Abstract: Electricity supply security has become one of the main concerns in the national energy supply plan. Diversification of fuels used for electricity generation is therefore a major tool for energy acquisition. The fuels used for electricity generation are natural gas, coal, hydropower, oil, imported from neighboring countries, and renewable energy.
There have been four major groups of generators in Thailand, who are Electricity Generating Authority of Thailand (EGAT, a state enterprise), Independent Power Producers (IPPs), Small Power Producers (SPPs), and Very Small Power Producers (VSPPs). In addition to those major groups of producers, there have been import and exchange of electricity with neighboring countries, such as Lao PDR and Malaysia.
The latest Power Development Plan of Thailand (PDP 2018), issued in April 2019, provides detailed plan of supply of electricity until 2037. The plan includes electricity supply from fossil fuels and renewable energy, which are subjected to different generation costs. Possible price duration curves for annual supplies in 2037 is derived, and the average generation costs from 2018 till 2037 are estimated. The cost proportion electricity from renewable energy is planned to increase from 7.5% in 2018 to 21.7% in 2037, which indicates a significant substitution of renewable energy for traditional fossil fuels.
Keywords: Power development plan, renewable energy, price duration curve, electricity generation cost
