed A resolution on 6 June 1989, Concurring with the NEPC Resolution to upgrade the Status of NEPO to that of a Permanent department under the Office of the Prime Minister to serve as Secretariat to the NEPC.

           After the appointment of a new administration under the leadership of Prime Minister Anand Panyarachun, the following legislation were enacted: the National Energy Policy Council Act, B.E. 2535 (1992); the Act on Transfer of Part of Functions and Administrative Work of the Secretariat of the Prime Minister and of the Office of the National Economic and Social Development Board, Office of the Prime Minister, to the National Energy Policy Office, Office of the Prime Minister, B.E. 2535 (1992); the State Administration Act (No.3), B.E. 2536 (1993); the Act on Organization of Ministries, Sub-Ministries and Departments (No.9), B.E. 2536 (1993); and other related pieces of legislation to upgrade the status of NEPO to that of a permanent department under the Office of the Prime Minister, reporting directly to the Prime Minister.

1992

          Later on, under the administration of Prime Minister Pol. Lt. Col. Thaksin Shinawatra, the government had a policy to reform the bureaucracy of the country with a view to improving efficiency of work execution of government agencies, by dissolving dispensable agencies so as to reduce overlapping or duplicate operational procedures and establishing several new agencies to take charge of new tasks and duties which were clearer defined. To achieve this, the State Administration Act (No.5), Act (No.5), B.E. 2545 (2002), and the Act on Organization of Ministries, Sub-Ministries and Departments, B.E. 2545 (2002), were enacted. As a result, the Ministry of Energy was then established To supervise and administer energy-related matters of the country, and the National Energy Policy Office (NEPO) was transferred from the Office of the Prime Minister to be Under the Ministry of Energy and has been renamed the Energy Policy and planning Office, or EPPO, since then.
