Provincial Electricity Authority

The first town electricity system installed outside Bangkok was in Nakhon Pathom City in 1930. In 1934, the Provincial Electricity Division was set up. After World War II, a royal decree replaced the division and formed the Provincial Electricity Organisation on 16 March 1954. The PEA was then established on 28 September 1960 by the Provincial Electricity Authority Act 1960. Following the Third National Social and Economic Development Plan (1972-1975), and significantly increased electricity demand, the PEA saw rapid expansion throughout the provinces of Thailand. All provinces, districts and subdistricts in Thailand became electrified after fiscal year 1989.[3]

PEA operates a total of 945 offices in the country, with its head office in Bangkok. Electricity provision is separated into four regions according to the geography of Thailand, with three subregions per region:
