A master program focuses on the adequacy of power system to enhance various infrastructure development in accordance with the National Economic and Social Development Plan. As the third revision of PDP 2010, it is in line with the Alternative Energy Development Plan (AEDP) (2012-2021) and the 20-Year Energy Efficiency Development Plan (EEDP) (2011-2030). Two main purposes of the Thailand power development plan formulation are to maintain power system security and to provide adequate and reliable electricity supply. Compared to PDP2010 (Revision2), adjustment of peak demand forecast has been made to reflect 3,494 MW or 6.27 percent lower than previous estimation. Besides, Thailand should have the proper level of reserve margin at not less than 15 percent of peak power demand. Due to security concern, scheduled commercial operation date (SCOD) of the first unit on nuclear power project was delayed three years from 2020 to 2023.
Target values of generating capacities can be summarized as follows:
- Total added capacity during 2012-2030: 55,130 MW
- Total retired capacity during 2012-2030: 16,839 MW
- Grand total capacity by end of 2030: 70,686 MW
Total added capacity during 2012-2030 can be further broken down to these categories:
1. Renewable energy power plants: 14,580 MW
- Power purchase from domestic: 9,481 MW
- Power purchase from neighboring countries: 5,099 MW
2. Cogeneration: 6,476 MW
