Thailand Power Development Plan 2015-2036

To ensure power system reliability of subsystem areas in terms of generation,
transmission, and distribution, 2 areas which have high possibilities of power shortages were
considered thoroughly.
Ensuring power system reliability in Southern of Thailand
Power demand in southern of Thailand would grow 3 percent annually; therefore,
3 power plants will be added during 2019-2024 as the followings:
In 2019, Krabi Coal-fired Power Plant
In 2021, Thepa Coal-fired Power Plant unit 1
In 2024, Thepa Coal-fired Power Plant unit 2
800 MW
1,000 MW
1,000 MW
Ensuring power system reliability in Metropolitan area and
central of Thailand
Electricity consumption of metropolitan area - the country’s largest economy area
- acquired the largest portion accounting for 30 percent of the total electricity consumption.
However, relying on power from other areas, and lacking its own capacity, the area has been
confronted with the challenge of the continuously growing power demand. Therefore,
power plants are needed to be developed to maintain power system reliability in the area
during 2019-2025 as the following:
In 2019, replacement of South Bangkok Thermal Power Plant
unit 1-5 1,300 MW
In 2019, replacement of Bang Pakong Thermal Power Plant unit 1-2 1,300 MW
In 2022, replacement of South Bangkok Combined Cycle Power Plant
unit 1-2 1,300 MW
In 2023, replacement of Wang Noi Combined Cycle Power Plant
unit 1-2 1,300 MW
In 2025, replacement of Wang Noi Combined Cycle Power Plant
unit 3 1,300 MW
2-5
